[0001] This application is a Continuation-in-Part claiming priority benefit of co-pending
and commonly assigned
U.S. Patent Application No. 09/927,891 entitled "A BTE/CIC AUDITORY DEVICE AND MODULAR CONNECTOR SYSTEM THEREFOR," filed
August 10, 2001, the disclosure of which is hereby incorporated herein by reference.
TECHNICAL FIELD
[0002] This invention relates generally to auditory devices, and particularly to a hybrid
behind-the-ear (BTE)/completely-in-canal (CIC) auditory device and a modular connector
system therefor.
BACKGROUND OF THE INVENTION
[0003] Conventional earpiece auditory devices (e.g., earphones, headphones, headsets, monitors,
IFB devices, hearing aids, earplugs, etc.) are often bulky and uncomfortable for a
user to wear. In addition, typically, these devices are cosmetically undesirable.
For example, generally, use of one of these conventional devices may be easily discovered
through casual observation of the user. However, in some circumstances, users may
not want others to know they are using an earpiece auditory device. For example, oftentimes
hearing aid users do not want others to know they are using such devices. As another
example, news anchors using IFB devices may not want the device to be seen on camera.
Moreover, use of a bulky and noticeable earpiece auditory device may potentially have
more serious consequences. For example, a bulky, noticeable earpiece auditory device
may put plain-clothed security personnel at risk of being discovered.
[0004] To overcome these problems, earpiece auditory devices have been developed wherein
the entire device may be placed behind the ear of the user or within the ear of the
user. However such devices, although possibly reducing some of the conspicuousness
of the device, create their own set of problems.
[0005] For example, placing an auditory device within the outer portion of an ear canal
of a user may cause the user to experience the occlusion effect, which is a plugged
sensation that results when the ear canal is blocked and air conduction is impeded
by the introduction of at least a portion of an earpiece auditory device into the
outer portion of the ear canal. The ear canal (sometimes referred to as the external
auditory meatus) has two zones: an outer zone and an inner zone. The outer zone, sometimes
referred to as the cartilaginous region, makes up approximately two-thirds of the
total length of the ear canal. The inner zone, referred to as the bony portion, accounts
for the remaining one third of the length of the ear canal. The earlier mentioned
plugged sensation is the result of the acoustic energy created by the vibration of
the walls of the outer portion of the ear canal in response to a bone conducted signal.
H. Gustav Mueller, "CIC Hearing Aids" What Is Their Impact On The Occlusion Effect?",
The Hearing Journal, Vol. 47, No. 11, p. 29-35 (November 1994). This energy typically escapes when the ear canal is at least partially open. However,
unfortunately, when an earpiece auditory device of sufficient size is placed in the
outer portion of the ear canal, at least a portion of this energy is trapped in the
user's ear, thereby causing the above described plugged sensation. In some existing
earpiece auditory devices, a vent(s) or other means whereby bone-conducted energy
may escape the ear canal is provided (e.g., the device is designed to leave the ear
canal at least partially open), thereby minimizing or even eliminating the occlusion
effect.
[0006] In addition, certain of the existing earpiece auditory devices (of both the behind
the ear and within the ear or ear canal varieties) experience feedback problems. For
example, some conventional earpiece auditory devices are designed with a microphone
and speaker mounted to the same housing. As a result of such a design, the microphone
and speaker are mechanically coupled to each other. One notably undesirable consequence
of this mechanical coupling is electroacoustic feedback. Furthermore, in some conventional
earpiece auditory devices, irrespective of the mounting of such components, a microphone
and speaker of the device are situated in such close proximity to each other that
feedback occurs. The above discussed feedback problems increase as the gain of the
auditory device increases. As a result, the gain of such auditory devices are limited
by the electroacoustic feedback.
[0007] In the past, efforts have been made to reduce such electroacoustic feedback by, e.g.,
physically separating the microphone and the speaker used in such devices. For example,
The Volta Review January 1980, pp. 40-44, describes a hearing aid in which the receiver is separated from the main body of
the aid and mounted in an ear mold that in turn is placed in the user's ear.
[0008] While such a design may result in reduced electroacoustic feedback, it would be commercially
unacceptable. One reason for this is, similar to earlier discussions, the user will
experience the occlusion effect on account of the introduction of the ear mold into
the outer portion of the user's ear canal.
[0009] In addition to the above, existing earpiece auditory devices are typically designed
such that the electrical components of the device (e. g, the speaker, receiver, microphone,
etc., or whichever of such components are included in the particular device) are coupled
to each other via some fixed connection. For example, in at least one instance, a
speaker of an earpiece auditory device is electrically coupled (either directly or
indirectly) to a microphone, processing circuitry, and/or a transceiver of a device
via some form of fixed wiring. Such fixed wiring is typically done because of the
protection from moisture or other undesirable elements that such fixed wiring normally
provides to electrical couplings. In addition, fixed wiring is used because it occupies
little of the scarce device space.
[0010] However, as a result of such fixed couplings, assembly of the devices and/or replacement
of defective or expired parts is normally costly, time-consuming, and/or burdensome.
To illustrate, currently, when some element of an earpiece auditory device needs to
be replaced (e.g., a part has expired or is defective), in most circumstances, the
user must return the device to the manufacturer or send the device to a repair lab.
[0011] Moreover, in some circumstances, at the manufacturer or the repair lab, the device
must be taken apart, the defective or expired part(s) carefully removed, and a replacement
part or parts inserted into the device and fixed (e.g., soldered) into place. Under
such a process, it is usually several days or weeks before the auditory device is
returned to the user.
[0012] In addition, for some earpiece auditory devices (e.g., some hearing aids, some ear
plugs), at least a portion of the earpiece auditory device is normally manufactured
to the specific dimensions of a particular user's ear structure and/or the user's
intended use for the earpiece auditory device, as determined during a fitting of the
user by a technician, representative, salesperson, etc. Although there are some advantages
to this procedure (e.g., providing a desired fit to a particular user), one notable
disadvantage to customizing these devices in this manner, at least to a manufacturer,
is that such devices can then not be mass produced.
[0013] Furthermore, another disadvantage of this customizing of portions of earpiece auditory
devices to a particular customer's ear shape is that if, upon delivery to the user,
it is discovered that the fit of the auditory device is deficient in some manner,
as was the case with replacing defective or expired parts, replacement of the ill-fitting
earpiece is costly, time-consuming, and burdensome.
BRIEF SUMMARY OF THE INVENTION
[0014] The present invention is directed to an earpiece auditory device. In one embodiment,
the earpiece auditory device includes a behind-the-ear (BTE) component, preferably
being shaped to fit behind an ear of a user. In some embodiments, the BTE component
includes processing circuitry. In a preferred embodiment, the earpiece auditory device
also includes a completely-in-canal (CIC) component, preferably being shaped to fit
into the ear canal of the user in such a manner as to touch the bony portion of the
ear canal.
[0015] In some embodiments, the CIC component includes either a universal fit or a custom
fit ear mold. The custom fit ear mold can be fabricated using a rapid prototyping
technology, in which the contours of the user's ear canal are scanned, and the scan
data is used either directly or indirectly to replicate the contours of that particular
user into the custom fit ear mold. In some embodiments, the ear mold is detachably
interconnected with a speaker module, preferably using either a latching sleeve or
a detachable locking pin arrangement. In another embodiment, the speaker module is
permanently encapsulated within the ear mold. Moreover, in one embodiment, the earpiece
auditory device includes a connector physically coupling the BTE component to the
CIC component. In some implementations, the connector includes at least one end detachably
coupled to the belind-the-ear component or the completely-in-canal component.
[0016] Technical advantages of embodiments of the present invention include ease of assembly,
disassembly, reassembly, and/or the like, for an earpiece auditory device that reduces
feedback, as well as the occlusion effect.
[0017] The foregoing has outlined rather broadly the features and technical advantages of
the present invention in order that the detailed description of the invention that
follows may be better understood. Additional features and advantages of the invention
will be described hereinafter which form the subject of the claims of the invention.

novel features which are believed to be characteristic of the invention, both as to
its organization and method of operation, together with further objects and advantages

DETAILED DESCRIPTION OF THE INVENTION
[0040] The inventors of commonly assigned United States Patent No.
5,606,621 issued February 27, 1997, entitled "HYBRID BEHIND-THE-EAR AND COMPLETELY-IN-CANAL HEARING AID," the disclosure
of which is hereby incorporated herein by reference, developed a hybrid behind-the-ear
("BTE")/completely-in-canal (CIC) hearing aid. In one embodiment, the hearing aid
of the '621 application has two components: a BTE component and a CIC component. Preferably,
these components are mechanically isolated from each other. The BTE component, which
is worn behind the ear, preferably includes at least a microphone. In one embodiment,
the BTE also includes a power source, and sound processing circuitry (e.g., amplifiers,
compressors, filters, etc.). Meanwhile, the CIC component is preferably shaped to
fit into the ear canal of the patient in such a manner as to touch the bony portion
of the ear canal. In one embodiment, the CIC component contains a speaker, the speaker
preferably being operatively connected to the sound processing circuitry of the BTE
component. In a preferred embodiment of the '621 application, because the BTE and
CIC components are mechanically isolated from each other, electroacoustic feedback
is greatly reduced. Additionally, because in a preferred embodiment, the CIC component
is located so deep in the patient's ear canal as to touch the bony portion, the hearing
aid does not cause the patient to experience the occlusion effect.
[0041] A preferred embodiment of the present invention expands upon the design of the hearing
aid(s) disclosed in the '621 application. FIGURE 1 depicts an exploded isometric view
of an exemplary embodiment of a BTE/CIC earpiece auditory device of the present invention.
In the embodiment of FIGURE 1, earpiece auditory device 40 includes completely-in-canal
unit 10, connector 20, and behind-the-ear unit 30. Preferably, when in use, behind-the-ear
unit 30 is placed behind an ear of a user, while completely-in-canal unit 10 is inserted
so deep into the user's ear canal as to touch the bony portion of the ear canal.
[0042] According to the illustrated embodiment, completely-in-canal unit 10 includes ear
mold 11. Preferably, ear mold 11 is at least partially hollow on the inside. In one
embodiment, completely-in-canal unit 10 also includes speaker receiving member 12,
preferably at a first end of mold 11. Speaker receiving member 12 may be part of ear
mold 11 itself or may be attached thereto (e.g., through an adhesive, screws, a detachable
coupling, or some other fastening means). In some embodiments, receiving member 12
comprises a plate that includes opening 18. Furthermore, in one embodiment, member
12 also includes one or more speaker fastening grooves (e. g, groove 16). In addition
to or in lieu of the above, in some embodiments, speaker receiving member 12 includes
one or more mounting holes for receiving screws and/or other fastening means (e.g.,
mounting hole 9).
[0043] Ear mold 11 and/or speaker receiving member 12 may be made from hard material (e.g.,
acrylics), soft material (e.g., silicones or foam material), or some combination thereof.
In one embodiment where mold 11 is made from hard material, at least a portion of
the mold is covered with a foam boot or slip. The foam boot or slip may be fastened
to mold 11 by numerous fastening means to include an adhesive, friction, screws, etc.
Receiving member 12 may be made from the same or different material than that of ear
mold 11.
[0044] The illustrated size and shape of ear mold 11 shown in FIGURE 1 is by way of example
only, for ear mold 11 may be of various different sizes and shapes, to include the
dimensions of a particular user's ear (e.g., the ear mold may be customized/tailored
to a particular user). Ear mold 11 may also be such that it provides a universal fit
that is satisfactory for a number of users. For example, at least a portion of mold
11 may be made from foam (or similar material) or covered with a foam slip (or like
component), either of which is able to change shape (e.g., expand, compress, deform)
to meet the dimensions of the user's inner and/or outer ear. In addition, ear mold
11 may be transparent, translucent, or opaque, or some combination thereof.
[0045] In a preferred embodiment, ear mold 11 is of a particular size and shape such that
completely-in-canal unit 10 may be placed so deep into a user's ear canal as to touch
the bony portion of the user's hearing canal. In one embodiment, the ability to produce
a completely-in-canal unit of a sufficient size to place the unit so deep into the
user's ear canal as to touch the bony portion is facilitated, at least in part, by
limiting the number of elements included in completely-in-canal unit 10.
[0046] Moreover, in a preferred embodiment, in addition to ear mold 11, completely-in-canal
unit 10 includes speaker 13. Any speaker suitable for use in an earpiece auditory
device may be used as speaker 13 (e.g., earpiece device speakers available from Knowles
Electronics, Inc.). It will be appreciated that the speaker of an earpiece auditory
device is also known in the art as a "receiver". The term "speaker" is used here to
avoid confusion with other possible components of device 40 described in detail below.
[0047] In some embodiments, in addition to the above, completely-in-canal unit 10 includes
speaker fastener 14. Speaker fastener 14 may be made from any one of numerous suitable
materials to include plastics and/or metals. In one embodiment, speaker fastener 14
includes one or more projections (e.g., projection 15). Moreover, in some embodiments,
one or more of the projections of speaker fastener 14 include appendage 19. Furthermore,
in one embodiment, in addition to or in lieu of the above, speaker fastener 14 includes
one or more mounting holes (e.g., mounting hole 8) for securing speaker fastener 14
to ear mold 11 and/or receiving member 12 using screws or other fastening means.
[0048] In a preferred embodiment, the configuration of fastener 14 is such that at least
a portion of speaker 13 fits within an area, at least partially, defined by fastener
14. For example, in one embodiment, as part of assembling device 40, speaker 13 is,
at least partially, disposed within space 17 (as shown in FIGURE 4). As can be in
FIGURE 5, space 17 is, at least partially, defined by a surface of speaker fastener
14. In the embodiments of FIGURES 4 and 5, the projection(s) of fastener 14 may help
guide speaker 13 into space 17.
[0049] In some embodiments, speaker 13 is communicatively (e.g., electrically) and/or physically
coupled to speaker fastener 14. Speaker 13 and fastener 14 may be fixedly coupled,
such as the hard-wire coupling depicted in FIGURE 1. On the other hand, speaker 13
and fastener 14 may be detachably coupled, e.g., through the detachable electrical
hole and prong arrangement shown in FIGURE 5. In some embodiments (e.g., the embodiments
of FIGURES 4 and 5), at least a portion of speaker fastener 14 acts as a guard to
protect the communicative coupling between speaker 13 and speaker fastener 14 from
one or more undesirable elements (e.g., cerumen, moisture, and the like) that may
be present in the environment in which speaker 13 and fastener 14 are used. Accordingly,
preferably in such embodiments, speaker fastener 14 facilitates an insulated communicative
coupling between speaker 13 and fastener 14.
[0050] As mentioned, preferably, ear mold 11 is at least partially hollow on the inside.
Accordingly, in one embodiment, ear mold 11 may receive internally one or more other
elements of device 40. In some embodiments, at least a portion of speaker fastener
14, along with speaker 13, which may be partially disposed herein, are passed through
opening 18 in receiving member 12 and into ear mold 11 (e.g., the assembled portion
of device 40 shown in FIGURE 2). Similar to earlier discussions, in a preferred embodiment,
speaker 13 and/or speaker fastener 14 are of a particular size and shape such that
when speaker 13 and/or speaker fastener 14 are coupled to ear mold 11, the assembly
of ear mold 11, speaker 13, and/or speaker fastener 14 may be placed so deep into
a user's ear canal as to touch the bony portion of the user's ear canal.
[0051] Moreover, in one embodiment, speaker fastener 14 and/or speaker 13, are securely
(and, in one embodiment, detachably) coupled to ear mold 11 and/or receiving member
12. In some embodiments, such a secure (preferably detachable) connection is facilitated
by the projection(s) of fastener 14 engaging the fastening groove(s) of receiving
member 12. In one of these embodiments, appendage 19 of the projection(s) engages
the fastening groove(s). In addition to or in lieu of the above, speaker fastener
14 and/or speaker 13 may be secured to ear mold 11 and/or speaker receiving member
12 by passing at least a portion of a screw(s) or other fastening means through the
mounting holes of receiving member 12 and speaker fastener 14 (e.g., the assembled
portion of FIGURE 2). In a preferred embodiment, the coupling between fastener 14,
ear mold 11, and/or receiving member 12 is of sufficient strength such that unit 10
may be removed from the user's ear canal by pulling on connector 20.
[0052] Accordingly, speaker 13, fastener 14, receiving member 12, and/or ear mold 11 can
be securely fastened together. However, in some embodiments, some or all of these
elements can also be conveniently attached to and detached from each other, thus allowing
for convenient and easy assembly and/or disassembly of earpiece device 40, as well
as allowing for the replacement of any inoperative, defective, or otherwise unsatisfactory
parts with relative ease.
[0053] For instance, if speaker 13 fails for some reason (e.g., speaker 13 is defective
or the speaker simply becomes inoperative (a common earpiece auditory device malady)),
in one embodiment, connector plate 14, with speaker 13 disposed therein, may be detached
from ear mold 11, e.g., by depressing portions of ear mold 11, member 12, and/or fastener
14, thereby releasing the appendages of fastener 14, and pulling fastener 14 from
ear mold 11. In addition to or in lieu of the above, in one embodiment, speaker connector
plate 14 is detached from ear mold 11 and/or receiving member 12 by removing screws
coupling fastener 14 to receiving member 12.
[0054] Furthermore, in one embodiment, after its removal from the inside of mold 11, speaker
13 may be separated from fastener 14 through the application of a pulling force (e.g.,
where speaker 13 and fastener 14 are coupled via a hole and prong arrangement). Thereafter,
in one embodiment, the replacement speaker may be coupled to fastener 14 by pressing
the electrical prongs of fastener 14 into the receiving holes of the replacement speaker
(or vice versa). Then, in some embodiments, speaker fastener 14, and the attached
replacement speaker, may be passed through receiving member 12 until the appendages
of fastener 14 engage the grooves of receiving member 12.
[0055] In one embodiment, completely-in-canal unit 10 has an open mold configuration, meaning
the ear canal of a user is at least partially open when completely-in-canal unit 10
is inserted so deep into the user's ear canal as to touch the bony portion. Moreover,
in some embodiments, completely-in-canal unit 10 (e.g., ear mold 11) includes a vent(s)
by which sound waves may pass over and/or through unit 10. In an embodiment of completely-in-canal
unit 10 wherein unit 10 includes a vent(s), unit 10 also includes a filter to keep
cerumen, dirt, moisture, and other undesirable elements from entering unit 10.
[0056] Furthermore, in one embodiment, the dimensions of a surface of receiving member 12
are such that member 12 may be flush with a surface of ear mold 11 (as an example,
the assembled portion of device 40 shown in FIGURE 2). Moreover, in one embodiment,
at least one dimension of receiving member 12 is initially larger, in some instances
substantially larger, than a dimension of ear mold 11 (an example of such a receiving
member is depicted in FIGURE 3). Then, as part of the assembly of device 40 in such
embodiments, speaker receiving plate 12 is ground down or otherwise reduced in size,
so as to be flush with a surface of ear mold 11.
[0057] The size and shape of the elements of unit 10, as well as the arrangement of the
elements, depicted in FIGURE 1 are by way of example only, for the elements may be
of a different size and shape, as well as arranged in a manner different from that
which is depicted in FIGURE 1. Moreover, elements not depicted in FIGURE 1 may be
included in unit 10. For example, in one embodiment speaker fastener 14 or receiving
member 12 includes a retrieval line for aiding a user in retrieving and/or inserting
unit 10 into and out of the user's ear canal. Furthermore, elements included in FIGURE
1 may be absent from unit 10. For example, in one embodiment, at least one of the
elements of completely-in-canal unit 10 depicted in FIGURE 1 is included as part of
connector 20, behind-the-ear unit 30, and/or some portion of device 40 other than
completely-in-canal unit 10. For instance, in some embodiments, speaker fastener 14
is part of connector 20, rather than unit 10. In addition to or in lieu of the above,
in one embodiment, speaker 13 is part of connector 20, rather than unit 10.
[0058] In a preferred embodiment, in addition to completely-in-canal unit 10, earpiece auditory
device 40 includes behind-the-ear unit 30. In a preferred embodiment, unit 30 includes
processing module 33. In one embodiment, module 33 includes housing 37 (housing 37
preferably being made from plastic). Furthermore, in some embodiments, module 33 includes
at least one or some combination of a microphone(s), a communications link(s), processing
circuitry (which may include sound processing circuitry), and/or a power source. Preferably,
the above described elements of module 33 are integrated with housing 37.
[0059] Any microphone suitable for use in an earpiece auditory device may be employed as
the microphone(s) in embodiments of module 33 (e.g., microphones available from Knowles
Electronics, Inc.). Moreover, the microphone(s) may be either omni, directional, or
some combination thereof.
[0060] In addition, the earlier mentioned processing circuitry (which, in one embodiment,
includes sound processing circuitry) may include any and all hardware, software, firmware,
and/or the like, necessary for the intended operation of the earpiece auditory device.
As non-limiting examples, the processing circuitry may include an amplifier(s) (in
one embodiment, multi-channel and programmable), compressor(s), filter(s), packetizing
circuitry, depacketizing circuitry, modulation circuitry, conversion circuitry, and/or
the like. Such circuitry may include analog, programmable analog, digital circuitry,
and/or a combination thereof. In one embodiment, the processing circuitry processes
electrical (and/or other) signals that are to be provided to speaker 13, where the
signals are converted to acoustic waves. In addition to or in lieu of the above, in
one embodiment, the processing circuitry processes electrical (and/or other signals)
for transmission (be it wireline or wireless) to a remote device(s).
[0061] Moreover, in a preferred embodiment, the earlier mentioned communications link enables
device 40 to communicate with a remote device (e.g., via wireline and/or wireless
transmissions). In one embodiment, the communications link includes a wireless input
receiver for receiving wireless transmissions (e.g., a radio frequency (RF) receiver
or a magnetic induction coil), a transmitter for broadcasting wireless transmissions,
and/or combinations thereof (e.g., a transceiver). These wireless transmissions may
be radio RF transmissions, optical transmissions (e.g., infrared), magnetic induction
transmissions, acoustic waves (e.g., ultrasonic), capacitive coupling transmissions,
as well as other forms of wireless communications. In some embodiments, the wireless
receiver, transmitter, etc., of the communications link includes accompanying circuitry.
[0062] With respect to the above discussed power source, in one embodiment, the power source
of module 33 is a battery. In some embodiments, the power source of module 33 is re-chargeable.
Furthermore, in one embodiment, the power source is external to module 33 (e.g., an
adapter).
[0063] Preferably, the particular element or combination of elements that is included as
part of a particular embodiment of module 33, as well as the make up of each element,
depends upon the intended use of the particular embodiment of earpiece auditory device
40. For example, when earpiece auditory device 40 is to be used to convert acoustic
waves from the user's environment into representations of the acoustic waves via electrical
(and/or other) signals, whereby the signals are then processed and provided to speaker
13 (e.g. when device 40 is to be used as a hearing aid), module 33 preferably includes
at least a microphone(s), processing circuitry, and a power source.
[0064] An example of such an embodiment of module 33 is provided in FIGURE 6A. As illustrated,
at least a portion of the interior of module 33 includes a connector 60 for communicatively
(preferably detachably) and/or physically coupling module 33 to module fastener 31
(shown in FIGURE 1) and/or connector 20. In one embodiment, such a communicative coupling
is an electrical coupling. Preferably, connector 60 is communicatively (e.g., electrically)
coupled to processing circuitry 61, which may include sound processing circuitry.
In one embodiment, processing circuitry 61 is also communicatively coupled to microphone
62. Preferably, shuttle 33 also includes power source 63 (e.g., a battery).
[0065] In some of the above discussed embodiments, the sound processing circuitry of processing
circuitry 61 includes high gain circuitry. However, in some embodiments, the sound
processing circuitry may be low or no gain circuitry. Moreover, in some of the above
embodiments, device 40 may amplify some sounds, while allowing other sounds to be
provided to speaker 13 without amplification. Furthermore, in one embodiment, device
40 may allow some sounds to be provided directly to the user's ear drum without first
being converted into electrical (and/or other) signals (e.g., the earpiece device
is an open mold configuration and/or includes a vent(s)).
[0066] Furthermore, in one embodiment, the sound processing circuitry of module 33 includes
sound amplitude reduction circuitry. For example, in some embodiments, earpiece auditory
device 40 may be used as an electronic earplug or other sound reduction device. In
one of these embodiments, module 33 includes sound amplitude reduction circuitry whereby
sounds received at the microphone are reduced (sometimes greatly reduced) in volume
before being provided to speaker 13, if such sounds are not eliminated altogether
by the circuitry. Moreover, in one of these sound reduction embodiments, device 40
may reduce the volume or eliminate certain sounds, while allowing other sounds to
be provided to speaker 13 or directly to the user's ear drum (e.g., the earpiece device
is an open mold configuration and/or includes a vent(s)).
[0067] In embodiments where earpiece auditory device 40 is to be used in a manner wherein
electrical and/or other signals are to be directly inputted (either by wired or wireless
transmissions) to device 40 and/or transmitted by device 40 (in wired or wireless
form), e.g., when used as an earphone, monitor, or IFB device, module 33 preferably
includes at least the earlier mentioned communications link, processing circuitry,
and a power source. In one of these embodiments, the sound processing circuitry included
in the processing circuitry of module 33 is high gain, low gain, no gain, and/or sound
reduction circuitry.
[0068] An example of such an embodiment of module 33 is provided in FIGURE 6B. As illustrated,
at least a portion of the internal elements of module 33 includes connector 60 for
communicatively (preferably detachably) and/ or physically coupling module 33 to module
fastener 31 and/or connector 20. Similar to FIGURE 6A, in one embodiment, connector
60 is communicatively (e.g., electrically) coupled to processing circuitry 61, which
may include sound processing circuitry. However, rather than being coupled to a microphone
as in FIGURE 6A, circuitry 61 is communicatively coupled to communications link 64.
In the illustrated embodiment, shuttle 33 also includes power source 63 (e.g., a battery).
[0069] Furthermore, in embodiments where device 40 is to be used to receive and/or transmit
data or other transmissions via a wired or wireless means to and/or from a remote
device, e.g., a computer device (such as audio files, MP3 files, voice streams, video
streams, Internet broadcasts, etc.) and/or a cell phone, preferably the communications
link and/or processing circuitry of shuttle 33 is compliant with the various transmission
formats, protocols (e.g., TCP/IP, Bluetooth), and/or interfaces necessary to receive
and process the transmissions.
[0070] Moreover, in some embodiments, device 40 may be used to directly receive and/or transmit
electrical (and/or other) signals, as well as convert acoustic waves into electrical
(and/or other) signals. For example, in one embodiment, device 40 may convert the
user's voice and/or other acoustic waves from the environment into electrical (and/or
other) signals. Moreover, such signals may be processed and transmitted to speaker
13. In addition, such signals may be processed and transmitted to a remote device(s)
(e.g., a cell phone, an intercom system). Furthermore, device 40 may receive signals
from the remote device(s). In one of these embodiments, at least a portion of the
interior of module 33 resembles the embodiment of FIGURE 6A with the addition of communications
link 64 communicatively coupled to processing circuitry 61.
[0071] Furthermore, in one embodiment, in addition to module 33, behind-the-ear unit 30
includes module fastener 31. In some embodiments, module fastener 31 facilitates the
coupling of module 33 to connector 20. In one embodiment, at least a portion of module
fastener 31 is made from plastic. Moreover, module fastener 31 may be transparent,
translucent, opaque, and/or a combination thereof. In FIGURES 1 and 8, for purposes
of illustration only, a portion of fastener 31 has been removed to enable the electrical
prongs of one embodiment of device 40 to be seen..
[0072] In one embodiment, when earpiece auditory device 40 is assembled, fastener 31 is
securely (preferably detachably) coupled to module 33 (as shown in FIGURE 7). For
example, in one embodiment, fastener 31 is of such a shape that it slips over at least
a portion of module 33. Moreover, in one embodiment, fastener 31 includes one or more
fastening projections (e. g, fastening projection 34) that engage one or more fastening
notches of module 33 (e.g., notch 35) when fastener 31 is slipped over module 33 (thereby
securing the attachment). In one of these embodiments, the one or more fastening projections
include an appendage(s) for engaging the fastening notches. In addition to or in lieu
of the above, fastener 31 may be coupled to module 33 by other means (e.g., screws,
adhesives, and/or other fastening means). In a preferred embodiment, the coupling
between fastener 31 and module 33 is of sufficient strength that completely-in-canal
unit 10 may be removed from within the user's ear canal by pulling on connector 20,
without separating fastener 31 from module 33. Furthermore, in one embodiment, the
coupling between fastener 31 and module 33 is of sufficient strength that behind-the-ear
unit 30 may be removed from behind the user's ear by pulling on connector 20.
[0073] In some embodiments, module 33 and fastener 31 can be detached from and/or reattached
to each other. In one embodiment, this may be accomplished by depressing a surface(s)
of fastener 31 and pulling the two pieces apart (e.g., an embodiment where the projection(s)
of fastener 31 engage the notch(Es) of shuttle 33). In one embodiment, module 33 may
be detached from fastener 31 by removing screws coupling the two components together.
[0074] Furthermore, in some embodiments, module 33 is communicatively (e.g., electrically)
coupled to fastener 31. In one embodiment, the communicative coupling between module
33 and fastener 31 is fixed, e.g., hard-wired. In an alternative embodiment, the communicative
coupling between shuttle 33 and fastener 31 is detachable, e.g., the detachable prong
and hole connection shown in FIGURES 1 and 8. In one embodiment where fastener 31
is communicatively coupled to module 33, at least a portion of fastener 31 acts as
a guard to protect the communicative coupling between fastener 31 and module 33 from
one or more undesirable elements (e.g., moisture, dirt particles, etc.) that may be
present in the environment in which unit 30 is used (e.g., the embodiments of FIGURES
1 and 8). Thereby, in such embodiments, fastener 31 preferably facilitates an insulated
communicative coupling between the fastener and module. Moreover, in one embodiment,
the projections of fastener 31 may help align electrical prongs of fastener 31 with
receptacle holes of module 33 (or vice versa).
[0075] In addition, in some embodiments, fastener 31 includes a plurality of holes 36 that
facilitate the passage of sound through fastener 31 and/or into module 33. In some
of these embodiments, a filter 32 is included within fastener 31 to prevent foreign
and unwanted particles (e.g., dirt and moisture) from getting inside fastener 31 and/or
passing into module 33. In one embodiment, when the filter is no longer capable of
providing satisfactory protection, the filter may be replaced by separating fastener
31 and module 33 (e.g., in the manner described above), removing the old filter from
fastener 31, and placing a new filter therein. In some embodiments, rather than being
included as part of fastener 31, filter 32 is part of module 33.
[0076] Preferably, module fastener 31 and/or module 33 are shaped so as to funnel sounds
into the interior of module 33. For example, in one of the embodiments where module
33 includes a microphone, module fastener 31 and/or module 33 may be shaped so as
to funnel sounds towards the microphone.
[0077] Moreover, as mentioned, in a preferred embodiment, when in use, behind-the-ear unit
30 is placed behind the cartilage of the user's ear. In one embodiment, fastener 31
and/or module 33 are of such size and shape that they are invisible to the casual
observer when placed behind the cartilage of the user's ear. In addition, in some
embodiments, fastener 31 and/or module 33 includes (or forms) an earhook that enables
unit 30 to sit on top of the user's ear.
[0078] As discussed, in one embodiment, module 33 and fastener 31 can be securely fastened
together. However, preferably, these individual elements can be easily detached from
and reattached to each other, thus allowing for convenient assembly and disassembly,
as well as replacement of any inoperative, defective, or otherwise unsatisfactory
parts. For instance, if module 33 fails for some reason (e.g., moisture shorts the
processing circuitry), in some embodiments, module 33 and fastener 31 can be detached
from each other (in one embodiment, by depressing a surface(s) of fastener 31 and
pulling the two pieces apart). A replacement module can then be selected. Afterwards,
in one embodiment, fastener 31 can be coupled to the replacement module by slipping
the fastener over the replacement module until the projections of fastener 31 engage
the notches of the replacement module
[0079] The dimensions and arrangement of the elements of behind-the-ear unit 30 shown in
FIGURES 1 is by way of example only, as the elements may be of a different size and
shape, as well as arranged in a manner different from that which is depicted in FIGURE
1. In addition, elements not depicted in FIGURE 1 may be included in unit 30. On the
other hand, elements included in FIGURE 1 may be absent from unit 30. Furthermore,
rather than being part of unit 30, some of the elements of unit 30 depicted in FIGURE
1 may instead be part of connector 20, speaker module 10, or some portion of earpiece
auditory device 40 other than MRP module 30. For example, in one embodiment, fastener
31 is part of connector 20.
[0080] In addition to the above, in one embodiment, connector 20 physically (preferably
detachably) couples completely-in-canal-unit 10 to behind-the-ear unit 30. In a preferred
embodiment, connector 20 includes at least one end that may be detachably physically
coupled to unit 10 or unit 30. Also, in one embodiment, as part of the physical coupling
of behind-the-ear unit 30 to completely-in-canal unit 10, connector 20 communicatively
(e.g., electrically) couples completely-in-canal unit 10 to behind-the-ear unit 30.
Moreover, in one embodiment, at least one of the earlier mentioned one or more ends
of connector 20 that may be detachably physically coupled to unit 10 or unit 30 may
be detachably communicatively coupled to unit 10 or unit 30.
[0081] In some embodiments, connector 20 includes hollow tubing 21 (preferably insulated
and made from plastic). In one of these embodiments, wire cable(s) 22 is disposed
within tubing 21. Preferably, only two or three wire cables are disposed within tubing
21. However, a greater or fewer number of wires can be disposed therein. For example,
the processing circuitry of module 33 may require a greater or lesser number of wire
cables within tubing 21. In an alternative embodiment, unit 10 and unit 30 are communicatively
coupled via a wireless connection, and thus, wire cable(s) 22 are not present. Furthermore,
as discussed earlier, in some embodiments, speaker 13, speaker fastener 14 and/or
module fastener 31 are part of connector 20.
[0082] Preferably, wire cable(s) 22 is communicatively (e.g., electrically) and/or physically
coupled to speaker fastener 14 (e.g., coupling 23 of FIGURE 1). The communicative
and/or physical coupling between wire cable(s) 22 and speaker fastener 14 may be fixed,
such as through hard-wiring. On the other hand, the coupling between wire cable(s)
22 and speaker fastener 14 may be detachable, e.g., through a detachable electrical
prong and hole arrangement.
[0083] Similarly, in one embodiment, wire cable(s) 22 is communicatively (e.g., electrically)
and/or physically coupled to module fastener 31 (e.g., coupling 24 of FIGURE 1). As
was the case with respect to speaker fastener 14, the communicative coupling between
wire cable(s) 22 and module fastener 31 may be fixed, such as through hard-wiring.
On the other hand, the communicative coupling between wire cable(s) 22 and module
fastener 31 may be detachable, e.g., through a detachable prong and hole arrangement.
[0084] In a preferred embodiment, connector 20 is of sufficient length to physically and/or
communicatively couple unit 30 to unit 10 when unit 30 is placed behind-the-ear of
a user and unit 10 is placed within the ear canal of a user so far as to touch the
bony portion of the ear canal. Moreover, when in use, preferably a first portion of
connector 20 is at least within the ear canal of the user. In some embodiments, e.g.,
when speaker 13 and/or speaker fastener 14 are part of connector 20, similar to the
manner discussed earlier with respect to unit 10, a portion of connector 20 is inserted
within and coupled to ear mold 11 of unit 10, e.g., through receiving member 12 (e.g.,
the assembled portion of device 40 depicted in FIGURE 2). Accordingly, in one embodiment,
a portion of connector 20, when in use, is part of an assembly that includes ear mold
11 and receiving member 12 of unit 10 that may be inserted so deep within the user's
ear canal as to touch the bony portion. Furthermore, when in use, preferably a second
portion of connector 20 is located behind the ear of the user (to include embodiments
where fastener 31 is not part of connector 20). In addition, preferably, the dimensions
of connector 20 are such that those portions of connector 20 not in the bony portion
or outer portion of the user's ear canal or behind the user's ear are taut against
the head of the user when device 40 is in use. In a preferred embodiment, the dimensions
of connector 20 are such that connector 20 is indiscernible to one casually viewing
the user when device 40 is in use.
[0085] Accordingly, completely-in-canal unit 10, connector 20, and behind-the-ear unit 30
may be physically and/or communicatively coupled together. In a preferred embodiment,
one or more of these couplings are detachable, such that, unit 10 and/or unit 30 can
be easily attached to and detached from connector 20 or vice versa, thus allowing
for convenient and easy assembly of auditory device 40, as well as relatively easy
replacement of any inoperative, defective, or otherwise unsatisfactory parts.
[0086] For instance, if connector 20 is deficient for some reason (e.g., a wire has failed
and/or connector 20 is too long and thus is cosmetically undesirable when the device
is in use), in one embodiment, the end of connector 20 coupled to unit 10 may be easily
detached (at least relatively speaking) from unit 10 by pulling the pieces apart (e.g.,
embodiments where connector 20 is detachably coupled to fastener 14, such as through
a hole and prong arrangement). Furthermore, in one embodiment, connector 20 may be
detached from unit 30 by pulling apart a detachable coupling between connector 20
and fastener 31 (e.g., when connector 21 and fastener 31 are coupled via a hole and
prong arrangement). In addition, an acceptable replacement connector may be selected.
Afterwards, in one embodiment, one end of the replacement connector may be coupled
to unit 10 by pushing fastener 14 and connector 20 together (e.g., a hole and prong
coupling), while a second end of the replacement connector may be coupled to unit
30 by pushing connector 20 and fastener 31 together (e.g., a hole and prong coupling
as well).
[0087] In some of the embodiments where speaker fastener 14 and/or module fastener 31 are
part of connector 20, connector 20 may be separated from ear mold 11 by depressing
a portion(s) of ear mold 11, receiving member 12, and/or fastener 14 and pulling fastener
14 from ear mold 11. In embodiments where speaker 13 is part of unit 10, fastener
14 may then be removed from unit 10 by pulling speaker 13 from fastener 14 (e.g.,
where fastener 14 and speaker 13 are coupled via a hole and prong arrangement). In
addition, in one embodiment, connector 20 may be separated from unit 30 by depressing
a portion(s) of fastener 31 and pulling fastener 31 from module 33. A new connector
may than be coupled (or the previous connector re-coupled) to unit 10 and/or unit
30 via one of the earlier described means for coupling fastener 14 to speaker 13 and
ear mold 11 and/or coupling fastener 31 to shuttle 33.
[0088] Similar to earlier discussions, in a preferred embodiment, the coupling between connector
20 and unit 10 is of sufficient strength such that unit 10 may be removed from within
the user's ear canal by pulling on connector 20. Moreover, in addition to or in lieu
of the above, in one embodiment, the coupling between connector 20 and unit 30 is
of sufficient strength such that unit 30 may be removed from behind the user's ear
by pulling on connector 20.
[0089] The size, shape, dimensions, etc., of connector 20 shown in FIGURE 1 are by way of
example only, as connector 20 can be of numerous sizes and shapes. In addition, elements
not depicted in FIGURE 1 may be included in connector 20. For example, in one embodiment
where speaker fastener 14 is part of connector 20, fastener 14 includes a retrieval
line for aiding a user in retrieving and/or inserting unit 10 into and out of the
user's ear canal. On the other hand, elements included in FIGURE 1 may be absent from
connector 20. Moreover, as mentioned, in at least one embodiment, connector 20 includes
speaker 13, fastener 14, and/or fastener 31.
[0090] FIGURE 9 depicts the embodiment of earpiece auditory device 40 shown in FIGURE 1
after the embodiment of device 40 has been assembled. Again, it will be appreciated
that the elements of device 40, as well as the arrangement of these elements, depicted
in 9 are by way of example only, for earpiece auditory device 40 may have several
configurations.
[0091] As a non-limiting example of such, FIGURES 10A, 10B, and 10C depict an alternative
embodiment of earpiece auditory device 40. In the embodiment of FIGURE 10A, similar
to the embodiment illustrated in FIGURE 1, earpiece auditory device 40 includes ear
mold 11, speaker receiving member 12, speaker 13 and speaker fastener 14. The earlier
discussions regarding ear mold 11, speaker receiving member 12, speaker 13 and speaker
fastener 14 apply equally as well to the embodiments of these elements present in
the embodiment of FIGURE 10A.
[0092] Also similar to the embodiment of FIGURE 1, device 40 also includes connector 20.
The above discussions regarding connector 20 also apply equally as well to connector
20 of FIGURE 10A. However, in the embodiment of FIGURE 10A, rather than potentially
including module fastener 31, connector 20 instead includes module fastener 100. Preferably,
module fastener 100 is operable to plug into connector receptacle 120 of processing
module 110 (as shown in FIGURES 10B and 10C).
[0093] Processing module 110 of FIGURES 10A, 10B, and 10C is similar to module 30, one difference
being that module 110 does not potentially include fastener 31. Otherwise, the above
discussions regarding module 30 apply equally as well to module 110.
[0094] Exemplary embodiments of at least a portion of the interior of module 110 are depicted
in FIGURES 11A and 11B. In the embodiment of FIGURE 11A, at least a portion of the
interior of module 110 includes a connector 160 (which preferably includes receptacle
120) for communicatively (e.g., electrically) and/or physically coupling module 110
to connector 20. In one embodiment, such a coupling(s) is detachable. Moreover, in
one embodiment, connector 160 is communicatively coupled to processing circuitry 140
(similar to earlier discussions, such processing circuitry may include sound processing
circuitry). In the illustrate embodiment, processing circuitry 140 is communicatively
coupled to microphone 130. In one embodiment, module 110 includes power source 150
(e.g., a battery).
[0095] Another exemplary embodiment of at least of a portion of the interior of module 110
is depicted in FIGURE 11B. Similar to FIGURE 11A, in the embodiment of FIGURE 11B,
the internal circuitry of module 110 includes connector 160 for communicatively (e.g.,
electrically) and/or physically coupling module 110 to connector 20. Also similar
to FIGURE 11A, in at least one embodiment, connector 160 is communcatively coupled
to processing circuitry 140 (similar to earlier discussions, such processing circuitry
may include sound processing circuitry). However, rather than being coupled to a microphone
as in FIGURE 11A, circuitry 140 is communicatively coupled to communications link
170. In the illustrated embodiment, module 110 also includes power source 150 (e.g.,
a battery).
[0096] Moreover, in one embodiment, at least a portion of the interior of module 110 resembles
the embodiment of FIGURE 11A with the addition of communications link 170 communicatively
coupled to processing circuitry 140.
[0097] In various embodiments, the earpiece auditory device of the present invention overcomes
the difficulties associated with prior earpiece auditory devices.
[0098] With regards to the problem of bulkiness and noticeability of earlier prior art auditory
devices, as previously mentioned, when in use, preferably completely-in-canal unit
10 is positioned so deep inside the ear canal of a user as to touch the bony portion
of the user's hearing canal. Accordingly, the unit is indiscernible to an observer.
In addition, in one embodiment, fastener 31 and module 33 are of a particular size
and shape such that, when placed behind the cartilage of the ear of a user, fastener
31 and module 33 are made invisible to an observer by the cartilage of the user's
ear. Also as mentioned, in one embodiment, the dimensions of connector 20 are such
that those portions of connector 20 not in the bony or outer portion of the user's
ear canal or behind the user's ear when device 40 is in use are taut against the head
of the user. Furthermore, in at least some of these embodiments, the dimensions of
connector 20 are such that connector 20 is indiscernible to one casually viewing the
user. Accordingly, in one embodiment, when device 40 is in use, its presence will
be indiscernible to the casual observer. Therefore, the earlier problems of bulkiness
and noticeability are reduced, if not alleviated, by the present invention.
[0099] With respect to the occlusion dilemma discussed earlier, because, in one embodiment,
completely-in-canal unit 10 is inserted so deep in the user's ear canal as to touch
the bony portion, the device does not cause the patient to experience the occlusion
effect. Therefore, embodiments of the present invention reduce the occlusion effect
without having to resort to vents, open mold configurations, etc. (although vents,
open molds, etc., may still be used for other purposes).
[0100] Similarly, with regards to the feedback problems occurring with some prior art auditory
devices (e.g., conventional hearing aids), in some embodiments, the microphone(s)
of device 40 (or equivalent device(s)) is mechanically isolated from the speaker(s)
of device 40. Therefore, electroacoustic feedback is, at the very least, greatly reduced.
[0101] Accordingly, various embodiments of the present invention enable a user to have the
benefit of a high-gain earpiece auditory device without the accompanying detriment
of suffering from the occlusion effect.
[0102] In addition to the above, in some embodiments, at least portions of the earpiece
auditory device are protected from one or more undesirable external elements (such
as moisture, cerumen, dirt, etc.) to which certain prior art devices are susceptible.
[0103] Moreover, in one embodiment, the couplings of the earpiece auditory device do not
require significant space in order to be implemented. Accordingly, significant device
space and/or other limited space in around the user's ear need not be taken up by
the couplings of embodiments of the present invention.
[0104] Furthermore, in one embodiment, the coupling(s) between the connector, the behind
the ear component, and the completely-in-canal component is of sufficient strength
that the completely-in-canal unit and behind-the-ear unit may be removed from the
user's ear by pulling on the connector without any undesirable separation of the components.
[0105] Moreover, as mentioned earlier, in a preferred embodiment, one or more portions of
the earpiece auditory device may be assembled with relative ease. As a result, in
one embodiment, an earpiece auditory device in accordance with the present invention
may be mass produced, while at the same time provide a tailored fit to one or more
users.
[0106] For example, rather than waiting until a particular customer has been fitted, tested,
etc., to manufacture an auditory device for that customer, the manufacturer(s) of
at least one embodiment of an earpiece auditory device of the present invention may
instead make available one or more mass produced components (and/or elements thereof)
of an embodiment(s) of the earpiece auditory device. The user, or other individual,
may then select from the above described components, elements, etc,. those components,
elements, etc., that provide the fit and functional capabilities desired by the user.
The user, or other individual, may then assemble the device himself/herself
[0107] To illustrate, the manufacturer(s) may make available a plurality of behind-the-ear
units from which a behind-the-ear unit operable to facilitate a particular user's
intended use for an earpiece auditory device may be selected. This plurality of behind-the-ear
units may include units of different types, shapes, sizes (e.g., so that a user may
select a behind-the-ear unit that is of a particular size so that the unit is made
invisible by the user's ear when placed behind the user's ear), functional capabilities
(e.g., two or more of the behind-the-ear units may have different sound processing
circuitry), etc. However, two or more of the behind-the-ear units may be of the same
type, shape, size, functional capability, etc.
[0108] The manufacturer(s) preferably may also make available a plurality of one or more
elements of a completely-in-canal unit (e.g., a plurality of ear molds and/or a plurality
of speakers) and/or a plurality of completely-in-canal units, from which a user, or
other individual, may select at least one of the elements to be included in the completely-in-canal
unit of the user's device. Similar to the earlier discussion, the plurality of one
or more elements includes elements of different, types, shapes, sizes (e.g., multiple
pre-made sizes of ear molds), functional capabilities (e.g., the plurality of one
or more elements may include two or more speakers having different speaker performance
characteristics), etc. However, similar to the above discussion, in one embodiment,
two or more of the earlier mentioned plurality may be of the same type, shape, size,
functional capability, etc. In one embodiment, the earlier mentioned plurality may
include universal-fit tips, such as the foam tips, slips, boots, etc., described earlier,
to provide a desired fit for the user. Furthermore, custom-made ear molds may be included
as well.
[0109] In addition, in one embodiment, the manufacturer(s) may also make available a plurality
of connectors from which a user may select a connector to couple (physically and/or
communicatively) the selected behind-the-ear unit to a selected completely-in-canal
component or the completely-in-canal unit that includes the one or more selected elements.
In a preferred embodiment, at least one of the connectors includes at least one end
operable to detachably couple (physically and/or communicatively) the connector to
the selected behind-the-ear unit or completely-in-canal unit. Similar to the above
discussions, the plurality of connectors may be of different types, sizes (e.g., different
lengths), shapes, functional capabilities, etc. Moreover, two or more of the plurality
of connectors may be of the same type, size, shape, functional capability, etc. Preferably,
from the plurality of connectors, the user may select a connector of sufficient length
to couple the selected behind-the-ear component, when placed behind the ear of the
particular user, to the completely-in-canal unit, when placed inside the ear canal
of the particular user so deep as to touch the bony portion of the user's ear canal.
In another embodiment, preferably the user may select a connector of such dimensions
that when in use, those portions of the connector not in the bony or outer portion
of the user's ear canal or behind the user's ear are taut against the user's head.
[0110] The above, units, elements, etc., may be offered on an individual basis or in combination
with other elements, sizes, shapes, etc. (e.g., one packet may contain an ear mold
of a particular shape and size, while another packet may contain ear molds of various
types, shapes and sizes, while yet another packet may contain a particular length
of connector, and still another packet may contain a speaker and a connector already
coupled together).
[0111] As discussed earlier, the user, or other individual, may then assemble the selected
pieces together to form an earpiece auditory device fitting the user's ear structure,
as well as the user's intended use for the device. Accordingly, a distributor, dispenser,
or the user himself/herself, may make the initial assembly of the device, instead
of the manufacturer. In addition, in one embodiment, the distributor, dispenser, user,
etc., may tailor the device to fit the particular user's ear structure, as well as
the user's intended use for the device, by determining which combination of the pre-made
elements, sizes, shapes, etc., provides an optimal fit and operation for the particular
user.
[0112] Moreover, not only is assembly made more convenient, but disassembly, re-assembly,
repair, fitting, re-fitting, etc., is made convenient as well. Preferably, as a result,
the device may be repaired, etc., without the need to send the device to a repair
lab or return the device to the manufacturer, thereby saving the user from the earlier
described hassle associated with sending the device to the manufacturer. The same
holds true with refitting the device to a particular user if the initial fit was deficient
in some manner. In such instances, the distributor/dispenser and/or the user may simply
experiment with the various pre-made sizes until the optimal fit for the user is found.
[0113] Thus, preferably the present invention saves time and money for the user(s), the
manufacturer(s), and/or the distributor(s)/dispenser(s). However, the manufacturer
may still initially assemble the auditory devices and then make the other pre-made
components commercially available for repair or replacement purposes.
[0114] Another notable advantage is that, in various embodiments, the earpiece auditory
device discussed above may be used in a variety of applications. For example, embodiments
of the earpiece auditory device may be used in a manner similar to conventional hearing
aids.
[0115] In addition, embodiments of the earpiece auditory device may be used as earphones
(or similar device(s)) for such electronic devices as televisions, radios, CD players,
stereos, cell phones, computers (to include personal digital assistants and other
processor based devices). As mentioned, in one embodiment, the earpiece auditory device
may receive transmissions from and/or broadcast transmissions to a remote device(s)
by wired or wireless means (e.g., radio frequency (RF) means, optical means, magnetic
induction coil, etc.).
[0116] Moreover, in at least some embodiment(s), the earpiece auditory device may receive
and/or broadcast data or other transmissions (be it via wired or wireless means) to
a remote device (e.g., audio files, MP3 files, voice streams, video streams, Internet
broadcasts, audio e-mails, etc). The device may be complaint with the various transmission
formats, protocols (to include TCP/IP, Bluetooth, etc.), and interfaces necessary
to receive and/or process such transmissions.
[0117] Embodiments of the earpiece auditory device of the present invention may also be
used as monitors for recordings. For example, a musician, or other individual recording
sounds, may hear sounds as they are being processed by studio equipment through an
embodiment of the present inventions.
[0118] In addition, embodiments of the earpiece auditory device may be used as IFB devices,
e.g., for newscasters, whereby audio may be provided to the newscaster.
[0119] In addition to manipulating sound in the manner described above, embodiments of the
earpiece auditory device of the present invention may be used to decrease, muffle,
or eliminate certain sounds. For example, as discussed earlier, in at least one embodiment
the earpiece auditory device of the present invention may be used as an electronic
ear plug.
[0120] FIGURES 12A-12C illustrate potentially disposable link module 1220 integral with
speaker module 1212, in accordance with an alternative embodiment of the present invention.
FIGURES 13A-13C illustrate universal tip module 1330 detachably interconnectable with
speaker module 1212, in accordance with embodiments of the present invention. FIGURES
14A-14B illustrate the assembly of link module 1220 and universal tip module 1330
into behind-the-ear / completely-in-canal (BTE/CIC) earpiece auditory device embodiment
1440, including BTE processing module, for example processing module 110, in accordance
with embodiments of the present invention.
[0121] Link module 1220, similar to connector 20 of FIGURES 10A-10C, at its proximal end
is detachably coupled physically and communicatively to processing module 110 using,
for example, previously described module fastener 100, to construct alternative BTE/CIC
earpiece auditory device embodiment 1440. The physical size and shape of processing
module 110 are designed to fit discreetly and comfortably behind the user's ear. In
some embodiments, processing module 110 incorporates at least one user-operable switch
1450, which can control volume, change memory, and/or select the mode of operation
of processing circuitry internal to processing module 110, for example t-coil, directional
microphone, wireless communication, and the like. Embodiments of interior portions
of processing module 110 are described above in connection with FIGURES 11A-11B.
[0122] Similar to connector 20, link module 1220 includes flexible tubular portion 1222,
which physically and communicatively couples BTE processing module 110 with CIC unit
1410, functionally analogous with CIC unit 10, described above in connection with
FIGURE 1. Unlike connector 20, the distal end of link module 1220 is permanently attached
to speaker module 1212, which at least partially encases speaker 1540 (refer to FIGURE
15A). In some embodiments, one end of tubular portion 1222 is communicatively coupled
to speaker 1540, e.g., by wiring connections, and then encapsulated with speaker 1540
into the shell of speaker module 1212, e.g., using a plastic injection molding operation.
The tubing material of tubular portion is typically silicone, fluorocarbon (e.g.,
PTFE) or similar flexible plastic material, which is attached by gluing, laser welding,
or other suitable technique. Preferably speaker module 1212 is formed of a hard and
rigid plastic material.
[0123] In some embodiments, CIC unit 1410 includes a universal tip assembly, for example
universal tip assembly 1330, incorporating conventional soft umbrella tip 1320 slipped
on over the tubular neck of hollow sleeve 1310, as depicted in FIGURES 13A-13C. Sleeve
1310 is preferably made of a soft resilient urethane or silicone type polymer material.
Umbrella tip 1320 is made of a polymer material softer than that of sleeve 1310, preferably
a soft silicone or alternatively a polymer foam. Universal tips or ear molds, such
as umbrella tip 1320, are normally available in a range of sizes which are selectable
to fit any ear canal.
[0124] In one embodiment, speaker module 1212 and sleeve 1310 are configured to be releasably
latched together. Speaker module 1212 and sleeve 1310 have similarly shaped cross-sections,
such that speaker module 1212 is inserted into open end 1316 of sleeve 1310. Surfaces
of speaker module 1212 are appropriately tapered and/or radiused, such that they deform
and pry apart the walls of sleeve 1310. Rigid flange 1214 of speaker module 1212 slides
over and outwardly deflects resilient strap 1314 of sleeve 1310. After flange 1214
clears strap 1314, flange 1214 engages slot 1312 of sleeve 1310, where it is latched
securely into place by resilient strap 1314, which has elastically relaxed to its
undeflected shape and position. CIC unit 1410 incorporating universal tip assembly
1330 and speaker module 1212 can then be inserted within any user's ear canal. To
release sleeve 1310 from speaker module 1212, a user or dispenser pries strap 1314
outwardly using a suitable tool (e.g., thumbnail) until it clears flange 1214, and
then withdraws speaker module 1212 from open end 1316 of sleeve 1310 (e.g., by applying
moderate pulling force to tubular portion 1222 of link module 1220). Those skilled
in the art will recognize that other releasable latching schemes can be employed,
which fall within the scope and spirit of the present invention.
[0125] Advantageously, in embodiments of earpiece auditory device 1440, link module 1220
in its entirety including speaker module 1212 is dispenser replaceable by the professional
without needing to be returned to the factory. Optionally, universal tip assembly
1330, which is inexpensive, can be separately dispenser or user replaceable.
[0126] FIGURES 15A-15B depict a further embodiment of CIC/BTE earpiece auditory device 1440,
including link module 1520 incorporating custom ear mold 1510 fastened by a detachable
locking pin. FIGURES 15C-15F illustrate details of detachable locking pin assembly
embodiment 1550 used in link module embodiment 1520. Similar to link module 1220,
link module 1520 includes module fastener 100, tubular portion 1522 similar to tubular
portion 1222, and integrally attached speaker module 1212, which in the present embodiment
is encapsulated together with hollow straight tube 1512 aligned along the axis of
speaker 1540. Speaker module 1212 can be encapsulated into a variety of sizes and
shapes, but for commonality of manufacturing is depicted with the same size, shape,
and material as described in connection with FIGURES 12A-12C and 14A-14B.
[0127] Custom ear mold 1510 is made of a soft polymer material, for example an elastomer
or silicone in the 3-40 durometer range, and is individually shaped to fit exactly
within the ear canal of a particular user. In the present embodiment, custom ear mold
1510 is encapsulated around collar 1513, which contains a clearance hole dimensioned
to slide over the outer diameter of hollow straight tube 1512. Preferably custom ear
mold 1510 is fabricated using a form of rapid prototyping technology, for example
stereolithography (SLA). With this technology, the surface of user's ear canal or
an ear mold cast from the user's ear is optically scanned, and the scan data is used
to control a selective polymerization or material removal process to replicate exactly
the shape of the original scanned surface. In some implementations, the scan data
is digitized, electronically stored indefinitely, and/or manipulated or processed
as desired. In some versions a direct replica, e.g., custom ear mold 1510 is produced
from the scan data. In other versions a negative shell or mold of acrylic or other
suitable material is produced directly, from which custom ear mold 1510 is produced
indirectly by a casting process.
[0128] To assemble CIC module 1530 of link module 1520, custom ear mold 1510 containing
collar 1513, slides over hollow straight tube 1512 encapsulated into speaker module
1212, until custom ear mold 1510 seats against speaker module 1212. Hollow detachable
locking pin 1514 containing flange 1515 is inserted through the open end of collar
1513 and is forced into hollow straight tube 1512. Because the outside diameter of
flange 1515 is larger than the inside diameter of hollow straight tube 1512, detachable
locking pin 1514 makes an interference fit with hollow straight tube 1512, thereby
deforming the outer wall of hollow straight tube 1512 and locking custom ear mold
1510 onto speaker module 1212 through frictional force. CIC module 1530 containing
custom ear mold 1510 can then be inserted within the user's ear canal. To disassemble
CIC module 1530, detachable locking pin 1514 can be pried out of hollow straight tube
1512 using a suitable tool, for example a wedge, vise, or pliers. Detachable locking
pin 1514, collar 1513, and hollow straight tube 1512 are preferably made of a resilient
silicone or fluorocarbon (e.g., PTFE) type polymer material.
[0129] Alternatively, detachable locking pin assembly 1550 can be used to secure a conventional
universal soft umbrella tip, similar to umbrella tip 1320, onto speaker module 1212.
[0130] FIGURES 16A-16B depict an alternative earpiece auditory device, in accordance with
embodiments of the present invention, having a custom ear mold directly encapsulated
onto link module 1620. Similar to link module 1520 depicted in FIGURES 15A-15B, link
module 1620 incorporates module fastener 100, tubular portion 1522, and speaker module
1212 encasing speaker 1540. Custom ear mold 1610 similar to custom ear mold 1510 is
directly encapsulated around speaker module 1212. Orifice 1612 in the tip of custom
ear mold 1610 provides a sound conducting passage to speaker 1540. CIC module 1630
includes custom ear mold 1610 and speaker module 1212. The materials and fabrication
technology used in custom ear mold 1610 are substantially the same as those used in
custom ear mold 1510.
[0131] This nondetachable version is essentially a single-piece component that includes
speaker module 1212 all the way to custom ear mold 1610. Speaker 1540 is thus completely
encapsulated into a custom molded component, and accordingly would be disposable,
such that if speaker 1540 failed, rather than repairing that speaker, an entire exact
duplicate assembly can be recreated using the electronically stored scan data file
of that particular ear mold. Everything including entire link module 1620 and from
there downward would be replaced.
[0132] Detachability typically occurs between module fastener 100 at the proximal end of
link module 1620 and BTE processing module 110. In other words, the complete custom
version auditory device appears as a two-piece unit to the user or dispenser: just
the BTE processor 110 and link module 1620 including integral speaker module 1212
and custom ear mold 1610, versus the three-piece configuration of universal version
1440.
[0133] In some embodiments, the distal end of link module 1220 or 1620 could be detachable
from the speaker module and ear mold. However, it may be more cost effective and efficient
not to add the complexity and expense of the additional distal connector pins to couple
wires that go through that link to the speaker, but simply to make link module 1220
or 1620 disposable including integral speaker module 1212 and custom ear mold 1610.
[0134] In alternative embodiments, the proximal end of link module 1220 or 1620 could be
nondetachably integrated with BTE processing module 110, thereby eliminating detachable
module fastener 100, such that BTE/CIC earpiece auditory device 1440 can be manufactured
as a single-piece disposable unit.
