Technical Field
[0001] The invention relates to a hearing device.
Background of the Invention
[0002] Active noise cancelling technology (ANC) in hearing aids can provide a significant
increase in hearing performance compared to traditional hearing aid couplings and
receivers. The three main use cases, where an ANC hearing aid can provide significant
benefit, are:
- 1. Communication in noise: In a loud and challenging communication scene (e.g. restaurant),
ANC can reduce direct sound and occlusion sound at the same time and is therefore
able to make the hearing aid audible over the whole frequency range of interest (e.g.
100 Hz - 10 kHz) without adding any dominant disturbing occlusion effect.
- 2. Tune out: When listening to streamed audio in loud environments (e.g. airplane,
train), ANC can attenuate disturbing ambient noise much better compared to a traditional
hearing aid coupling without ANC. This results in better comfort in noise.
- 3. Sound quality: ANC requires a speaker with high output at low frequencies, which
means also that the perceived sound quality of streamed audio is increased compared
to traditional hearing aid receivers.
[0003] However, ANC typically requires a larger speaker and/or earpiece size compared to
traditional hearing aids. Bulky earpieces are typically less in demand, especially
if the device is intended to be worn the full day.
Summary of the Invention
[0004] It is an object of the present invention to provide a novel hearing device.
[0005] The object is achieved by a hearing device according to claim 1.
[0006] Exemplary embodiments of the invention are given in the dependent claims.
[0007] According to the invention, a hearing device comprises a an RIC assembly, also referred
to as a receiver-in-the-canal assembly or earpiece part, configured to be worn in
an ear canal, the RIC assembly having a shell containing a receiver, wherein the RIC
assembly comprises multiple electrical connection pads, the hearing device further
comprising an ANC module, also referred to as an active noise cancelling module, configured
to be releasably coupled to the RIC assembly and to perform active noise cancelling,
the ANC module having electrical connectors configured for electrically contacting
the electrical connection pads.
[0008] In an embodiment, the RIC assembly comprises one or more acoustic ANC canals configured
to lead sound from the ANC module into the ear canal bypassing the receiver when the
RIC assembly is worn in the ear canal and when the ANC module is coupled to the RIC
assembly.
[0009] In an embodiment, the RIC assembly further comprises a cup-shaped receptacle at a
lateral end of the shell, the receptacle configured to receive the ANC module or a
portion thereof.
[0010] In an embodiment, the ANC module is configured to be retained on the RIC assembly
by magnetic force.
[0011] In an embodiment, the magnetic force is provided by one or more magnets arranged
on the RIC assembly and/or on the ANC module. The other one of the RIC assembly and
the ANC module may also have one or magnets or one or more elements made of a magnetisable
material.
[0012] In an embodiment, the one or more magnets are arranged in or on the receptacle.
[0013] In an embodiment, the ANC module is shaped to fit to the lateral end of the RIC assembly.
[0014] In an embodiment, the ANC module is shaped to match the receptacle.
[0015] In an embodiment, the receptacle has a recess and the ANC module has a locator rib
matching the recess or vice versa, so that the ANC module couples to the RIC assembly
in a defined position such that the electrical connectors of the ANC module connect
to the electrical connection pads of the RIC assembly.
[0016] In an embodiment, the hearing device further comprises a BTE assembly, also referred
to as a behind the ear assembly, coupled or configured to be coupled to the RIC assembly
by a cable.
[0017] In an embodiment, the RIC assembly and/or the BTE assembly are/is configured to automatically
detect and activate the ANC module once the electrical connectors contact the electrical
connection pads.
[0018] In an embodiment, the ANC module further includes a speaker and two microphones,
one of the microphones facing toward the RIC assembly and another one of the microphones
facing away from the RIC assembly when the ANC module is coupled to the RIC assembly.
[0019] In an alternative embodiment, the inwards facing microphone could be arranged in
the RIC assembly. This would be beneficial from an acoustic point of view; however,
more electrical connection pads and electrical connectors may be required.
[0020] In an embodiment, circuitry configured to perform the active noise cancelling is
arranged in one of the ANC module, the RIC assembly and the BTE assembly or is distributed
over at least two of these components.
[0021] In an embodiment, the ANC module is powered through the RIC assembly from a battery
located in the RIC assembly or in the BTE assembly.
[0022] In an embodiment, the RIC assembly further comprises a dome at a medial end of the
shell, the dome having an open coupling.
[0023] The solution according to the invention is a hearing aid system, which can be situationally
upgraded with active noise cancelling technology, resulting in better hearing performance
when needed and only reduces discreteness in these specific situations. For the rest
of the day, the hearing aid system may remain discrete and nicely hidden.
[0024] Further scope of applicability of the present invention will become apparent from
the detailed description given hereinafter. However, it should be understood that
the detailed description and specific examples, while indicating preferred embodiments
of the invention, are given by way of illustration only, since various changes and
modifications within the spirit and scope of the invention will become apparent to

Detailed Description of Preferred Embodiments
[0027] Figure 1 is a schematic view of a hearing device 1, comprising an RIC assembly 2, also referred
to as a receiver-in-the-canal assembly 2 or earpiece part, worn in an ear canal of
an ear 3 of a user, and a BTE assembly 4, also referred to as a behind the ear assembly
4, coupled to the RIC assembly 2 by a cable 6.
Figures 2 and 3 are schematic views of the RIC assembly 2 which is configured as a small device having
a receiver or speaker (not shown) in a shell 7 and a dome 8 at a medial end of the
shell 7 with a very open coupling, which means it cannot deliver much performance
in challenging situations, but it can sufficiently address a mild to moderate hearing
loss in most situations during the day.
[0028] The RIC assembly 2 comprises multiple electrical connection pads 9 at a lateral end
of the shell 7, e.g. in a cup-shaped receptacle 10 which may be arranged at the lateral
end. The connection pads 9 may be located on a surface of the shell 7 or receptacle
10 or they may be recessed therein.
[0029] Figure 4 is a schematic view of the hearing device 1 of figure 1 with an ANC module 11, also
referred to as an active noise cancelling module 11, being added to the RIC assembly
2. When a situational performance upgrade is needed, the user can simply add the ANC
module 11 to the RIC assembly 2. The ANC module 11 includes a more powerful speaker
20 and two microphones 21.1, 21.2. One of the microphones 21.2 may face inwards, i.e.
toward the RIC assembly 2 when the ANC module 11 is coupled to the RIC assembly 2.
Another one of the microphones 21.1 may face outwards, i.e. away from the RIC assembly
2 when the ANC module 11 is coupled to the RIC assembly 2. This configuration provides
a so-called hybrid ANC (combination of feedback-ANC and feedforward-ANC). The ANC
module 11 is powered through the RIC assembly 2 from a battery which may be located
in the BTE assembly 4. Therefore, the ANC module 11 does not require a separate battery.
The ANC module 11 might include separate circuitry in order to perform the ANC processing.
[0030] Figure 5 is a schematic view of the hearing device 1 of figure 1 with the ANC module 11 coupled
to the RIC assembly 2.
[0031] Since the RIC assembly 2 is designed to be acoustically very open, the sound of the
ANC module 11 can easily reach the ear canal through the openings of the RIC assembly
2.
[0032] Figures 6, 7 and 8 show different views of the RIC assembly 2 with the dome 8 removed from a sound port
15 of the RIC assembly 2 for clarity. The open coupling of the RIC assembly 2 is achieved
by acoustic ANC canals 12 bypassing the receiver 13 and the related one or more acoustic
receiver canals 18.
[0033] Figures 9 and 10 show different views of the RIC assembly 2 with the dome 8 attached to the sound
port 15 of the RIC assembly 2.
[0034] In an exemplary embodiment, magnetic force may be used to connect the RIC assembly
2 with the ANC module 11. The hearing device 1 may be configured to automatically
detect the ANC module 11 and activate the ANC mode, once the ANC module 11 is connected
to the RIC assembly 2 and electrical connectors (not shown) of the ANC module 11 connect
the electrical connection pads 9 of the RIC assembly 2. The magnetic force may be
generated by one or more magnets 14 arranged on the RIC assembly 2 and/or on the ANC
module 11. In an exemplary embodiment, the magnets 14 may be arranged at the lateral
end of the RIC assembly 2, e.g. in or on the receptacle 10.
[0035] Figure 11 is a schematic view of the RIC assembly 2 with the ANC module 11.
[0036] The ANC module 11 may be shaped to fit to the lateral end of the RIC assembly 2.
In particular, the ANC module 11 may be shaped to match the receptacle 10. In an exemplary
embodiment, the receptacle 10 may have a recess 16 and the ANC module 11 may have
a locator rib 17 matching the recess 16 so that the ANC module 11 couples to the RI
device 2 in a defined position to ensure that the electrical connectors of the ANC
module 11 connect the electrical connection pads 9 of the RIC assembly 2.
[0037] Figure 12 is a schematic view of the ANC module 11 with the electrical connectors 19 configured
for contacting the electrical connection pads 9. If the electrical connection pads
9 are recessed in the shell 7 or receptacle 10, the electrical connectors 19 may be
configured to protrude sufficiently into the respective recesses to contact the electrical
connection pads 9.
[0038] The proposed solution may be experienced by a user similar to putting an earbud/hearable
into the ear. With the proposed solution, the components that need to be handled when
removing the hearing aid would only be the RIC assembly 2 and the ANC module 11, which
may be nicely handled with two hands.
