Field of disclosure
[0001] The present disclosure relates to a hearing aid provided with a light indicator.
Background
[0002] Hearing aids are continuously developed in order to reduce their physical size. Accordingly,
attempts are made to make modern behind-the-ear hearing aids as small as possible,
so they can fit almost "invisible" behind the user's ear.
[0003] One possible way to reduce the size of a hearing aid includes a reduction of the
number of parts to a minimum and optimise their position inside the device. In the
paediatric and geriatric segment, it is required to have a light indicator on the
hearing aid in order to provide a visual feedback to the user. A light indicator is
typically arranged at the back side of the hearing aid, between the microphones and
a push button. In this position the light indicator will be clearly visible for the
user and the people near the user, when the hearing aid is placed on the ear of the
user.
[0004] A typical light indicator in a hearing aid includes a light guide part, that transmits
the light illuminated from a light emitting diode (LED) on a printed circuit board
(PCB) to the outside of the device for making the light indicator visible for the
user. This solution is associated with several disadvantages:
[0005] A separate light guide part requires space in a crowded area inside the hearing aid.
Accordingly, this solution is not suitable for achieving the object of reducing the
physical size of the hearing aid.
[0006] Moreover, the small light guide part is difficult to handle in the production process.
In addition, fixation of the light guide part in the top shell of the hearing aid
is challenging.
[0007] Accordingly, it would be advantageous to have a more compact hearing aid having a
light source.
Summary of the disclosure
[0008] Preferred embodiments of the present disclosure can be achieved by a hearing aid
as described in the present disclosure. Other advantageous embodiments are defined
e.g. in the dependent sub claims, explained in the following description and illustrated
in the accompanying drawings.
[0009] According to an aspect of the disclosure, the hearing aid is a hearing aid having
a housing and a light source for emitting light, wherein the light source is arranged
below a structure that comprises a transparent section and a surrounding opaque section,
wherein the light source is arranged in a position that allows for transmission of
light through the transparent section of the structure.
[0010] Hereby, the hearing aid can be produced in a compact manner with a reduced number
of parts.
[0011] The housing of the hearing aid may be referred to as a shell. It may have any suitable
geometrical shape. The structure below which the light source is arranged may be a
plane structure, an arced structure or a combination thereof. The light source may
be any suitable type of light source including a LED.
[0012] According to another aspect of the disclosure, the structure is a one-piece body.
[0013] Hereby it is possible to reduce the number of components. Moreover, a more simple
manufacturing process and assembling process can be applied.
[0014] According to yet another aspect of the disclosure, the one-piece body constitutes
part of the periphery of the hearing aid.
[0015] Hereby, it is possible to provide the desired light signal to the user and the people
in the proximity of the user.
[0016] It may be an advantage that the light source is arranged in a short distance from
the periphery of the hearing aid (e.g. integrated in the housing or shell of the hearing
aid).
[0017] According to a further aspect of the disclosure, the one-piece body is a button.
[0018] Hereby, it is possible to arrange the light source in an area that is already used
for the button. Accordingly, it is possible to reduce the size of the hearing aid
since no separate space is needed for the light source itself.
[0019] The button may preferably be a push button.
[0020] According to another aspect of the disclosure, the light source is integrated in
the button.
[0021] Hereby, it is possible to produce a hearing aid that comprises fewer (a lower number
of) components than the prior art hearing aids. Consequently, it is possible to reduce
the size of the hearing aid.
[0022] According to yet another aspect of the disclosure, the hearing aid comprises two
switches and the light source is arranged between the two switches.
[0023] Hereby, the light source can be provided in a position, in which the light can be
easily reached by the user of the hearing aid and the people surrounding the user.
[0024] According to a further aspect of the disclosure, the hearing aid comprises two tactile
switches and the light source is arranged between the two tactile switches.
[0025] According to yet another aspect of the disclosure, the hearing aid comprises a button
provided with two switches and the light source is arranged between the two switches.
[0026] According to another aspect of the disclosure, the hearing aid comprises a button
having two tactile switches and the light source is arranged between the two tactile
switches.
[0027] Thus, the light source can be integrated in a prior art press button.
[0028] According to yet another aspect of the disclosure, the one-piece body is the housing
of the hearing aid.
[0029] Hereby, the light source can be integrated in the housing of the hearing aid. This
solution provides large design freedom.
[0030] According to an aspect of the disclosure, the opaque section comprises a painted
structure or surface.
[0031] The opaque section may be an injection moulded plastic component made in a transparent
material that is painted. Accordingly, a transparent section can be provided by removing
the paint in the desired area.
[0032] According to a further aspect of the disclosure, the transparent section is a painted
structure that has received a surface treatment. The surface treatment may be any
suitable type of surface treatment including laser treatment and mechanical surface
treatments.
[0033] According to an even further aspect of the disclosure, the surface treatment is a
laser treatment. Hereby, a well-defined area can be treated and a high precision can
be achieved.
[0034] According to a further aspect of the disclosure, the light source is a light emitting
diode (LED).
[0035] According to another aspect of the disclosure, the one-piece body is a moulded structure
that is painted. The moulded structure may be moulded by means of injection moulding
(e.g. an injection moulded plastic component).
[0036] According to yet another aspect of the disclosure, the hearing aid is a behind-the-ear
(BTE) hearing aid.
[0037] According to a further aspect of the disclosure, the one-piece body is provided with
an indentation. The indentation may be configured to converge or diverge light like
an optical lens.
[0038] According to another aspect of the disclosure, the one-piece body is provided with
an indentation provided in the transparent section.
[0039] According to a further aspect of the disclosure, the indentation is provided in the
central portion of the button.
[0040] Hereby, it is possible to provide a light signal that is easy to see for the user
and the people in the proximity of the user of the hearing aid.
[0041] According to another aspect of the disclosure, the thickness of the transparent section
equals the thickness opaque section.
[0042] Hereby, it is possible to ease the production of the structure, below which the light
source is arranged, in an easy manner.
[0043] According to a further aspect of the disclosure, the thickness of the transparent
section is smaller than the thickness opaque section. According to another aspect
of the disclosure, the thickness of the transparent section is larger than the thickness
of the opaque section.

Detailed description of the disclosure
[0045] A hearing aid is adapted to improve or augment a user's hearing capability by receiving
an acoustic signal from a user's surroundings, generating a corresponding audio signal,
possibly modifying the audio signal and providing the possibly modified audio signal
as an audible signal to at least one of the user's ears. The "hearing aid" may further
refer to a device adapted to receive an audio signal electronically, possibly modifying
the audio signal and providing the possibly modified audio signal as an audible signal
to at least one of the user's ears. Such audible signals may be provided in the form
of an acoustic signal radiated into the user's outer ear.
[0046] The hearing aid is adapted to be worn in any known way. This may include i) arranging
a unit of the hearing aid behind the ear with a tube leading air-borne acoustic signals
into the ear canal or with a receiver/ loudspeaker arranged close to or in the ear
canal such as in a behind-the-ear type hearing aid, and/ or ii) arranging the hearing
aid entirely or partly in the pinna and/ or in the ear canal of the user such as in
an in-the-ear type hearing aid or in-the-canal/ completely-in-canal type hearing aid,
or iii) arranging a unit of the hearing aid attached to a fixture implanted into the
skull bone such as in bone-anchored hearing aids or cochlear implants, or iv) arranging
a unit of the hearing aid as an entirely or partly implanted unit such as in bone-anchored
hearing aids or cochlear implant.
[0047] In general, a hearing aid includes i) an input unit such as a microphone for receiving
an acoustic signal from a user's surroundings and providing a corresponding input
audio signal, and/or ii) a receiving unit for electronically receiving an input audio
signal. The hearing aid further includes a signal processing unit for processing the
input audio signal and an output unit for providing an audible signal to the user
in dependence on the processed audio signal.
[0048] The input unit may include multiple input microphones, e.g. for providing direction-dependent
audio signal processing. Such a directional microphone system is adapted to enhance
a target acoustic source among a multitude of acoustic sources in the user's environment.
In one aspect, the directional system is adapted to detect (such as adaptively detect)
from which direction a particular part of the microphone signal originates. This may
be achieved by using conventionally known methods. The signal processing unit may
include an amplifier that is adapted to apply a frequency dependent gain to the input
audio signal. The signal processing unit may further be adapted to provide other relevant
functionality such as compression, noise reduction, etc. The output unit may include
an output transducer such as a loudspeaker/receiver for providing an air-borne acoustic
signal transcutaneously or percutaneously to the skull bone or a vibrator for providing
a structure-borne or liquid-borne acoustic signal. In some hearing aids, the output
unit may include one or more output electrodes for providing the electric signals
such as in a cochlear implant.
