Definitions
- the present invention relates to a hearing aid comprising a housing with a receiver/loudspeaker, and a filter, e.g. a cerumen filter, where the housing comprises an outer surface and an internal cavity adapted for containing the receiver/loudspeaker and where the housing further comprises a filter socket wherein the filter is releasably mounted, and where the filter socket is adapted for providing a sound channel extending through the filter between the outer surface and the receiver
- Hearing aids of the above mentioned kind are known in a lot of different embodiments, where the filter is mostly used as a wax guard with the primary purpose of avoiding ear wax from migrating into the receiver.
- ITE hearing aids with optimal sound quality and performance on the one hand, and on the other hand providing a hearing aid being as discrete as possible in the ear of the user.
- the purpose of the present invention is therefore to provide a hearing aid where especially the receiver and the filter socket is easy to dismantle for servicing or exchanging than what is the case with the prior hearing aids.
- the filter comprises a filter holder, and a filter unit, and where the filter holder and the filter unit are adapted for releasably mounting of the filter unit in the filter holder, and the filter holder is attached in the filter socket.
- the receiver/loudspeaker comprises a receiver housing having a first substantially plane side face with a sound opening
- the filter holder comprises a substantially plane bottom plate
- the filter holder is fastened to the receiver housing, so that the substantially plane bottom plate of the filter holder abuts the substantially plane side face of the receiver housing, and so that the sound opening is aligned with the first opening.
- the substantially plane bottom plate may in a further preferred embodiment be fastened to the first substantially plane side face of the receiver housing, so that the receiver and filter holder can be mounted or dismantled as a unit.
- the filter holder may preferably be permanently fastened to the receiver housing by gluing, soldering or welding, and the filter holder releasably attached to the housing with a press fit, a frictional fit, or by means of heat releasable glue.
- the hearing aid further comprises a signal processor arranged in the internal cavity of the housing, and being adapted for providing an audio signal to the receiver/loudspeaker via a set of electrical wires extending from the signal processor and to the receiver, and where the length of the electrical wires are so long that the receiver can be pulled out of the internal cavity through the filter socket, without the need of dismantling or stretching the electrical wires.
- a signal processor arranged in the internal cavity of the housing, and being adapted for providing an audio signal to the receiver/loudspeaker via a set of electrical wires extending from the signal processor and to the receiver, and where the length of the electrical wires are so long that the receiver can be pulled out of the internal cavity through the filter socket, without the need of dismantling or stretching the electrical wires.
- the receiver housing extends within a substantially uniform rectangular cross section in all planes being parallel to the first substantially plane side face, and the filter holder has a cylindrical outer surface defining an outer diameter, where the diagonal dimension of the substantially uniform cross section of the receiver housing is smaller than the outer diameter of the filter holder.
- Fig. 1 and 4 are principle drawings showing a cross section through hearing aid according to different embodiments of the invention.
- These hearing aids are both of the ITE (in the ear) type being adapted for being positioned completely in the ear of the user, but it will be apparent to the skilled person that the invention will also be applicable to other types of hearing aids being only partly positioned in the ear of the user.
- the hearing aids shown in figure 1 and 4 has a hearing aid housing 1 being closed at one end by a face plate 2, which will normally be the only visible part of the hearing aid, when the hearing aid is positioned in the ear of a user. Thereby the hearing aid housing 1 and the face plate 2 encloses an internal cavity 8.
- hearing aids of the ITE type all functional devices, such as electronics 3, batteries (not shown), wiring 4, a microphone (not shown), a receiver 5 and a cerumen filter holder 6 necessary for the function of the hearing aid have to be positioned in the narrow space provided by the internal cavity 8 in the hearing aid housing 1, and therefore it is important to have a high degree of freedom with respect to positioning each device in an optimal position in order to optimally utilize the space in the hearing aid housing 1.
- fig. 1 shows the filter holder without a filter unit mounted therein
- fig. 4 shows that a filter unit 11 is mounted in the filter holder 6.
- the hearing aid housing 1 further comprises e.g. a pressure equalizing channel 7 extending from the internal cavity 8 and to the outer surface 9 on the hearing aid housing 1.
- This pressure equalizing channel 7 must be arranged so that it is able to equalize pressure differences between the faceplate 2 on the outside of the hearing aid and the closed space in the ear of the user carrying the hearing aid, and thereby further reducing the freedom to position the functional devices in the internal cavity 8 of the hearing aid housing 1.
- a cerumen filter socket 13 is arranged in the end of the hearing aid housing facing the inside of the ear of the user, and the filter holder 6 is mounted in the filter socket 13, having a sound channel 10 extending between the filter holder 6 and the receiver 5.
- the filter holder 6 shown in the figures may e.g. be made from a plastic material, e.g. by injection moulding, or by deep drawing a sheet of metal to the shape shown in figure 1, 2 and 3 .
- the filter holder 6 is fixed to the plane side face 12 of the receiver 5 by welding, gluing or soldering.
- the filter holder 6 is mounted on the receiver 5 by means of a friction fit, a snap fit or by gluing.
- the filter/filter holder 6 is mounted in the filter socket 13 in the hearing aid housing 1, and the filter socket provides a channel to the internal cavity 8 from the outside of the hearing aid housing 1. According to the invention this passage is made sufficiently large to allow for insertion of the receiver into the internal cavity 8 through the channel. Furthermore the disclosed embodiments show that the receiver 5 is mounted on the filter holder 6 which is mounted in the filter socket 13. As shown in the figures this provides the option of having the receiver 5 suspended only by the filter holder 6, so that it does not touch any parts of the hearing aid housing 1.
