Definitions

  • the present invention relates to a receiver/loudspeaker adapted for being mounted in a hearing aid, and comprising a receiver housing having a first substantially plane side face with a sound opening, and a filter holder with a filter, such as a cerumen filter, and where the filter holder comprises a substantially plane bottom face and a sound channel extending between a first opening arranged in the substantially plane bottom face, and a second opening adapted for releasably mounting of the filter in the filter holder in the sound channel.
  • the invention also relates to a hearing aid comprising such a 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 requires reduced volume in a hearing aid.
  • the substantially plane bottom plate is fastened to the first substantially plane side face of the receiver housing.
  • the filter holder may preferably be fastened to the receiver housing by gluing, soldering or welding.
  • the receiver housing may in a preferred embodiment extend within a substantially uniform rectangular cross section in all planes parallel to the first substantially plane side face, and the filter holder may have a cylindrical outer surface defining an outer diameter, and where the diagonal dimension of the substantially uniform cross section of the receiver housing is smaller than the outer diameter of the filter holder.
  • the filter holder defines a direction of detachment of the filter from the filter socket, and the receiver/loudspeaker defines a primary direction of sound outlet being perpendicular to the substantially plane side face, and wherein the direction of detachment is arranged obliquely with respect to the primary direction of sound outlet, so that the receiver/loudspeaker is easy to build into a number of different hearing aids.
  • the angle between the direction of detachment and the primary direction of sound is within the range from 5° to 45° and preferably in the range from 10° to 30°.
  • a hearing aid according to the invention comprises a hearing aid housing with a receiver as mentioned above.
  • the hearing aid housing comprises an outer surface and an internal cavity adapted for containing the receiver and the hearing aid housing comprises a filter socket wherein the filter holder is releasably mounted, so that the filter holder provides a sound channel extending through the filter between the outer surface and the receiver housing.
  • the filter socket and the receiver are relatively sized in order to allow for insertion of the receiver housing through the channel and into the internal cavity, when the filter is dismantled from the filter socket.
  • the filter holder may in one preferred embodiment be permanently fastened to the receiver housing by gluing, soldering or welding.
  • the filter holder may be releasably attached to the receiver housing with a press fit, a frictional fit, or by means of heat releasable glue.
  • Fig. 1 and 2 shows a perspective view and a side view of one embodiment of a receiver according to the invention.
  • the receiver comprises a receiver housing 5 integral with a filter holder 6 fixed to a side face 12 of the receiver housing 5.
  • FIG. 3 and 6 are principle drawings showing a cross section through hearing aids 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 3 and 6 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 housing 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.
  • 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 at 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 housing 5.
  • the filter holder 6 shown in fig. 1, 2 , 3, 4 and 5 is made from by deep drawing a sheet of metal to the shape shown in the figures, and is thereafter fixed to the plane side face 12 of the receiver housing 5 by welding, gluing or soldering.
  • the filter holder 6 is as an alternative made from a plastic material, e.g. by injection moulding, and the filter holder 6 is thereafter mounted on the receiver housing 5 by means of a friction fit, a snap fit or by gluing.
  • receiver housing 5 and the filter holder 6 forms a sturdy connection allowing the receiver housing 5 to be suspended only by the filter holder 6.
  • the filter socket 6 is adapted for insertion and detachment of a filter unit 11, such as a cerumen filter, and so that the filter unit 11 can be inserted or detached in a direction of detachment as shown by the dotted line A in fig. 4 and 7 , and the receiver housing 5 has a plane side face 12 with a sound exit opening defining a primary direction of the sound outlet from the receiver housing 5 being perpendicular to the plane side face 12 as shown by the dotted line B in fig. 2 and 5 .
  • a filter unit 11 such as a cerumen filter
  • the filter holder 6, the sound channel 10, and the receiver housing 5 are designed so that the direction A of detachment is arranged obliquely to the primary direction B of the sound outlet.
  • the filter/filter holder 6 is mounted in the filter socket 13 in the hearing aid housing 1, and the filter socket 13 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.
  • the disclosed embodiments of a hearing aid according to the invention shows that the receiver housing 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.
