Definitions

  • the present invention relates to a hearing aid comprising a housing with a receiver/loudspeaker having a substantially plane side face with a sound outlet opening, and where the hearing aid further comprises a filter, e.g. a cerumen filter, and the housing comprises an outer surface and an internal cavity adapted for containing the receiver/loudspeaker, and a filter socket arranged in the outer surface, and wherein the filter is releasably attached, and where a sound channel is arranged between the receiver and the filter socket and being adapted for directing sound from the receiver/loudspeaker to the filter socket, and where the filter socket 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 of the receiver.
  • a filter e.g. a cerumen filter
  • the housing comprises an outer surface and an internal cavity adapted for containing the receiver/loudspeaker, and
  • 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.
  • the purpose of the present invention is therefore to provide a hearing aid where especially the receiver and the filter socket is optimally arranged with respect to provide a good sound quality on the one hand, and a reduced volume required for the components, especially the filter socket and the receiver.
  • a hearing aid as mentioned in the introduction, and by arranging the receiver and the filter socket so that the direction of detachment is arranged obliquely with respect to the primary direction of sound outlet.
  • the hearing aid can be designed so that the filter socket is placed very deep in the ear channel, and thereby also the receiver can be moved to a position in the hearing aid further into the ear when the ITE hearing aid is positioned in the ear.
  • the sound channel and the receiver/loudspeaker are relatively sized in order to allow for insertion of the receiver/loudspeaker through the filter socket and the sound channel and into the internal cavity, when the filter is detached from the filter socket. This provides the option of servicing/exchanging the receiver by pulling it out of the hearing aid through the filter socket, so that it is not necessary to remove the face plate and other components from the hearing aid when accessing the receiver.
  • the filter may preferably comprise 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 may advantageously comprise a receiver housing having a first substantially plane side face with a sound opening, and the filter holder comprises a substantially plane bottom plate, and where 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 is fastened to the first substantially plane side face of the receiver housing.
  • the receiver and filter are easily removed as a unit by permanently fastening the filter holder to the receiver housing by gluing, soldering or welding and by arranging 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 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° being most suitable for ITE hearing aids due to the complex geometry of the ear channel.
  • 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.
  • ITE in the ear
  • 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 socket 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 on the hearing aid housing 1.
  • This pressure equalizing channel 7 must be arranged so that it is possible, e.g. via a tube extending from the pressure equalizing channel 7 and to a corresponding opening in the face plate 2 (not shown), to equalize pressure differences between the environment 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 6 is arranged in the end of the hearing aid housing facing the inside of the ear of the user, and a sound channel 10 extending between the filter socket 6 and the receiver 5.
  • the filter socket 6 shown in fig. 1, 2 and 3 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 5 by welding or soldering.
  • the filter socket 6 is as an alternative made from a plastic material, e.g. by injection moulding, and the filter socket 6 is thereafter mounted on the receiver 5 by means of a friction fit, a snap fit or by gluing.
  • 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. 2 and 5 , and the receiver 5 has a plane side face 12 with a sound exit opening defining a primary direction of the sound outlet from the receiver 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 socket 6, the sound channel 10, and the receiver 5 are designed so that the direction of detachment A is arranged obliguely to the primary direction of the sound outlet B.
