Definitions

  • the present invention relates to an adhesive film for protecting a microphone opening of a hearing device with a plastic membrane which is substantially acoustically transparent, and an adhesive layer which is applied to the plastic membrane.
  • Hearing aids are constantly exposed to a risk of contamination when carrying. Particularly sensitive are the microphone inputs, as they are acoustically designed to be as transparent as possible and on the other hand must keep dirt from the transducers.
  • such a device for closing openings in hearing aids or earmolds for hearing aids is known.
  • Such openings are used for example for the sound inlet, the sound outlet or the ventilation.
  • a microporous membrane of non-stick material used in the respective opening.
  • the membrane is inserted into the interior of a cap or injected into an opening of the cap.
  • the cap is then attached to the corresponding opening of the hearing aid. If a hearing aid has a directional microphone with several microphone openings, then these openings are to protect individually. The application of the microphone protection or its replacement is relatively cumbersome.
  • the object of the present invention is thus to present a microphone protection that is easy to attach to a hearing aid and that is easily replaceable.
  • a correspondingly designed hearing aid is to be specified, in which the microphone protection is easily attachable or replaceable.
  • the microphone protection in the form of an adhesive film without great difficulty on the microphone opening. Due to the recess of the adhesive immediately above the microphone opening, there is no damping of the sound passing through the adhesive.
  • the predetermined shape of the recess of the adhesive may consist of a dot. This point should have the same outer shape as the microphone opening. Usually, this point will be circular, but it may also take rectangular, square, triangular, oval or other shape.
  • the predetermined shape of the recess consists of two or more points. This makes it possible to mask a plurality of microphone openings, sound outlet openings and / or ventilation openings with a single adhesive film.
  • An advantageous embodiment of the adhesive film is further that it has a substantially elongated extent, wherein the two or more points of the recessed adhesive are arranged in a row parallel to the main extension direction of the adhesive film. This geometric arrangement is particularly favorable for the protection of directional microphone openings.
  • a hearing device itself which is equipped with an adhesive film according to the invention, may have in its housing in the region of the opening (s) a recess into which the adhesive film is glued, the adhesive film having substantially the same external shape as the depression. This makes it easy to attach the adhesive film exactly placed on the housing.
  • the housing of the hearing device has a common recess for gluing the adhesive film for a plurality of microphone openings.
  • the adhesive film as a microphone protection effortlessly attach.
  • the depression for the adhesive film can be formed by a separate shell inserted into the housing shell or an edge sprayed onto the housing shell.
  • the depression can be realized in a simple manner.
  • the reproduced in the side view in FIG 1 behind-the-ear hearing aid has a hearing aid shell 1, can be seen in the microphone openings 2 of a directional microphone.
  • the directional microphone openings 2 are arranged in a row, so that a corresponding directivity can be achieved.
  • the three microphone openings 2 are arranged in an elongated recess 3 in series.
  • an adhesive film 4 is viewed from the adhesive side of view. It has substantially the same contour as that of the recess 3 of the hearing aid shell 1. Thus, the film 4 can be placed exactly on the recess 3.
  • the adhesive film consists of a plastic membrane 10, with which the protective effect is achieved and which is also used as a carrier for the adhesive 5. So that no acoustic attenuations by the adhesive 5 or particles adhering thereto occur in front of the openings 2, recesses 6 are provided at the locations corresponding to the openings 2 on the adhesive film 4, in which case no adhesive 5 is applied to the membrane.
  • the adhesive film 4 can be reinforced for reasons of stability with a plastic strip, this then has in the microphone openings 2 corresponding holes 7.
  • Figure 3 is a part of such Protective device shown in cross section.
  • the plastic carrier 8 thus has a bore 7, and on it the membrane 10 is laminated.
  • the adhesive 5 is applied, wherein the adhesive recess 6 is disposed around the bore 7.
  • the protective device explained in FIG. 3 is inserted into the recess 3 with the plastic carrier 8 and the three bores 7, so that the plastic carrier 8 terminates substantially flush with the surface of the hearing device shell 1.
  • a microporous membrane can be used as the plastic membrane 10.
  • a corresponding ePTFE membrane is available from Gore. These films are grease, dirt and water repellent.
  • Teflon films and fabric films can be used according to the invention. Their acoustic attenuation should be below 2 dB, so that they can essentially be described as sound-transmissive.
  • the recess in which the microphone protection is to be glued realized by a separate shell 9, which is inserted into the housing shell 1.
  • the edge of the shell 9 has the advantage that the microphone protection can be easily placed. If this edge of the shell 9 is interrupted at one point, then the protective film can be lifted more easily, for example with the fingernail.
  • the adhesive 5 conveniently surrounds the recesses 6 completely, so that no dirt can get into the microphone openings 2 between the film 4 and the housing shell 1.
  • the microphone protection according to the invention is designed by its size here so that it is easy to handle. In particular, the handling is facilitated if the microphone protection provides a uniform protection for all microphones and so that the appropriate size is given.
  • the uniform protection of the microphone openings also has the advantage that in the case of contamination, the directional characteristics does not change, since in general all microphones are polluted in the same way.
  • Another advantage of the microphone protection according to the invention is that the bond counteracts a capillary action, since no gap between the hearing aid shell 1 and the microphone protection is formed. This prevents the penetration of sweat into the device.
  • the further advantage that the recess 3 in the housing shell 1 allows easy installation or replacement of the microphone protection has already been mentioned. Overall, the microphone protection shown in the embodiments thus offers numerous advantages.
  • a microphone protection just described can be modified somewhat also for other openings of a hearing device, e.g. Use vent or sound outlet.
