Definitions

  • the present invention relates to a sound transmission device, in particular for hearing aids.
  • FIG. 1 is a schematic representation of a conventional hearing system 1 shown, which in a known manner substantially a hearing aid or microphone 2 with an on / off switch 5, a sound tube 3, which essentially forms a hearing channel, and a sound transmission device 4 comprises.
  • the hearing device 2 can be arranged behind an ear of a user, while the sound transmission device 4 is arranged in the ear canal.
  • FIG. 2 a detail view of the sound transmission device 4 is shown in a cross-sectional view.
  • the sound transmission device 4 comprises a screen-like outer component 5, the so-called dome, which is adapted to the anatomy of the ear, i. of the ear canal, and an inner component 10, the so-called earpiece protection, which in conjunction with a foil-like element 20 is intended to prevent cerumen from flowing into the sound tube 3 or the hearing aid 2, thus disturbing the sound transmission.
  • the outer component 7 is made of silicone TPE
  • the inner component 10 and the film-like component 20 are each made of compared to silicone harder polyethylene (PE).
  • the film 20 is bonded to the inner component 10 by thermal welding.
  • the sound tube 3 is inserted substantially into a passage opening 11 at one end 15 of the outer component 7, wherein the sound tube 3 against one in the passage opening 11 arranged radial projection 12 abuts to take a more or less defined position relative to the sound transmission device, so as to achieve certain acoustic conditions resulting from the shape and arrangement of the sound tube, and to avoid feedback.
  • the outer component 7 has openings 20, which on the one hand serve to equalize or pass high tones, and on the other hand to avoid complete obstruction of the ear canal.
  • the outer component 7 and the inner component 10 are usually assembled by means of a mounting device, i. the inner component 10 is inserted into the outer component 7.
  • the two components must have a relatively high dimensional stability, on the one hand to achieve a required mechanical stability when inserting into the ear and removing it from the ear, and on the other hand to achieve the desired acoustics within the sound transmission device 4.
  • the invention proposes a sound transmission device, comprising: an outer component; an inner component, wherein the outer component at least partially surrounds the inner component, and wherein at least the inner Component has a through opening; and a sheet-like component closing the passage opening of the inner component on one side; wherein the outer and the inner components are integrally connected to each other by means of a multi-component injection molding in one step.
  • An advantage of the present invention is that due to the nature of the production by means of multi-component injection molding a relatively firm connection between the inner and outer component, so that twisting or tilting of the two components to each other is excluded. Constant relative positions of the two components relative to one another are particularly important because the acoustics in the auditory canal are changed in an undesired manner even with the smallest changes in these relative positions.
  • a further advantage is that the production of the sound transmission device is simplified by applying the multi-component injection molding process, since the inner and outer components are manufactured in one work step. Moreover, thus, the sound transmission device can also be made relatively smaller.
  • the outer component is made of a material having a lower hardness than the inner component.
  • This has the advantage that the outer component can adapt relatively well to the anatomy of the ear of the wearer, and is comfortable to wear for the wearer for a long time. At the same time gives the relatively harder material of the inner component of the sound transmission device as a whole, a good strength.
  • the material for the outer component of silicone is preferred, and as the material for the inner component and for the film-like component in each case polyethylene, wherein the film-like component is preferably connected by means of thermal welding to the inner component.
  • the passage opening has connecting means which are suitable for connecting the sound transmission device in a defined manner to an external hearing device.
  • the connecting means may comprise, for example, at least one thread or a kind of bayonet closure, so as to connect the sound transmission device in a simple and defined manner with the sound tube.
  • this prevents the sound tube from being inadvertently separated from the sound transmission device when the sound transmission device is withdrawn from the ear canal of the ear.
  • FIG. 3 shows a sound transmission device 104 according to the present invention.
  • the sound transmission device 104 comprises an outer component 107 and an inner component 110, which are produced by a two-component injection molding process in one work step, and thus form a single unit of two different material components.
  • the outer component 107 is made of relatively soft silicone
  • the inner component 110 is made of relatively hard polyethylene consists.
  • the outer component is made of a softer material than the inner component because the outer component should conform well to the ear canal anatomy.
  • the outer component 107 completely covers the inner component 110; However, it is also conceivable that the outer component 107, the inner component 110 only partially covered.
  • the shape of the sound transmission device 104 substantially corresponds to the shape of the in FIG. 2 illustrated sound transmission device 4, that is, the outer component 107 has openings 120, which serve on the one hand for air equalization or passage of high tones, and on the other hand to avoid complete obstruction of the ear canal.
  • the inner component 110 has a passage opening 111, which serves as part of the auditory canal for the transmission of sound, which is emitted by a hearing device via a sound tube (not shown here).
  • a suitable sound tube is introduced into the passage opening 111 at one end 115 of the sound transmission device 104, and defined in a defined manner relative to the inner component 110 by means of a thread 117.
  • a thread 117 for example, bayonet lock is conceivable to produce a secure and defined connection between a sound tube and the sound transmission device 104.
  • a radial projection 112 in the passage opening 111 serves as a stop for a sound tube.
  • the passage opening 111 is closed by a foil 120. This should, as described above, avoid that Cerumen penetrates into the auditory canal, and thus affects the function of the entire hearing system.
  • the film 120 is integrally formed with the inner component 110 in the illustrated example. However, it is also conceivable that the film is connected to the inner component 110, for example by means of thermal welding, laser welding or gluing.
