Definitions

  • the invention relates to a hearing aid according to the preamble of claim 1.
  • a hearing aid is for example from the DE 198 25 998 A1 known.
  • Hearing aids generate acoustic feedbacks (feedback), which are caused by various design features.
  • Two key features that affect feedback are the weight and length of the hearing aid. Therefore, especially high performance hearing aids (so-called super power devices) with a high gain and heavy batteries tend to generate feedback in the acoustic range between 2 and 6 kHz. In almost all cases, therefore, sufficient amplification can not be achieved in directional microphone mode.
  • Such hearing aids are usually designed as behind-the-ear hearing aids (BTE) and have a housing which is worn behind the ear by means of a hook. The housing encloses the speaker (earphone) and houses batteries for power supply.
  • BTE behind-the-ear hearing aids
  • a hearing aid with a damping element between a main housing and a hose to the main housing is in CH 699444 B1 shown. This solution is sufficient for smaller and less powerful devices, but more powerful devices require different solutions.
  • the object of the invention is to provide a hearing aid which has reduced feedback. This object is achieved by the hearing aid according to claim 1.
  • the invention relates to a hearing aid according to claim 1, comprising a housing in which a receiver and a battery are arranged, wherein the housing has a first housing part in which the battery is arranged ausschlissslich, and a second housing part, in which the handset exclusively arranged is, wherein the housing parts are connected via a connection vibration-decoupled from each other, and wherein at least the first housing part is formed of an elastic material.
  • the connection between the first and second housing part is preferably a bayonet connection, but may also be a plug connection or a screw connection.
  • An e.g. annular or disc-shaped damping element is preferably arranged between the first and the second housing part.
  • the hearing aid may be a behind-the-ear hearing aid with a hook.
  • the hook forms the second housing part, which is connected via the connection with the first housing part, wherein a damping element is arranged in the connection.
  • the second housing part is formed of a non-elastic material.
  • the non-elastic material is a thermoset plastic, in particular ABS.
  • the elastic material is preferably an elastomeric plastic, eg silicone rubber, a thermoplastic elastomer (TPE) or a fluoroelastomer such as Viton®.
  • High weight as well as the length of the housing are the main factors for strong feedback of a hearing aid. This is especially true for heavy, powerful devices. Especially two components contribute to a high weight in heavy, powerful devices: the battery and the handset. Your weight can not be reduced without sacrificing performance. However, it is possible and inventively provided to accommodate these two components in separate, decoupled housing parts. This gives a hearing aid with two parts that vibrate independently of each other and the feedback frequencies are shifted to a higher frequency range ( ⁇ 6kHz). This is very effective, as both length and weight are reduced by vibration vibration.
  • the decoupling can be achieved by a damping element which is arranged between the first and second housing part, e.g. a ring or disc of damping material, e.g. an elastomeric material.
  • a damping element which is arranged between the first and second housing part, e.g. a ring or disc of damping material, e.g. an elastomeric material.
  • the housing part which contains the battery is preferably made of a damping material, e.g. an elastomeric material formed.
  • the other housing part receives the earphone and preferably the microphone, and is suitably made of a rigid, non-elastic material, e.g. a thermoset material or a rigid thermoplastic material.
  • FIG. 1 1 schematically shows a BTE hearing aid 1 according to the prior art, with a rigid housing 11, microphone opening 13, hook 15 and a connection 17 for a hearing tube (not shown), which leads into the ear.
  • the housing 11 is integrally formed integrally with the hook 15.
  • FIG. 2 schematically shows a first embodiment of a hearing aid 1 'according to the invention with a first housing part 111 and with a second housing part 112.
  • a battery (not shown) is arranged in the first housing part 111.
  • the microphone behind a microphone opening 13 and the receiver (not shown) are arranged in the first housing part 111.
  • the first housing part 111 is formed from an elastomeric plastic, for example TPE.
  • the connection 19 is designed as a simple plug-in or latching connection.
  • FIG. 3 schematically shows a second embodiment of a hearing aid 1 'according to the invention, with a first housing part 111 and with a second housing part 112.
  • a battery (not shown) is arranged in the first housing part 111.
  • the microphone 13 and the handset (not shown) are arranged in the second housing part 112, the microphone 13 and the handset (not shown) are arranged in the second housing part 112, the microphone 13 and the handset (not shown) are arranged.
  • the first housing part 111 is formed of a Duroplastvasesstoff.
  • the connection 19 ' is designed as a simple plug connection, wherein a damping element made of elastomeric material between the first housing part 111 and the second housing part 112 is arranged.
  • FIG. 4 schematically shows an embodiment of a hearing aid, in which the hook 151 is connected via a damped connection 191 with the first housing part 111 '.
  • a battery not shown
  • the handset not shown
  • FIG. 5 shows the hook 151 with connecting elements 193, 195, 197 according to the embodiment FIG. 4 ,
  • the connection here comprises a damping element 193 made of a damping soft material, for example TPE, and a first connecting element 195, which cooperate as a bayonet closure. In between, a second connection element 197 is arranged.
  • a damping element 193 made of a damping soft material, for example TPE
  • a first connecting element 195 which cooperate as a bayonet closure.
  • a second connection element 197 is arranged.
  • FIG. 6 shows the hook 151 with connecting elements 193, 195, 197 according to the embodiment FIG. 4 or 5 in a sectional view.
  • FIG. 7 shows a diagram illustrating the feedback behavior of the hearing aid according to the invention according to the embodiment of FIG. 2 represents.
  • This embodiment has a first housing part made of elastic and damping material, which encloses the battery of the hearing aid.
  • the dashed line shows the feedback behavior of a hearing aid with a one-piece, rigid housing according to the prior art.
  • the solid thick line shows the feedback behavior of a hearing aid according to the invention with a first housing part made of elastic and damping material.
  • the solid thin line shows the feedback behavior of a hearing aid according to the invention with a first housing part made of elastic and damping material and a damping element between the hook and the rest of the housing, resulting in a combination of the features of the embodiments FIG. 2 and FIG. 4 equivalent.
  • the sharply delimited maxima are no longer present at approximately 4 kHz and 6-7 kHz, and the frequency curve as a whole comes much closer to the desired ideal frequency response.
  • FIG. 8 shows a diagram showing the feedback behavior of the hearing aid according to the embodiment according to Figure 4-6 represents.
  • This embodiment has a damping element between the hook and the rest of the housing.
