Abstract

A hearing device has a microphone for detecting an acoustic signal from the environment of the hearing device, and a housing in which the microphone is arranged. The housing is formed with a microphone opening through which the microphone communicates with the environment of the hearing device for detecting the acoustic signal. The hearing device further has a damping element, by way of which the microphone is supported against the housing. Moreover, the hearing device has a barrier element for sealing the microphone opening against moisture in a sound-transmitting manner. The damping element has a pocket in which the barrier element is received reversibly. Furthermore, the barrier element is sealed off from the housing by way of the damping element all around the microphone opening.

First claim

1 . A hearing device, comprising:
a housing, said housing having a microphone opening formed therein; a microphone disposed in said housing and communicating through said microphone opening with an environment of the hearing device for detecting an acoustic signal from the environment of the hearing device; a damping element supporting said microphone against said housing; and a barrier element sealing said microphone opening against moisture in a sound-transmitting manner; said damping element having a pocket wherein said barrier element is received reversibly; and said damping element sealing off said barrier element from said housing around an entire periphery of said microphone opening.

2 . The hearing device according to claim 1 , wherein said damping element is made of elastic material.

3 . The hearing device according to claim 2 , wherein said elastic material is an elastic plastic.

4 . The hearing device according to claim 1 , wherein said damping element is formed with an aperture corresponding to said microphone opening, and said pocket is an undercut of said aperture.

5 . The hearing device according to claim 4 , wherein said aperture has, at one end thereof, an edge delimiting said undercut, and wherein said aperture is enlarged at said one end, in relation to an opposite end of said aperture.

6 . The hearing device according to claim 4 , wherein said undercut is opened in a direction transverse to a longitudinal axis of said aperture, to thereby form an insertion well for said barrier element.

7 . The hearing device according to claim 1 , wherein said pocket is dimensioned to cause said barrier element to be braced against said damping element.

8 . The hearing device according to claim 1 , wherein said barrier element comprises a hydrophobic membrane.

9 . The hearing device according to claim 1 , wherein said microphone is a first microphone, said microphone opening is a first microphone opening, said damping element is a first damping element, and said barrier element is a first barrier element, and further comprising:
a second microphone disposed in said housing; a second damping element and a second barrier element assigned respectively to said second microphone, wherein said second barrier element is received reversibly in a pocket formed in said second damping element; and wherein said first damping element and said second damping element are connected to one another in one piece.

10 . The hearing device according to claim 9 , further comprising an antenna for electromagnetic communication with a separate device, said antenna being integrated in one or both of said first or second damping element.

11 . The hearing device according to claim 10 , further comprising a circuit carrier carrying a signal processing unit and conductor tracks for electrically contacting said first microphone, said second microphone and said antenna, wherein said antenna is connected by way of a solder connection to an assigned conductor track of said circuit carrier.

12 . The hearing device according to claim 1 , further comprising an antenna for electromagnetic communication with a separate device, said antenna being integrated in said damping element.

13 . The hearing device according to claim 12 , further comprising a circuit carrier carrying a signal processing unit and conductor tracks for electrically contacting said microphone and said antenna, wherein said antenna is connected by way of a solder connection to an assigned conductor track of said circuit carrier.
