Abstract

A hearing device has a sealable housing with a wall that delimits an inner space. In addition, the hearing device has a microphone which is arranged in the inner space, and a microphone opening in the wall, as well as a protective element for protecting the microphone. The housing has a sound channel with at least one sound inlet opening, and the protective element is positioned in the sound channel.

First claim

The invention claimed is:

1. A hearing device, comprising:
a housing having a wall that delimits an inner space, said wall having a microphone opening formed therein;
a microphone disposed in said inner space;
a protective element for protecting said microphone;
said housing having a sound channel that leads to said microphone and at least one sound inlet opening formed therein, said protective element is disposed in said sound channel;
said wall having an inner wall region and an outer wall region delimiting said sound channel, said sound channel extending in a sound channel direction:
said microphone opening being oriented transversely to said sound channel;
said inner wall region having a hole formed therein forming said microphone opening;
said protective element being elastic and being gripped within said sound channel as a result of its elasticity;
said protective element being reversibly replaceable in said sound channel and said protective element configured to be pushed in the sound channel direction into said sound channel via said sound inlet opening.

2. The hearing device according to claim 1 , wherein said sound channel is configured to extend through said housing and has a respective sound inlet opening formed at each end, said sound channel being delimited by said wall and connected to said microphone via said microphone opening.

3. The hearing device according to claim 2 , wherein said housing is a sealable housing, and when said housing is closed, said protective element may be placed into said sound channel via one said sound inlet opening.

4. The hearing device according to claim 1 , wherein said protective element is disposed in said sound channel a distance apart from said at least one sound inlet opening.

5. The hearing device according to claim 1 , wherein said protective element may be guided through said sound channel.

6. The hearing device according to claim 1 , wherein for purposes of replacement, said protective element may be guided into or out of said sound channel by means of a tool.

7. The hearing device according to claim 1 , wherein said protective element is a membrane.

8. The hearing device according to claim 1 , wherein said protective element has a hydrophobic and/or oleophobic material.

9. The hearing device according to claim 1 ,
further comprising a sealing element disposed between said microphone and said inner wall.

10. The hearing device according to claim 9 , wherein said sealing element is separate from said protective element.

11. The hearing device according to claim 1 , wherein the hearing device is a behind-the-ear hearing device.

12. A hearing device, comprising:
a housing having a wall that delimits an inner space, said wall having a microphone opening formed therein;
a microphone disposed in said inner space;
a protective element for protecting said microphone;
said housing having a sound channel that leads to said microphone and at least one sound inlet opening formed therein, said protective element is disposed in said sound channel; and
a tool as an accessory, said tool having a handle part and at least one tool tip for guiding said protective element.

13. The hearing device according to claim 12 , wherein said at least one tool tip is pin-shaped and may be pushed into said sound channel.

14. The hearing device according to claim 12 , wherein said at least one tool tip is one of two tool tips that are furnished having different lengths.
