Abstract

The present invention relates to an antenna module for a hearing device. The antenna module comprises a hollow core provided with an axial passageway and a winding around the core which is connectable with a hearing device. The antenna module is arranged to be at least partially contained within the ear canal of a user. This enables the antenna to be separated from sources of interference, since it can be positioned inside the ear canal away from hearing device electronics, thus reducing requirements for shielding and/or compensation. The invention further relates to an ear tip and a hearing device comprising such an antenna module.

First claim

What is claimed is:

1. Antenna module for a hearing device comprising a hollow core and a winding provided around said core and connectable with said hearing device, wherein said core comprises an axial passageway through the core and said antenna module is adapted to be at least partially containable within the ear canal of a user, and wherein at least one tube is connected with said axial passageway, said at least one tube connecting the axial passageway to a receiver unit and channeling an acoustic output of the receiver unit through the axial passageway.

2. Antenna module according to the claim 1 , wherein said antenna module is adapted to be completely contained within the ear canal of a user.

3. Antenna module according to claim 1 , wherein the said at least one tube passes through said axial passageway.

4. Antenna module according to claim 1 , wherein the said at least one tube is arranged in at least one extremity of said axial passageway.

5. Antenna module according to claim 1 , wherein a tube is arranged in each extremity of said axial passageway.

6. Ear tip for a hearing device comprising an antenna module according to claim 1 .

7. Ear tip according to claim 6 , wherein said ear tip comprises a shell, and said antenna module is arranged inside or outside of said shell.

8. Ear tip according to claim 6 wherein said shell comprises a seat located on the inside of said shell and conformed to support said antenna module, and wherein said antenna module is supported by said seat.

9. Ear tip according to claim 8 , wherein said antenna module is bonded to said seat.

10. Ear tip according to claim 9 , wherein the antenna module is bonded to said seat by means of glue.

11. Hearing device comprising an antenna module according to claim 1 .

12. Hearing device according to claim 11 , wherein said hearing device is of the Behind-The-Ear-type, or of the In-The-Ear-type, or of the Completely-In-the-Canal-type.

13. Hearing device according to claim 11 , wherein said hearing device comprises a shell, and wherein said shell comprises a seat located on the inside of said shell and conformed to support said antenna module, and wherein said antenna module is supported by said seat.

14. Hearing device according to claim 13 , wherein said antenna module is bonded to said seat.

15. Ear tip according to claim 14 , wherein the antenna module is bonded to said seat by means of glue.

16. Hearing device according to claim 11 , further comprising a wax guard.

17. Hearing device according to claim 11 , further comprising an ear tip, wherein the ear tip includes the antenna module.
