Abstract

A hearing instrument includes a housing, a printed circuit board, a signal processor on the printed circuit board, wherein the signal processor is configured for generating an audio signal, and a receiver that is connected to an output of the signal processor for converting the audio signal into a sound signal, wherein the housing is configured to accommodate the receiver and the printed circuit board with the signal processor, and the housing has a trunk part that is coupled with a tip part, and wherein the printed circuit board forms a wall within the housing extending transversely relative to a longitudinal extension of the trunk part.

First claim

The invention claimed is:

1. A hearing instrument, comprising:
a housing;
a printed circuit board;
a signal processor on the printed circuit board, wherein the signal processor is configured for generating an audio signal; and
a receiver that is connected to an output of the signal processor for converting the audio signal into a sound signal;
wherein the housing is configured to accommodate the receiver and the printed circuit board with the signal processor, and the housing has a trunk part that is coupled with a tip part; and
wherein the printed circuit board extends transversely relative to a longitudinal extension of the trunk part; and
wherein the printed circuit board forms a wall partitioning a space in the housing into a first space and a second space.

2. The hearing instrument according to claim 1 , wherein the housing is configured for placement in an ear canal, and wherein the housing does not obstruct the ear canal when positioned in its intended operational position in the ear canal.

3. The hearing instrument according to claim 1 , wherein the receiver is accommodated in the tip part of the housing.

4. The hearing instrument according to claim 3 , wherein the wall formed by the printed circuit board is in the trunk part of the housing.

5. The hearing instrument according to claim 1 , wherein the printed circuit board further comprises connector pads for connection with programming equipment for the hearing instrument.

6. The hearing instrument according to claim 1 , wherein the trunk part of the housing further comprises a connector for making mechanical and electrical contact with the receiver.

7. The hearing instrument according to claim 1 , wherein the wall formed by the printed circuit board comprises connector pads for connection with a battery.

8. The hearing instrument according to claim 7 , further comprising first springs coupled with the connector pads for connection of the printed circuit board with the battery.

9. The hearing instrument according to claim 8 , wherein the first springs provide a mechanical snap fit coupling of the printed circuit board to the housing.

10. The hearing instrument according to claim 7 , further comprising:
an elongate member attached to the housing; and
springs connected with signal lines in the elongate member;
wherein the elongate member is configured for placement in a pinna and outside an ear canal of a user for retention of the housing in the ear canal.

11. The hearing instrument according to claim 10 , wherein the springs provide a mechanical snap fit coupling of the printed circuit board to the housing.

12. The hearing instrument according to claim 1 , further comprising a protective material covering at least a part of the printed circuit board, wherein the protective material is accommodated in the housing.

13. The hearing instrument according to claim 1 , wherein the tip part is custom made to fit an ear canal, and the trunk part is manufactured in a standard size.

14. The hearing instrument according to claim 1 , wherein the tip part and the trunk part are manufactured in respective standard sizes.

15. The hearing instrument according to claim 14 , wherein the housing further comprises a custom made part fitting around the standard-sized tip part for fitting the housing to an ear canal.

16. The hearing instrument according to claim 14 , wherein the housing further comprises a flexible part fitting around the standard-sized tip part for fitting the housing to an ear canal.

17. The hearing instrument according to claim 16 , wherein the flexible part is manufactured in a standard size.

18. The hearing instrument according to claim 1 , wherein the tip part of the housing is flexible.

19. The hearing instrument according to claim 1 , further comprising a cerumen filter that is configured to be fitted on the tip part of the housing with a snap on coupling.

20. The hearing instrument according to claim 1 , further comprising an elongate member that is removably attached to the housing, the elongate member configured for placement in a pinna and outside an ear canal of a user for retention of the housing in the ear canal.

21. The hearing instrument according to claim 20 , wherein the elongate member is manufactured in a standard size.

22. The hearing instrument according to claim 20 , wherein the elongate member has a longitudinal shape with a first end attached to the housing and an opposite second end.

23. The hearing instrument according to claim 1 , further comprising an elongate member, wherein the housing comprises a battery door removably attached to the trunk part of the housing, and wherein the elongate member is attached to the battery door.

24. A hearing instrument, comprising:
a housing;
a printed circuit board;
a signal processor on the printed circuit board, wherein the signal processor is configured for generating an audio signal; and
a receiver that is connected to an output of the signal processor for converting the audio signal into a sound signal;
wherein the housing is configured to accommodate the receiver and the printed circuit board with the signal processor, and the housing has a trunk part that is coupled with a tip part; and
wherein the printed circuit board forms a wall that extends transversely relative to a longitudinal extension of the trunk part, the wall partitioning a space in the housing into a first space and a second space;
wherein the housing comprises a battery door removably attached to the trunk part of the housing, and wherein the elongate member is attached to the battery door; and
wherein the housing further comprises a connector for making electrical contact with a signal line in the elongate member when the battery door is attached to the trunk part of the housing.

25. The hearing instrument according to claim 1 , further comprising a tinnitus relieving circuit within the housing.

26. The hearing instrument according to claim 1 , further comprising a noise cancelling circuit within the housing.

27. The hearing instrument according to claim 1 , wherein the wall comprises an end wall of the trunk part of the housing.

28. The hearing instrument according to claim 1 , wherein the printed circuit board is next to an end wall portion of the housing in a side-by-side configuration.

29. The hearing instrument according to claim 28 , wherein in the side-by-side configuration, a plane of the printed circuit board corresponds with a plane of the end wall portion.

30. The hearing instrument according to claim 12 , wherein the printed circuit board is casted in the protective material.

31. The hearing instrument according to claim 1 , wherein the first space accommodates a first circuit component, the second space accommodates a second circuit component, and the wall formed by the printed circuit board is between the first circuit component and the second circuit component.
