Abstract

A hearing assistance device, including a housing, a receiver, and a cable, is provided. The housing has an ear hook and a first contour arc. The cable faces the ear hook, penetrates the housing, and connects to a receiver.

First claim

What is claimed is:

1. A hearing assistance device, comprising:
a housing, comprising a first casing that has a first contour arc and a second casing that has a depression that is away from the first contour arc, wherein the first casing is assembled with a first part of the depression, and a second part of the depression protrudes from the first casing to form an ear hook with a second contour arc;
a receiver;
a cable, facing the ear hook, penetrating the housing, and connected to the receiver, wherein the second contour arc of the ear hook matches a contour arc of the cable after penetrating the housing in an outward direction with respect to the housing, and the second contour arc of the ear hook is separated from the contour arc of the cable after penetrating the housing in the outward direction with respect to the housing;
an audio processing module, which is disposed in the housing;
a battery module, which is electrically connected to the audio processing module, wherein the audio processing module drives the receiver to make a sound when the hearing assistance device is accommodated in a charging box, but the receiver is shielded, and the battery module and the receiver are not being charged; and
a microphone, which is configured to receive the sound made by the receiver.

2. The hearing assistance device according to claim 1 , comprising a medical hearing aid and a non-medical hearing amplifier.

3. The hearing assistance device according to claim 1 , wherein the first contour arc abuts against a side edge of a helix of a user when the hearing assistance device is worn by the user.

4. The hearing assistance device according to claim 1 , wherein the first contour arc conforms to physiognomy of a helix arc.

5. The hearing assistance device according to claim 1 , wherein the ear hook abuts against an upper edge of a helix of a user when the hearing assistance device is worn by the user.

6. The hearing assistance device according to claim 1 , wherein the second contour arc conforms to physiognomy of a top of a helix arc.

7. The hearing assistance device according to claim 1 , wherein the cable penetrates the first casing.

8. The hearing assistance device according to claim 1 , wherein a back side of the housing has a crescent-like contour.

9. The hearing assistance device according to claim 8 , further having at least one button located on the crescent-like contour.

10. The hearing assistance device according to claim 1 , wherein a back side of the ear hook has an anti-slip structure.

11. The hearing assistance device according to claim 1 , wherein two opposite ends of the first contour arc form an extended straight line.

12. The hearing assistance device according to claim 11 , wherein a top end of the ear hook and a site where the cable penetrates the housing are located on a same side of the extended straight line.

13. The hearing assistance device according to claim 11 , wherein a top end of the ear hook and a site where the cable penetrates the housing are located on different sides of the extended straight line.

14. The hearing assistance device according to claim 11 , wherein a top end of the ear hook shields a site where the cable penetrates the housing.

15. The hearing assistance device according to claim 1 , wherein the housing further has a fixed structure protruding from a ventral side of the ear hook.

16. The hearing assistance device according to claim 15 , wherein the cable is bound to the fixed structure after the cable penetrates the housing.

17. The hearing assistance device according to claim 1 , further having at least one button, which is electrically connected to the audio processing module.

18. The hearing assistance device according to claim 1 , wherein the cable is electrically connected to and in between the audio processing module and the receiver.

19. The hearing assistance device according to claim 1 , wherein the battery module is a wireless battery module.

20. The hearing assistance device according to claim 1 , wherein the audio processing module correspondingly drives the receiver according to a status of the battery module.

21. The hearing assistance device according to claim 1 , wherein the audio processing module switches off the receiver when the hearing assistance device is accommodated in a charging box and the battery module is being charged.

22. The hearing assistance device according to claim 13 , wherein a side edge of the at least one button and an inflection point of the crescent-like contour define a Y1 axis of two-dimensional right-angle coordinates X1−Y1.

23. The hearing assistance device according to claim 22 , wherein a bottom end of the hearing assistance device is perpendicular to the Y1 axis, and defines an X1 axis of the two-dimensional right-angle coordinates X1−Y1.

24. The hearing assistance device according to claim 23 , wherein the bottom end is a bottom end of the crescent-like contour.

25. The hearing assistance device according to claim 24 , wherein the ear hook has a top end of the crescent-like contour, which is opposite to the bottom end.

26. The hearing assistance device according to claim 23 , wherein the housing further has two side surfaces that are opposite to each other and an anti-slip structure that is respectively located on the two side surfaces.

27. The hearing assistance device according to claim 26 , wherein a ventral side of the housing has a smooth surface, which is adjacent to and in between the two side surfaces.

28. The hearing assistance device according to claim 26 , wherein the anti-slip structure respectively located on the two side surfaces is extended and connected to each other.

29. The hearing assistance device according to claim 26 , wherein the first contour arc is located between the two side surfaces.

30. The hearing assistance device according to claim 26 , wherein the anti-slip structure has a plurality of first straight lines, and fo ns an included angle of 40-50 degrees with the X1 axis.

31. The hearing assistance device according to claim 26 , wherein the anti-slip structure has a plurality of second straight lines, and forms an included angle of 105-115 degrees with the X1 axis.

32. The hearing assistance device according to claim 26 , wherein the anti-slip structure has a plurality of third straight lines, and forms an included angle of 345-355 degrees with the X1 axis.

33. The hearing assistance device according to claim 23 , wherein the first contour arc has a curve equation Y=f(X), which is obtained through two-times coordinate transformation of the two-dimensional right-angle coordinates X1−Y1.
