Abstract

A hearing aid has a hearing aid module for supplying electrical energy and has a transmitting and receiving unit for communication with another device. The hearing aid module has an accumulator and a charging circuit for charging the accumulator. The charging circuit is formed for contactless, in particular inductive, charging of the accumulator. The hearing aid module further has a charging conductor loop. The transmitting and receiving unit has a radio conductor loop and the radio conductor loop is integrated into the hearing aid module.

First claim

The invention claimed is:

1. A hearing aid, comprising:
a hearing aid module for supplying electrical energy and having a transmitting and receiving unit for communication with a further device, said hearing aid module further having an accumulator and a charging circuit for charging said accumulator, said charging circuit formed for contactless charging of said accumulator and having a charging conductor loop; and
said transmitting and receiving unit having a radio conductor loop, said radio conductor loop being integrated into said hearing aid module;

said accumulator extending along a central longitudinal axis with said radio conductor loop disposed running in a circumferential direction about said central longitudinal axis and about said accumulator or said hearing module having a base body extending along said central longitudinal axis with said radio conductor loop disposed running in said circumferential direction about said central longitudinal axis and about said base body.

2. The hearing aid according to claim 1 , wherein:
said charging conductor loop is disposed in such a way that said charging conductor loop runs in a circumferential direction about the central longitudinal axis and about said accumulator or said base body.

3. The hearing aid according to claim 1 , wherein:
said hearing aid module has a first longitudinal section and a second longitudinal section that follow a hearing aid module extent along the central longitudinal axis;
said charging conductor loop is disposed in said first longitudinal section; and
said radio conductor loop is disposed in said second longitudinal section.

4. The hearing aid according to claim 1 , wherein:
said charging conductor loop abuts said accumulator or said base body.

5. The hearing aid according to claim 1 , wherein said hearing aid module has a shielding body.

6. The hearing aid according to claim 1 , wherein said hearing aid module has an auxiliary body in which at least a partial volume has ferrimagnetic properties.

7. The hearing aid according to claim 6 , wherein said radio conductor loop abuts said auxiliary body.

8. A hearing aid, comprising:
a hearing aid module for supplying electrical energy and having a transmitting and receiving unit for communication with a further device, said hearing aid module further having an accumulator and a charging circuit for charging said accumulator, said charging circuit formed for contactless charging of said accumulator and having a charging conductor loop; and
said transmitting and receiving unit having a radio conductor loop, said radio conductor loop being integrated into said hearing aid module;

said hearing aid module having a shielding body separating said charging conductor loop from said radio conductor loop.

9. A hearing aid, comprising:
a hearing aid module for supplying electrical energy and having a transmitting and receiving unit for communication with a further device, said hearing aid module further having an accumulator and a charging circuit for charging said accumulator, said charging circuit formed for contactless charging of said accumulator and having a charging conductor loop; and
said transmitting and receiving unit having a radio conductor loop, said radio conductor loop being integrated into said hearing aid module;
said accumulator extending along a central longitudinal axis or said hearing aid module having a base body extending along said central longitudinal axis;

said hearing aid module having a first radial section extending in a radial direction transversely to the central longitudinal axis, an intermediate section following said first radial section in the radial direction and a second radial section in turn, following a said intermediate section in the radial direction;
said charging conductor loop disposed in said first radial section; and
said radio conductor loop disposed in said second radial section.

10. The hearing aid according to claim 9 , further comprising a ferrimagnetic auxiliary film disposed in said intermediate section.

11. The hearing aid according to claim 10 , wherein said base body is made of a ferrimagnetic material having a magnetic permeability μ base body and the magnetic permeability μ base body is smaller than a magnetic permeability μ auxiliary film of said ferrimagnetic auxiliary film.

12. The hearing aid according to claim 9 , further comprising a shielding film disposed in said intermediate section.

13. The hearing aid according to claim 12 , wherein said shielding film has a number of recesses formed therein.

14. The hearing aid according to claim 12 , wherein said shielding film has a gap formed therein extending in a direction of the central longitudinal axis.

15. The hearing aid according to claim 14 , wherein said hearing aid module has a switchable bridge circuit and said gap can be bridged via said switchable bridge circuit.

16. The hearing aid according to claim 9 , further comprising a switchable short-circuit conductor loop disposed in said intermediate section.

17. A binaural hearing aid set, comprising:
two hearing aids, each of said two hearing aids being formed as a hearing aid according to claim 1 .

18. A hearing aid module formed for a hearing aid as well as for supplying electrical energy to the hearing aid, the hearing aid module comprising:
an accumulator; and
a charging circuit for charging said accumulator, said charging circuit is formed for contactless charging of said accumulator and having a charging conductor loop, said charging circuit further having a radio conductor loop to form a transmitting and receiving unit of the hearing aid;
