Abstract

A hearing device has a housing in which a receiver is arranged as an electrical component. An antenna arrangement is formed, which has a winding in the form of a coil, which is arranged around the receiver with the interposition of a shielding foil. The shielding foil has a section extending around the receiver and several lugs adjoining it, which project beyond the receiver, the lugs enclosing between them an interspace adjoining the receiver. The shielding foil has in particular two layers, namely a magnetic layer and an electrical shielding layer. By this arrangement an antenna arrangement with high sensitivity is formed and at the same time a shielded partial area is created in the inter-space in which further components can be arranged. Due to the design of the lugs, which are particularly flexible, they can be attached to an inner wall of a housing.

First claim

The invention claimed is:

1. A hearing device, comprising:
a housing;
at least one electrical component disposed in said housing, said at least one electrical component extending in a longitudinal direction from a first end to a second end;
an antenna configuration having a winding disposed on said at least one electrical component; and
a magnetic layer disposed between said winding and said at least one electrical component, said magnetic layer having a section disposed on said at least one electrical component and lugs adjoining said section in the longitudinal direction, all of said lugs projecting beyond said second end of said at least one electrical component in the longitudinal direction, said lugs delimiting an interspace adjoining said second end of said at least one electrical component in the longitudinal direction.

2. The hearing device according to claim 1 , wherein said interspace widens when viewed in the longitudinal direction.

3. The hearing device according to claim 1 , wherein said housing has an inner wall and said at least one lug at least partially abuts said inner wall.

4. The hearing device according to claim 1 , wherein said at least one lug is flexible in bending or connects to said section via at least one articulated joint.

5. The hearing device according to claim 1 , wherein said magnetic layer contains a foil.

6. The hearing device according to claim 1 , further comprising an electrical shielding layer in addition to said magnetic layer.

7. The hearing device according to claim 6 , wherein said electrical shielding layer is disposed in an area which is selected at least from one of an area of said at least one electrical component and an area of said at least one lug.

8. The hearing device according to claim 6 , wherein said electrical shielding layer is formed at least in some areas as a shielding foil.

9. The hearing device according to claim 6 , wherein said magnetic layer and said electrical shielding layer form a multi-layer shielding foil at least in partial areas.

10. The hearing device according to claim 6 , wherein said electrical shielding layer is thinner than said magnetic layer.

11. The hearing device according to claim 6 , wherein said electrical shielding layer projects beyond said magnetic layer in the longitudinal direction.

12. The hearing device according to claim 6 , wherein at least one of said electrical shielding layer or said magnetic layer widens in a region of said at least one lug starting from said section.

13. The hearing device according to claim 6 , wherein said electrical shielding layer in an area of said at least one lug is at least largely or completely closed in a circumference.

14. The hearing device according to claim 6 , wherein said magnetic layer is formed by individual strips which are applied to said electrical shielding layer.

15. The hearing device according to claim 1 , further comprising at least one further component disposed in said interspace, said at least one further component is selected from the group consisting of: a battery, an integrated circuit, a signal processing device, a charging coil, a telecoil and additional coils.

16. The hearing device according to claim 1 , further comprising a printed circuit board foil having at least one layer selected formed from said magnetic layer or said electrical shielding layer.

17. The hearing device according to claim 16 , further comprising a further electrical component disposed on said printed circuit board foil, said further electrical component is disposed in said interspace.

18. The hearing device according to claim 1 , where said at least one electrical component is a receiver.

19. The hearing device according to claim 1 , wherein said at least one lug is configured as reflecting surfaces for high frequency radiation.

20. The hearing device according to claim 1 , wherein the hearing device is an in-the-ear hearing device.
