Abstract

A hearing aid, in particular a behind-the-ear hearing assistance aid, contains a transmitting and/or receiving unit having an antenna element for wireless signal transmission and for wireless energy transfer to an energy store. The antenna element is formed as a foil structure, which at least sectionally encloses the energy store.

First claim

The invention claimed is:

1. A hearing aid, comprising:
an energy store having opposing end sides;
a transmitting and/or receiving unit having an antenna element for wireless signal transmission and for wireless energy transfer to said energy store, said antenna element being formed as a foil structure which at least sectionally encloses said energy store, said foil structure formed from a ferromagnetic or ferrimagnetic material, said foil structure having a first foil element, a second foil element and a third foil element, said first and second foil elements are disposed at said opposing end sides of said energy store and said third foil element overlapping a circumferential region of said energy store;
said third foil element forming a coil core of said antenna element and having a wire or coil winding; and
said first and/or second foil elements at least partially cover a respective one of said opposing end sides of said energy store.

2. The hearing aid according to claim 1 , further comprising a shield disposed between said foil structure of said antenna element and said energy store.

3. The hearing aid according to claim 2 , wherein said shield is formed from a diamagnetic or paramagnetic material, or contains said diamagnetic or paramagnetic material.

4. The hearing aid according to claim 2 , wherein said shield is at least partially covered by said foil structure of said antenna element.

5. A hearing aid, comprising:
an enemy store;
a transmitting and/or receiving unit having an antenna element for wireless signal transmission and for wireless enemy transfer to said enemy store, said antenna element being formed as a foil structure which at least sectionally encloses said energy store;
a shield disposed between said foil structure of said antenna element and said energy store;
an electronic hearing aid component; and
a flexible printed circuit board having a board surface, said shield being introduced into said flexible printed circuit board, said flexible printed circuit board bearing said electronic hearing aid component on said board surface facing toward said energy store.

6. The hearing aid according to claim 5 , wherein said foil structure is at least partially integrated into said flexible printed circuit board bearing said electronic hearing aid component.

7. The hearing aid according to claim 2 , wherein said shield has a collar-shaped jacket shield and said energy store is at least partially enclosed by said collar-shaped jacket shield.

8. The hearing aid according to claim 1 , wherein the hearing aid is a behind-the-ear hearing assistance aid.

9. The hearing aid according to claim 1 , wherein said first and/or second foil elements cover at least half of an end side surface of said respective opposing end side.

10. The hearing aid according to claim 3 , wherein said diamagnetic or paramagnetic material is copper.
