Abstract

A hearing aid device includes at least one user input unit for controlling an operation mode of the hearing aid device, at least one signal line connecting the at least one user input unit with a control unit for controlling the hearing aid device, and an antenna module comprising at least two electrically conductive and electrically connectable layers forming a layered structure. The at least one user input unit is arranged at one of the layers of the antenna module, and the at least one signal line is provided at an inner surface of one of the layers facing one other layer.

First claim

The invention claimed is:

1. A hearing aid device, comprising
a stimulating device for converting a sound signal into mechanical vibrations,
an abutment connector configured to fixture the hearing aid device to a skull of a recipient of the hearing aid device,
at least one user input unit for controlling an operation mode of the hearing aid device,
at least one signal line connecting the at least one user input unit with a control unit for controlling the hearing aid device, wherein the control unit is arranged within the hearing aid device, and
an antenna module comprising at least two electrically conductive and electrically connectable layers forming a layered structure,
wherein the at least one user input unit is arranged at one of the layers of the antenna module,
wherein the at least one signal line is provided at an inner surface of one of the layers facing one other layer,
wherein the abutment connector is arranged on a first side of the stimulating device, and wherein an active part of the antenna module is arranged on an opposite side to the first side,
wherein the antenna module is, with reference to a first direction, perpendicular to a thickness direction of the layered structure, composed of a first portion, an antenna feed connection and an antenna short connection, wherein the antenna feed connection and the antenna short connection are separated by a distance in a second direction perpendicular to the first and the thickness direction, and
wherein the at least one signal line is passing through the antenna short connection in one of the interior layers of the layered structure of the antenna module.

2. The hearing aid device according to claim 1 , wherein radiation and bandwidth properties of the antenna module are settable by at least one of the distance between the antenna feed connection and the antenna short connection in the second direction, and a distance between the distal end of the first portion of the antenna module and a main ground plane portion of the hearing aid device in the first direction.

3. The hearing aid device according to claim 1 , wherein the antenna module, with reference to the first direction further comprises a bendable portion connecting the first portion with a second portion, wherein the bendable portion is provided at a distal end of the first portion opposed to the antenna feed connection and the antenna short connection, and wherein the antenna module further comprises the second portion.

4. The hearing aid device according to claim 3 , wherein the radiation and bandwidth properties of the antenna module are further settable by a length of the antenna module in the first direction consisting of the first portion, the bendable portion and the second portion of the antenna module.

5. The hearing aid device according to claim 1 , wherein one of the two or more electrically conductive layers is a ground layer.

6. The hearing aid device according to claim 5 , wherein the antenna short connection is connected with the ground layer.

7. The hearing aid device according to claim 1 , wherein the first portion of the antenna is a Planar Inverted F-Antenna PIFA antenna.

8. The hearing aid device according to claim 5 , wherein the at least one user input unit is contained in the ground layer of the antenna module.

9. The hearing aid device according to claim 1 , wherein the at least one signal line is located in a layer different from the ground layer, and
the at least one signal line is connected to the ground layer by means of capacitors.

10. The hearing aid device according to claim 9 , wherein the capacitors are placed at least at one of a position next to the user input unit, a position next to the bendable portion located at the distal end of the first portion of the antenna, and at a position next to the antenna short connection at the main ground plane portion.

11. The hearing aid device according to claim 8 , wherein the antenna module is provided with an inductive element configured to electrically decouple the antenna module from the stimulating device.

12. The hearing aid device according to claim 1 , wherein the abutment connector is arranged closer to the skull of the recipient than the active part of the antenna module.

13. The hearing aid device according to claim 1 , wherein radiation and bandwidth properties of the antenna module are settable by at least one of the distance between the antenna feed connection and the antenna short connection in the second direction, and a distance between the distal end of the first portion of the antenna module and a main ground plane portion of the hearing aid device in the first direction.

14. The hearing aid device according to claim 2 , wherein the first portion of the antenna is a Planar Inverted F-Antenna PIFA antenna.

15. The hearing aid device according to claim 3 , wherein the first portion of the antenna is a Planar Inverted F-Antenna PIFA antenna.

16. The hearing aid device according to claim 4 , wherein the first portion of the antenna is a Planar Inverted F-Antenna PIFA antenna.

17. The hearing aid device according to claim 5 , wherein the first portion of the antenna is a Planar Inverted F-Antenna PIFA antenna.
