Abstract

A hearing aid device includes a processing unit and a receiving unit adapted to be coupled to transmit an electrical signal from the processing unit to the receiving unit. The processing unit has a wireless transmitter and a transmitter seal for covering the wireless transmitter and the receiving unit has a wireless receiver and a receiver seal for covering the wireless receiver. The electrical signal is transmitted from the wireless transmitter to the wireless receiver wirelessly. The electrical signal may be transmitted by induction. The transmitter seal and the receiver seal prevent any environmental influences from acting on the hearing aid device and thus protect the hearing aid device from malfunctioning or becoming short circuited. Magnetic connectors and/or mechanical connectors are provided for a stable contact between the processing unit and the receiving unit.

Claims

1. A processing unit for a hearing aid device, the processing unit comprising:

a coupling adapted to couple the processing unit to a receiving unit;

a wireless transmitter adapted to transmit an electrical signal to the receiving unit wirelessly; and

a transmitter seal for covering said wireless transmitter.

2. The processing unit according to claim 1, wherein said wireless transmitter is an inductive transmitter adapted to transmit an electrical signal to the receiving unit by induction.

3. The processing unit according to claim 2, wherein said wireless transmitter includes a transmitting inductive coil adapted to generate a magnetic field to transmit the electrical signal.

4. The processing unit according to claim 1, which further comprises a transmitter seal adapted to seal a portion of a surface of the processing unit.

5. The processing unit according to claim 1, wherein a surface of the processing unit has a shape adapted to be physically aligned to a surface of the receiving unit.

6. The processing unit according to claim 1, wherein said coupling is a mechanical connector adapted to attach the receiving unit to the processing unit.

7. The processing unit according to claim 1, wherein said coupling is a magnetic connector adapted to attach the receiving unit to the processing unit.

8. The processing unit according to claim 1, wherein the processing unit is adapted to be placed behind the ear.

18. The hearing aid device according to claim 17, wherein said processing unit is constructed according to claim 1.

9. A receiving unit for a hearing aid device, the receiving unit comprising:

a coupling adapted to couple the receiving unit to a processing unit;

a wireless receiver adapted to receive an electrical signal from the processing unit wirelessly; and

a receiver seal for covering said inductive receiver.

10. The receiving unit according to claim 9, wherein said wireless receiver is an inductive receiver adapted to receive an electrical signal from the processing unit by induction.

11. The receiving unit according to claim 10, wherein said wireless receiver includes a receiving inductive coil adapted to detect a magnetic field for receiving the electrical signal.

12. The receiving unit according to claim 9, which further comprises a physical plug adapted to be connected to the processing unit.

13. The receiving unit according to claim 9, which further comprises a receiver seal adapted to seal a portion of a surface of the receiving unit.

14. The receiving unit according to claim 9, wherein a surface of the receiving unit has a shape adapted to be physically aligned to a surface of the processing unit.

15. The receiving unit according to claim 9, wherein said coupling is a mechanical connector adapted to attach the processing unit to the receiving unit.

16. The receiving unit according to claim 9, wherein said coupling is a magnetic connector adapted to attach the processing unit to the receiving unit.

17. A hearing aid device, comprising:

a processing unit having a wireless transmitter and a transmitter seal for covering said wireless transmitter; and

a receiving unit having a wireless receiver and a receiver seal for covering said wireless receiver;

said processing unit and said receiving unit being adapted to be coupled together to wirelessly transmit an electrical signal from said wireless transmitter of said processing unit to said wireless receiver of said receiving unit.

19. The hearing aid device according to claim 17, wherein said receiving unit is constructed according to claim 9.

20. The hearing aid device according to claim 17, wherein:

said processing unit having said wireless transmitter adapted to transmit an electrical signal to said receiving unit wirelessly and said transmitter seal for covering said wireless transmitter, includes a coupling adapted to couple said processing unit to said receiving unit; and
