Abstract

A configuration and an associated method for the wireless transmission of data between hearing devices include an external unit which generates and emits a carrier signal, a first hearing device with a first transponder which modulates and back-scatters the carrier signal and a second hearing device with a second transponder which receives the carrier signal that is scattered backwards and forwards and modulated by the first transponder. The external unit is, for instance, a hearing device remote control. Advantageously, little or no additional energy is needed in the hearing device for the wireless data transmission. The energy for the supply of the first transponder is delivered by the carrier signal of the external unit.

Claims

1. A configuration for wireless data transmission between hearing devices, the configuration comprising:

an external unit generating and emitting a carrier signal;

a first hearing device with a first transponder modulating and back-scattering the carrier signal; and

a second hearing device with a second transponder receiving the carrier signal back-scattered and modulated by the first transponder.

2. The configuration according to claim 1, wherein the carrier signal is high-frequency.

3. The configuration according to claim 2, wherein the frequency of the carrier signal is in the UHF range.

4. The configuration according to claim 1, wherein said first transponder is configured to be supplied with operating power exclusively by the carrier signal.

5. The configuration according to claim 1, wherein the modulated carrier signal contains data to be transmitted from said first to said second hearing device.

6. The configuration according to claim 1, wherein said first transponder includes a first antenna and said second transponder includes a second antenna.

7. The configuration according to claim 1, wherein said external unit is a hearing device remote control.

8. A method for wireless data transmission between hearing devices, the method comprising the following steps:

emitting a carrier signal with an external unit;

modulating the carrier signal with a first hearing device;

back-scattering the modulated carrier signal with the first hearing device; and

receiving the back-scattered and modulated carrier signal with a second hearing device.

9. The method according to claim 8, which further comprises supplying the first hearing device with operating power by the carrier signal.

10. The method according to claim 8, wherein the carrier signal is high-frequency.

11. The method according to claim 10, wherein the frequency of the carrier signal is in the UHF range.

12. The method according to claim 8, which further comprises transmitting data from the first to the second hearing device by modulating the carrier signal.

13. The method according to claim 8, which further comprises modulating and back-scattering the carrier signal with a first transponder in the first hearing device.

14. The method according to claim 8, which further comprises carrying out the modulation of the carrier signal with an amplitude modulation or a phase modulation.
