Abstract:
1. A device for transmitting and receiving data for remotely controlling a hearing device, comprising: a transmission device comprising a transmitter coil to transmit data; a reception device comprising a receiver coil for receiving data; a common ferromagnetic core on which both said transmitter coil and said receiver coil are wound, also causing said receiver coil to be excited for transmission of data by said transmitter coil; said reception device comprising a reception oscillator circuit with said receiver coil forming an oscillator circuit coil for said oscillator circuit; said transmission coil having an inductance associated therewith and said reception oscillator circuit having a resonant frequency; and said reception device comprising a correction capacitor that corrects the frequency of the reception oscillator circuit upon deviation from said resonant frequency caused by said inductance of said transmission coil.
