Abstract (en)
[origin: EP1389891A2] The device has a microphone (10) to acquire an acoustic input signal and to transduce it into an electrical signal. A signal processing and control unit (12) processes the electrical signal. A receiver (14A) transduces the electrical signal into an acoustic signal. An antenna coil (14B) is wound around the receiver or the microphone. The coil implements the wireless transmission of data.
