Abstract: A wireless transmitter includes an antenna and a signal generator. A control signal input to the signal generator controls a frequency band of a carrier frequency. The control signal also controls the transmitted signal power. The control signal is generated by a decoder unit that decodes an audio signal.

Abstract: A wireless microphone (1) comprises a radio transmitter for transmitting radio signals carrying audio signals to a hearing device. The wireless microphone (1) further comprises at least one coupling element (11) for detachably fixing one of various interchangeable functional modules (2) to the wireless microphone (1). The coupling element (11) is designed to fix the interchangeable functional module (2) to the wireless microphone (1) by mating with a coupling element (21) of the interchangeable functional module (2). The coupling elements (11, 21) comprise electrical contacts (12, 22) for electrically connecting the interchangeable functional module (2) to the wireless microphone (1) when the interchangeable functional module (2) is fixed to the wireless microphone (1) by means of said coupling elements (11, 21). The coupling element (11) constitutes a bidirectional electrical interface between the wireless microphone (1) and the interchangeable functional module (2).

Abstract: A mobile transceiver (1) comprises several receivers (16a, 16b, 16c, 17, 18, 19) for receiving electrical or electromagnetic signals carrying audio signals and a radio transmitter (15) for transmitting radio signals carrying audio signals. The mobile transceiver (1) comprises a prioritizing module (101) for assigning priority values to audio signals received by the receivers (16a, 16b, 16c, 17, 18, 19). The prioritizing module (101) is designed to assign priority values in accordance with priority values assigned to the receivers (16a, 16b, 16c, 17, 18, 19) that received the audio signal concerned and/or to signal identifiers contained in the received electrical or electromagnetic signals carrying the audio signal concerned.

Abstract: A method for noise suppression in wireless receivers or hearing aid devices comprising a receiver coil, wherein audible information is transmitted from a transmitter coil or loop in a wireless manner to said receiver coil, is disclosed and claimed. The method includes that the signal received by said receiver coil is analyzed by digital signal processing in the hearing frequency range and/or the speaking time range for discrete noise signals and other sound artifacts, and said noise signals and other sound artifacts are removed from said signal. This method allows to suppress noise that is introduced into the speech signal during the inductive transmission.
