Abstract: The invention relates to a method for detecting the status of a telephone receiver (H) for a communication terminal (EG), wherein the telephone receiver (H) is equipped with a microphone (M) and with a loudspeaker (LS). The loudspeaker (LS) of the telephone receiver (H) is used to output a defined tone signal, and this tone signal is simultaneously picked up again by means of the microphone (M) of the telephone receiver (H). The tone signal picked up is analysed, with at least one value for at least one parameter of the tone signal picked up being ascertained, and the at least one value is used to determine the status of the telephone receiver (H).

Abstract: A wideband telephone handset is provided with an acoustic converter The acoustic converter is preferably a wideband acoustic converter and the membrane rear volume of the acoustic converter in the rear wall of the housing, thereof comprises openings which open towards the outside of the acoustic converter and from which noise can escape. The rear housing part of the telephone handset includes inner walls forming a type of channel through which the space up to the housing of the telephone handset is sealed in a soundproof manner around the openings of the rear wall of the housing of the acoustic converter. The rear housing part of the telephone handset has openings through which the noise escaping from the rear of the acoustic converter and conducted via the walls of the rear housing part of the telephone handset can be emitted from the telephone handset.
