Abstract
In a hands-free device which is particularly suited for automotive vehicles, the loudspeaker (20) is arranged in a housing (16) which is loosely seated on the belt and which is fixed with a mounting to the B-pillar near the ear. The microphone (30) is positioned within a microphone housing (18) which can be displaced on and fixed to the belt (10), and communicates via an infrared path with a circuit provided in the loudspeaker housing. An accumulator which powers the microphone circuit is charged via charging contacts (34, 36) between microphone housing and loudspeaker housing when the microphone housing (18) is pushed towards the loudspeaker housing (16). Power can be supplied via a cable from the car socket, and the signal transmission between free-hands device and mobile telephone takes place via a plug connection with the head-set jack of the telephone.
