International ClassH04B 001/00Foreign Application Priority Data1996-05-17 DEAbstractA radio receiver with an integrated telephone device (1) is proposed, which is used for switching of loudspeakers (20, 21, 22, 23) between radio reception and telephone reception. In the telephone mode the loudspeakers (20, . . . , 23), which can be connected to the radio receiver, are switched to telephone reception, and when a preset signal is received by the radio receiver, preferably an information signal for traffic reports which has been modulated on a 57 kHz auxiliary carrier, the loudspeakers (20, . . . , 23) are partially switched over to radio reception. In the radio reception mode the loudspeakers (20, . . . 23), which can be connected to the radio receiver, are switched to radio reception, and in case of a loop allocation in the telephone device (1) for receiving an incoming and/or outgoing call, the loudspeakers (20, . . . , 23) are at least partially switched over to telephone reception. Switching of the loudspeakers (20, . . . , 23) can take place by means of a control circuit; (5), which additionally is used for acoustically processing audio signals. Various preset allocations of the loudspeakers (20, . . . , 23) to telephone and radio signals can be selected by a user by means of an operating unit (30) connected with the control circuit (5). | |
