Filed: 1987-03-20
Abstract: PURPOSE:To remove the mixing of sound due to multiplex broadcast and monaural and to realize broadcasting with resulting high sound definition, by switching a mode at the time of deciding the travel state of a vehicle by a decision means. CONSTITUTION:In a state where the mode is set at a double mode or a stereo mode to receive sound multiplex broadcast by remote control switches 6 and 7, a microcomputer 5 continues the double mode or the stereo mode if the speed of the vehicle is set at less than 1km/h by a signal from a speed sensor 10 when receiving the sound multiplex broadcast, and outputs a main and a sub channel signals of an FM demodulation circuit 3 as they are as voice signals. Also, the microcomputer 5, when judging the speed as the one exceeding 1km/h, that is the vehicle is in travel by the signal from the speed sensor 10, sets the mode at a monaural mode compulsorily by controlling a sound multiplex switching circuit 4, and invalidates the sub channel signal of the FM demodulation circuit 3, and outputs the main channel signal as the voice signal. In such a way, it is possible to set the mode at the monaural mode and to realize the broadcasting with resulting high definition in which no mixing of sound exists.
