Abstract

PURPOSE:To constitute a simple portable stereo audio device, by transmitting a received FM stereo broadcast and a stereo signal such as stereo audio tape in different frequencies from a main body and receiving the signals with a head phone. CONSTITUTION:The carrier waves with different frequencies are modulated with a stereo signal such as a received FM broadcast and a signal from a stereo tape and stereo disc and the result is transmitted 8 from an antenna 7 of a main body 2. This radio wave 8 is received and detected at a radio section 3 of a head phone 1 to apply left and right signals of the stereo signal to left and right head phones 4a and 4b respectively. Thus, a portable device can be constituted with a simple constitution without the need of any pilot signal.
