Radio channel i.e. center channel, transmitting and receiving device for use in public radio field, has housings respectively generating stereo and mono signals, and signals, where signals are received in respective channels of headphone

摘要

The device has five housings respectively generating five white noise signals e.g. two stereo signals, mono signal, and two signals at same frequency. The signals are passed via an antenna and transferred on bandwidth of radio parabola at a frequency of 38 kilohertz. The signals are projected on a satellite antenna in the form of light and are reflected from the antenna at a receiving frequency of 19 kilohertz. The stereo signals, mono signal and the signals are respectively received in right and left channels, center channel, center rear channel, and center front channel of the headphone.
