CONSTITUTION: In a circuit of a transmitter, a microphone converts a voice of a person into an electric signal. An amplifier circuit amplifies a voice signal. An external input terminal circuit selectively inputs output signals of a recorder or a sound apparatus. A variable resistor circuit for adjusting volume varies the size of signals. A power amplifier amplifies signals to supply the signals to a power line through the variable resistor circuit. A switch supplies the signals to the power line connected to a lamp, and switches the signals. Direct current(DC) power necessary for the circuit of the transmitter is dropped through a transformer(T), and rectified through a bridge diode(BD). In a circuit of a receiver, DC power is turned to a predetermined DC voltage through a zener-diode connected to a solar battery in parallel. The DC voltage is supplied to a reference voltage generator generating a 3V-reference voltage. An alternating current(AC) signal is combined and amplified as an input of a pre-amplifier through a condenser. The amplified signal passes notch filters eliminating noise of 60Hz and 120Hz, and is transmitted through an earphone or a speaker driven by a power amplifier circuit. And a variable resistor circuit is configured to adjust the volume of a voice.
