Abstract

PURPOSE:To secure listening of the explanation at the zoo or the like through the car radio by oscillating the aural magnetic wave from the transmission loop of the magnetic wave signal transmission unit and then listening the aural magnetic wave via the receiver of the general broadcast band. CONSTITUTION:Transmission loop 3 is connected to magnetic wave transmitter A, and the aural magnetic wave is oscillated through loop 3 wired along the car road. Adaptor B to receive the aural magnetic wave consists of reception coil 4, aural amplifier 5, frequency oscillator 6, modulator 7 and antenna 8 each. And the electric wave is oscillated by giving the amplitude modulation to the aural magnetic wave into the frequency which is selected previously. This adaptor B can be carried freely into the car going round within the zoo, and the modulated wave oscillated through antenna 8 is recieved at radio C attached to the car.
