Abstract

PURPOSE: To enable long distance communication by allowing a reception piezo vibrator to receive and reproduce a propagated wave of a modulated ultrasonic wave formed through the installation of a pizeoelectric vibrator for sending a carrier frequency non-tuning corresponding to an output of a transmitter medium wave output.
CONSTITUTION: A transmitter T3 of a caller side modulates a proper high carrier frequency wave (medium wave) with an input signal being a voice signal or the like and sends the modulated wave from an antenna 2. A receiver R4 of a receiver side receives the wave and amplifies and outputs it. The relation of the transmission and reception adopted for this method is different from that employing only a radio wave, because an ultrasonic elastic wave is intervened through the piezo vibrator in addition to the electromagnetic wave for the transmission and reception. When a voice modulation sound wave is generated, if the piezo vibrator is in resonance with the carrier frequency signal of the radio wave, no modulated ultrasonic wave is obtained, Thus, the vibrator whose size is not tuned to the carrier wave frequency signal is provided. Finally, the system is formed by coupling between the two systems being the radio wave system and the ultrasonic wave communication system. Thus, the ultrasonic wave is transmitted through a shield such as a metallic net even when the radio wave is shielded by the shield.
