Abstract

PURPOSE:To constitute the converter which can realize modulation efficiently, by providing the filter function and the function as the amplitude modulator on the same piezolelectric substance, in the converter converting electric signal into ultrasonic waves or untrasonic waves into electric signals. CONSTITUTION:At the center surface of the thin plate shape piezoelectric substance 1, the unidirectional transducer 10 is formed, the input transducer 11 forming a pair of single phase reed screen shape electrodes interdigitally is provided at one side of the transducer 10, and the output transducer 12 forming a pair of single phase reed screen shape electrodes interdigitally in provided at another side. The ultrasonic wave converter is constituted by forming the reed screen shape electrodes 23,24 on one side of the transducer 10, forming the surface electrode 22 corresponding to the electrodes 23,24 on another surface, and connecting the means 5 connecting a load variably between the electrodes 23,24 and the surface electrode 22.
