Abstract

PURPOSE: To extend the frequency region of elastic waves, by placing the zigzag type conductive constituent changing its folding width and the bias magnetic field applying means on the non-crystal magnetostriction elastic thin plate surface.
CONSTITUTION: The solenoid coil 3 is placed as the DC bias applying means toward lengthwise of the non-crystal magnetostriction thin plate 1. The zigzag type coil 2 is closed on the plane of the non-crystal magnetostriction elastic thin plate 1 or closely installed with other support, and the distance P is approximately made constant and the width w is changed along the lengthwise of it. Toward lengthwise, the signal magnetic field by the zigzag type coil 2 and the bias magnetic field by the solenoid coil 3 are fed, exciting elasitc magnetostriction in proportional to the constant of magnetostriction. The bias magnetic field improves the conversion efficiency of the transducer and controls the propagation speed of elastic distortion
