ABSTRACT:
A piezoelectric transducer comprising first and second members in axial alignment and spaced apart, the first and second members being mutually displaceable toward and away from each other, and a transducer assembly disposed between the first and second members. The assembly includes a stationary means (first member), a piezoelectric element facing the stationary means on its entire surface, and a force converting means (second member) for generating a transverse force in direction radially outward from a center axis, facing the piezoelectric element at entire surface. The stationary means, the piezoelectric element and the force converting means are contained sequentially between the first and the second member.
