ABSTRACT:
A piezoelectric transducer having electrodes formed on both surfaces has a piezoelectric base molded as a curved plate which can converge sound fields of acoustic waves at an arbitrary point and which can reduce noise or reverberation in a lateral direction which otherwise occur due to unnecessary vibration. At least one of the electrodes is divided concentrically. A material having a small electromechanical coupling factor K.sub.p in the lateral direction is used for the piezoelectric material, preferably porous PZT.
