摘要：
A piezoelectric transducer having plural piezoelectric transducer elements which can generate mechanical vibrations converging substantially on one point. The transducer is formed to control the convergent point by insulating piezoelectric transducer elements mechanically, arranging them concentrically and driving them independently and separately from each other.
