ELECTROACOUSTIC TRANSDUCER

摘要

An electroacoustic transducer comprises a piezoelectric cell and an oscillator. Two piezoelectric cells are introduced to the transducer. Two piezoelectric cells are connected to the first piezoelectric cell by electrodes of opposite polarity; said piezoelectric cells are shifted relative to the first electrode. A connection point of the piezoelectric cells is connected to a common wire. The second electrodes of piezoelectric cells are connected to a signaling wire of the oscillator.
