发明名称 SONIC TRANSDUCER
摘要 <p>A sonic transducer incorporating a rigid plate-like transmitting member coupled to electromechanical compression wave generating means such as a piezoelectric crystal for transmitting sonic energy in a medium. The transmitting means is damped to prevent ringing, and the transducer is particularly responsive to the high frequency audio spectrum.</p>
