It has two piezoelectric wafers and a resonance plate. When the pulse signal is applied at its two poles and its frequency is equal to the natural oscillation frequency of the piezoelectric wafer, the piezoelectric wafer will resonate and drive the resonance plate to vibrate to produce ultrasonic wave. On the contrary, if no voltage is applied between the two electrodes, when the resonance plate receives ultrasonic wave, The piezoelectric wafer will be compressed for vibration and the mechanical energy will be converted into electrical signals.
