Piezoelectric ultrasonic transducer is an important part of ultrasonic cleaners, the transducers convert electrical energy from ultrasonic generator to ultrasonic waves. Ultrasonic transducers are used to convert electrical energy to acoustic energy, do something useful with the acoustic energy, and convert the acoustic energy back into electrical energy. The conversion of electrical energy to acoustic (and vice versa) is a function of the piezoelectric element.
