The function of ultrasonic transducer is ()

A device that converts electromagnetic energy into mechanical energy and acoustic energy. The ultrasonic transducer is made of piezoelectric ceramics or other magnetostrictive materials. Common ultrasonic cleaners, ultrasonic atomizers and ultrasonic probes are all examples of the application of ultrasonic transducers. The function of ultrasonic transducer is to convert the input electric power into mechanical power (that is, ultrasonic wave) and then transmit it, while consuming a small part of its own power.
