Sonic & ultrasonic transducers are electro-mechanical or electro-acoustic converters.
They transform electric energy into vibrations, which are used to generate mechanical, acoustic or even thermal power. Sonic transducers operate at audible frequencies, while ultrasounds operate at 20kHz or above. Transducers are often reciprocal devices: Most transducers can operate as sensor or generator exploiting mecano-electric conversion
