Descripersion:

An ultrasonic transducer is a device that converts electrical ultrasonic energy into ultrasound energy, or sound waves above the normal range of human hearing. While technically a dog whistle is an ultrasonic transducer that converts ultrasonic mechanical energy in the form of air pressure into ultrasonic sound waves, the term is more apt to be used to refer to ultrasonic piezoelectric transducers that convert electrical energy into ultrasound.

Piezoelectric crystals have the property of changing size when a voltage is applied, thus applying an alternating current (AC) across them causes them to oscillate at very high frequencies, thus producing very high ultrasonic frequency sound waves.

The location at which a ultrasonic transducer focuses the ultrasound can be determined by the active ultrasonic transducer area and shape, the ultrasound frequency, and the ultrasonic sound velocity of the propagation medium.
