What Is an Ultrasonic Transducer?

An ultrasonic transducer is a device that produces sound at a frequency higher than the range of the human ear. Various technologies fall under this category. These technologies also have practical applications, notably in the medical field.

Function

Some ultrasonic transducers create sound by using an electric current to create vibrations. These vibrations can be fine-tuned into ultrasonic frequencies.These transducers function under the piezoelectric effect.

Process

Ultrasonic transducers may function under the magnetostrictive effect. They use magnetic fields to to create the mechanical energy used to create the sounds.

Significance

Ultrasonic transducers have an almost infinite potential for application. The most prevalent use of the technology is in medical imaging, such as that used to view fetuses inside the womb.
