Classification Of Ultrasonic Transducers

An ultrasonic transducer is a device that converts signals of other energies into the required ultrasonic signals or energy. Or vice versa, a device that converts ultrasonic signals or energy into another form of signal or energy. Common acoustic transducers in life include speakers, speakers, microphones, whistles, and all musical instruments.
(1) According to materials and processes
There are many types of ultrasonic transducers, such as electroacoustic ultrasonic transducers (including piezoelectric transducers, magnetostrictive transducers, electric and electromagnetic transducers, and fluid dynamic transducers (including airflow-excited resonant whistles, vortex whistles, flutes, circular plate whistles, and reed whistles excited by fluid injection, etc.). The most commonly used ultrasonic transducers are now mainly piezoelectric transducers.
(2) According to function
Cleaning transducers, welding transducers, atomizing transducers, ranging transducers, flow velocity and flow transducers, communication transducers, interference transducers, noise detection transducers, imaging transducers, etc.
