ultrasonic generators can be divided into two categories: one is to generate ultrasonic waves electrically, and the other is to generate ultrasonic waves by mechanical means. electrical methods include piezoelectric type, magnetostrictive type and electric type; mechanical methods include galvin flute, liquid whistle and air stream whistle. the ultrasonic waves produced by them have different frequencies, powers, and sonic characteristics, and their uses are also different.
