Working Principle

1. Ultrasonic standing wave suspension is through the existence of a certain distance between the ultrasonic transmitting end and the reflecting end (or another transmitting end) (called the resonant cavity distance).
2. The transmitted wave and the reflected wave (or another sound wave) are continuously superimposed to eventually form a standing wave. The sound wave force on the object at the node of the standing wave overcomes the effect of gravity and finally achieves the effect of suspension.
