This is a mini ultrasonic levitation device that can levitate foam balls. The device consists of a single-chip microcomputer, a driver chip and two ultrasonic probes.
Mainly used for students or DIY electronic engineers to learn about levitation with standing ultrasonic waves.
There is a certain distance (resonant cavity distance) between the ultrasonic transmitting end and the reflecting or other transmitting end. The transmitted wave and the reflected wave (or another sound wave) are continuously superimposed and form a standing wave. The force of the sound wave on the object at the node of the standing wave overcomes the effect of gravity and finally achieves the levitation effect.
