DESCRIPTION
This is a mini ultrasonic levitation device that can suspend foam balls. The device consists of a single chip microcomputer, a driver chip and two ultrasonic probes. Mainly used for students or DIY electronics enthusiasts to learn about ultrasonic standing wave suspension. Controlling the up and down movement of suspended objects is not currently supported.
Working principle:
Ultrasonic standing wave suspension is that there is a certain distance between the ultrasonic transmitting end and the reflecting end (or another transmitting end) (called the resonant cavity distance), and the transmitted wave and the reflected wave (or another acoustic wave) are continuously superimposed to form a standing wave. The acoustic wave force on the object at the standing wave node overcomes the effect of gravity and finally achieves the effect of suspension.
Feature:
Power input: DC12V;
Appearance size: 40*40*70mm;
Weight: 26g.
