This is a mini ultrasonic levitation gadget that levitates foam balls. The device consists of 1 microcontroller, 1 driver chip and 2 ultrasonic probes, with a simple assembly kit, you can operate it within minutes. Suspension modules are made of high-quality materials for long-term use. Small size, easy to carry. With power indicator light and ultrasonic suspension indicator light, you can know the working status of the product by observing the indicator light. Mainly for students or DIY electronics enthusiasts to learn ultrasonic standing wave levitation. Controlling the up and down movement of suspended objects is currently not supported.

Working principle:
Ultrasonic standing wave levitation is based on the fact that there is a certain distance (called the resonant cavity distance) between the ultrasonic transmitting end and the reflecting end (or another transmitting end), and the transmitting wave and the reflected wave are superimposed continuously. The reflected wave (or other sound wave) eventually forms a standing wave. The acoustic wave force received by the object at the standing wave node overcomes the effect of gravity, and finally achieves the effect of suspension.
