Product Details
2. This levitator in the air at a frequency of 40KHZ operation, can capture the density diameter of 2-3MM quality of light objects, such as foam balls, ants and other tiny items in the air for a long time to stabilize the levitation, the motherboard is slightly warm;
3. The circuit mainly consists of 1 microcontroller, 1 driver chip and 2 ultrasonic transmitter heads;
4. Simple operation, use tweezers to hold the small foam ball, gently put the foam ball to between the 2 ultrasonic probes, the foam ball will levitate;
5. Mainly used for learning to understand the ultrasonic standing wave levitation, suitable for students or DIY electronics enthusiasts to learn ultrasonic levitation standing wave.
Power input: DC5V (0.5-1A)
Frequency: 40KHZ
Operating Temperature: -25℃～85℃
Appearance size (finished): length 45mm * width 44mm * height 66mm
Working principle: ultrasonic standing wave levitation is through the ultrasonic transmitting end and transmitting end (or another transmitting end) the existence of a certain distance (called the resonant cavity distance), the emitted wave and the reflected wave (or another acoustic wave) is constantly superimposed, and eventually formed standing wave, the acoustic wave force at the standing wave node of the object by the acoustic wave force to overcome the role of gravity, and ultimately to achieve the effect of levitation.
How to play: use tweezers to hold the small foam ball, gently put the foam ball to between the 2 ultrasonic probes, the foam ball will levitate.
