Description
Features:
This is a small ultrasonic levitation device that suspends foam balls;
The levitator operates at a frequency of 40KHZ in the air, and can capture light objects with a density of 2-3MM in diameter, such as foam balls, ants and other tiny objects that are suspended in the air for a long time, and the main board is slightly heated;
The circuit is mainly composed of 1 single-chip microcomputer, 1 driver chip and 2 ultrasonic transmitters;
It is mainly used to learn about ultrasonic standing wave levitation.
It is suitable for students or DIY electronics enthusiasts to learn ultrasonic levitation standing waves.
Product parameters:
Power input: DC 12V (0.5-1A)
Frequency: 40KHZ
Working temperature: -25℃～85℃
Appearance size (finished product): length 44 mm * width 40 mm * height 66 mm
Working principle: Ultrasonic standing wave levitation is through the existence of a certain distance between the ultrasonic transmitter and the transmitter (or another transmitter) (called the resonant cavity distance), and the continuous superposition of the transmitted wave and the reflected wave (or another sound wave), and finally forms Standing wave, the acoustic wave force received by the object at the node of the standing wave overcomes the effect of gravity, and finally achieves the effect of suspension.
