Acoustic Levitation Model Ultrasonic Levitation or Suspension

Acoustic Levitation Model Ultrasonic Levitation or Suspension

Acoustic Levitation Model Ultrasonic Levitation or SuspensionFeatures:.This kit is a DY learning kit, specifically for students and electronic enthusiasts to learn. It is very meaningful for teaching..This kit has spare parts and assembled. Customers who buy spare parts need to have a certain circuit basis and soldering ability, electric iron, soldering tin, and preferably a hot meltgun to fix the sensor..Human ears cannot hear the 40KHZ sound, so the device can not hear the sound theoretically..Suspended small bubbles are relatively easy to operate, and water droplets and small insects are not easy to suspend. It is necessary to grasp the balance of standing waves to stabilize the suspension..Acoustic Levitator:Acoustic levitation is an interesting phenomenon: it takes advantage of the fact that sound waves carry mechanical energy in order to exert force on an object. In this case, that force is directed against gravity to make the object levitate. Unlike magnetic levitation, acoustic levitation can be used on a wide range of materials (even insects), though it is a weaker force.ļ¼ˆThis is an unassembled kit .ļ¼‰.Package List: 3D-printed TinyLev x1; Arduino Nano with mini USB cable x1; 10mm 40kHz transducers x76; L298N Dual Motor Drive Board x1; DC power adaptor 9V x1; Power switch X1; DC female connector(5.5 X2.1mm) x1; Button x3; Some Jumper wires; Some Black and red wire; Some Exposed wire; 7.
