Sound Waves levitates a small foam with speakers
*Overview of the video*
This is an acoustic portable levitation device I made that uses ultrasonic transducers (speakers) producing 40khz to levitate objects. Since it is above the human hearing, I am not able to hear it in person. However, some microphones can pick up some sound. That's the sound you hear in the video. I also do not feel anything. It can't hold heavy objects. The particles I am using are pieces of foam for now, but it looks awesome!
*Explanation of how it works*
The transducer arrays are split into 4 sections with different phases. The Arduino Nano sends out 40khz to the arrays and the transducers are amplified by the motor driver. The buttons can move the particle up/down and re-center by changing the phases. This turns it into a "Tractor Beam". The device is ran by 2 18650 batteries.
*Extra*
This project and video is made by me (David's Workshop). If you decide to feature this video, please email me if you need extra footage. The video I uploaded has multiple clips of the same project, because those were the best clips that went viral on my TikTok, but the video clips are all raw.
