Acoustic levitation - Wikipedia
Acoustic levitation is a method for suspending matter in air against gravity using acoustic radiation pressure from high intensity sound waves. [1][2] It works on the same principles as acoustic tweezers by harnessing acoustic radiation forces.
How Acoustic Levitation Works - HowStuffWorks
2023年8月23日 · Acoustic levitation uses sound traveling through a fluid — usually a gas — to balance the force of gravity. On Earth, this can cause objects and materials to hover unsupported in the air. In space, it can hold objects steady so they don't move or drift.
