Acoustic levitation uses sound waves to counteract gravity, create standing waves, and then keep objects in air. In this paper, we will start with an introduction about acoustic levitation, its various types, introduction about different parts, their work in this project, and step-by-step process to make a working model of acoustic levitation. Acoustic levitation was discovered a century ago. At that time, it was limited to levitating small objects, but now it can be useful to levitate objects larger than the acoustic wavelength. It is helpful to trap an assortment of materials like fluids, solids, and living things like, holding insects or other very delicate living things allows us to effectively study them under a magnifying lens without contacting them. It’s useful in many other places like the mobile industry, packaging industry, etc.
