A basic acoustic levitator has two main parts -- a transducer, which is a vibrating surface that makes sound, and a reflector. Often, the transducer and reflector have concave surfaces to help focus the sound. michael strahan height weight shoe size

WebbIn physics the term “resonance” refers to the natural tendency of many objects to vibrate more vigorously at some frequencies than at others. The frequencies at which this occurs are called the object’s “resonance frequencies.”. In acoustics great use has been made of a particular kind of resonance, called air resonance.
