International ClassG10K 15/00 (20060101)AbstractAn apparatus is described for acoustically levitating an object within a chamber by the application of acoustic energy of a single frequency resonant mode, which enables smooth movement of the object and suppresses unwanted levitation modes that would urge the object to a different levitation position. A plunger forms one end of the chamber, and the frequency changes as the plunger moves. Acoustic energy is applied to opposite sides of the chamber, with the acoustic energy on opposite sides being substantially 180° out of phase. | |
