Sonic-Pump LevitatorAudiospeaker drives gas and rapidly responds to corrective signals. Audiospeaker drives gas through plate opening and columnar outlets to levitate sphere. Exhaust flow dominated by gas momentum and essentially parallel to axis of outlets. With appropriate scaling up of hardware, sonic pump can function as levitator for containerless processing of more massive specimens of higher densities and of different materials.
