ABSTRACT:
A radial acoustic driver uses to generate higher amplitude of pressure fluctuation with radial type standing wave. The radial acoustic driver includes a cyclic type resonance tube which is filled with a working fluid inside, and a ring type electricity-acoustic energy transducer that is inside the cyclic type resonance tube for generating a radial acoustic wave when receiving electricity.
