Abstract
An improved ultrasonic cleaning system employs a plurality of electroacoustic transducers located at different positions on the wall surfaces of a tank containing a cleaning liquid in combination with a source of electrical power and a selective switching system. The switching system applies the electrical power selectively, sequentially and intermittently to any specified one or more of said plurality of electroacoustic transducers to achieve substantially increased cavitation intensity levels in the cleaning liquid and thereby greatly improves the cleaning efficiency of the inventive system as compared to the conventional ultrasonic cleaners which are in widespread use.
