ABSTRACT:
An ultrasonic oscillating device comprising a base plate and an ultrasonic transducer attached to the base plate. The thickness of the base plate is an integer multiple of approximately a half-wavelength of an oscillation of the base plate in the direction of its thickness under a driving frequency. The base plate may be a quadrilateral such as a square and a rectangle with a length of one side of the quadrilateral being at least a quarter-wavelength of the oscillation. The base plate may be a circle with a length of a diameter of the circle being at least a quarter-wavelength of the oscillation. An ultrasonic washing apparatus comprising a cleaning tank, an ultrasonic multi-frequency oscillator, and the ultrasonic oscillating device is also provided.
