Resonant cylindrically shaped ultrasonic wave generator

摘要

The ultrasonic wave generator incorporates an ultrasonic-frequency vibratory member of cylindrical shape from which ultrasonic waves are produced, and the vibratory member is securely connected of its outer cylindrical surface to the mechanical vibration output end of a metallic block amplifier member which in turn is connected to an ultrasonic electromechanical transducer of the piezoelectric type, etc. The cylindrically shaped vibratory member effects a motion of flexural vibrations in the radial direction throughout its extensive areas, producing large-amplitude ultrasonic waves.
