Abstract

A longitudinal-torsional hybrid transducer with a longitudinal resonance frequency tuning electric port was proposed. The longitudinal resonance frequency can be adjusted independently of the torsional one by changing the external electrical impedance. This new technique can be applied to ultrasonic processing tools and ultrasonic motors.
