Abstract

Piezoelectric transducers are mounted on the end resonators carrying out longitudinal oscillations. Rod-shaped round parallel resonators carry out torsional oscillations. The two end resonators are installed on one side of the rod-shaped resonators at a right angle to them and parallel to each other. One of the end resonators is coupled to every other rod resonator and the other end resonator to the remaining by tangential links. Both end resonators are coupled to the farthest rod resonator.
