The longitudinal-torsional composite transducer with slanting slots was studied. The equivalent circuit for the vibrational system was derived. The effect of the slanting angle of the slots on the resonance frequency of the vibrational system was analyzed. It is concluded that when the slanting angle of the slots was increased, the resonance frequency was decreased. Experimental results show that the measured frequencies are in good agreement with the predicted results.
