METHOD AND MEANS FOR REDUCING THE RESONANT FREQUENCY OF A PIEZOELECTRIC TRANSDUCER

摘要

The resonant frequency of a conventional piezoelectric transducer having predetermined dimensions and a fundamental nodal diameter is reduced while maintaining the overall predetermined diameter and fundamental nodal diameter of the transducer. A method of reducing the resonant frequency of a conventional piezoelectric transducer includes the step of radially slotting the substrate of the transducer.
