Title:
PIEZOOTRANSDUCER AND METHOD OF REDUCING ITS RESONANCE FREQUENCY
Document Type and Number:
Japanese Patent JPS5443718
Kind Code:
A
Abstract:
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.
