Abstract

A new type of piezoceramic acoustic disk resonator with a radial exciting electric field is described. The resonator is a disk made from 6mm crystallographic material using two round concentric metal electrodes with a gap between them placed on one side of the disk. Models of a free resonator and a resonator loaded with a film of finite thickness are presented. The characteristics of different acoustic modes for resonators made of BPZT-3 piezoelectric ceramic are calculated for different widths of electrodes and the gaps between them.

具有径向激励电场的声谐振器

摘要

描述了一种具有径向激励电场的新型压电陶瓷声学圆盘谐振器。谐振器是一个圆盘，由 6 毫米晶体材料制成，使用两个圆形同心金属电极，它们之间有一个间隙，位于圆盘的一侧。给出了自由谐振器和加载有有限厚度薄膜的谐振器的模型。针对不同宽度的电极和电极间的间隙，计算了BPZT-3压电陶瓷谐振器不同声模式的特性。
