Piezoelectric transformer having improved electrode arrangement |
摘要 |
A long relatively thin rectangular body of piezoelectric material is divided into driving and driven regions in a longitudinal direction thereof. Two electrodes are applied respectively to two major surfaces of the driving region which is polarized in a thickness direction of the driving region. Another two electrodes are formed on one major surface of the driven region. Each of the two electrodes applied to the driven region has a plurality of finger-like portions which extend in the longitudinal direction. The finger-like portions of formed on the driven region are arranged in an interdigital manner. The driven region has a plurality of regions which are defined by adjacent finger-like portions and which are polarized in a direction perpendicular to the longitudinal direction.
