Abstract

PURPOSE:To reduce dimensions of the resonantor to make the piezoelectric porcelain plate small-size, by utilizing frequency rise type energy shutting-in of width longitudinal oscillation of the piezoelectric longitudinal effect. CONSTITUTION:Driving electrodes 2 and 2' are formed in the center of piezoelectric porcelain rectangular plate 1 (width H, length l0 and thickness t) polarized in the breadthwise direction. Peripheral electrodes 3 and 3' are provided on all of or almost all of left and right end parts except the center in the longitudinal direction and are used as lead line leading-out terminals 4 and 4'. As a result, the cutoff frequency in the center becomes higher than that in peripheral parts, and frequency rise type energy shutting-in of longitudinal effect width longitudinal oscillation is realized in the center driving electrode part.
