Inventor: WATABE YOSHIYUKI
IPC: H01L41/09
Filed: 2000-04-07
Abstract: PROBLEM TO BE SOLVED: To provide a piezoelectric transformer which can reduce irregularity of element due to supporting. SOLUTION: Central electrodes 16, 18 are divided in the transmission direction of mechanical vibration, and protrusions 12, 14 are arranged at laterally symmetric positions between the central electrodes. A piezoelectric member 10 is fixed and retained with the protrusions 12, 14. Consequently, the piezoelectric member 10 is not displaced at the central part and is in a state of λ/2 drive for which the displacement of both ends is the largest. Hence, the length of the piezoelectric member 10 may be half the length of the piezoelectric member of λ drive. The piezoelectric member 10 is made laterally symmetric, with respect to the protrusions 12, 14 of fixed points as the center. Since the retaining points are positioned by the protrusions 12, 14, irregularities of in the characteristics of the element due to supporting is reduced.
