Abstract
(EN)
Provided is an actuator comprising a piezoelectric element and a vibration plate. The piezoelectric element has a bonding face. The vibration plate is bonded to the bonding face of the piezoelectric element and vibrates according to deformation or displacement of the piezoelectric element. The center of the bonding face of the piezoelectric element is bonded so as to be positioned inside an area in which a transmission unit is disposed on the vibration plate.
(FR)
L'invention concerne un actionneur comprenant un élément piézoélectrique et une plaque de vibration. L’élément piézoélectrique comprend une face de liaison. La plaque de vibration est liée à la face de liaison de l'élément piézoélectrique et vibre selon la déformation ou le déplacement de l'élément piézoélectrique. Le centre de la face de liaison de l'élément piézoélectrique est lié de manière à être positionné à l'intérieur d'une zone dans laquelle une unité de transmission est disposée sur la plaque de vibration.
(JA)
アクチュエータは、圧電素子と、振動板とを備えている。圧電素子は接合面を有する。振動板は、圧電素子の接合面が接合され、圧電素子の変形又は変位に応じて振動する。圧電素子の接合面の中心は、振動板において伝達部が配置される領域内の位置になるように接合される。
