Magnetic head actuator having conductive fastening member electrically connecting upper and lower piezoelectric elements
Abstract:
An actuator includes a piezoelectric bimorph including a pair of piezoelectric elements and an intermediate electrode provided between the piezoelectric elements, a conductive fastening member for fastening fixed ends of the piezoelectric elements to a base having a ground potential, and a contact member to which a predetermined voltage is applied. The contact member is in contact with the intermediate electrode.
Abstract(Chinese):

致动器包括压电双压电晶片，其包括一对压电元件和设置在压电元件之间的中间电极，用于将压电元件的固定端紧固到具有接地电位的基座的导电紧固构件，以及接触构件， 施加电压。 接触构件与中间电极接触。
