US 2020/0052186 A1 · PIEZOELECTRIC DRIVING DEVICE

Abstract

A piezoelectric driving device includes a vibration unit, a piezoelectric element, a signal transmission layer, and a plane unit. The piezoelectric element includes a first electrode and a second electrode electrically isolated from each other. The signal transmission layer includes a first conductive zone and a second conductive zone. The first electrode of the piezoelectric element is electrically connected to the first conductive zone of the signal transmission layer, and the second electrode of the piezoelectric element is electrically connected to the second conductive zone of the signal transmission layer. The plane unit has at least one hole. The piezoelectric element, the signal transmission layer, and the plane unit are located at one side of the vibration unit and are sequentially stacked together.
