Title:
DRIVER AND MANUFACTURING METHOD THEREFOR, DRIVING APPARATUS, CAMERA MODULE, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/051118
Kind Code:
A1
Abstract:
The present application provides a driver and a manufacturing method therefor, a driving apparatus, a camera module, and an electronic device. The driver comprises a plurality of stacked piezoelectric bodies and an abutting member arranged on one side of the piezoelectric bodies; each of the piezoelectric bodies comprises a first electrode layer and a second electrode layer arranged opposite to each other; two adjacent piezoelectric bodies are bonded by means of the first electrode layers on the two piezoelectric bodies, and/or two adjacent piezoelectric bodies are bonded by means of the second electrode layers on the two piezoelectric bodies. According to the driver and the manufacturing method therefor, the driving apparatus, the camera module, and the electronic device provided in the present application, the input power of the driver can be improved by providing a stacked structure of the plurality of piezoelectric bodies, so that a larger driving force is obtained. Two adjacent piezoelectric bodies are directly bonded by means of the first electrode layers and/or the second electrode layers, so that the overall thickness of the driver can be further reduced to obtain a larger driving force and achieve large-stroke driving.
