Title:
PIEZOELECTRIC MOTOR, CAMERA MODULE, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/143651
Kind Code:
A1
Abstract:
Provided in the present application are a piezoelectric motor, a camera module, and an electronic device. The piezoelectric motor comprises a vibration exciter and a resonator. The resonator comprises a main body part and a pushing part. The main body part comprises a first central shaft, the main body part being distributed on two sides of the first central shaft, and the vibration exciter being fixed to the main body part; the pushing part is connected to the main body part and distributed on two sides of the first central shaft, and the pushing part is an asymmetrical structure with regard to the first central shaft; and the pushing part is used to push, under the excitation of the vibration exciter, a driven member to move. The technical solution of the present application uses piezoelectric drive technology and solves the problem of electromagnetic interference of conventional motors, and the image capture quality of the camera module and electronic device is better.
