Piezoelectric motor, camera module, and electronic device

A camera module comprising a base, an optical structure, and a piezoelectric motor, wherein the piezoelectric motor comprises:

• a vibration exciter;
• and
• a resonator comprising a main body portion and a push portion, wherein:
• the main body portion comprises a first central axis, and the main body portion is distributed on two sides of the first central axis,
• the vibration exciter is fastened to the main body portion,
• the push portion is connected to the main body portion and distributed on the two sides of the first central axis, the push portion is of an asymmetrical structure with respect to the first central axis, and the push portion is configured to push, when excited by the vibration exciter, a driven member to move;
• and
• the resonator is fastened to the base, and the optical structure is fastened to the driven member, to move relative to the base when driven by the resonator.
