Abstract

The invention provides a piezoelectric motor and an electronic device. The piezoelectric motor comprises a housing; the peripheral side of the elastic recovery piece is fixed on the inner wall of the shell; the first piezoelectric plate is attached to the elastic recovery piece, and the first piezoelectric plate is in a spiral shape; when the first piezoelectric plate is in a power-on state, the elastic recovery piece can reciprocate in the axial direction of the shell, and the first piezoelectric plate is stretched in the axial direction of the shell. The piezoelectric motor is improved, so that the piezoelectric motor has richer functions, the size of the piezoelectric motor can be controlled not to be increased too much, and the effect of miniaturization of electronic equipment is further achieved.

Description

technical field [0001] The present application belongs to the technical field of motors, and in particular, the present application relates to a piezoelectric motor and an electronic device. Background technique [0002] With the continuous development of science and technology and modern industry, the application range of motors is getting wider and wider. Although the traditional electromagnetic motor has high speed and high power, it uses the electromagnetic force between the rotor magnet and the stator coil to drive the rotor to rotate, not only the structure It is complicated and can cause the motor to fail when subjected to electromagnetic interference. For this reason, piezoelectric motors have gradually attracted widespread attention due to their fast response, simple structure, and immunity to electromagnetic interference. [0003] The vibration of the piezoelectric motor is caused by the expansion and contraction of the piezoelectric ceramic after being energized,...
