Document Type and Number:
WIPO Patent Application WO/2022/067919
Kind Code:
A1
Abstract:
The present application provides a linear motor and an electronic device. The linear motor comprises a drive assembly, an oscillator assembly, an elastic support member for supporting the oscillator assembly, and a housing having an accommodation space. The oscillator assembly comprises a mass block provided with a mounting cavity and a magnetic steel group provided in the mounting cavity; the mounting cavity comprises a first mounting recess and a second mounting recess; the magnetic steel group comprises a first magnetic steel and a second magnetic steel; the first magnetic steel matches the first mounting recess, and the second magnetic steel matches the second mounting recess; the orthographic projection of the second magnetic steel on the first magnetic steel in a vibration direction is at least partially located outside the first magnetic steel. According to the linear motor in the present embodiment, the first mounting recess and the second mounting recess staggered with each other are provided in the mounting cavity on the mass block, such that each magnetic steel in the magnetic steel group is mounted at a corresponding position, and can also be positioned by a corresponding mounting recess, thereby effectively improving the assembly consistency of the linear motor.
