Problems solved by technology

[0005] However, the current lens-translation voice coil motor usually contains many parts, and the structure is complex, which is not conducive to production, and it is difficult to improve reliability and reduce cost
Moreover, the magnets in the lens-translation voice coil motor are usually located in the movable structure, so they are easily affected by external magnetic fields and affect the performance of the voice coil motor

Abstract

The invention provides an anti-magnetic interference translational optical anti-vibration voice coil motor, which includes a base, a shrapnel, a lens carrier, at least three magnet groups and a casing. The base, the shell and the magnet group are connected together to form a fixed structure. The magnet groups are arranged inside the casing; each magnet group includes a first magnet and a second magnet; the second magnet is stacked on the first magnet, and the directions of the magnetic fields of the first magnet and the second magnet are opposite. The lens carrier includes a body and coils arranged on the body; the number of the coils is the same as that of the magnet groups; the coils and the magnet groups are arranged opposite to each other. The elastic piece is connected to the lens carrier and one of the first magnet and the second magnet. By arranging the magnets in a fixed structure, the performance of the anti-magnetic interference translational optical anti-vibration voice coil motor is not easily affected by the external magnetic field, so it has a certain anti-magnetic interference performance.

Description

technical field [0001] The invention relates to a voice coil motor in electronic equipment accessories, in particular to an anti-magnetic interference translational optical anti-vibration voice coil motor and an assembly method thereof. Background technique [0002] At present, miniature optical image stabilization voice coil motors have been widely used in high-end mobile phones, which can effectively reduce the chance of blurry photos taken in low-light environments and disturbing shaking in videos. However, compared with general AF motors, the design of anti-shake voice coil motors is more complicated, and the production yield and efficiency are lower. Therefore, anti-shake voice coil motors are mainly used in high-end mobile phones, but not in mid-range and low-end mobile phones. Popularity has greatly affected the experience of mobile terminal users such as mobile phone users. [0003] Miniature optical image stabilization voice coil motors can be divided into three ca...
