At this time, the first bracket 300 , the second bracket 400 and the lens assembly move relative to the module housing 100 as a whole.

It should be noted that when any one of the first coil group 520 , the second coil group 530 and the third coil group 540 is energized, the essence is to drive the lens assembly to move.

Compensation is performed, and then the anti-shake function of the camera module can be realized, so as to improve the shooting quality of the camera module.

In addition, when the direction of the current passing through the coil group is changed, the direction of the ampere force is changed, thereby making the lens assembly change direction flexibly, and the anti-shake effect is better.
