[0002] With the continuous updating and improvement of mobile terminal products, functions are constantly evolving, and people's requirements for photo and video recording are also constantly increasing. Optical image stabilization motors have also come into being. They solve the problem of poor image quality caused by shaking during the photo shooting process.

[0003] Existing anti-shake motors generally include a base, a frame and a carrier. A frame is arranged above the base, and a carrier is arranged inside the frame. The carrier is used to install the lens. The frame drives the carrier to move in the X-axis and Y-axis directions on the base to realize the anti-shake operation of the lens. The carrier moves in the Z-axis direction relative to the frame to realize the focusing operation of the lens.

[0004] When achieving movement in the X-axis and Y-axis directions, coils and magnets are usually arranged relative to each other, and the two generate a force to make the magnets and the frame move in two directions. In the prior art, the coils are usually arranged on a base, and they are powered by a circuit board on the base. In order to achieve movement in the X-axis and Y-axis directions, several coils are usually arranged, which makes the connection between each coil and the circuit board and the layout of the coils relatively complicated, increases the difficulty of layout, and restricts the structural simplicity design of the anti-shake motor.
