The corresponding hole structure (not shown) is disposed between the through hole 32 and the lens to lock the lens in the through hole. In the case 32, the drive coil 40 (second drive coil) is wound around the outer peripheral surface of the lens holder 30.

In the present embodiment, the lens carrier 30 and the lens therein are movably disposed within the frame 50. More specifically, the lens holder 30 can be suspended from the center of the frame 50 by the upper reed 70 and the lower reed 72 made of metal. When a current is applied to the aforementioned driving coil 40, the magnetic field that can transmit and drive the magnet 60 acts, and generates an electromagnetic force to drive the lens holder 30 and the lens to move in the Z-axis direction relative to the frame. . For example, the foregoing four driving magnets 60 (magnetic elements) may include at least one multipole magnet for sensing with the driving coil 40 to drive the lens carrier 30 and the lens to move in the optical axis O direction.

In the present embodiment, the magnetic elements M1 and M2 do not overlap each other as viewed from the X-axis direction.

Based on the above structural design, as shown in FIG. 8, the influence of the magnetic field generated between the adjacent magnetic elements M1 and M2 of the two lens driving modules can be weakened, thereby improving the two lens driving modules in the dual lens camera system.

However, in order to overcome the problem that the driving force is insufficient due to the reduction of the magnetic element M in the first lens driving module, as shown in FIG. 10, it may be added to the second side F2 in the first lens driving module. The width, volume or weight of the magnetic component M is used to improve the overall driving force of the first lens driving module, wherein the magnetic component M located on the second side F2 can be a magnet, and the second side F2 Relative to the first side F1.

Moreover, in order to avoid the stability of the first lens driving module on the left side of FIG. 10 due to the weight imbalance, a non-magnetic coupling may be disposed on the first side F1 of the first lens driving module. The weight W (as shown in FIG. 11) is made to correspond to the magnetic element M on the second side F2 to maintain the overall weight balance of the first lens driving module.

In this way, not only the moving distance of the lens carrier 30 in the Z-axis direction but also the thickness of the first and second lens driving modules in the Z-axis direction can be effectively reduced, thereby achieving the purpose of miniaturization of the mechanism.
