Optical member driving system

1. An optical member driving system, comprising:

a first driving assembly, configured to move a first optical member and comprising:

a base;

a frame, movably connected to the base;

a first magnet, disposed on the base; and

a first coil, disposed on the frame, wherein when a first current is applied to the first coil, a first magnetic force is generated between the first magnet and the first coil to move the frame relative to the base; and

a second driving assembly, configured to move a second optical member, wherein a first optical axis of the first optical member, the first magnet, and a second optical axis of the second optical member are arranged along a first direction, and the first magnet is disposed between the first optical axis and the second optical axis.

2. The optical member driving system as claimed in claim 1 , wherein the first direction is perpendicular to the first optical axis and the second optical axis.

3. The optical member driving system as claimed in claim 2 , wherein the first driving assembly further comprises a first optical member holder, a second coil disposed on the first optical member holder, and a second magnet corresponding to the second coil, wherein when a second current is applied to the second coil, the first optical member holder moves relative to the frame along a second direction perpendicular to the first direction.

4. The optical member driving system as claimed in claim 3 , wherein when viewed along a direction perpendicular to the first optical axis of the first optical member, the first coil and the second magnet at least partially overlap.

5. The optical member driving system as claimed in claim 3 , wherein at least one of the first and second magnets is a multi-polar magnet.

6. The optical member driving system as claimed in claim 1 , wherein the first driving assembly further comprises a third magnet and a third coil, and the first axis is disposed between the third magnet and the second axis.

7. The optical member driving system as claimed in claim 6 , wherein the first coil and the third magnet respectively have a bottom surface corresponding to the first magnet and the third coil, and the bottom surfaces of the first coil and the third magnet are aligned with each other.

8. The optical member driving system as claimed in claim 6 , wherein the first magnet and the third coil respectively have a top surface corresponding to the first coil and the third magnet, and the top surfaces of the first magnet and the third coil are aligned with each other.
