[0128] The driving assembly 300 includes a driving part 301 and a control unit 302. The driving part 301 generates a driving force and is fixedly connected to the movable part 100, as described below. The control unit 302 outputs a driving signal to the driving part 301 and is fixedly connected to the fixing element 670.

[0130] A first coil 310, a first magnetic element 320, a second coil 330, a second magnetic element 340, and a fourth coil 370 are formed as a group and are respectively disposed on two opposite sides of the movable portion 100.

[0132] The first magnetic element 320 is disposed on the frame 120 and has a first magnetic element surface 321 . The first magnetic element surface 321 faces the first coil 310 .

[0133] The electromagnetic driving force generated between the first magnetic element 320 and the first coil 310 causes the first magnetic element 320 to move relative to the first coil 310, thereby driving the frame 120 to move relative to the base 220, and the frame 120 drives the movement of the main body 110, the fixed element 670, and the optical element 10. Therefore, the electromagnetic driving force generated between the first magnetic element 320 and the first coil 310 can drive the movable part 100 to move relative to the fixed part 200.
