1. A magnetic driving assembly, comprising:
a frame body, wherein an inner side of the frame body is configured to arrange a lens bracket;
a plurality of magnetic pieces, which are disposed on the frame body;
a coil carrier plate, which is disposed to be separated from the frame body and is configured to arrange an image sensor; and
a plurality of coils, which are disposed to correspond to the plurality of magnetic pieces; wherein each of two ends of the coil carrier plate in a first direction is provided with one of the plurality of coils configured to drive the coil carrier plate to linearly move in the first direction, each of two ends of the coil carrier plate in a second direction is provided with two coils of the plurality of coils configured to drive the coil carrier plate selectively to move linearly in the second direction or rotate around a third direction, each of two ends of the frame body in the second direction is provided with one of the plurality of magnetic pieces corresponding to the two coils on the respective end; wherein each magnetic piece on the two ends of the frame body in the second direction has two poles in the second direction, and the two coils on each of the two ends of the coil carrier plate in the second direction are arranged side by side in the first direction and adjacent in one-to-one correspondence to two ends of a respective one of the plurality of magnetic pieces in the first direction, respectively; wherein, the first direction, the second direction and the third direction are perpendicular to one another, and the third direction is perpendicular to the coil carrier plate.
