1. An optical element driving mechanism, comprising:
a fixed part comprising a bottom;
a movable part movable relative to the fixed part, holding an optical element with an optical axis;
a first driving assembly, comprising:
at least two first magnetic elements; and
at least two first coils, wherein one of the at least two first magnetic elements and one of the at least two first coils are arranged along a first direction, the at least two first magnetic elements are arranged along a second direction, the at least two first coils are also arranged along the second direction, and the first driving assembly drives the movable part to move relative to the fixed part along
the second direction;
a second driving assembly, comprising:
a second magnetic element; and
a second coil, wherein the second magnetic element and the second coil are arranged along the first direction, the second driving assembly drives the movable part to move relative to the fixed part along a third direction, and the first direction, the second direction, and the third direction are different; and
a magnetic-permeable element comprising a first portion corresponding to the first driving assembly and a second portion corresponding to the second driving assembly, and both the first portion and the second portion are parallel to the optical axis,
wherein when viewed in the optical axis, the first driving assembly at least partially overlaps the second driving assembly,
wherein when viewed in the second direction, the bottom is disposed below the first driving assembly and the second driving assembly, and
wherein the second magnetic element or the second coil is sandwiched between the at least two first magnetic elements that are spaced apart in the second direction, or between the at least two first coils that are spaced apart in the second direction.
