Abstract: An optical mechanism is provided. The optical mechanism includes a fixed member, a movable member, an optical element, a first sensing magnet and a first sensing element, wherein the movable member is movably connected to the fixed member, and the optical element is disposed on the movable member. The first sensing magnet corresponds to the optical element and has a first magnetic polar direction. The first sensing element corresponds to the first sensing magnet for detecting the rotation of the first sensing magnet around a first axis direction relative to the fixed member, wherein the first axis is perpendicular to the first magnetic polar direction.

Abstract: A driving module is provided. The driving module includes a fixed portion, a movable portion movably connected to the fixed portion and used to hold an optical element having an optical axis, a driving assembly for driving the movable portion to move relative to the fixed portion, and a circuit assembly electrically connected to the driving assembly. The circuit assembly includes a first segment, a second segment, and a third segment. The first segment is resilient, plate-shaped, and movable relative to the fixed portion and the movable portion. The second segment is plate-shaped and affixed on the movable portion, wherein a thickness direction of the first segment is different from a thickness direction of the second segment. The third segment is plate-shaped and affixed on the fixed portion, wherein the second segment is movably connected to the third segment through the first segment.
