Abstract: An optical element driving mechanism includes an optical element, a fixed assembly, a movable assembly, and a driving assembly. The optical element has an optical axis. The movable assembly is movably with respect to the fixed assembly and configured to hold the optical element. The driving assembly is configured to drive the movable assembly to move relative to the fixed assembly. When viewed along the optical axis, the optical element driving mechanism with a rectangular structure has a long side and a short side, and a length of the long side is not equal to a length of the short side.

Abstract: An optical driving mechanism is provided, for driving an optical element, including: a fixed portion, a movable portion, a driving assembly and a position sensing assembly. The movable portion is movably connected to the fixed portion and includes a holder for sustaining the optical element. The driving assembly is configured to drive the movable portion to move relative to the fixed portion. The position sensing assembly is configured to sense a distance of the movable portion relative to the fixed portion, the position sensing assembly includes a sensing magnetic element and a sensor, wherein the sensing magnetic element is disposed on the movable portion and has a rectangular structure. A direction of a long axis of the rectangular structure extends in a direction that is perpendicular to the optical axis of the optical element, and the direction of the long axis is different from the optical axis direction.
