    摘要： An optical element driving mechanism includes a first movable part, a fixed assembly and a first driving assembly. The first movable part includes an optical element, and the first movable part is movable relative to the fixed assembly. The first driving assembly is configured to drive the first movable part to move relative to the fixed assembly. The optical element driving mechanism further includes a strengthening assembly configured to strengthen the fixed assembly to bear a force along a first axis.

    摘要： An optical element driving mechanism is provided. The optical element driving mechanism includes a first holder, a second holder, a plate, a biasing assembly, and an electromagnetic driving assembly. The first holder holds a first optical element with a first optical axis. The second holder holds a second optical element with a second optical axis. The plate is disposed below the first holder and the second holder. The biasing assembly forces the first holder to move relative to the plate on a plane substantially perpendicular to the first optical axis, and includes a biasing element, wherein when a driving signal is applied to the biasing element, a length of the biasing element is changed. The electromagnetic driving assembly forces the second holder to move relative to the plate and comprising a first magnetic element and a coil.

    摘要： An optical element driving mechanism is provided. The optical element driving mechanism includes a fixed part, a movable part, a driving assembly, and a sensing assembly. The fixed part has a main axis. The fixed part includes a case and a bottom. The case and the bottom are arranged along the main axis. The movable part moves relative to the fixed part. The movable part may hold an optical element with an optical axis. The driving assembly drives the movable part to move relative to the fixed part. The sensing assembly senses a movement condition of the movable part relative to the fixed part. The sensing assembly includes a sensor. The sensor is disposed on the bottom.

    摘要： An optical member driving module is provided, including a moving mechanism, a base, a suspension wire, and an electromagnetic driving mechanism for driving the moving mechanism to move relative to the base. The moving mechanism includes an optical member holder, and the base has a first surface, a second surface, and an opening. The second surface faces the optical member holder and is opposite to the first surface. The opening extends from the first surface to the second surface. The suspension wire extends through the opening, and the opposite ends of the suspension wire are respectively affixed to the first surface and the moving mechanism.

    摘要： A photosensitive element driving mechanism includes a fixed assembly, a first movable assembly, a photosensitive element and a first driving assembly. The first movable assembly includes a circuit member, and the circuit member includes a circuit member body and a movable cantilever. The photosensitive element is configured to receive light along an optical axis. The photosensitive element is disposed on and is electrically connected to the circuit member. The first driving assembly is configured to drive the first movable assembly to move relative to the fixed assembly. The movable cantilever has a first segment extending in a direction different from the optical axis, the first segment is electrically connected to the photosensitive element and the fixed assembly, and the first movable assembly moves relative to the fixed assembly through the movable cantilever. There is a gap between the first movable assembly and the fixed assembly.
