    Abstract: An optical member driving mechanism for driving an optical member having an optical axis is provided, including a fixed portion, a movable portion, a first elastic member, and a driving assembly. The movable portion is configured to hold the optical member, and is movably connected the fixed portion via the first elastic member. The driving assembly drives the movable portion to move along the optical axis within a range of motion. The range of motion includes a first limit moving range and a second limit moving range. The first limit moving range is the maximum distance that the movable portion can move toward the light-entering side, and the second limit moving range is the maximum distance that the movable portion can move toward the light-emitting side. When the movable portion is in a predetermined position, the first limit moving range is greater than the second limit moving range.

    Abstract: An electromagnetic driving assembly is provided, including a movable member, a fixed member, a plurality of suspension wires, an electromagnetic component, a conductive layer, and a terminal. The fixed member is spaced apart from the movable member, wherein the movable member and the fixed member are arranged along the main axis. The plurality of suspension wires are elastically connecting the movable member and the fixed member. The electromagnetic component is for driving the movable member to move relative to the fixed member. The conductive layer is formed in the fixed member and electrically connected to the electromagnetic component through the suspension wires. The terminal is exposed by and partially embedded in the fixed member, and electrically connected to the conductive layer, wherein one end of each of the suspension wires is positioned in a recess of the fixed member.

    Abstract: An optical member driving mechanism is provided, including a movable module, a first driving module, and a position detecting module. The movable module includes an optical member holder and a housing. The first driving module includes a first electromagnetic driving assembly disposed on the optical member holder and a second electromagnetic driving assembly disposed on the housing. The first driving module can drive the optical member holder to move relative to the housing. The position detecting module includes a magnetic member and a position detector. The magnetic member is disposed on the optical member holder. The position detector can detect the position of the optical member holder relative to the housing according to a variation in magnetic field direction.
