    Abstract: A driving mechanism for supporting an optical member is provided, including a fixed module, a movable module, a driving module disposed therebetween, and an elastic member. The driving module can drive the movable module to rotate around a first rotation axis relative to the fixed module. The elastic member includes a first connecting portion connected to the movable module, a second connecting portion connected to the fixed module, a first string portion connected to the first connecting portion, and a first buffer portion connected to the first string portion. The first string portion is disposed on the first rotation axis. The longitudinal axis of the first string portion is parallel to the first rotation axis. The first buffer portion has wave-shaped structure.

    Abstract: An optical driving mechanism is provided, configured to force an optical element, including a base, a movable portion, and a driving portion. The movable portion is disposed and connected to the base. The movable portion includes a holder configured to sustain the optical element, a magnetic element, and a fixing member. The magnetic element and the fixing member are affixed to the holder, wherein the fixing member has a permeable material. The driving portion is configured to force the movable portion to move relative to the base, wherein the driving portion includes a piezoelectric element and a support member connecting thereto. The piezoelectric element and the support member are disposed on the base and connected to the movable portion. The fixing member makes contact with the support member via a magnetic attraction force between the magnetic element and the fixing member.

    Abstract: A lens driving module includes a reflecting element, a base, a frame, a holder, an optical lens, a first electromagnetic driving assembly, and a second electromagnetic driving assembly. The frame is connected to the base, and the holder holds the optical lens and movably connects to the base. The reflecting element reflects light from the outside along a light incident direction to an optical lens along a first direction, wherein the light incident direction is substantially perpendicular to the first direction. The first and second electromagnetic driving assemblies are configured to force the holder and the optical lens to move relative to the base, wherein the first and second electromagnetic driving assemblies are situated in different positions in the light incident direction.
