1. A driving mechanism for moving a flat optical element, comprising:
a fixed part;
a movable member, movably disposed on the fixed part and connected to the optical element;
a slider, having a hinge pivotally connected to the movable member;
a driving assembly, configured to impel the movable member and the optical element to move relative to the fixed part, wherein the driving assembly has a coil disposed on the fixed part and a magnetic element disposed on the slider; and
a yoke, extending through the coil;
wherein the hinge and the magnetic element are located on opposite sides of the slider, and the polar direction of the magnetic element is perpendicular to a central axis of the coil;
wherein when a current signal is applied to the coil, the coil and the magnetic element generate an electromagnetic force to impel the slider and the magnetic element in a linear direction relative to the coil, and the movable member is forced to rotate relative to the fixed part along a curved path, wherein the linear direction is parallel to the central axis.
