Lens driving mechanism and method for controlling the same

A driving mechanism, configured to drive an optical element, comprising:

• a holder, configured to sustain the optical element having an optical axis,
• a base, having a polygonal structure with a first side and a first corner, the first side extends along a direction that is perpendicular to the optical axis;
• a first driving assembly, disposed on the first side to drive the holder to move relative to the base;
• and
• a circuit assembly, disposed on the first side, comprising a first circuit, a second circuit and a third circuit, wherein the first circuit and the second circuit extend along a direction that is not perpendicular to the optical axis, and the third circuit is connected to an external circuit,
• wherein the circuit assembly further comprises a first circuit contact and a second circuit contact, the first circuit is electrically connected to the first driving assembly via the first circuit contact, and the second circuit is connected to the first driving assembly via a second circuit contact
• wherein the base comprises a first protruding structure and a second protruding structure, and the first protruding structure and the second protruding structure are parallel to each other, the first protruding structure is disposed on the first corner, wherein the first circuit contact and the second circuit contact are disposed on the first protruding structure,
• wherein a part of the third circuit is disposed on the second protruding structure.
