1. An optical element driving mechanism, comprising:
a movable part, connected to an optical element;
a fixed part, wherein the movable part is movable relative to the fixed part; and
a driving assembly, driving the movable part to move relative to the fixed part,
wherein the movable part is settled on the fixed part via a frictional force,
wherein the driving assembly comprises:
an electromechanical converting element;
a transmission element;
a weight element; and
a first connecting element to a fourth connecting element,
wherein the transmission element is disposed on the fixed part or the movable part via the third connecting element,
wherein the weight element is disposed on the fixed part or the movable part via the fourth connecting element, and
wherein the fourth connecting element is not in direct contact with the electromechanical converting element.
