    Abstract: A lens driving mechanism is provided. The lens driving mechanism is configured to drive an optical lens, including a holder, a base, a first elastic element, and a first biasing element. The optical lens is disposed in a receiving space of the holder. The base has a central axis, and the holder is movable relative to the base. The first elastic element is connected to the holder and the base. The first biasing element exerts a force on the holder so that an optical axis of the optical lens has an angular displacement relative to the central axis.

    Abstract: The present disclosure provides a vibration device, including a stator, an eccentric wheel and an electromagnetic driving assembly. The eccentric wheel rotates around a rotating shaft relative to the stator. The electromagnetic driving assembly includes at least one magnetic element and an induction coil. The at least one magnetic element is disposed on the eccentric wheel. The induction coil corresponds to the magnetic element, and the induction coil is disposed on the stator. When a current is applied to the induction coil, the induction coil acts with the magnetic element to generate an electromagnetic force to drive the eccentric wheel to rotate around the rotating shaft, so that the vibration device generates a vibration. The rotating shaft is disposed on the stator.

    Abstract: An optical element driving mechanism is provided, including an immovable part, a movable part, a driving assembly, and an elastic assembly. The movable part is movable relative to the immovable part. The movable part accommodates an optical element. The driving assembly drives the movable part to move relative to the immovable part. The elastic assembly is elastically connected to the immovable part and the movable part. The elastic assembly includes a base and a plurality of wires. The base includes a first portion extending along a first direction. Each of the wires includes a second portion extending along the first direction. The second portions are at least partially disposed on the first portion. The second portions at least partially overlap with each other as observed from a second direction that is not parallel with the first direction. The second portions are arranged along the second direction.
