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: A camera system including a telephoto lens module is provided. The telephoto lens module includes a first image sensor, a first assembly, and a second assembly. The first assembly includes a first driving mechanism and a reflecting member connected to the first driving mechanism. The first driving mechanism is configured to drive the reflecting member to rotate around a first axis and a second axis. The second assembly is disposed between the first assembly and the first image sensor, including a second driving mechanism and a first lens. The second driving mechanism is configured to drive the first lens to move along a third axis. The first, second, and third axes are not parallel to each other. When light enters the telephoto lens along the first axis, light is reflected by the reflecting member and through the first lens along the third axis to the first image sensor.

Abstract: The present disclosure relates to an aperture unit having an optical axis. The aperture unit includes a fixed portion, a movable portion, a first blade and a driving component. The movable portion is movably connected to the fixed portion, the first blade movably connects to the movable portion and the fixed portion, and the driving component connects to the movable portion to move the movable portion relative to the fixed portion in a first moving dimension. When the movable portion is moved relative to the fixed portion in the first moving dimension, the first blade is driven by the movable portion to move relative to the fixed portion in a second moving dimension, and the first moving dimension and the second moving dimension are different.

Abstract: A button mechanism is provided, including a housing, a fixing member fixed on the housing, a moving member movably disposed in the fixing member, a pressing member disposed on the moving member, and a driving module for moving the moving member relative to the fixing member. When the pressing member pushes the moving member to move from an initial position along a first direction to a first position, the driving member moves the moving member from the first position along the first direction to a second position. When the moving member is in the second position, the driving member moves the moving member along a second direction to impact the pressing member, wherein the first direction is opposite to the second direction.
