Abstract: An optical system includes a base, a first lens driving module, and a second lens driving module. The first lens driving module includes a first lens holder, a first magnet, and a first coil. The first lens holder is configured to hold a first optical element. The first coil corresponding to the first magnet is configured to drive the first lens holder to move relative to the base. The second lens driving module includes a second lens holder, a second magnet, and a second coil. The second lens holder is configured to hold a second optical element. The second coil corresponding to the second magnet is configured to drive the second lens holder to move relative to the base. The first magnet is disposed between the first and second lens holders, and no other magnet is disposed between the first and second lens holders except the first magnet.

Abstract: A driving mechanism for moving an optical element is provided, including a housing, a frame, a holder, and a driving assembly. The frame is fixed to the housing and forms a depressed surface adjacent to the housing. Specifically, the depressed surface faces the housing and is not in contact with the housing. The holder is movably disposed in the housing for holding the optical element. The drive assembly is disposed in the housing to drive the holder and the optical element to move relative to the frame.

Abstract: The present invention provides some configurations of flexible connections jointly or integrally formed with a movable part and/or a fixed part of a lens module. The flexible connections may move the movable part along an optical axis direction and/or directions perpendicular to the optical axis. The configuration and material of the flexible connections provide an enhanced strength bearing plastic deformation, and hence increasing the structure strength of the lens module. The formation of the flexible connections with the movable part and/or the fixed part with one mold-injection process can reduce parts of the lens module and simply its manufacturing process.

Abstract: A lens driving device that is based on a Voice Coil Actuator (VCA) structure and provides the auto-focusing and optical image stabilization (OIS) functions. These two functions can be realized by a common magnet scheme, or a separate magnet scheme. Also, the present invention provides an improved structure for the lens driving device to enhance the function of OIS thereof. By arranging a magnetic enhancement device below the OIS coils in the lens driving device, the magnetic driving force of the OIS coils and magnetic induction of the Hall sensors, if present, can be enhanced, and the magnetic sensitivity thereof may be also improved.
