Abstract: A lens driving device includes a base and a frame movably connected to the base. A holder carries a lens and is movably disposed in the frame. A focus driving unit includes at least one first coil disposed on the holder and at least one first magnetic element disposed on the frame and corresponding to the first coil. Electromagnetic induction occurs between the first coil and the first magnetic element, so that the holder is moved along an optical axis of the lens with respect to the base. A tilt driving unit includes several first electromagnetic driving parts disposed on opposite sides of the holder and several second electromagnetic driving parts disposed on the frame and corresponding to the first electromagnetic driving parts. Electromagnetic induction occurs between the first and second electromagnetic driving parts, so that the holder is tilted with respect to the base.

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.
