Abstract: A lens driving module for holding and moving a lens is provided, including a lens holder having an accommodating space, a driving coil, a plurality of first magnetic members having a longitudinal structure, a virtual plane, and a plurality of second magnetic members, wherein the lens is disposed in the accommodating space. The lens holder is disposed between the first magnetic members and between the second magnetic members. The driving coil is disposed on the lens holder and surrounds the accommodating space. The virtual plane is perpendicular to a longitudinal axis of the longitudinal structure. The projections of the driving coil and the first magnetic members on the virtual plane along the longitudinal axis of the longitudinal structure overlap each other. When a first current flows through the driving coil, the lens holder moves relative to the first and second magnetic members along a first direction.

Abstract: The present invention provides a VCA-based lens driving device. By way of giving an improved OIS coil structure, a magnetic induction element used to sense movement of magnets atop which maybe cause from a user's hand shaking can be placed as far away from OIS coils as possible. The impact of the magnet field of the OIS coil on the magnetic induction element is thus reduced. In one embodiment, the OIS coil is down-sized to reduce the influence of the OIS coil on the magnetic induction element placed beside it. In another embodiment, the OIS coil has a one-sided indention and the magnetic induction element is placed below/or beside the indention of the OIS coil.
