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.
Abstract translation: 本发明提供了一种基于VCA的透镜驱动装置。 通过提供改进的OIS线圈结构，用于感测可能由用户的手抖动引起的顶部的磁体的移动的磁感应元件可以尽可能远离OIS线圈。 因此，OIS线圈的磁场对磁感应元件的影响减小。 在一个实施例中，OIS线圈尺寸减小以减小OIS线圈对放置在其旁边的磁感应元件的影响。 在另一个实施例中，OIS线圈具有单侧缩进，并且磁感应元件放置在OIS线圈的凹槽之下或旁边。
