Lens assembly with actuating means and auto-focus controlling apparatus having the same
Abstract:
A lens assembly has a driving actuator which includes a magnet, a yoke and a coil and is formed along a lens barrel that accommodates a lens unit for focusing and an auto-focus controlling apparatus comprises the lens assembly for camera module. The magnet or the coil has an internal diameter smaller than a maximal diameter of the lens barrel. Therefore, it is possible to manufacture much smaller lens assembly according to the present invention compared to the conventional ones and to reduce the possibility of component damages in the lens assembly in operating the camera module.
Abstract(Chinese):

透镜组件具有驱动致动器，其包括磁体，磁轭和线圈，并且沿着容纳用于聚焦的透镜单元的透镜镜筒形成，并且自动对焦控制装置包括用于相机模块的镜头组件。 磁体或线圈的内径小于镜筒的最大直径。 因此，与传统的相比，可以制造出根据本发明的更小的透镜组件，并且降低了在操作相机模块时在透镜组件中的部件损坏的可能性。
