Abstract: An electromagnetic driving device is provided, which includes a stationary portion, a movable portion adapted to support an element, a number of rolling balls, a driving magnet, a driving coil, and a magnetic attraction element. The stationary portion and the movable portion are arranged along a main axis. The rolling balls and the driving magnet are positioned between the stationary portion and the movable portion. The driving coil is arranged to correspond to the driving magnet and configured to enable the movement of the movable portion along a direction perpendicular to the main axis. The magnetic attraction element is arranged to correspond to the driving magnet. The magnetic force between the magnetic attraction element and the driving magnet is greater than the sum of the weight of the movable portion, the element, and the magnetic member.

Abstract: The tri-axis close-loop feedback controlling module for electromagnetic lens driving device includes a 6-pin Hall element. Two pins of the Hall element are coupled to an auto-focus module for providing a current to drive the auto-focus module to conduct auto-focusing operations along the Z-axis; while other four pins of the Hall element are coupled to a control unit. The control unit detects the X-Y axial positions of the auto-focus module relative to an OIS module and generates a control signal which is then sent to the Hall element. Therefore, the Hall element not only can provide its own feedback controlling function according to the Z-axial position of lens, but also can drive the auto-focus module based on the control signal corresponding to the X-Y axial positions of the auto-focus module, so as to achieve the goal of tri-axis close-loop feedback controlling for the electromagnetic lens driving device.

Abstract translation: 用于电磁透镜驱动装置的三轴闭环反馈控制模块包括一个6针霍尔元件。 霍尔元件的两个引脚耦合到自动对焦模块，用于提供电流以驱动自动对焦模块沿着Z轴进行自动聚焦操作; 而霍尔元件的其他四个引脚耦合到控制单元。 控制单元检测自动对焦模块相对于OIS模块的X-Y轴向位置，并产生一个控制信号，然后发送到霍尔元件。 因此，霍尔元件不仅可以根据透镜的Z轴位置提供自己的反馈控制功能，还可以根据与自动对焦模块的XY轴位置对应的控制信号来驱动自动对焦模块 ，以实现电磁透镜驱动装置的三轴闭环反馈控制的目的。
