CAMERA MODULE ACTUATOR

The invention provides a camera module actuator. An actuator includes a magnet, a driving coil facing the magnet, a driver, and a position calculation processor. The driver is configured to move the magnet in at least one of an optical axis direction and a direction perpendicular to the optical axis by applying a driving signal to the driving coil. The position calculation processor includes sensing coils, and is configured to calculate a position of the magnet according to inductance levels of an inductor of the sensing coils. The inductance levels vary according to movements of the magnet. 本发明提供种相机模块的致动器。所述致动器包括磁体、面对所述磁体的驱动线圈、驱动器和位置计算处理器。所述驱动器被配置为通过向所述驱动线圈施加驱动信号来使所述磁体在光轴方向和与所述光轴垂直的方向中的至少个方向上运动。所述位置计算处理器包括感测线圈，并被配置为根据所述感测线圈的电感器的电感水平来计算所述磁体的位置。所述电感水平根据所述磁体的运动而变化。
