CAMERA MODULE AUTO FOCUS DRIVE UNIT

摘要

An apparatus for driving auto-focusing of a camera module is provided to obtain control linearity of an overall system and reduce power consumption by increasing driving sensitivity. A coil(100) is configured in a winding manner. A magnet(200) generates magnetic flux with respect to the coil(100). A yoke(300) is attached on an inner surface of the magnet(200). The coil(100) is irregularly plated on a PCB(Printed Circuit Board). The yoke(300) includes an outer yoke(304) and an inner yoke(302).
