Abstract

A camera module is provided, comprising: a mover mounted with a lens; a stator supporting the mover to an optical direction of the lens; a side actuator mounted with a coil and a magnet moving the mover to the optical direction relative to the stator; a ball interposed between the mover and the stator; and coils, each coil provided at the mover and the stator to guide a linear travel of the ball, wherein the side actuator is lopsidedly arranged at each one side of the stator and the mover.

Description

technical field [0001] The present invention relates to a camera module (CAMERA MODULE) equipped with a coil for providing a driving force required for relative movement of a moving part and a fixed part. Background technique [0002] With the continuous improvement of mobile phone pixels, the focus of competition in the mobile phone industry market has gradually evolved into camera control technology that can achieve high-definition image quality. A compact digital camera module with high-resolution features needs to be equipped with an auto-focusing function in order to achieve high-definition image quality despite its small size. [0003] At present, the autofocus function is generally applicable to traditional digital cameras, but there are still many difficulties in realizing the compact digital camera modules whose length and width are reduced to within tens of mm. [0004] In order to realize the autofocus function in a compact camera module, an innovative modificati...
