Camera module

摘要

Disclosed herein is a camera module in which a movement of a magnet is controlled by only magnetic force between the magnet and a yoke without a spring for controlling the movement of the magnet which operates up and down. The camera module includes: a lens module; and a main frame supporting the lens module and allowing the lens module to be driven in an optical axis direction, wherein the lens module includes: a lens assembly including a plurality of lenses; and a magnet fixed to one side of the lens module, and the main frame includes: a coil facing the magnet, fixed to one side within the main frame, and generating an electric field as power is applied thereto; and a yoke disposed to face the magnet with the main frame and the coil interposed therebetween and controlling driving of the lens module by attraction with the magnet.
