Camera Module

摘要

The present disclosure relates to a camera module including a fixture; a moving part centrally coupled with a lens and arranged to move relative to the fixture; three or more magnets arranged at a periphery of the moving part; and three or more coils arranged from an inner surface of the fixture to areas opposite to the three or more magnets, where each of the coils independently receives a control signal so that the moving part moves to a height direction and tilted relative to a central axis of the moving part, whereby a lens can be axially moved and tilted at the same time using arrangement of a single set of coils and magnets.
