LENS ACTUATOR CAPABLE OF MANUFACTURING WITH LOW COST AND MINIATURIZING BY ADOPTING A VOICE-COIL MOTOR(VCM) ATTACHABLE TO MOBILE EQUIPMENT

摘要

PURPOSE: A lens actuator capable of manufacturing with low cost and miniaturizing is provided to exclude the influence of an electromagnetic wave occurring from a separate external electronic component mounted to the outside of a camera module, to assemble easily and to make miniaturization possible. ;CONSTITUTION: A lens actuator capable of manufacturing with low cost and miniaturizing comprises: a lens module(200) including a carrier(220) housing a lens unit to photograph a subject; a driving unit(300) moving the lens module in the optical axis direction by the reciprocal action between a magnet(310) and a driving coil(320) which are arranged along the outer circumference of the carrier; a shield case(600) forming a shield unit covering the top of the magnet and extended in the optical axis direction along the outer circumference of the magnet and the driving coil as polyhedral shape provided with a hollow; and a base(700) supporting the bottom of the carrier and the driving unit.;COPYRIGHT KIPO 2011
