A VCM (voice coil motor) is disclosed, the VCM including: a rotor including a lens-accommodating, both ends opened cylindrical bobbin and a coil block including a coil wound on a periphery of the bobbin; a stator including a cylindrical yoke formed with a lens-exposing opening, a plurality of magnets disposed inside the yoke and opposite to the coil block, and a housing disposed inside the yoke to fix the plurality of magnets; and an elastic member elastically supporting the bobbin.

Voice coil motor

A motor for driving a lens is disclosed, wherein a yoke comprises a rotation prevention unit configured to prevent the bobbin from rotating.

Motor for driving lens

A VCM (voice coil motor) is disclosed, the VCM comprising: a bobbin formed with a support unit protruded from a periphery of a body at a bottom portion of the body, and a recess unit partially removed at the support unit; and a coil block supported by the support unit and including a plurality of coil layers wound at a periphery of the bobbin, wherein first and second distal ends of the coil block pass through the recess unit.

Voice coil motor, coil block for voice coil motor, method of manufacturing the coil block, and voice coil motor having the coil block

An exemplary embodiment of the present disclosure includes a first PCB Printed Circuit Board mounted with an image sensor, a housing unit arranged on an upper portion of the first PCB, a holder module spaced apart from an inner bottom surface of the housing unit at a predetermined distance, wound on a periphery with a first coil and having at least one lens thereinside, a second PCB mounted on an upper portion of the holder module, a plate member coupled to a bottom surface of the holder module, a plurality of wire springs connected at one end to the second PCB and connected at the other end to the plate member, and a coil fixing unit configured to fixedly position the first coil to a periphery of the holder module.

Camera module

A VCM is disclosed, the VCM including a base formed with an opening; a bobbin arranged on an upper surface of the base and mounted with a lens therein; a plurality of magnets secured on the base to face a periphery of the bobbin; a coil block encompassing each magnet and the bobbin, and secured to a part of the bobbin exposed between the magnets; and a cover can encompassing the magnets and the coil block.

A VCM (voice coil motor) is disclosed, the VCM including: a rotor including a lens-accommodating, both ends opened cylindrical bobbin and a coil block including a coil wound on a periphery of the bobbin; a stator including a cylindrical yoke formed with a lens-exposing opening, a plurality of magnets disposed inside the yoke and opposite to the coil block, and a magnet fixing member disposed inside the yoke to fix the plurality of magnets; and an elastic member elastically supporting the bobbin.

A VCM (voice coil motor) is disclosed, the VCM including: a rotor including a lens-fixing hollow holed bobbin including a coil discharge unit formed from a peripheral upper end to a peripheral bottom end facing the peripheral upper end, and a coil block arranged at a periphery of the bobbin and including a cylindrically wound coil; a stator including a magnet facing the coil block and a yoke fixing the magnet; a case including a bottom case arrange with the bobbin and an upper case coupled to the bottom case and having an opening at a portion corresponding the bobbin; and an elastic member elastically supporting an upper end of the bobbin and a bottom end facing the upper end of the bobbin, wherein a distal end of the coil arranged at an upper end of the coil block employs the coil discharge unit to be discharged to a bottom end of the bobbin.
