  • VOICE COIL MOTOR AND AUTOFOCUS MODULE HAVING THE SAME
    Publication number: 20160080621
    Abstract: A voice coil motor includes a casing with a receiving space, a plurality of magnetic elements disposed in the receiving space, a carrier movably disposed in the receiving space for carrying a lens unit, a coil wrapped around the carrier, and a resilient member interconnecting the casing and the carrier to seal a gap between the casing and the carrier. The coil interacts with a magnetic field of the magnetic elements when energized for generating a driving force to displace the carrier. The resilient member is movable along with the carrier and is deformed to generate a restoring force that is opposite to the driving force.
