Abstract

The invention discloses a voice coil motor. The motor comprises a top cover, a shield, a coil, a magnet, springs, a lens mount, a base and a stopper, wherein the coil is noncircular, and has four corners each formed by a quadrant with an arbitrary radius; an even number of snap grooves are arranged on side walls of a lower edge of the shield, and a plurality of projections with oblique angles are arranged on side edges of the base; and a fixed connection structure of the shield and the base is formed by the snap grooves and the projections. The voice coil motor provided by the invention has the advantages of simplicity in design and assembly, and overcomes the defects of large number of components and complex structure of the conventional voice coil motor, achieving excellent performance in quality improvement.

Description

technical field [0001] The invention relates to a voice coil motor. Background technique [0002] The structure of the voice coil motor used in video devices includes three basic elements such as coils, magnets, and springs, and other components that make up the motor will be developed from these three components.
