Abstract
A fixed support for voice coil motor comprises a coil, hollow plate, opening, structural reinforcement beam, and a plurality of pins. The pins extruding from the hollow plate allows the coil to wind around them. The opening, which locates on the center of the hollow plate, distributes stress concentration around the center. The structural reinforcement beam, which extrudes from an edge of the hollow plate, improves stiffness of the fixed support, thereby allowing the hollow plate to be made thinner.
