ACTUATOR FOR MOBILE DEVICE

摘要

PROBLEM TO BE SOLVED: To minimize the occurrence of tilt of a bobbin when an actuator for a mobile device is driven and to enhance a sensitivity characteristics of wires, thereby minimizing power consumption.

SOLUTION: The actuator 100 for mobile device comprises: a holder 110 having a coil 111 wound along inner side surfaces thereof; a driven unit 120 that is inserted into the holder 110 such that four side surfaces of the driven unit are spaced at a predetermined distance from side walls of the holder 110, the driven unit having magnets 123 coupled to the respective side surfaces thereof; a pair of suspension wires 125 that is mounted point-symmetrically with each other on the upper portion of the driven unit such that an arbitrary portion of each suspension wire is bent and directed toward the corner of the driven unit 120; a pair of support plates 126 that is coupled at both lower sides of the driven unit 120 such that elastic forces are generated in opposite directions to each other; and upper; and lower holder covers 113, 114 covering upper and lower parts of the holder 110.
