| 1. An actuator for a mobile device, comprising:
a holder having a coil wound along inner side surfaces thereof;
a driving unit that is inserted into the holder such that four side surfaces of the driving unit are spaced at a predetermined
distance from side walls of the holder, the driving unit having magnets coupled to the respective side surfaces thereof;
a pair of suspension wires that are mounted symmetrically with each other on an upper portion of the driving unit such that
an arbitrary portion of each suspension wire is bent and directed toward a corner of the driving unit; and
a pair of support plates that are coupled to both lower sides of the driving unit such that elastic forces are generated in
opposite directions to each other.
