Abstract: Provided is an actuator for a mobile device including 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 the 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.

Abstract: An actuator includes a focusing-substrate having a focusing coil pattern for generating focusing driving force, the focusing-substrate being provided with a land part and a hole through which laser beams pass, tracking coils for generating tracking driving force, the tracking coils being wound around opposite sides of the focusing substrate in parallel with the a wire direction, magnets for providing magnetic force to the focusing coil pattern and the tracking coils, and a yoke plate provided with a pair of first yokes for fixing the magnets.

Abstract: An actuator for a mobile terminal using suspension wires is disclosed. By using an actuator for a mobile terminal comprising a holder, magnets mounted inside the holder, a coil mounted inside the holder and positioned on the inside of the magnets, a bobbin joined with the coil and having a lens in its center, and suspension wires, the ends of which are joined to the holder, bent at a particular angle to elastically press the bobbin, the manufacturing process may be simplified and the manufacturing cost may be reduced.

Abstract: Disclosed herein are a yoke plate for optical pick-up actuators, a combination structure of a suspension PCB and a yoke plate, and an optical pick-up actuator comprising the structure. The yoke plate comprises a rear yoke at the distal end of one side of the yoke plate, and the rear yoke has damping-gel fillers for attenuating a partial resonance of the suspension wires. The yoke plate is simplified in construction by supporting the suspension PCB using the rear yoke instead of a conventional wire holder, so that assembly process can be simplified and the manufacturing costs can be reduced. The suspension PCB is combined with the yoke plate by bonding or soldering instead of screw fastening, so that the suspension PCB can be combined with the yoke plate without displacement or distortion. The optical pick-up actuator with the combination structure can be provided by a simplified assembly process and reduced manufacturing costs.
