Abstract

A linear actuator having an elastic injection-molded frame includes a yoke, a permanent magnet attached to a bottom surface of the yoke at a distance from a side surface of the yoke, a top plate attached to a top surface of the permanent magnet, a frame coupled to an outer periphery of the yoke and injection-molded with an elastic material, a protector disposed on the frame, and a coil secured to the protector, with a lower end positioned between the permanent magnet and the side surface of the yoke. The frame includes a yoke coupling portion coupled to the yoke, a fixing portion spaced apart from the yoke coupling portion and coupled to the protector, and two or more bridges for elastically connecting the yoke coupling portion and the fixing portion.
