PURPOSE: A vibrator device for a linear motor is provided to reduce manufacturing cost by improving coupling structure between the frame and permanent magnet, while achieving improved efficiency of the linear motor by reducing air gaps. CONSTITUTION: A vibrator device for a linear motor, comprises a frame(131) which is shaped as a cylinder having an open side and has a permanent magnet mounting portion formed at the outer periphery of the frame; and a plurality of permanent magnets(134) mounted at the permanent magnet mounting portion of the frame, wherein permanent magnets are fixed by a fixing unit formed by extending and bending the side portion of the permanent magnet mounting portion. The fixing unit includes a first flange(136) vertically protruded from an end of the frame so as to support the lower portion of the permanent magnet, and a second flange(137) vertical protruded from the end of the frame so as to support the upper portion of the permanent magnet.
