PURPOSE: A linear vibrating motor is provided to secure concentricity by accurately positioning an electromagnetic force part at the inner center of the linear vibrating motor through providing a casing which is accommodating the electromagnetic force part which is composed of multiple magnets. CONSTITUTION: A stator part(100) comprises a magnetic force part(110) and a casing(120). The casing accommodates the magnetic force part. A vibrator part(200) comprises a coil(210) and a printed circuit board(220). The coil generates electromagnetic force. One end of a printed circuit board is combined with the stator part. The other end of the printed circuit board is combined with the coil. The vibrator part linearly moves along the outer peripheral surface of the longitudinal direction of the casing.
