    • Disclosed is an improved coin-type vibration motor, which has a larger vibration force and is not easily broken even by a strong impact. A permanent magnet in which an N-pole and an S-pole are alternately arranged is disposed centering around a rotation shaft fitted in a center of an inside of the case, and a brush having an upwardly and slantingly extending shape is connected with a flexible printed circuit disposed between the permanent magnet and a bottom surface of the case. A rotor spaced apart from an upper part of the permanent magnet and rotatably supported by the rotation shaft according to that a rotation center is fitted in the rotation shaft. A wiring board including a commutator is assembled with a lower part of a bearing, and plural coils symmetrically spaced apart from each other centering around the rotation shaft and a vibrator of high specific gravity are sequentially layered on the wiring board. The wiring board, the plural coils, and the vibrator are integrally assembled by a resin injection molding body, to form the rotor. The vibrator has a shape of a flat plate shaped like an arc or a fan extending from a circumference of the bearing to a circumference of the rotor. Having a shape eccentric from the rotation shaft due to its arc or a fan shaped coin type, the rotor eccentrically rotates to generate the increased vibration force by the eccentricity.
