A DC brushless vibration motor is disclosed. It separately applies an inductance coil and a magnetic component with a plurality of common-plane magnetic poles to be the rotator and the stator of the motor. The inductance coil is a single loop winded by a single conductive wire, and the winding region corresponds to the two magnetic poles with the same polarity of the magnetic component. The magnetic component includes a centrifugal groove for deviating the gravity center of the magnetic component away from the axis. When current flows into the inductance coil to form a magnetic field, it is mutually exclusive to the magnetic fields generated by the magnetic component, and results to a rotation. The gravity center of the magnetic component deviating from the axis causes a vibration amount.
