Abstract: PURPOSE: A vibration generating module using an unstable structure, an actuator, a portable device, or a vibration generating method using the same, and a recording medium thereof are provided to increase response speed by using a partial magnetic path formed by a solenoid. CONSTITUTION: A vibration generating module using an unstable structure comprises multiple magnetic force generating units(110) and an electromagnetic force generating unit(120). The multiple magnetic force generating units generate magnetic force. The electromagnetic force generating unit generates electromagnetic force alternating according to a magnetic pole conversion signal. A partial magnetic path is formed according to lines of magnetic force of the magnetic force generating units and the electromagnetic force generating unit. The electromagnetic force generating unit or the magnetic force generating units move to one side according to the magnetic pole conversion signal to generate vibration.
