PURPOSE: A vibration generating module, an actuator thereof and portable device thereof are provided to use a solenoid generating an electromagnetic force which is alternated with a permanent magnet and an unstable structure to significantly increase the speed of response and reaction. CONSTITUTION: Multiple electromagnetic force generation devices generate an electromagnetic force alternating corresponding to a stimulus-conversion signal. A magnetic force generation unit(120) is positioned between multiple electromagnetic force generation units. The magnetic force generation unit generates a magnetic force. A magnetic material provides the magnetic path of the magnetic field. The multiple electromagnetic force generation units respectively comprise an iron core(111) and a solenoid coil(113). |
