The present invention relates to a vibration actuator comprising: a power supply part to supply AC power; a solenoid to generate magnetic reaction by generating a magnetic field using the AC power supplied from the power supply part; left and right elastic members having permanent magnets on both sides of the solenoid to face each other, wherein the left and right elastic members move back and forth in a horizontal direction in accordance with the changes in the magnetic field induced by the AC power supplied to the solenoid; and a fixture placed below the solenoid, wherein a lower tip of the left and right elastic members is fixated. According to the present invention, the vibration actuator vibrates using the solenoid mounted on a center and left and right elastic members having permanent magnets mounted on both sides of the solenoid; and reduces power loss caused by refraction by eliminating a frictional area, preventing wear and refraction of power from the frictional area.
