Abstract:
The present invention relates to a haptic actuator that generates vibration, and more particularly, to a vibration actuator that can reduce falling time of vibration after applied power is blocked while maintaining a vibration force. A haptic actuator of the present invention is an actuator that vibrates using an electromagnetic force generated by a magnet and a coil, and the haptic actuator includes a case that has a space in the inside thereof; a fixing member that is fixed to the case; a vibrating body that vibrates in the right and left directions about the fixing member; an elastic member that is bent several times and elastically supports the vibrating body so that the vibrating body maintains at the initial position; and an insertion member that is inserted into a wrinkle space formed by the bending of the elastic member, and the insertion members act against the elastic force of the elastic member and thus falling time of the vibrating body is decreased, when the vibrating body is vibrated in the right and left directions by the elastic force of the elastic member after the electromagnetic force is removed.
