摘要： 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.

摘要： A vibrator equipped with a piezoelectric element comprises: a case of which an upper or lower surface is coupled to an object to be vibrated; a vibrating part which is disposed in the case; a piezoelectric element which is coupled to the vibrating part so as to be deformed, thereby vibrating the vibrating part up and down; and a power supply part which supplies power to the piezoelectric element. The vibrating part is formed with a hooking protrusion which is protruded laterally, and the case is formed with a hooking groove which restricts an up/down and lateral moving distance of the hooking protrusion.

摘要： A camera actuator having autofocusing and image stabilization functions includes a fixing part mounted on a portable terminal; a first coil mounted on the fixed part; a first carrier installed to be movable in the direction parallel with the lens within the fixing part; a magnet mounted on the first carrier in such a manner that the outside surface of the magnet faces the first coil; a second carrier installed to be movable in the direction of an optical axis of the lens within the first carrier and moving along with the first carrier; a second coil mounted on the second carrier, disposed within the magnet and generating a second driving force to the second carrier; a lens part including at least one lens, mounted on the second carrier, and moving along with the second carrier; and a hall sensor sensing the position of the first carrier.
