主权项 1. A linear vibrator comprising: a fixing unit having a magnet in an inner space, the magnet generating magnetic force; a vibration unit including a coil disposed to face the magnet and generating electromagnetic force by interaction with the magnet, and a holder on a lower surface of a mass body in an axial direction; a damper having a ring shape and having an inner circumference which is greater than an outer circumference of the magnet; an elastic member coupled with the holder and the fixing unit and providing elastic force to the vibration unit; and an upper surface of the elastic member in the axial direction is coupled with a lower surface of the holder in the axial direction by welding.
