A vibrator structure is provided to prevent permanent deformation of a vibrating member by protecting the vibrating member from being collided against an inner surface of a fixed member by using plural guide bumps around a ring weight. Corresponding upper and lower cases(110,120) are coupled with each other via a fixed member. An elastic force generator(130) is provided on at least one surface of the upper and lower cases(110,120). A vibrating member is elastically support by an elastic member one end of which is fixed on an inner wall of the fixed member. A vibrator is vibrated by a pulling or repelling force generated between a magnet(140) and the elastic force generator(130). The vibrating member includes an insertion hole for the magnet at the center thereof, a ring weight(151), and a back yoke(153). The ring weight(151) forms plural guide bumps which are extended outside the insertion hole to face the inner wall of the fixed member. The back yoke(153) is coupled with the ring weight(151) and an upper portion of the magnet(140).
