PURPOSE: A linear vibrator is provided to secure miniaturization and slimming by changing the shape of a bracket and a mass substance, thereby preventing the deterioration of a vibrating element. CONSTITUTION: A fixing unit includes a case(112) for an internal space; and a bracket(114) for connecting the case. A magnet(122) is arranged in the case to generate magnetic force. A vibration part(130) comprises a coil(132) for generating electromagnetic force by using the magnet; and a mass substance(134). An elastic member(138) is fixed to the fixing unit and supports the vibration of the vibrator. A protrusion(134a) is formed in the bottom surface of the mass substance to absorb the impact due to the contact between the bracket and the mass substance. |
