PURPOSE: A linear vibrator is provided to implement the stability of linear vibration by changing the structure of a coil and magnet generating an electromagnetic force for vibration. CONSTITUTION: A fixing part(110) provides the internal space of a certain size. At least one magnet(122) generates a magnetic force. A vibrator(130) comprises a coil(132) generating an electromagnetic force and a mass(134). A substrate(140) forms a free end by combining with the vibrator. The other end of the substrate forms a fixed end by combining with the fixing part. A joint protrusion(113) is inserted into a joint hole formed in the substrate.
