PURPOSE: A linear vibrator is provided to prevent collision between a moving unit and a component by vibrating the moving unit along a support shaft. CONSTITUTION: A linear vibrator comprises a stator(60), a support shaft(61) and a moving unit(62) A stator includes a case(80), a circuit board(81), and a coil(82). The case has a preset space. The circuit board is arranged inside the case. The coil is connected to the circuit board. The support shaft is inserted into the case. The moving unit is comprised of a bearing(84), a mass unit(85), and a magnet(86). The bearing is movable contacted with the outer circumference of the support shaft. The mass unit surrounds a part of the bearing. The magnet is supported on one side of the mass unit.
