PURPOSE: A power connection device of a linear vibrator is provided to supply power to a final coil by electrically connecting each component through welding or heat-fusion. CONSTITUTION: A power connection device of a linear vibrator comprises a case(120), permanent magnets(150), a coil(140), a moving unit(130), a circuit board(180), and one or more springs(132). The case has an inner space. The permanent magnets are arranged in a part of the case. The coil faces the permanent magnets to use electromagnetic force. The mass body(131) of the moving unit is moved by the electromagnetic force of the permanent magnets and the coil. The circuit board supplies power to the case. The springs are arranged between the moving unit and the case. One or more protrusions are formed in parts of the springs. The springs are electrically or mechanically connected to the mass body or the circuit board.
