1. An apparatus for converting vibration energy into electric power which electrically converts vibration energy produced when a power system is working, comprising:

  • at least one bar magnet unit to which the vibration produced when the power system is working is transmitted;

    a coil unit helically wound around the magnet unit;

    a damping unit positioned between the magnet unit and the coil unit for holding the magnet unit at the helically neutral position of the coil unit during non-vibration and for attenuating the transmission of vibration to the coil unit during vibration; and

    an electrical wire unit for picking up a current flowing to the winding of the coil unit by a change in the magnetic field generated when the vibration produced in the power system causes the magnet unit to move reciprocately along the helical axis of the coil unit.
