PURPOSE: A portable electric energy generating apparatus is provided to obtain a simple structure for the portable electric energy generator, reduce manufacture cost, and convert vibration energy to electric energy. CONSTITUTION: A portable electric energy generating apparatus comprises an outer case, a cover, four fixed element, four movable element(30), upper and lower tension springs, upper and lower spring sheets, a rectifier, a battery and a static voltage regulator. The movable elements(30) vertically move within through-holes of the fixed elements inside the outer case for generating electricity induced by magnetic force from magnets of the fixed elements. The upper and the lower tension springs support the movable elements(30). The upper and the lower spring sheets are made of rubber for suppressing horizontal movement of the upper and the lower tension springs. Each of the movable elements(30) includes an upper and a lower insulating elements(31a,31b), many insulating plates(32) between the insulating elements(31a,31b), many magnetic rods(33) arranged between the magnet plates(32) and insulated by insulating coverings, and many coils(34) wound around the magnetic rods(33). |
