Abstract
The energy transducer includes an upper part and a lower part. The upper part having a housing, a helix metal spring, a first circular board, a second circular board with a short metal shaft, a ball bearing engaged to the short metal shaft, a third circular board with a groove to receive metal bearing balls, an upper metal shaft welded to the bottom of the third circular board, four arc-shaped springs welded to the bottom of the third circular board, and four sets of wheels rotatably attached to one end of the spring. The lower part includes: a housing, a lower metal shaft, a fourth circular board placed on the upper end of the lower part, bundles of electric wire, pluralities of permanent magnets, and a fifth circular board placed at the lower end of the lower part. As the helix metal spring is compressed by an external force, the bundle of electric wire turns between permanent magnets to produce electricity. Direction of the electricity alternates as the helix metal spring oscillates.
