Abstract

A spring activated energy transducer is provided. The energy transducer of the current invention generates alternating current (A/C) electricity from abundant external natural forces. The energy transducer is comprised of an upper part and a lower part. The upper part is comprised of a housing, a helix metal spring, a first circular board, a second circular board, pluralities of permanent magnets embedded to the second circular board, a third circular board with pluralities of permanent magnets facing the permanent magnets embedded in the second circular board with same magnetic pole, an upper metal shaft welded to the third circular board, four arc-shaped springs welded to the third circular board, and four wheel sets rotatably attached to one end of the spring. The lower part is comprised of 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.
