Abstract
An electric energy generator from a vibrational field includes a body of non-ferromagnetic material, at least one pair of permanent magnets pivotally hung from the body in such a way that they are arranged therebetween. The magnets have faces of equal magnetic polarity turned to each other from opposite sides of the body, whereby a repulsive force is established between the magnets tending to keep them spread apart in an equilibrium position. A plurality of electric coils is arranged on the surface of the body so as to intercept the magnetic field generated by the magnets. The body is configured to be connectable to a vibration source, the vibration contrasting the repulsive force and causing an oscillation of the magnets about the equilibrium position, thereby generating a magnetic flux variation and thus an electric power production as an output from the electric coils.
