Abstract

A device for converting into electrical energy the mechanical energy associated with vibrations generated by vibrating means (18) to which the device is connected, comprising at least one ferromagnetic stator (14) with a coaxial winding (15) and a magnetic mass (1 1) mobile in relation to the stator, the magnetic mass and the stator with the relative winding forming a magnetic circuit. The magnetic mass (11) is movable perpendicularly to the axis of the winding (15) in response to vibrations generated by the vibrating means (18), whereby the magnetic circuit has a correspondingly variable gap width. Elastic means (16,17) are provided at the ends of stroke of the mobile magnetic mass, the winding being electrically connected a system (20) for storing the energy produced via a conditioning circuit (19).
