Abstract
Some embodiments relate to an energy conversion device, comprising: a casing; an electromagnetic (EM) transducer disposed at one side of the casing; a round magnet disposed in the casing and free to move relative to the casing and the EM transducer in at least two degrees of freedom; and a ferromagnetic object fixed relative to the casing at an opposite side of the casing to the EM transducer and arranged to attract the magnet toward a rest position within the casing. The EM transducer is positioned so that movement of the magnet relative to the EM transducer varies the magnetic field through the EM transducer, thereby generating electrical potential across at least a part of the EM transducer.
