A portable telephone includes a telephone body containing telephone circuitry, a rechargeable cell, and a power generation device having a magnet structure, a coil, and a rectifier for generating a direct current (D.C.) voltage to charge the rechargeable cell. The magnet structure may be an armature and the coil may be fixed, or the magnet structure may be a stator and the coil may be movable. The magnet structure may be a multiple pole magnet made up of a plurality of individual pole structures, each pole structure including a pair of magnets joined to each other with facing poles of like polarity. In addition, the coil may include clockwise and counterclockwise windings arranged in a multi-layered stacked arrangement. |
