Self-rechargeable portable telephone
First Claim
1. A portable telephone, comprising:
- a portable telephone body including telephone circuitry;
a power generation device including a magnet structure, coil winding, and rectifier for generating direct current voltage upon movement of the telephone;
a rechargeable cell, capable of recharge by using said direct current voltage; and
at least one overload protection control device for protection of the telephone circuitry and rechargeable cell,wherein said D.C. voltage generated by the power generation device is obtained by causing reciprocal movement of the telephone to induce electric current in the coil winding, and by rectifying the electric current, andwherein said magnetic pole structures each comprises a pair of parallelepiped shaped dipole magnets having two ends and lateral faces, said dipole magnets in said pairs being joined together at said lateral faces such that like poles face each other, and said pairs being joined together at said ends of said individual dipole magnets to form said magnetic pole structures.

Abstract
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.
