Abstract

A self-rechargeable telephone having includes a power generation device capable of converting mechanical energy into electric energy and storing the electric energy in a battery cell. The direct-current voltage generated by the power generation device is obtained by reciprocally moving the magnetic body inside the coil winding to induce electric energy in the coil, and by then rectifying the electric energy.

Claims

1. A self-rechargeable portable telephone, comprising:

a portable telephone body, including circuitry for receiving and transmitting data signals;

a power generation device, having a magnetic body and a coil winding, for generating direct-current (D.C.) voltage upon movement of the telephone;

a rechargeable cell, capable of recharge by using said direct-current (D.C.) voltage; and

at least one overload protection control/rectifier device, for protection of the portable telephone body and the rechargeable cell,

wherein said D.C. voltage generated by the power generation device is obtained by causing reciprocal movement of the magnetic body inside the coil winding upon movement of the telephone to induce electric current in the coil winding and rectifying of the electric current.

2. The self-rechargeable portable telephone according to claim 1, wherein said magnetic body includes a permanent magnetic material.

3. The self-rechargeable portable telephone according to claim 1, wherein said generator includes a coil, and said coil contains a permeable material or air core.

4. The self-rechargeable portable telephone according to claim 1, wherein said rechargeable cell is a secondary cell.
