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.
