Summary: | A device for charging a battery of a mobile phone is provide to drive a small-sized generator by using a movement power of a pendulum generated while walking, and to charge the battery by using an electric current generated from the small-sized generator, thereby maximally extending a battery using time. A battery(10) is connected to the backside of a mobile phone to supply a power, and comprises as follows. A pendulum(10) is built in a case(1a) of the battery(10), and rotated around an axis(11a) of a drive gear(11). A following gear(13) is meshed with an idle gear(12) for accelerating meshed with the driver gear(11), and receives a power of the pendulum(10). A generator(14) generates an induced current between a rotator rotated by a movement power of the following gear(13) and a stator. An amplifier amplifies the induced current generated from the generator(14). A transformer(30) converts the amplified current into a voltage proper to be charged. A microphone(40) collects a sound. An oscillator voice/current converter(41) converts the collected sound into a current energy. A vibration sensor(50) collects a vibration. A piezoelectric element vibration/current converter(51) converts the collected vibration into a current energy. |
