Self power generation device and portable electronic device applying this device

Abstract

This invention relates to a self-generating device and a portable electronic device using it, in which, the self-generating device generates electric energy when the portable electronic device vibrakes and the energy is stored via a circuit and provided to the internal circuit of the electronic device. Said self-generating device includes a support ring with an eccentical ring set in its channel, which is fixed with one or many magnetic balls, said channel is surrounded by one or multiple coils, each of which includes two nodes and is connected to an electric energy collecting circuit by the nodes, and vibration of said portable electronic device turns the eccentrical ring to drive the rotation of the balls to generate induction current in the coils then to be collected by the collecting circuit and provided to the portable electronic device.

Description

technical field [0001] The invention relates to a self-generating device and a portable electronic device using the self-generating device. Background technique [0002] Portable electronic devices, such as mobile phones and MP3 players, are favored and adopted by more and more people due to their light and small size, portability and ease of use. These devices mainly use rechargeable batteries as the power source. Due to the limited capacity of rechargeable batteries and the fast power consumption of portable electronic devices, recharging is often required. [0003] The most important charging method for portable electronic devices is to use a charger to connect to an external power source to charge. Due to the need for an external power source, this method cannot be used outdoors where there is no power source. [0004] The prior art also provides self-powered devices that mainly utilize wind energy, solar energy, and mechanical energy to generate electricity. When this...
