[Prior Art] Portable electronic devices, such as mobile phones, Mp3, etc., are popular and adopted by more and more people because of their small size, portability, and ease of use. These devices mainly use rechargeable batteries as the power source. Due to the limited capacity of the rechargeable battery and the fast power consumption of the portable electronic device, it is often necessary to charge. The most important charging method for portable electronic devices is to use an external external power supply for charging. This method cannot be used in places where there is no power outdoors because it requires an external power supply. In the prior art, a self-powered device that mainly utilizes wind energy, solar energy, and mechanical energy to generate electric power is also provided. When the self-powered device is used, the portable electronic device is not controlled by the external power source. However, the mechanism required for self-powered devices to generate electricity using hurricane energy is large, and the use of solar power to generate electricity depends on the size of the solar panel. The area requirements are quite high and it is not easy to make small. Therefore, it is not practical to apply the above self-powered device to a thin and portable portable electronic device. Even in a portable electronic device, the volume of the portable electronic device is greatly increased, and the portable electronic device is small and light. At present, the self-powered device uses mechanical energy to supply power to the portable device. A handle is disposed outside the portable device. The user rotates or presses the handle to drive the self-powered device disposed inside the portable device to convert 6 1306918 electric energy to the portable device, but The handles disposed outside the portable device not only affect the aesthetics of the portable device, but also affect the settings of the buttons, interfaces, etc. of the portable device. Especially for some short and small portable electronic devices, such as some music playback devices, it is not suitable to provide a handle for the user to manually generate electricity. The Continental Intellectual Property Office of China has published a self-generating flashlight in 022嶋6.9, which was issued in the January 1st, 2001. The self-powered electric flashlight cylinder is provided with a hollow sleeve body, and a wire ring is arranged on the outer peripheral surface of the sleeve, and a magnetic component is arranged in the sleeve body, and the magnetic component moves in the sleeve body along the axial direction of the sleeve body to generate an induced current in the coil. This self-generating device, due to the axial motion design, stops the movement of the flashlight when the user stops shaking the flashlight. In addition, the axial motion design makes it possible for some short portable devices, such as some music players. Not applicable. SUMMARY OF THE INVENTION In order to provide a self-generating device and a portable electronic device for manufacturing the device, the self-powering device of the self-powering device for power generation can be stopped, and the power generation of the self-generating device is also stopped. The problem. The self-generating device provided by the jin and the portable electronic device using the same also solve the problem that the automatic electric device using the mechanical energy generated in the prior art is not applicable to the short-sized portable electronic device. The self-generating device 'for supplying electric energy to a portable electronic device includes a support ring; an eccentric ring is disposed inside the support ring ring; one or more magnetic balls are fixed on the hem; the support ring Winding outside the loop - or multiple coils - each coil has two nodes; the coil passes through 1306918

請參閱圖2所示。所述自發電裝置2包括一支撐環5， 所述支撐環5固定安裝於便攜式電子裝置1的内部，以使 自發電裝置2固定安裝於便攜式電子裝置1的内部。或者， 所述自發電裝置2置於便攜式電手裝置1的外部時，所述 支撐環5固定於外殼内側。所述支撐環5内部定義有一環 道6。所述環道6内放置有一偏心環7。其中，偏心環7可 與環道6具有同軸心9，亦可與環道6具有不同軸心。當 具有不同軸心時，以偏心環7能在環道6内圍繞環道6軸 心旋轉為限。偏心環7上固定有一磁球8。所述磁球8使 偏心環7重心10位置偏離其軸心9。因此，只有當便攜式 電子裝置1靜止不動或缓慢移動時，偏心環7重心10與其 軸心9的連線處於地球引力的方向，即偏心環7處於一平 衡位置，此時偏心環7不旋轉。當便攜式電子裝置1劇烈 運動（振動）時，帶動偏心環7在支撐環5環道6内圍繞 軸心9旋轉，使偏心環7重心10偏離平衡位置，此時，即 使便攜式電子裝置1停止劇烈運動，偏心環7亦會在自身 重力的作用下為返回平衡位置而圍繞軸心9旋轉。 支撐環5外部環繞一或多個線圈，其中圖2中示出為 圍繞兩個線圈11的情況，該兩個線圈11每個上分別具有 兩節點12，通過該兩節點12將該線圈11連接至一電能收 集電路13。所述電能收集電路13包括一整流電路14、一 濾波電路15以及一儲能電路16。當磁球8在支撐環5環 道6内旋轉時，兩線圈11内產生感應電流，該感應電流經 1306918 整流電路14整流後進入濾波電路15，由該濾波電路15濾 波後進入儲能電路16，在儲能電路16中存儲。其中，該 整流電路14可以為一橋式整流、該濾波電路15可以為一 濾波電容、該儲能電路16可以為一大容量的儲能電容。Please refer to Figure 2. The self-generating device 2 includes a support ring 5 that is fixedly mounted inside the portable electronic device 1 such that the self-generating device 2 is fixedly mounted inside the portable electronic device 1. Alternatively, when the self-generating device 2 is placed outside the portable electric device 1, the support ring 5 is fixed to the inside of the casing. A loop 6 is defined inside the support ring 5. An eccentric ring 7 is placed in the loop 6 . The eccentric ring 7 may have a concentric 9 with the ring 6, or may have a different axis from the ring 6. When there are different axes, the eccentric ring 7 can be rotated within the ring 6 around the axis of the ring 6 to the limit. A magnetic ball 8 is fixed to the eccentric ring 7. The magnetic ball 8 positions the center of gravity 10 of the eccentric ring 7 away from its axis 9. Therefore, only when the portable electronic device 1 is stationary or moving slowly, the line connecting the center of gravity 10 of the eccentric ring 7 and its axis 9 is in the direction of gravity of the earth, i.e., the eccentric ring 7 is in a balanced position, at which time the eccentric ring 7 does not rotate. When the portable electronic device 1 is vigorously moved (vibrated), the eccentric ring 7 is driven to rotate around the axis 9 in the ring 6 of the support ring 5, so that the center of gravity 10 of the eccentric ring 7 is deviated from the equilibrium position. At this time, even if the portable electronic device 1 stops strikingly Movement, the eccentric ring 7 also rotates around the axis 9 for returning to the equilibrium position under the action of its own gravity. The support ring 5 is externally surrounded by one or more coils, wherein the case of surrounding the two coils 11 is shown in FIG. 2, each of which has two nodes 12 on each, through which the coils 11 are connected To a power collecting circuit 13. The power collecting circuit 13 includes a rectifier circuit 14, a filter circuit 15, and a tank circuit 16. When the magnetic ball 8 rotates in the loop 6 of the support ring 5, an induced current is generated in the two coils 11. The induced current is rectified by the rectifying circuit 14 and enters the filter circuit 15, which is filtered by the filter circuit 15 and enters the energy storage circuit 16 Stored in the tank circuit 16. The rectifier circuit 14 can be a bridge rectifier, the filter circuit 15 can be a filter capacitor, and the energy storage circuit 16 can be a large-capacity storage capacitor.

For example, the tank circuit 16 can be connected to the electrical components of the portable electronic device 1 for use as a backup battery. The storage circuit 16 can also be connected to a charging circuit (not shown) of the secondary battery inside the portable electronic device 1, via which the secondary battery is charged. In a further implementation, the tank circuit 16 is further coupled to a monitoring circuit (not shown) that monitors the amount of charge stored in the tank circuit 16 and controls the storage when the charge level in the tank circuit 16 reaches a certain level. The energy circuit 16 charges the secondary battery. Please refer to Figure 3. Fig. 3 is a view showing a case where a plurality of magnetic balls 8 are fixed to the eccentric ring 7. In Fig. 3, six magnetic balls 8' are fixed on the eccentricity 7 and the six magnetic balls 8 are uniformly or non-uniformly distributed on the eccentric ring 7. When uniformly distributed, the six magnetic balls 8 are provided with different weights (i.e., unbalanced weights) such that the center of gravity 10 of the eccentric ring 7 is offset from its axis 9. In the non-uniform distribution, the non-uniform distribution or unbalanced weight of the six magnetic balls 8 or both combines the center of gravity 10 of the eccentric ring 7 from its axis 9. The support ring 5 is externally surrounded by six coils 11, which are connected to the rectifier circuit 14 via their nodes 12, respectively. In the above embodiment, the support ring 5 and the eccentric ring 7 are both in a full ring shape. In other embodiments, the support ring 5 and the eccentric ring 7 may each have a non-full ring shape, such as a half ring shape, and may also support the ring 5 . The full-ring shape and the eccentric ring 7 have a non-full ring shape. 1306918 In the above self-powered device 2 structure, since a simple loop-plus-ball and coil structure is adopted, a compact size can be made in the portable electronic device 1. Further, the eccentric ring 7 inside the self-generating device 2 can continue to rotate around the axis after the self-energizing device 2 stops vibrating, and the remaining kinetic energy is continuously converted into electric energy, which can greatly power the portable electronic device.
