BACKGROUND OF THE INVENTION  
       [0001]     1. Field of the Invention  
         [0002]     The invention relates to an electronic device, and more particularly, to an electronic device having a jacket attracted to the main body.  
         [0003]     2. Description of the Prior Art  
         [0004]     As information technology has increasingly become digital, electronic devices have developed rapidly. Additionally, as digital technology has become prevalent, hand-held devices have become more and more portable. Examples of such hand-held devices are MP3 (Moving Picture Experts Group, MPEG1, layer 3) players, personal disks, etc.  
         [0005]     Please refer to  FIG. 1 .  FIG. 1  is a diagram of a related art portable electronic device  100 . According to  FIG. 1 , the portable electronic device includes a USB interface connector  110  for connecting the device with a main machine (such as a computer). This allows electronic information to be transmitted from the computer to the portable electronic device  100 . Electronic information can also be transmitted from the portable electronic device  100  to the computer via the same route. The portable electronic device  100  is popular with users because of its volume. However, when utilized in a non-static environment, the portable electronic device  100  may be unstable. For example, the electronic device  100  can be securely placed in a static environment, but when it is utilized in a non-static environment (e.g. jogging, walking, dancing) it needs careful attention to prevent the electronic device  100  from falling, and therefore becomes burdensome to the user.  
       SUMMARY OF THE INVENTION  
       [0006]     One objective of the claimed invention is therefore to provide an electronic device having a jacket attracted to the main body, which can be attached to all kinds of fittings such as clothing, hats, or backpacks to solve the above-mentioned problem.  
         [0007]     According to an exemplary embodiment of the claimed invention, an electronic device having a jacket attracted to the main body is disclosed. The electronic device comprises a main body for executing functions of the electronic device; and a jacket having a first end coupled to the main body and a second end attracted to the main body through a magnetic force. The material of one side of the main body&#39;s housing is metal; the second side end of the jacket comprises a magnetic element, and there is a strong magnetic force between the two sides.  
         [0008]     It is an advantage of the present invention that the magnetic force between the main body and the jacket can enable any kinds of fittings to be attached to the electronic device, whilst fulfilling the requirement for a user in a non-static state of not dropping the electronic device.  
         [0009]     These and other objectives of the present invention will no doubt become obvious to those of ordinary skill in the art after reading the following detailed description of the preferred embodiment that is illustrated in the various figures and drawings.

     DETAILED DESCRIPTION  
       [0014]     Please refer to  FIG. 2 ,  FIG. 3  and  FIG. 4 .  FIG. 2 ,  FIG. 3  and  FIG. 4  are the front view, rear view and side view respectively of the present invention electronic device  200 . The electronic device  200  is a hand-held device comprising a main body  210  and a jacket  220 . The main body  210  is for executing functions of the electronic device  200 . For example, the main body  210  can bean MP3 player or a personal disk. The jacket  220  has a first end  230  and a second end  240 . The first end  230  is connected to the main body  210 , and the second end  240  is attracted to the main body  210  through a magnetic force. Please note that the magnetic force is larger than the weight of the electronic device  200 .  
         [0015]     The jacket  220  further comprises a first surface  270  and a second surface  280 . The surface  270  is close to the first end  230  and connected to a corresponding side of the main body  210 . The second surface  280  is close to the second end  240  and connected to another corresponding side of the main body  210 . The first surface  270  and the second surface  280  of the main body  210  can both be flat surfaces or curved surfaces in order to connect. The generated magnetic force when the first surface  270  and the second surface  280  are both curved surfaces is larger than the generated magnetic force when the first surface  270  and the second surface  280  are both flat surfaces. Additionally, the jacket  220  further comprises a spacing part  260  connected to the first surface  270  and the second surface  280  for hanging the electronic device by the joining of a rope or a chain. Therefore the electronic device  200  can be easily hung on a user&#39;s body. The second end  240  further comprises an input/output surface  290 , which is electrically connected through the first end  230  to the main body  210 . The input/output surface could be a USB surface or other kinds of input/output surfaces.  
         [0016]     In the first embodiment of the present invention electronic device  200 , the housing side  250  of the main body  210  is metal, and the second end  240  of the jacket  220  comprises a magnetic element such as a magnet. There is therefore a strong magnetic force between the side  250  and the second end  240 . If a user places a fitting such as clothing, a hat, or a backpack between the side  250  and the second end  240 , the electronic device  200  will be strongly attracted to the user&#39;s fitting through the strong magnetic force.  
         [0017]     In the second embodiment of the present invention electronic device  200 , the main body  210  comprises a magnetic element such as a magnet, and the second end  240  of the jacket  220  comprises a metal element such as an iron sheet. The magnetic element of the main body  210  and the metal element of the second end  240  are therefore attracted to each other through a magnetic force. As in the first embodiment, if a user places a fitting such as clothing, a hat, or a backpack between the side  250  and the second end  240 , the electronic device  200  will be strongly attracted to the user&#39;s fitting through the strong magnetic force.  
         [0018]     In the third embodiment of the present invention electronic device  200 , the housing side  250  of the main body  210  is magnetic, and the second end  240  of the jacket  220  comprises a magnetic element such as a magnet. There is therefore a strong magnetic force between the side  250  and the second end  240 . If a user places a fitting such as clothing, a hat, or a backpack between the side  250  and the second end  240 , the electronic device  200  will be strongly attracted to the user&#39;s fitting through the strong magnetic force.  
         [0019]     In the fourth embodiment of the present invention electronic device  200 , the main body  210  comprises a magnetic element such as a magnet, and the second end  240  comprises another magnetic element such as a magnet. The magnetic elements in the main body  210  and the second end  240  are therefore attracted to each other through a magnetic force. If a user places a fitting such as clothing, a hat, or a backpack between the side  250  and the second end  240 , the electronic device  200  will be strongly attracted to the user&#39;s fitting through the strong magnetic force.  
         [0020]     Please note that the first embodiment uses a metal material (in the main body  210 ) and a magnetic element (in the jacket  220 ) to generate the needed magnetic force; the second embodiment uses a metal element (in the jacket  220 ) and a magnetic element (in the main body  210 ) to generate the needed magnetic force; the third embodiment uses a metal element (in the jacket  220 ) and a magnetic material (in the main body  210 ) to generate the needed magnetic force; and the fourth embodiment uses two magnetic elements (both in the main body  210  and the jacket  220 ) to generate the needed magnetic force. The type of magnetic force between the second end  240  of the jacket  220  and the main body  210  is not limited, however. Any kind of magnetic force can be applied between the second end  240  of the jacket  220  and the main body  210  in order to provide attraction between the jacket  220  and the main body  210 .  
         [0021]     Compared to the prior art, the present invention through the magnetic force between the main body and the jacket can allow a user to be in motion without dropping the electronic device.  
         [0022]     Those skilled in the art will readily observe that numerous modifications and alterations of the device and method may be made while retaining the teachings of the invention. Accordingly, the above disclosure should be construed as limited only by the metes and bounds of the appended claims.
