Portable electronic devices such as mobile phones, small notebook computers and MP3 players are invented and widespread, people can use the mobile phone to deal with various affairs or enjoy music via the MP3 player while marching. 
     Taking the mobile phone as an example, when a user uses the mobile phone to contact a person, the user generally holds the mobile phone by his/her hand, so that an earphone and a voice receiver can be located near his/her ear and mouth for the user to clearly hear the voice from a counterpart and send his/her own voice to another counterpart. However, the user still has to use his/her hand to hold the mobile phone, and if the user is driving a car or both hands of the user are not available, it is inconvenient for the user to use the mobile phone. 
     Presently, wireless earphones (such as bluetooth earphones) are widely used for receiving audio information. Since the bluetooth earphone is communicated with the mobile phone through a wireless approach, it is unnecessary to connect a transmission line between the mobile phone and the bluetooth earphone, and the bluetooth earphone can be directly worn on the ear of the user. Therefore, it is unnecessary for the user to hold the mobile phone when the bluetooth earphone is utilized. 
     Since the bluetooth earphone has advantages of small size and light weight, when the bluetooth earphone is not used, the user probably puts it in a carry bag or other places. However, when the user wants to use the bluetooth earphone, the user has to rummage it from the carry bag, which can be inconvenient for using. Moreover, when the user fetches other stuffs from the carry bag, the bluetooth earphone can be carelessly taken out at the same time, so that the bluetooth earphone can probably fall out of the carry bag and can be lost, or the bluetooth earphone can be lost in somewhere due to a careless placement. Moreover, since a size of the bluetooth earphone is very small, a battery power thereof is probably inadequate, and replacing of the battery is difficult. Therefore, using of the bluetooth earphone has the above inconveniences.

     DESCRIPTION OF THE EMBODIMENTS 
       FIG. 1  is a schematic diagram illustrating an electronic device according to an embodiment of the present invention. Referring to  FIG. 1 , the electronic device  100  includes a body  110  and an earphone  120 . The body  110  is, for example, a mobile phone, a small notebook computer or a MP3 player, etc., and the earphone  120  is, for example, a wireless earphone, such as a bluetooth earphone, etc. without a physical transmission line. One end  112  of the body  110  has an earplug-accommodating opening  114  and a power-supplying terminal  116 . The earphone  120  has an earplug  122  and a power-charging terminal  124 . The earplug  122  is accommodated in the earplug-accommodating opening  114 , and the power-charging terminal  124  is electrically connected to the power-supplying terminal  116 . The earphone  120  can be assembled to the body  110  by accommodating the earplug  122  in the earplug-accommodating opening  114 , so as to avoid a situation that the earphone  120  cannot be found due to a careless placement of the earphone  120 . Moreover, the earphone  120  can also be charged by a power of the body  110 . 
     In the present embodiment, the end  112  further has a first fixing structure  118 , and the earphone  120  has a second fixing structure  126 , wherein shapes of the first fixing structure  118  and the second fixing structure  126  are complementary, so that the first fixing structure  118  and the second fixing structure  126  can be mutually fit.
