BACKGROUND 
       [0001]    1. Technical Field 
         [0002]    The present disclosure generally relates to earphones, and particularly, to a detachable earphone. 
         [0003]    2. Description of the Related Art 
         [0004]    An earphone generally includes an earplug, an audio plug, and an earphone cable connecting the earplug to the audio plug. However, in use, a joint part of the earplug and the earphone cable, or audio plug and the earphone cable may be easily damaged by pulling or bending of the earphone. Because the earphone cable is soldered to the earplug and to the audio plug, if any one of the earphone cable, the audio plug, and the earplug is damaged, the whole earphone may need to be replaced. Thereby wasting a lot of material for making the earphone. 
         [0005]    Therefore, there is room for improvement within the art.

     DETAILED DESCRIPTION 
       [0010]    Referring to  FIG. 1 , an embodiment of an earphone  100  comprises an audio plug  20 , an earplug  30 , and an earphone cable  40  detachably connected to the audio plug  20  and the earplug  30 . 
         [0011]    Referring to  FIGS. 2 and 3 , the audio plug  20  comprises a metal joint  21 , a first joining portion  23  formed on an end of the metal joint  21 , and a positioning portion  25  formed on an end of the first joining portion  23 , away from the metal joint  21 . The audio plug  20  may be connected to an audio device (not shown). The first joining portion  23  defines a first receiving groove  231 , a second receiving groove  232 , a third receiving groove  233 , a fourth receiving groove  234 , and a fifth receiving groove  235 , all of which are coaxial and interconnected with each other. A diameter of the second receiving groove  232  is larger than that of the first receiving groove  231  and that of the third receiving groove  233 . A diameter of the fourth receiving groove  234  is larger than that of the third receiving groove  233 , and a diameter of the fifth receiving groove  235  is larger than that of the fourth receiving groove  234 . The positioning portion  25  axially defines a positioning hole  251 . 
         [0012]    The earphone cable  40  is made by wrapping a plastic layer on a copper wire. The earphone cable  40  comprises a first insertion portion  41  connected to the audio plug  20 , and a second insertion portion  43  connected to the earplug  30 . Both of the first insertion portion  41  and the second insertion portion  43  have stepped portions. Each of the first insertion portion  41  and the second insertion portion  43  comprise a first connecting portion  411 , a second connecting portion  412 , a third connecting portion  413 , and a fourth connecting portion  414 , all of which are coaxial. A diameter of the second connecting portion  412  is larger than that of the first connecting portion  411  and that of the third connecting portion  413 . A diameter of the fourth connecting portion  414  is larger than that of the third connecting portion  413 . 
         [0013]    In an illustrated embodiment, the first insertion portion  41  and the second insertion portion  43  are formed by grinding. The earphone cable  40  is positioned on a grinding device (not shown), and extends in a straight line. A grinding wheel (not shown) of the grinding device is rotated in a clockwise direction, and the earphone cable  40  is rotated in a counterclockwise direction when the grinding wheel contacts the earphone cable  40 . Therefore, the first insertion portion  41  and the second insertion portion  43  are formed on opposite ends of the earphone cable  40  by the grinding wheel. 
         [0014]    Because the earphone cable  40  is made by wrapping plastic layer on a copper wire, the earphone cable  40  is flexible. The first insertion portion  41  is inserted into the first joining portion  23  of the audio plug  20 , and then the first connecting portion  411  is engaged in the first receiving groove  231 , the second connecting portion  412  is engaged in the second receiving groove  232 , the third connecting portion  413  is engaged in the third receiving groove  232 , the fourth connecting portion  414  is engaged in the fourth receiving groove  234 , and a part of the earphone cable  40  adjacent to the first insertion portion  41  is received in the fifth receiving groove  235  and the positioning hole  251 . The earphone cable  40  may then be electrically connected to the audio plug  20 . When the earphone cable  40  is pulled by a sudden external force, the first insertion portion  41  may be detached from the audio plug  20 , thereby avoiding damaging the earphone  100 . 
         [0015]    Referring again to  FIG. 3 , the earplug  30  comprises a main body  31 , and a second joining portion  33  extending from an end of the main body  31 . The second joining portion  33  has a same shape as the first joining portion  23 . The second insertion portion  43  is inserted into the second joining portion  33 , and then the earphone cable  40  is electrically connected to the earplug  30 . When the earphone cable  40  is pulled by a sudden external force, the second insertion portion  43  may be detached from the earplug  30 , thereby avoiding damaging the earphone  100 . 
         [0016]    The first joining portion  23  and the second joining portion  33  may define two or more receiving grooves, and the first insertion portion  41  and the second insertion portion  43  may form two or more corresponding connecting portions. In addition, the first joining portion  23  and the second joining portion  33  may have different structures. The first joining portion  23  and the second joining portion  33  may be formed on opposite ends of the earphone cable  40 , and the first insertion portion  41  and the second insertion portion  43  may be formed on the audio plug  20  and the earplug  30 . Furthermore, the earphone cable  40  may be fixedly connected to one of the audio plug  20  and the earplug  30 , and detachably connected another one of the audio plug  20  and the earplug  30 . 
         [0017]    When any of the audio plug  20 , the earplug  30 , and the earphone cable  40  is damaged, a user may only need to replace a damaged part of earphone  100 , instead of replacing the whole earphone  100 , because the audio plug  20 , the earplug  30 , and the earphone cable  40  are detachably connected. When the earphone cable  40  is pulled by a sudden external force, the first insertion portion  41  may be detached from the audio plug  20 , or the second insertion portion  43  may be detached from the earplug  30 , thereby avoiding damaging the earphone  100 . 
         [0018]    While the present disclosure has been described with reference to particular embodiments, the description is illustrative of the disclosure and is not to be construed as limiting the disclosure. Therefore, various modifications can be made to the embodiments by those of ordinary skill in the art without departing from the true spirit and scope of the disclosure, as defined by the appended claims.
