BACKGROUND OF THE INVENTION  
       [0001]     1. Field of the Invention  
         [0002]     The present invention relates to an adjusting member for cable, and particularly to an adjusting member for earphone cable.  
         [0003]     2. Description of Prior Arts  
         [0004]     Today, people need more information to communicate with each other frequently. So, many portable electronic equipments, such as the walkman, MP3, handset and other sound players, become an important part in people&#39;s life. Usually, an earphone is used on the music player or handset. Accordingly, there are many different kinds of earphone. One kind of earphone is circumaural earphone. The strip of the circumaural earphone bestrides the head and the earphone extrudes the ears of a user. However, the structure of the circumaural earphone makes the user feel uncomfortable and take it inconveniently.  
         [0005]     And then, another type of earphone is popular with people, it is the insert type earphone. One end of the insert earphone is an earphone inserted into the ear of the user directly, and the other end of the insert type earphone is connected to the music player or handset by a plug. Then we can use the insert type earphone conveniently at any time, the insert earphone is light and convenient to take.  
         [0006]     The conventional adjusting member for cable is a ball having a receiving channel. The earphone cable is received in the channel, and then the ball can slide along the cable to adjust the length of the earphone cable. The ball is fixed on the cable by the force friction between the cable and the inner surface of the channel. However, the structure of the ball is too simple to adjust the length of the cable, as the ball being slid up and down the friction-free between the cable and the inner surface of the channel will become less and less, then the force friction would be not enough to make the ball to adjust the length of the earphone cable.  
         [0007]     Obviously, we need a new adjusting member for cable, which could adjust the cable stably and efficiently.  
       SUMMARY OF THE INVENTION  
       [0008]     An object of the present invention is to provide an adjusting member to adjust the length of the earphone cable efficiently.  
         [0009]     To achieve the above object, an adjusting member assembles to a cable, it defines at least one cavity to receive the cable, and the adjusting member can adjust the length of the earphone cable by sliding and fixing on the cable, it comprises: a first half body, defining a first cavity; and a second half body, defining a second cavity; wherein the first half body is assembled to the second half body thereby forming the adjusting member. The first cavity and the second cavity form together a cavity to receive the cable, which extend through the adjust member. The first cavity and the second cavity are defined eccentrically, when the first half body and the second half body are assembled.  
         [0010]     An adjusting member assembles to a cable, it defines at least one cavity to receive the cable, and the adjusting member can adjust the length of the earphone cable by sliding and fixing on the cable, it comprises: a first half body made of soft material, defining a first cavity and a channel; a second half body made of hard material, defining a second cavity and a pin, and the dimension of the pin is larger than the channel; wherein the first half body is assembled to the second half body, the first cavity and the second cavity form a cavity to receive the cable, which extends through the adjust member. The pin is inserted into the channel to drive the inner side of channel to distort inwardly when the first and second half body are assembled.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT  
       [0019]     Referring to  FIGS. 1 and 2 , the present invention relates to an adjusting member  1  for assembling to a cable  2 . The cable  2  includes an earphone cable  21  and a connecting cable  22 . The free end of the earphone cable  21  has an earphone (not shown), and the connecting cable  22  connects to electronic equipment  3 . The electronic equipment  3  can be the common audio plug or the USB interface, as it is used in different situation. Wherein, the earphone cable  21  electrical connects to the connecting cable  22  by corresponding signal wire.  
         [0020]     As shown in  FIGS. 3 and 4 , the adjusting member  1  comprises a first half body  11  and a second half body  12 . The first half body  11  includes a first grasping portion  111 , a pair of channels  112 , a first cavity  113  for receiving an earphone cable, a first passageway  114  for receiving a connecting cable and a first touching surface  115 . The second half body  12  includes a second grasping portion  121 , a pair of pins  122 , a second cavity  123  for receiving an earphone cable, a second passageway  124  for receiving a connecting cable and a second touching surface  125 .  
         [0021]     Referring to  FIG. 3-5 , as the first half body  11  assembling to the second half body  12 , the pins  122  of the second half body  12  are inserted into the channels  112  of the first half body  11 , and the first touching surface  115  overlaps with the second touching surface  125 . The earphone cable  21  extends through the cavity (not labeled) consisted of the first cavity  113  and the second cavity  123 , and the connecting cable  22  extends through the passageway consisted of the first passageway and the second passageway. The first cavity  113  and the second cavity  123  are eccentric after the first half body  11  and the second half body  12  are assembled, and so are the first rib  116  and the second rib  126 . That means the first cavity  113  and the second cavity  123  having the axis located elsewhere than at the geometric center. The aperture of the cavity at the junction plane (not labeled) between the first cavity  113  and the second cavity  123  is smaller than the first cavity  113 . So the earphone cable  21  will be engaged by the inner surface of the cavity at the junction plane, and then the adjusting member could fix on the cable  2 . However, the junction plane will disappear after the first half body  11  and the second half body  12  are separated from each other. So, the adjusting member  1  could fix or slide on the cable  2  by assembling or separating the first half body  11  and the second half body  12 , so as to adjust the length of the earphone cable  21  of the cable  2 .  
         [0022]     Referring to  FIG. 6  and  FIG. 7 , it is the second embodiment of the adjusting member. The adjusting member  6  includes a first half body  61  and a second half body  62 . The first half body  61  includes a first grasping portion  611 , a pair of channels  612 , a first cavity  613  for receiving an earphone cable, a first passageway  614  for receiving a connecting cable, a first touching surface  615  and a first rib  616 . The second half body  62  includes a second grasping portion  621 , a pair of pins  622 , a second cavity  623  for receiving an earphone cable, a second passageway  624  for receiving a connecting cable, a second touching surface  625  and a second rib  626 . The adjusting member  6  is similar to the said adjusting member  2  in structure, and the difference between said two is that the first cavity  613  and the second cavity  623  are not eccentric after the first half body  61  and the second half body  62  are assembled, and so are the first rib  116  and the second rib  126 .  
         [0023]     The first half body  61  is made of softer material than the second half body  62 . The dimension of the pin  622  is bigger than the dimension of the channel  612 . When the first half body  61  and the second half is assembling the bigger and harder pin  622  of the second half body will insert into the softer and smaller channel  612  of the first half body, then the channel  612  will be expended because of the pin  622 . The aperture of the cavity and the passageway will be reduce because of the expended channel  612 , and then the inner surfaces of the cavity and the passageway will engage with the earphone cable  21  and the connecting cable  22  received in the cavity and the passageway. However the aperture of the cavity and the passageway will restore after the first half body  61  and the second half body  62  are separated from each other. So, the adjusting member  6  also could fix and slide on the cable  2  by assembling and separating the first half body  61  and the second half body  62 , so as to adjust the length of the earphone cable  21  of the cable  2 .  
         [0024]     The said two embodiment of adjusting member could adjust the cable, only included the earphone cable. In this case, it only needs one adjusting member. Two earphone cables will be received into the cavity, and then, the adjusting member may adjust the free end of the earphone from sliding on the cable up and down.  
         [0025]     It is to be understood, however, that even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
