     FIELD OF THE INVENTION 
       [0002]    The present invention relates to connecting seat, and particular to a speaker connecting seat for conducting speaker signals. 
       DESCRIPTION OF THE PRIOR ART 
       [0003]    Speakers are developed by advanced electronic audio technology for transforming electric signals to sounds. It is also an important component to output sounds for electronics such as earphone, stereo system, communication equipment, multimedia computer, electronic translator, and equipments for transmitting or transforming sound signals. The electric signals can be processed by a main frame into phases such as high pitch, low pitch, mono or stereo sound, and others. Audiences usually use various main frames connected by connectors or terminals for different signals to output sounds through a same set of speaker. 
         [0004]    While a lot of sound terminals are connected to the speaker, a corresponding quantity of connector is needed. It is complicated and causes higher cost, and it also damages an outer appearance for such circumstance. A jumper is needed for connecting various sets of positive and negative terminals. Such jumper will cause higher impendence for signal transmission and sound distortions will thus happened. 
         [0005]    Therefore, the inventor of the present invention once provided a Taiwan patent with application no. 096128495 and published no. 200908483 about a connecting device capable of switching between a single conduction and multi-conduction by a single fixing cap. The invention has a main body of cable connecting seat for an electronic equipment. The main body is an assembly consisting of fixing cap and socket. The assembly has three main portions. The first portion is cable connecting portion having threaded socket for fixing cable by directly insertion or with the fixing cap. An end of the fixing cap is conductive end and the other one is an insulated end so as to perform a single conduction or separated conduction by turning the fixing cap. The second portion is conducting portion consisting of at least two sets of device with an insulator between. The device has an end contacting the cable and locking the fixing cap and another end connecting the electronic equipment attached to the invention. When a cable is conducted to the conducting portion and the conductive ends of the fixing cap, various conducting portions will be conducted to the same cable through the conductive ends of the fixing caps conducted together. On the contrary, when different cables are connected to each conducting portion and the insulated end of the fixing caps, the cables will be conducted to each conducting portion separately. The third portion is attaching portion serving to attach the invention to a proper position of a stereo system. The invention will be fixed by a engaging unit so that it will not be moved while plugging or unplugging cables. 
         [0006]    Based on the mentioned patent, a China patent of no. 200810134454.2 and a U.S. Pat. No. 12176449 are applied. Although the mentioned patents have superior functions, there is improvement remained to develop about the simplification of components. 
       SUMMARY OF THE PRESENT INVENTION 
       [0007]    Accordingly, a speaker connecting seat according to the present invention includes a retainer. Separated tunnels are formed inside the retainer for respectively receiving a first conducting component and a second conducting component. The first conducting component is extended to a first end portion of the rod body and is thus connected to a connecting portion. The second conducting component is extended to the first end portion of the rod body and is thus formed as a contacting sheet. An adjusting sleeve have a through tube body. An insulated ring and a conductive ring are respectively arranged to two ends of the adjusting sleeve. By selectively connecting one of the two ends of the adjusting sleeve to the contacting sheet of the second conducting component, the adjusting sleeve can be slid into the connecting portion of the first conducting component so as to conveniently switch a conducting path. 
         [0008]    The separated tunnels formed inside the retainer allow two independent signals transmitted through the first conducting component and the second conducting component so as to save spaces and improve an outer appearance of a stereo system. 
         [0009]    Moreover, a blocking sheet is arranged to an inner wall of the adjusting sleeve for providing a compressing force to the inserted connecting portion so that the stability of the connection as well as the sound transmission are improved. Also, the blocking sheet can prevent damage to the system by avoiding accidental plug of unnecessary cable to a same path. 
         [0010]    The blocking sheet of the present invention not only serves to compressing the connecting portion but also stabilize the transmitted signal. For such definitions and purposes, the shape and mechanism of the blocking sheet are not confined within a specific style.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0021]    In order that those skilled in the art can further understand the present invention, a description will be provided in the following in details. However, these descriptions and the appended drawings are only used to cause those skilled in the art to understand the objects, features, and characteristics of the present invention, but not to be used to confine the scope and spirit of the present invention defined in the appended claims. 
         [0022]    Referring to  FIGS. 1 and 2 , a speaker connecting seat includes the following components. 
         [0023]    A retainer  1  consists of a rod body  11  made of an insulated material. A rear end of the rod body  11  has a thread  113 . With reference to  FIGS. 4 and 5 , a first tunnel  111  and a second tunnel  112  are formed inside of the rod body  11 . A first conducting component  121  and a second conducting component  122  are arranged to the first tunnel  111  and a second tunnel  112  respectively. The two tunnels  111  and  112  are separated from each other so that the first conducting component  121  and the second conducting component  122  are capable of conducting it&#39;s own signal independently within the retainer  1 . Space for wiring is saved so as to improve an outer appearance of a stereo system. 
         [0024]    However, the first conducting component  121  is extended to a first end portion  110  of the rod body  11  and is thus connected to a connecting portion  121 A. An outer end of the connection portion  121 A has a socket  121 D for receiving an external terminal as shown in  FIG. 5 . The connecting portion  121 A serves to connect and conduct for the first conducting component  121 . The second conducting component  122  is extended to the first end portion  110  of the rod body  11  and is thus formed as a contacting sheet  122 A. The contacting sheet  122 A can be shaped corresponding to the first end portion  110  of the rod body  11 . The contacting sheet  122 A serves to connect and conduct for the second conducting component  122 . 
         [0025]    An adjusting sleeve  2  has a through tube body  25 . An insulated ring  21 A and a conductive ring  22  are arranged to two ends of the adjusting sleeve  2  respectively. The two ends of the adjusting sleeve  2  can be selectively faced to the contacting sheet  122 A of the second conducting component  122 . The insulated ring  21 A is preferably formed by an insulated piece  21  inserted into the tube body  25  so that an outer end of the insulated piece  21  is formed as an insulated ring  21 A. In another embodiment of the present invention which is not shown in the Figures, an insulated attachment is attached to the end of the tube body  25  instead to form a said insulated ring. 
         [0026]    The second conducting component  122  and the conducted signal are isolated by sliding the adjusting sleeve  2  into the rod body  11  with the insulated ring  21 A contacting the contacting sheet  122 A of the second conducting component  122 . The signal will be transmitted only through the connecting portion  121 A of the first conducting component  121  to an external plugged male terminal  3  and a cable  4  connected to the male terminal  3 . Referring to  FIG. 8 , the contacting sheet  122 A of the second conducting component  122  will be conducted to other cable  6  through a Y-terminal  5  under compression by the insulated ring  21 A of the adjusting sleeve  2 . 
         [0027]    While the second conducting component  122  and the first conducting component  121  are needed to conduct to a same single cable, the adjusting sleeve  2  is slid into the rod body  11  with the conductive ring,  22  contacting the contacting sheet  122 A of the second conducting component  122 . A signal source from a Y-terminal  5  of a cable  6  can be conducted to the contacting sheet  122 A of the second conducting component  122  by inserting the Y-terminal  5  into a gap between the conductive ring  22  and the contacting sheet  122 A as shown in  FIGS. 6 and 7 . Or, with reference to  FIGS. 4 and 10 , the cable  4  with the male terminal  3  conducted to the connecting portion  121 A extending from the first conducting component  121  can be conducted to the first conducting component  121  and the second conducting component  122 . Therefore, the first conducting component  121  and the second conducting component  122  can be conducted to the cable  6  or the cable  4  in the same time. 
         [0028]    The first conducting component  121  and the second conducting component  122  can be differently shaped for different shapes of the first tunnel  111  and a second tunnel  112 . Referring to  FIG. 3 , the first conducting component  121  is flat so that the first tunnel  111  is also formed flat. While in  FIG. 4 , the first tunnel  111  inside the rod body  11  is bent but the second tunnel  112  is straight. 
         [0029]    Furthermore, with reference to  FIG. 1 , a preferable embodiment of the connecting portion  121 A of the present invention is shown. An outer thread  122 B is formed to an outer surface of the connecting portion  121 A, and a corresponding inner thread  20  is formed to an inner wall of the adjusting sleeve  2  as shown in  FIG. 4 . The connecting portion  121 A also can be a simple bolt capable of directly inserting into the adjusting sleeve  2 . 
         [0030]    Moreover, the inner thread  20  of the adjusting sleeve  2  can be formed to an inner wall of the conductive ring  22  (as shown in  FIG. 6 ) or an inner wall of the insulated piece  21 . The inner thread  20  can be formed without extra work to the adjusting sleeve  2 , the manufacturing process will thus be simplified and the cost is also saved. Obviously, the inner thread  20  can be also formed directly to an inner wall of the adjusting sleeve  2  as shown in  FIG. 7 . 
         [0031]    With reference to  FIGS. 6 and 7 , a first blocking sheet  23 A is pivoted to an inner wall  24  of the adjusting sleeve  2 . The first blocking sheet  23 A serves to block an external cable from plugging into the connecting portion  121 A of the first conducting component  121  while a cable is already conducted to the gap D between the conductive ring  22  and the contacting sheet  122 A so as to prevent accidental damage to the system. Referring to  FIGS. 4 and 10 , while the conductive ring  22  of the adjusting sleeve  2  is pushed to contact the contacting sheet  122 A of the second conducting component  122  without having another cable connected the gap D between the conductive ring  22  and the contacting sheet  122 A, the connecting portion  121 A extending from the first conducting component  121  will push the blocking sheets  23 A and  23 B away so as to allow a cable to plug in. The plugged cable will be conducted to the connecting portion  121 A of the first conducting component  121  and also the second conducting component  122  through the conductive ring  22 . 
         [0032]    In  FIG. 8 , a reverse installation of the adjusting sleeve  2  is shown than that in the  FIGS. 7 and 6 . With reference to  FIG. 5 , the blocking sheets  23 A and  23 B are formed as curves. The blocking sheets serve to block or receive depending on the positions of the connecting portion  121 A, the blocking sheets can be made of elastic material or it can be pivoted to achieve such purpose. The shape and mechanism of the blocking sheets of the present invention are not confined within a certain type. 
         [0033]    With reference to  FIG. 9 , an embodiment of the contacting sheet  122 A extending from the second conducting component  122  is illustrated. The contacting sheet  122 A is formed as approximate C shape, and the second conducting component  122  is extended from a portion of an inner fringe of the ring. The contacting sheet  122 A can also be a ring with a cut and the second conducting component  122  is extended from a fringe of the cut as shown in  FIG. 1 . The shape of the contacting sheet  122 A can be various but it is preferably corresponding to that of the conductive ring  22  and the insulated ring  21 A. 
         [0034]    Referring to  FIGS. 10 and 7 , another embodiment of the connection between the first conducting component  111  and the connecting portion  121 A are illustrated. The connecting portion  121 A is hollow, and the first conducting component  121  is inserted into the hollow portion of the connecting portion  121 A. An elastic curved portion of the first conducting component  121  is exposed outside the connecting portion  121 A so as to contact the conductive ring  22  of the adjusting sleeve  2 . The conductive ring  22  can be replaceable by a better conductive material or structure capable of controlling voltage and current by the needs. Referring to  FIG. 10 , a free end of the first conducting component  111  forms an opening  111 B, a tunnel  111 C is extended inwards from the opening  111 B for receiving and conducting a terminal  3  plugged from the opening  111 B so as to ensure the stability of the terminal as well as the signal carried by the cable connected to the terminal. Referring to  FIG. 7 , while the conductive ring  22  of the adjusting sleeve  2  is pushed to contact the contacting sheet  122 A of the second conducting component  122  without having another cable connected the gap D between the conductive ring  22  and the contacting sheet  122 A, the connecting portion  121 A extending from the first conducting component  121  will move further inwards to push the blocking sheets  23 A and  23 B away so as to allow a terminal to plug. The plugged terminal will be conducted to the connecting portion  121 A of the first conducting component  121  and also the second conducting component  122  through the conductive ring  22 . Preferably, the blocking sheets  23 A and  23 B symmetrical arranged on the inner wall  24  of the adjusting sleeve  2  will provide symmetric suppressing forces to the received connecting portion  121 A so as to have better stability between the adjusting sleeve  2  and the connecting portion  121 A. 
         [0035]    The present invention is thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the present invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
