And a connector for connecting the audio output terminal. [Prior technology] Ge: = _, the national needs for her diversification == This prompted the audio-visual equipment market to flourish: and the various types of video = one of the indispensable equipment. The conventional speaker must have several connectors. Each of the connectors is exposed outside the speaker, and the source is outputted by the source of the = connection-domain (such as -amplifier), so that the host can send the stalk to the source. The female speaker, which in turn makes a sound. Further, the shape of the sound source output terminal is generally U-shaped or pointed cylindrical. Referring to FIG. 1, the connector 9 of the conventional speaker includes a conductive member 91 and a cap 92. The conductive member 9 is a screw, and one end thereof is connected to a wire 911. The conductive member 91 has an outer-outer flange 912 formed on the outside, and the first-outer flange 912 is interposed between the two ends of the conductive member 91. The cap 92 includes an insulator milk, a through-hole milk, and a conductive portion 923 ′. The through hole 922 extends through the two ends of the insulator 921. The end of the conductive portion 923 forms a second outer flange. The conductive portion 923 Embedded in and tightly fitted to one end of the through hole 922, the second outer flange 924 is exposed to the insulator 92 and closely attached to the end of the insulator 921, and the inner side wall is formed with an internal thread. The coffee cover 9 is electrically conductive 91. Furthermore, the connector of the conventional speaker is connected to the external source of the audio source (four), and the connector 9 utilizes the first--, when the conventional speaker H wants to connect the number of sound sources of the four sources to match the source. The number of output terminals, the speaker must be equipped with four connectors 9 in the middle. On the other hand, as shown in FIG. 2, when a host has only one audio source output positive rui (10) and a sound _ outgoing negative terminal, and the conventional yangsheng & _ pre-set number four is the connector 9, the four connections Two of the sockets 9 are respectively connected to the sound source output positive/negative terminals (10), and the other two of the four connector bases 9 must use the second jumper 31 to divide and connect the sound source to output positive/negative rui. The connectors 9 are connected to each other. The jumper 310* increases the noise of the material source, and its impedance and itself 4 have doubts about degraded sound quality' and the volume of the jumper (10) is very small, and the external force is deformed, and the system also allows the stomach to It is lost, causing inconvenience in use. SUMMARY OF THE INVENTION An object of the present invention is to provide a connector structure for a speaker that can connect a single-sound source output/terminal without a scale arrangement, or simultaneously connect a two-tone source output neutron. The connector structure of the speaker of the present invention: a conductive member, a second conductive member, an insulating member, and a cap. The first conductive member comprises a first body and a body of the rod; the second conductive member is coupled to: the opening of the insulating member is an insulator and is interposed between the first conductive member and the rubber: the insulating member 4 is Made of insulating material, material. The insulating member 4 includes a first edge member 4_a conductor 21: a guiding portion of the member 3: when avoiding == 311, the first guiding system is also contacted by the second half (four) ι/·1 ' The insulating member 4i is mainly used for reinforcing the stability of the first conductive member 2 and the first portion, and the second conductive member 3 is prevented from contacting the first combined retaining member 5 for fixing the first conductive member 2. 3, and the first V component of the insulating member 4 is opposite to the first component, the conductive member 2 and the second conductive member can be combined with each other; and, in order not to lead the third insulating member 3 Γ Short-circuited 'The positioning member 5 is made of wood. The first money member 2 and the second conductive member 3 can be independent two conductive members of the connector of the present invention, and the two conductive members are each connected to a wire 23, 32. The positioning member 5 is formed by the combination of the two half-rings 51, and each of the semi-bad bodies 51 includes a body 511, a column 512 and a positioning hole 513. The end of the e-body body 511 is formed with a groove 514 for the guiding portion 311 to be placed, and the other end of the body 511 is formed with a convex portion 515. The inner side wall of the body 511 protrudes from the column 512. As shown in Fig. 4, the column 512 is inserted into the locking hole 312 and abuts against the rod body. The position hole 513 extends through the body 511 and the column 512, and corresponds to the first through hole 22 and the positioning member 5 can lock the first conductive member 2 and the second portion by using a screw 52 and a nut 53. Conductive member 3 and insulating member 4. Further, as shown in the third and fourth figures, the fixing member 6 is sleeved on the second conductive member 3 and includes a "first" fixing member 6 - a second fixing member 62 and a spacer 63. The first 囡~1 forms a convex portion 611 from one end of the C11^ angstrom element 61, and the convex portion 611 faces the convex portion 515 of the fixing member 5 for clamping a speaker outer casing 7 . The potential spacer 63 is interposed between the first fixing member 61 and the first fixing member 62. Further, the minute and the sound a.. 5 keling wire 32 is provided between the second fixing member 62 and the spacer 63. As shown in the figure 2, the first embodiment of the present invention uses a two-sound source wheel terminal to connect the speaker to the speaker; at this time, the input of _彡峨魄1 is directed to the The guiding portion 311 is connected to the first conductive member 2. Please refer to the soil map. The second implementation of the present invention uses a main unit, a main unit, and a wheel to connect a speaker. At this time, the hat of the middle cover 1 is used. The body 11 is inwardly directed toward the guiding portion of the second conductive member 3 to invent the ttn conductive member 2°, wherein the speaker only needs to be set to perform the following steps: as shown in Fig. 6, the main body, the fish pull The source wheel out positive terminal 100 and one sound source output negative terminal 200 are divided into four parts (four) pulls the _hai-connecting seat; and the sound source outputs the positive/negative ruizi 100, 200 and the ϋ命 电 electrical guiding relationship, the following sound source output The positive terminal _ is the sandwiched fish contact tT conductive surface 132 and the guiding portion 311, and the output positive electrode can be electrically connected with the first conductive member 2 (4), and further with the wire magic, 32 /第-^ The sound source signal is sent to the speaker by the service level 1 :: The application state is as follows: as shown in the 8th riding, the main output is connected to the sound of the joint; 1 === The connection (10) is similarly available to the two lions; for example, the seventh _, n^=negative sir, 'one of which passes through the cap 11 and the guiding portion 311 The sound source is rotated and the positive electrode 100 is electrically connected to the second conductive member 3, forming a path with the wire 32, and a sound source is outputted. In addition, it is electrically connected to the first conductive member 2^, and further forms a path with the wire 23 to transmit the sound source signal to a speaker. Therefore, compared with the conventional connector having only one conductive member and one wire: the connector of the present invention comprises two independent conductive members and two wires, so that a speaker can be replaced only by pre-setting the two connectors of the present invention. There are a number of well-known connectors for the four. It can be seen from the first and second actual states that the user no longer needs to make a jumper, which can improve the controllability, and avoid the quality of the jumper affecting the sound quality of the speaker and the loss of the jumper. The number 4 of the connecting shoes can be greatly reduced. Although the connector structure of the present invention is mounted on a speaker as a description 'but it is not limited to a speaker, the present invention can be widely applied to audio-visual entertainment related devices [e.g., audio main unit or amplifier, etc.).
