Description of the new type: [Technical field to which the new type belongs] This creation relates to a type of 5.1-channel headphone jack (Phone Jacks), especially a multi-channel headphone plug (ph〇ne plugs) designed structure. [Prior art] Press, the so-called Phone Plugs refer to the cylindrical terminals (10) as shown in the first figure, which are used to insert a phone jacks (Phone Jacks) that output analog audio ( 20), electrically connected with the guides (21) and (22) in it, as shown in the second picture, and then transmit the audio to the terminal through the audio cable (14), such as commercially available headphones Type person. Therefore, the handset plug (10) has the convenience of operation and use in connecting audio. However, the currently available handset plug (10) has only a few electrodes, so at most two audio signals can be transmitted, namely the left channel (11), the right channel (12) and the ground electrode (13). The stereo sound effect (STEREO); therefore, the current audio headphones can only hear two-channel sound. With the advancement of digital technology, digital audio and video are becoming increasingly popular. For example, DVD video players or surround amplifiers are basically equipped with decoding functions such as Dolby Digital or DTS, which can decode digital signals and output analog signals. The sound of La Pi Ba is based on the audio analog output terminal of 5.1 Player Audio Out on the DVD Player or surround amplifier back panel, so that "TV + DVD video player + surround amplifier + 5. 1 channel speaker To build a basic audiovisual environment for a home cinema. However, the previously revealed multi-channel sound effects must use a number of output terminals and M270546 sounder wires in order to be separately connected to the front, center, center, or surround channels. Bass La. Eight connections cause the DVD Player or surround amplifier backplane to broadcast more than 6 plugs and audio cables at AUDIO OUT, so that audio can be transmitted to each speaker to expand sound, resulting in complicated wiring on the backplane and often entangled in _ This causes a lot of inconvenience. In addition, although the 5.1 or multi-channel output allows listeners to enjoy excellent sound quality, if there are other people in the audiovisual environment who are working or not listening to music, they will Noisy to others. In addition, if you wear headphones alone to listen to multi-channel surround sound effects, it is a pity that you cannot receive multi-channel audio sources because the earphone plug (10) of the headphones only has the stereo sound function of left and ^ one channel. In response to this problem, the inventors previously disclosed the multi-channel handset plug #structure (Multichannel phone plug) disclosed in Taiwan Patent No. 217782 and US Patent No. 6,394,852, and then disclosed a single independent handset plug (30) that can pass five Or six sound signals, as shown in the fourth figure φ Μ τ / η · No; the multi-channel earphone plug (30) is composed of an arc head (31), a first sleeve (32), and a first sleeve ( 33), the third casing (34), the fourth casing (35), and the fifth casing (36) Z. The ground electrode collar (37) is put through the casing one by one to form a whole, which can transmit the function of 5 mil. Handset plug (30). Since it has approved patents in many countries and has eight patents that are not the subject of this original patent creation, its detailed characteristics are not to be praised. Naturally, the front-receiving earphone plug (30) can transmit 5.1-channel signals. It means that if there is a good phone jack (Phone Jack) to cooperate with it, the passing fruit will be reduced. For example, with the earphone socket (20) shown in the second figure, there are only two guides (21) and (22) of length B, so it cannot be used for the 5.1-channel earphone plug (30). If the number of the guides is relatively increased in the earphone socket (20) according to the multi-channel of the 5.1-channel earphone plug (30), the configuration of the multi-leads in the entire socket is involved, as shown in the second figure Conventional method, used to install 6 or 7 guides of different lengths in a listening jack (20), not only processing complex jzheng, but also need to install additional fixed or positioning elements, and its space configuration There are also difficulties. · Improper installation will affect the 5.1-channel sound transmission. Therefore, for the conventional earphone socket that cannot be applied to the latest 51-channel earphone plug, providing a solution is the main subject of this creation. [New content] The main purpose of this creation is to provide a 51-channel earphone socket. The socket body has a plurality of hollow slots arranged in the socket body, which can be used to set most of the guides in a crossover manner because of the shape of each guide. Similarly, it has the advantages of convenient manufacturing and assembly. Another purpose of this creation is that the guide is a clip-type elastic body. The elastic end of the transverse part is accommodated in the hollow slot and penetrates into the axial socket of the socket, and the straight fixed end is inserted. The slot is fixed on one side of the socket body, so that each guide piece can be assembled without the need for other fixing elements after being placed in the insulated socket body. The shape of each guide piece is the same, and it contacts the elastic end of the earphone plug. The electrical connection is stable and can obtain better 51-channel audio transmission. Another purpose of this creation is to provide a plurality of terminals on the socket body with respect to each of the guides. The terminals and the guides are connected in the form of overlap when the earphone plug is not inserted into the earphone socket. , So that the audio signal can be transmitted to other speakers through each terminal ^ 8. When the handset plug is inserted into the handset socket, the corresponding terminal is separated from the guide, and only one ground terminal is in contact with the M270546 handset plug, so that the audio signal input by the guide is received by the handset plug. Another purpose of this creation is that when a 5.1 channel receiver plug is inserted into the socket, the signal is reported to the audio controller through a detection guide provided on the socket body to output a 5 The 1-channel message is automatically adjusted, and the earphone connected to the other end of the earphone plug is provided with a more appropriate volume and sound effect. With the help of the above-mentioned technical means, this creation can provide a 5 · 1 channel plug, a stable and excellent sound delivery socket, and because the overall structure is properly configured and the volume is appropriate, in addition to being assembled on the sound, it can also be made into a connection socket or The shape of the adapter socket is used as an extension connection element for the 5.1 channel plug. [Embodiment] First, please refer to the third and fourth figures. The preferred embodiment of the present invention includes: a socket body (40), which is provided with a jack (41) in the axial direction. The depth is matched with the length of an earphone plug (30), and the upper section of the socket body (40) forms a plurality of aligned hollow grooves (42), and one side of which is provided with a first side relative to each hollow groove (42) The card slot group (43), as shown in the third figure; at least six guides (50), which are bent into a clip-shaped body, include an elastic contact portion (51) and a fixed portion (52) , Wherein the fixing portion (52) is embedded in the first side card slot group (43), and the elastic contact portion (51) is received in the hollow slot (42) and crosses the axial insertion hole (41) The upper end; a ground terminal (60), which is nested at the front edge of the socket body (40), and includes an elastic contact portion (61), which is provided at the front edge portion (411) of the socket body (40) and is exposed A side edge of the axial insertion hole (41) and a fixing portion (62) are nested in the groove (44) of the M270546 socket body (40); and an end cover (70) is provided in the cover. Insert The front edge portion (411) of the seat body (40). With the help of the upper opening, the guide pieces (50) can be automatically implanted into each predetermined first side slot group (43), fixed to the socket body (40), and the elastic contact portion (51) As shown in the eighth figure, it is accommodated in the hollow slot (42) and crosses the upper end of the axial insertion hole (41). Therefore, it is very convenient to assemble, no other fixing components are needed, and the shape of the elastic contact portion (51) of each guide (50) is equivalent to the position of the axial jack (41), so when the earphone plug (30 ) When the completed handset socket (90A) is inserted as shown in the fifth figure, the contact between each guide piece (50) and the handset plug (30) will present an average and stable electrical connection. Please return to the third and fourth figures. Another feature of this creation is the design of the clip guide (50), which allows the elastic contact portion (51) to cross the axial insertion hole ( 41), the tail end is positioned above a set of corresponding output terminal pieces (80), each terminal piece (80) is an inverted L variant, and the horizontal part is the contact end (81), The upright part is a fixed end (82) which is nested in the second side card slot group (45) of the corresponding side of the first side card slot group (43) of the socket body (40). As shown in FIG. 8, when the elastic contact portion (51) of each guide piece (50) is pressed into the terminal piece (8) by its elastic force when the earphone plug (30) is not inserted into the axial jack (41). 〇) The horizontal contact part (81) is in a continuity state, that is, after the multi-channel audio signal is input by each guide (50), it is directly output through each terminal (80) and transmitted to other Yang Sound 攻 attack (not shown). Next, as shown in FIG. 7 and FIG. 9, when the earphone plug (30) is inserted into the axial jack (41), the elastic contact portions (51) of each guide piece (50) are raised, and the corresponding Lapping on the arc head (31), the first casing (32), the second casing (33), the third casing (34), the fourth casing (35), and the fifth casing (36) At this time, as shown in the ninth figure of M270546, each guide piece (50) is separated from the terminal piece (80), and only the ground terminal (60) is in contact with the handset plug (30). And as shown in FIG. 7 and FIG. 10, the contact part (61) of the ground terminal (60) is in contact with the ground electrode ferrule (37) of the earphone plug (30), so each guide of the entire input audio signal The film (50) and the ground terminal (60) are multi-pole electrical connections, so that the 5.1-channel signal can be smoothly connected through the handset plug (30) to a multi-channel earphone (not shown). Because the guides (50) of this creation are arranged on the hollow slot (42) of the socket in a crossover manner, and form vertical contact patterns with the electrodes on the earphone plug (30); The support guide (50) has a small space and is firmly arranged in the socket body (40). Therefore, a detection guide (50A) and its corresponding terminal piece (80A) can be further embedded at the rear end of the socket body (40). As shown in the sixth and seventh figures, the detection The test guide (50A) is equivalent to the shape of each of the aforementioned guides (50). The purpose is that the detection guide (50A) will lift when the earphone plug (30) is fully inserted into the axial jack (41) to conduct. At the same time, the corresponding terminal piece (80A) is in an open state without contact. At this time, the audio controller (not shown) connected to the detection guide (50A) and the corresponding terminal piece (80A) receives the handset. After the signal of the plug (30) is inserted, the output signal can be automatically adjusted, such as: the volume is reduced to prevent the sound from being too loud and uncomfortable when using headphones. As for the controller of this speaker is not the subject of this creative patent, it will not be repeated here. What is emphasized here is that with the structural design of this creation, the 5.1-channel handset plug (30) can provide corresponding contact signals from the 5.1-channel handset socket (90A), and the volume is not large, and detection can be added. Guide (50A), achieve multiple functions in one. In addition, as shown in the eighth and ninth figures, each of the previously exposed guide pieces (50) includes a detection guide piece (50A), the ground terminal (60) and each terminal piece (80) include the corresponding terminal piece (80A). The bottom end can protrude from the socket body (40) —a small extension -10- M270546 (521), (621), and (821). With this extension (521), (621), (821), The whole socket is directly connected with the circuit board (not shown) inside the audio, or it is convenient to weld with each signal wire (not shown), which makes it more convenient when the group is shaken. And, because the volume of this creation is not large, in addition to the above-mentioned type made into an earphone socket (90A), it is installed on the back of the audio as the output of the 5 ·] [channel, which can also be shown in Figure 11 , The socket body is covered with an insulating plate (91) to form another type of connection or conversion earphone socket (90B) for 5.1-channel extension connection or conversion. The structure of the guide piece and the hollow groove is the same as that described above, but the shape is slightly modified, which will not be described in detail. Therefore, this creation is aimed at the patented 51-channel handset plug (30), and further provides a 51-channel handset socket (90A) or (90B) that can be matched with it, making multi-channel headphones only With an earphone socket (40) and an earphone plug (30), it is not necessary to use multiple output sockets or plugs to reproduce the audible 5.1-channel sound effect, which is indeed convenient and practical. As mentioned above, the structure revealed in this creation is unprecedented, and it can indeed achieve the expected effect, and it can be used by the industry, which fully meets the requirements for new patents. I ask your reviewers to approve patents to encourage Innovation, no sense of virtue. However, the figures and descriptions disclosed above are only the preferred embodiments of this creation.
