How to connect an old speaker to a computer and play music on the computer?

Look at the picture. There are only two spokesmen. Your speaker is a five-channel speaker, and the active subwoofer can form a complete 5. 1 home theater. Two speakers are connected to the "left channel" and "right channel" on the back of the speakers. Pay attention to the positive and negative poles. I didn't see the speaker cable when I looked at the picture. If I can't find it, I need to buy it. The length is ...-buy a two-part cable (you will bring it when you buy a computer speaker), that is, "one" is two green plugs, which are inserted into the sound card output end of the computer (usually green), and "two" is a red and white cable, which is inserted into the second pair of jacks on the left side of the third picture of Nendi and then inserted between the speakers. -1: Buy a small plug (3.5MM), an audio cable with a shower at one end, a computer audio output hole at the 3.5MM end, a VCD end of a speaker with a red-to-red and white conversation ...-You buy a plug with headphones on one side, usually the plug shown in the above picture. One end is plugged into the computer and the other end is plugged into the speaker. Enter and select your VCD first, and then connect the speakers. That is, the four terminals of the left channel and the right channel-the computer needs a 3.5-turn double RCA speaker to connect the speaker, and the speaker needs two bare gold and silver wires. These wires can be bought in Taobao. Actually, it's not difficult. You may need an adapter, because computer integration or built-in sound cards are generally 3.5mm interfaces. Just buy an adapter and plug it into the computer, and then connect the speaker with the speaker at the other end. Try the wire several times.
