Audio commentary

Hello, everyone. The meeting will answer your questions. Many people still don't know how the small speaker is connected to the desktop computer and how the speaker is connected to the computer desktop. Now let's take a look at it.

Answer:

1. Use the usb interface on the loudspeaker to connect the usb interface on the host panel of the computer, and plug the loudspeaker interface into the green interface of the desktop motherboard, so that the loudspeaker of the computer can be used after it is connected. After the power is connected, you can play the song, and then you can use the computer's speakers. You can plug in the power and play the sound on the computer to try the effect.

2. Solution to loudspeaker noise:

3. Use the wire to expose the metal strip at both ends of the wire, one end is connected to the outside of the computer mainframe, the non-critical metal parts are connected, and the other end is grounded. Pay special attention to the wiring outside the mainframe of the computer, do not choose the key parts. Pay attention to safety, because it is caused by magnetic flux leakage from the power supply. You can block magnetic flux leakage by installing a shield made of iron-containing material for the transformer, or you can use an external transformer. The most fundamental thing is to choose products with large brands and solid materials. Stray electromagnetic interference is very common, computer mainframe, speaker line, frequency divider, wireless equipment may become the interference source of the speaker. When conditions permit, the main chassis should be as far away from the host computer, mobile phones and other electronic devices as far as possible.

This is the end of this article. I hope it will be helpful to all of you.
