Generally speaking, computer stereos are mostly active speakers, and there must be a power amplifier inside, so noise is inevitable. The noise of active speakers can be roughly divided into electromagnetic interference, mechanical noise and thermal noise according to their sources.

Electromagnetic interference is mainly divided into power transformer interference and stray electromagnetic interference. Generally speaking, the interference of power transformer is caused by the leakage of multimedia speakers. If there are conditions, the effect of installing a shielding cover on the transformer is very obvious, which can block the magnetic leakage to the greatest extent. The shield can only be made of iron-based materials. Try to choose products with big brands and solid materials. In addition, using an external transformer is also a good solution.

Stray electromagnetic interference is very common, and speaker cables, frequency dividers, wireless devices or computer hosts will all become interference sources. The main speaker should be as far away from the computer host as possible to reduce the surrounding wireless devices.

Generally, this situation has something to do with the sound quality. Therefore, you must do your homework, listen to other people's suggestions, or audition directly before choosing the sound. I can give you some good suggestions for your reference. Dana and Mai Bo can talk. If we only pursue high notes, Dana's voice meets the requirements, but it is only fair to observe that the sound film material used by the high-pitched unit is also aluminum film. Some people in Mai Bo use power.
