电磁干扰又主要可以分为电源变压器干扰和杂散电磁波干扰。
Electromagnetic interference and can be mainly divided into power transformer interferences and spurious interference of electromagnetic wave.
1、电源变压器干扰
1, the interference of power transformer
由于多媒体音箱的电源漏磁造成的，在条件允许的情况下为变压器加装屏蔽罩的效果非常明显，可以最大程度的将漏磁阻挡，屏蔽罩只能用铁型材料制作。我们应该尽量选择大品牌、用料扎实的产品，另外，使用外置变压器也是个不错的解决办法。
Because the magnetic leakage caused by the power of multimedia sound box, in the conditions allow for the transformer is additionally provided with a shield cover the effect is very obvious, can be the greatest degree of the magnetic flux leakage barrier shield can only be made of iron material. We should try to choose a big brand, with solid products, in addition, the use of an external transformer is also a good solution.
2、杂散电磁波干扰
2, stray electromagnetic wave interference
比较常见，音箱导线、分频器、无线设备或者电脑主机都会成为干扰源。将主音箱在允许条件下尽量远离电脑主机，并且减少周边无线设备。

More common, speaker wire, frequency divider, wireless device or the host computer will become the source of interference. The main speakers in the permit conditions as far as possible from the host computer, and reduce the surrounding wireless equipment.
