抗干擾磁環(huán)的作用及準(zhǔn)確使用方法

       自己在耳機(jī)線上和信號(hào)線上也加過這樣的磁環(huán)，不過效果不是的！確實(shí)加了磁環(huán)后手機(jī)的信號(hào)干擾會(huì)減弱，但不能完全濾去！可能沒象上邊這樣把線在抗干擾磁環(huán)上邊繞了一圈。這樣繞一圈的效果應(yīng)該會(huì)比直接扣上去效果好很多。 還有一點(diǎn)疑問：同一條耳機(jī)線為什么在耳放輸出的地方打手機(jī)干擾就會(huì)很明顯，但越靠耳機(jī)線后邊影響就越變小，到了耳機(jī)線的中間位置的時(shí)候就幾乎沒影響--耳機(jī)線本身并不帶屏蔽層的。從這點(diǎn)看，是不是要起好的效果應(yīng)該是在輸出端的地方就上磁環(huán)。是不是功放里邊對(duì)電磁干擾的敏感度會(huì)比線材更高點(diǎn)！

        信號(hào)線上加了磁環(huán)后頻和高頻部分會(huì)受影響，泛音變少變干！ 視頻線一般就比較多見，上不上檔次的視頻線都可以見到加磁環(huán)，抗干擾磁環(huán)在視頻線上的作用應(yīng)該比用在信號(hào)線上明顯。 磁環(huán)好應(yīng)該加在電源線部分和視頻線部分，扼流線圈：扼流線圈是一個(gè)以鐵氧體為磁芯的共模干擾抑制器件，它由兩個(gè)尺寸相同，匝數(shù)相同的線圈對(duì)稱地繞制在同一個(gè)鐵氧體環(huán)形磁芯上，形成一個(gè)四端器件，要對(duì)于共模信號(hào)呈現(xiàn)出大電感具有抑制作用，而對(duì)于差模信號(hào)呈現(xiàn)出很小的漏電感幾乎不起作用。扼流線圈使用在平衡線路中能有效地抑制共模干擾信號(hào)（如雷電干擾），而對(duì)線路正常傳輸?shù)牟钅Ｐ盘?hào)無影響。
