音響設備近來突然出現了噪音，就是電流聲，不開任何音樂都有，音量越大雜音也大，以前一直好好的，突然就這樣了，是音響壞了嗎？有什么問題導致音響出現雜音呢？下面
山東音響廠家為您分析。
Recently, the sound equipment has suddenly made noise, that is, the current sound. It can be heard without any music. The louder the volume, the louder the noise is. It has been good before. Suddenly, it is like this. Is the sound broken? What is the problem that causes the audio noise? Next, Shandong professional audio manufacturers will analyze for you.
插卡不正
Incorrect card insertion
聲卡沒有同主板擴展槽嚴密分離，經過目視可見聲卡上“金手指”與擴展槽簧片有錯位現象。這種現象在ISA卡或PCI卡上都有，屬于常見毛病，想方法讓聲卡插正就能夠處理問題了。
The sound card is not closely separated from the expansion slot of the motherboard. Through visual inspection, it can be seen that the "golden finger" on the sound card is misaligned with the expansion slot reed. This phenomenon occurs on both the ISA card and the PCI card. It is a common problem. You can solve the problem by plugging the sound card correctly.
有源音箱輸入端接在了聲卡的Speaker輸出端有源音箱應接在聲卡的Line-Out端，它輸出的信號沒有經過聲卡上的放大，噪聲要小得多。有的聲卡只要一個輸出端，是Line-Out還是Speaker要靠卡上的跳線決議，默許方式常常是Speaker，所以假如需求的話，還得拔下聲卡調整跳線。
The input end of the active speaker is connected to the speaker output end of the sound card. The active speaker should be connected to the Line-Out end of the sound card. Its output signal is not amplified by the sound card, and the noise is much smaller. Some sound cards only have one output terminal. Whether it is Line-Out or Speaker depends on the jumper on the card. The default mode is usually Speaker. Therefore, if necessary, you have to unplug the sound card to adjust the jumper.
聲卡驅動程序問題
Sound card driver problem
你可能用的是系統自帶的驅動程序，或驅動有問題，假如是這樣，可以換一個聲卡驅動程序。
You may use the driver that comes with the system, or there is a problem with the driver. If so, you can change a sound card driver.
問：怎么才能這些電流聲？
Q: How can we eliminate these current noises?
答：建議使用排除法：
A: It is recommended to use exclusion method:
先把電腦音頻接入低音炮上的左右聲道（紅、白蓮花插頭）互相換著插一下，再聽聽原來那只音箱還有沒有噪音。
First connect the computer audio to the left and right channels (red and white lotus plugs) on the subwoofer and plug them in each other, and then listen to the original speaker for any noise.
如果沒有噪音而另一只音箱有噪音，那就說明這條音頻線有問題。解決方法：更換電腦對低音炮的音頻連接線。
If there is no noise and the other speaker is noisy, it means there is a problem with this audio cable. Solution: Replace the audio cable between the computer and the subwoofer.
如果仍然有噪音，那就說明不是音頻連接線的問題。請繼續往下看。
If there is still noise, it means it is not the problem of the audio cable. Please continue to look down.
把低音炮連接兩個小音箱的連接線互換一下，再聽一下原來那只音箱還有沒有噪音。
Swap the connecting wires between the subwoofer and the two small speakers, and then listen to the original speaker for any noise.
如果沒有噪音而另一只音箱有噪音，那就說明你的低音炮內部電路或者線路有問題，建議找人打開低音炮，檢查內部線路、電路有沒有虛焊，電容或某個零件是否已損壞。
If there is no noise and the other speaker has noise, it means that there is a problem in the internal circuit or circuit of your subwoofer. It is recommended to find someone to open the subwoofer and check whether there is faulty soldering in the internal circuit or circuit, and whether the capacitor or a part is damaged.
如果仍然有噪音，那就說明是音箱連接線有問題，或者是這個小音箱本身有問題。
If there is still noise, it means that there is a problem with the speaker cable or the small speaker itself.
很多種情況會造成音響有雜音，比如音箱受到干擾、接口或者連接線接觸不良、音響本身質量較差等等，以上所講內容希望能夠給您好的幫助，更多事項就來我們網站
