山东音响厂家为您分析。
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
声卡没有同主板扩展槽严密分离，经过目视可见声卡上&濒诲辩耻辞;金手指&谤诲辩耻辞;与扩展槽簧片有错位现象。这种现象在滨厂础卡或笔颁滨卡上都有，属于常见毛病，想方法让声卡插正就能够处理问题了。
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.
有源音箱输入端接在了声卡的厂辫别补办别谤输出端有源音箱应接在声卡的尝颈苍别-翱耻迟端，它输出的信号没有经过声卡上的放大，噪声要小得多。有的声卡只要一个输出端，是尝颈苍别-翱耻迟还是厂辫别补办别谤要靠卡上的跳线决议，默许方式常常是厂辫别补办别谤，所以假如需求的话，还得拔下声卡调整跳线。
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.
声卡驱动程序问题
Sound card driver problem
你可能用的是系统自带的驱动程序，或驱动有问题，假如是这样，可以换一个声卡驱动程序。
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.
问：怎么才能这些电流声？
Q: How can we eliminate these current noises?
答：建议使用排除法：
A: It is recommended to use exclusion method:
先把电脑音频接入低音炮上的左右声道（红、白莲花插头）互相换着插一下，再听听原来那只音箱还有没有噪音。
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.
如果没有噪音而另一只音箱有噪音，那就说明这条音频线有问题。解决方法：更换电脑对低音炮的音频连接线。
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，那就说明不是音频连接线的问题。请继续往下看。
If there is still noise, it means it is not the problem of the audio cable. Please continue to look down.
把低音炮连接两个小音箱的连接线互换一下，再听一下原来那只音箱还有没有噪音。
Swap the connecting wires between the subwoofer and the two small speakers, and then listen to the original speaker for any noise.
如果没有噪音而另一只音箱有噪音，那就说明你的低音炮内部电路或者线路有问题，建议找人打开低音炮，检查内部线路、电路有没有虚焊，电容或某个零件是否已损坏。
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，那就说明是音箱连接线有问题，或者是这个小音箱本身有问题。
If there is still noise, it means that there is a problem with the speaker cable or the small speaker itself.
很多种情况会造成音响有杂音，比如音箱受到干扰、接口或者连接线接触不良、音响本身质量较差等等，以上所讲内容希望能够给您好的帮助，更多事项就来我们网站
