困扰已久的问题：电脑音响滋滋响，令你烦恼不堪？别着急！php小编苹果为你带来解决妙招。下面将详细介绍电脑音响有杂音的常见原因，以及针对不同故障的一步步解决方法，让你的音响重获清澈音质，享受美妙声音的乐趣。
电脑右下角小喇叭右键-点声音-播放-扬声器右键-属性-级别-FontPinkIn右边的小喇叭点掉，问题解决，不客气~什么高频信号，干扰，静电，主板有灰，音响有问题啥的，别信都是复制?
点击左下角的开始图标，点击控制面板，点击硬件和声音，选择最下方的Realtek高清晰音频管理器。选择选项。录制设备下勾选将所有输入插孔分离为单独的输入设备即可
耳机或者音箱出现杂音，最有可能就是声卡驱动的问题，建议大家先将声卡驱动卸载（可以在驱动软件中卸载或者电脑设备管理器中卸载声卡驱动），然后再重新安装声卡驱动，安装声卡驱动可以借助驱动精灵或者驱动人生之类的软件进行自动搜索驱动安装。
音源到音箱有输入的信号线，如果这根线没有插入完整，也有可能造成音箱有杂音的问题，检查一下音源到音箱有输入的信号线和接入电脑的音频线是否有没有插入不实的情况。
1、首先确保线路，和声卡驱动是否正常在右下角的小扬声器不见了，这说明你的声卡驱动驱动坏了。
下载驱动人生2010更新一下声卡驱动，重启后看看能不能解决2、右击“我的电脑”----“属性”---“硬件”----“设备管理器”，打开“声音、视频和游戏控制器”有无问题3、打开腾讯电脑管家——电脑诊所——硬件问题——电脑没声音
造成电脑音响有杂音的有很多种可能。
1。电流不稳定 2。音响烂 3。声卡坏了。4。放音乐的时候周围有短波（如手机信号等等），有时候有幅射的时候也会这样 5。最没有可能的可能。。。。人品问题，无法解释解决方法：清理音频线接头或更换音频线
电脑音箱用了几年，不仅噪音明显，还伴有声音时大时小的情况：声音小了经常要开到更大的音量才有足够的声音，偶尔突然音量又复原了，突然变大的声音容易吓人一跳。
其实这一现象的出现，很可能不是什么大问题，只是因为音频线的接口氧化从而导致接触不良而已。要知道，当接头接触不良时，音频信号经过时会大幅度衰减，因而出现声音变小，噪音增大等问题。同时接触不良还会令音箱的输入阻抗大增，在这种情况下，音频线就成为一条收集干扰信号的天线，使得干扰信号电平剧增。再加上音箱必须加大音量才有足够的声音，这样干扰信号增加，放大的倍数也增加，双重的影响，必然导致噪音剧增。
知道原因，解决起来也就简单了，我们只要用砂纸将音频接口上的氧化层去除后，就有相当大的概率让音箱声音恢复正常。不过最好的办法是更换一条音频线，接口镀金的音频线是最好的选择，这倒不是为了提升音质，而是因为镀金能极大的增强接口处的抗氧化性能，减少接触不良带来的影响。
调节音量致噪音，电位器损坏是关键
解决办法：清洗、更换电位器或将电位器放在固定位置上
老电脑音箱在调节音量时可能会出现噪音陡然出现，或是音箱无声等一系列问题，这主要是是音箱里的音量电位器老化损坏引起的。
从原理上看，电位器是依靠弹片在碳槽上滑动，从而获得不同的电阻来控制音量。但在长期使用中，弹片的滑动会在碳槽上划出凹槽，而从凹槽脱落的碳粒子会落在滑槽上。这样在转动音量电位器时，多种异常现象会一起出现：脱落的碳粒子摩擦会产生噪音；凹槽弹片与碳槽接触不良也会产生噪音；同时凹槽碳粒子的存在，令电位器转动时的阻值易大幅波动，从而出现声音时大时小的情况。
要解决这一问题，最好的办法自然是更换音量调节的电位器，而用酒精对电位器进行清洗，也能起到不错的效果。不过普通使用者难有拆音箱并进行内部清洗的动手能力，那怎么办呢？如果音箱使用的是线控来调节音量，那么更换整条线控就可以了。如果音量旋钮做在音箱上，也没关系，我们推荐先将音量电位器固定在一个音量较大、接触较好且不易产生噪音的位置上。这时音箱音量肯定较大，我们只要去淘宝上买一个音箱线控，将调音量的任务交给线控。这下音箱又可以正常使用了。
电位器损坏的噪音，可通过固定音量，增加线控器来解决。
USB设备互相干扰也会产生噪音
解决方法：使用USB充电器为音箱供电或是将音箱与其它设备插分别拆在不同组的USB口上。
现在不少小音箱采用的都是USB供电，在使用其他USB外设时，用户经常能听到音箱里传来噪音：当读卡器一开始读写数据马上就会出现噪音，甚至还能从音箱中听到一用硬盘运行时的嗒嗒声。
如果您在使用电脑主机自带音响时遇到杂音问题，可能会影响您的使用体验，同时也会影响您对音质的要求和期望。在这篇文章中，我们将为您介绍一些解决这一问题的方法，希望能够帮助您排除电脑主机自带音响杂音的困扰。
首先，您可以检查电缆连接是否良好。松动的电缆连接可能导致杂音问题。请确保所有连接都牢固无误，尤其是音频输入和电源连接。
其次，您可以尝试调整电脑的音频设置。打开控制面板，找到音频设置选项，检查音量和均衡器设置是否正确。有时候调整这些设置可以帮助减少音响杂音。
驱动程序的问题也可能导致音响杂音。请确保您的电脑主机的音频驱动程序是最新版本，您可以去厂商官网下载最新的驱动程序进行安装。
电磁场干扰可能是导致音响杂音的一个常见原因。尽量将电脑主机远离可能产生干扰的电器设备，如微波炉、电磁炉等，看看是否能够改善音响的表现。
如果以上方法都无法解决问题，您可以考虑使用隔离设备。隔离设备可以帮助排除电流噪音和地线环路噪音，提高音频输出的清晰度。
电脑主机自带音响有杂音可能会给用户带来困扰，但通过一些简单的方法和技巧，我们可以解决这一问题，提高音质和用户体验。希望本文介绍的方法能够帮助您解决电脑主机自带音响杂音的困扰，让您享受更好的音频体验。
很多人在使用电脑音响时都会遇到杂音的问题，其原因可能有很多种。首先，检查音箱接口是否松动或接触不良；其次，信号源或音箱自身的问题也可能导致杂音；最后，电磁干扰或外部环境因素也可能是杂音的来源。
针对音箱接口松动或接触不良的问题，首先要确保连接稳固，可以尝试更换连接线。对于信号源或音箱本身的问题，可以通过更换音箱或者调整电脑声卡的设置来解决。同时，加强对电磁干扰的防护和消除外部环境因素也是重要的解决方法。

很多种情况会造成电脑音响有杂音，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。
一般来说，电脑音响多是有源音箱，其内部一定会存在放大器，所以噪音不可避免，有源音箱的噪音按来源大致可分为电磁干扰、机械噪声和热噪声等。
Electromagnetic interference can be mainly divided into power transformer interference and stray electromagnetic wave interference. Generally speaking, the interference of the power transformer is caused by the magnetic leakage of the power supply of the multimedia speaker. When conditions permit, the effect of installing a shielding cover on the transformer is very obvious, which can block the magnetic leakage to the greatest extent. The shielding cover can only be made of iron. Made of type material. We should try our best to choose products from big brands and solid materials. In addition, using an external transformer is also a good solution.
Stray electromagnetic wave interference is relatively common, and speaker wires, crossovers, wireless devices or computer hosts can all become sources of interference. Place the main speakers as far away from the computer host as possible and reduce peripheral wireless devices.
Mechanical noise is unique to active speakers. During the operation of the power transformer, the vibration of the iron core caused by the alternating magnetic field will produce mechanical noise, which is very similar to the buzzing sound emitted by the fluorescent lamp ballast. Choosing good quality products is still the best way to prevent this noise. In addition, we can add a rubber shock-absorbing layer between the transformer and the fixed plate.
Another thing that should be noted is that if the potentiometer is used for a long time, poor contact will occur between the metal brush and the diaphragm due to dust accumulation and wear, and noise will be generated during rotation. . If the screws of the speaker are not tightened and the inverter tube is not properly processed, mechanical noise will also be produced when playing large dynamic music.
This kind of thermal noise can be dealt with by replacing low-noise components or reducing the component workload. In addition, lowering the operating temperature is also one of the effective methods.
In addition, some computer speakers will produce noise when the volume is adjusted too high. This situation is caused by the fact that the output power of the power amplifier may be small and cannot avoid the large dynamic peak signal at the moment of music, or it may be caused by speaker overload distortion.
If there is noise in the computer, you can solve it as follows: 1. Make sure that the audio plug is correctly inserted into the back panel of the case (generally
Computer case
The pink round port on the back panel is the microphone. Socket; the green round port is the jack for audio, speakers and other amplifiers; the blue round port is theline input
(such as MP3) jack) and there is sound (no matter what the sound is, as long as there is sound). .2 Click the "Start" button (you can also press the Windows logo key on the keyboard) to pop up theStart menu
. Mouse click onControl Panel
. See theControl Panel
page. 3. Click "Hardware and Sound" (green text) in the pop-up "Control Panel
" page. to bring up the hardware and sound control page. 4. Click "Realtek High Definition Audio Manager" (item 6, green) in the pop-up hardware and sound control page. to pop up the Realtek High Definition Audio Manager page. 5. There is a blue "Device Advanced Settings" button in the upper right corner of the Realtek High Definition Audio Manager page. Clicking it will pop up the advanced settings page. 6. In the advanced settings page, select the radio button in front of "Separate all input jacks into separate input devices". Then press "OK" in reverse order of the pop-up of all windows. Note: There are usually two reasons that affect the sound effect: 1. Line problems. If the contact is not reliable, the mainboard leakage will cause other voltages and currents to be mixed into the circuit. The most original and effective solution is to add a capacitor to absorb interference, but it requires professionals to do it; 2. It is the interference of electric fields and magnetic fields. For example, the electric fields of microphones, mobile phones, internal combustion engines, magnets,communication base stations
, and magnetic fields generated by satellites. The most primitive and most effective way is to cover the perimeter of the speaker with a completely airtight wire mesh, allowing the self-circulating wire mesh to form anstatic shielding
cover for the speaker. This can block allelectromagnetic interference
except the speaker itself.Because mobile phones emit electromagnetic waves, they will cause some interference to the computer. The result will be noise in the speakers, especially when there is an incoming call or text message, because at this time, The transmitting power amplifier of the mobile phone will be larger than the normal standby power.
As for why some mobile phones don’t have it, this is a good question. In fact, some mobile phones will also have it. However, because these mobile phones use different networks, such as CDMA, which is relatively smaller (no matter Whether it is a mobile phone with a GSM network or a CDMA network, the noise generated will also be larger or smaller depending on the position and direction of the mobile phone relative to the computer), but one thing needs to be explained, it is not because you can't hear the noise. It means that the mobile phone you use is the best, because the same mobile phone will show different results in front of different computers. This depends on the anti-interference function of the computer used and the filter circuit of the speaker (Qualcomm , low pass), and the quality of the wire used. It is precisely because of the above reasons that some mobile phones have them, some do not, some are large, and some are small.
