Is my computer s front panel speaker noisy?

The front panel of your computer is noisy, you can check the Qingxiang Tea panel error, whether the data cable connection is not plugged in properly, adjust it.

Place your audio signal cable reasonably, don't get entangled with any cables, and clean up your audio jack.

If the front panel speaker of your computer is noisy, it may be caused by poor contact, you can take a look at whether the connection between the panel and the motherboard is loose or not.

It should be that the noise is a bit dirty, so you can eliminate the noise first.

Is my computer's front panel speaker noisy? This is estimated to be due to the improper equipment of some parts of your computer during the assembly process, which will cause some noise, and it is recommended to ask some professionals to help.

If the noise is relatively loud,Then in front of the computer,It should be possible to plug in the speaker,And then it can be fully recovered。

If this happens, it may be suitable for this speaker to be broken, so it will cause a big one, in this case, it is recommended to replace the speaker.

The front panel of my computer is poor and the sound is noisy, so you can re-debug it if you don't debug it.

The reason for this situation may be the reason for the hardware mismatch, and normally I suggest that you replace the hardware again.

The front panel of my computer is too noisy, and this one looks like it's too much garbage, too much dust.

In front of your computer. Half-plugged speaker noise, but this is presumably from the horns. It should be that the horn is blocked, which is a bit of a problem.

If your computer is repaired first, then it will be repaired relatively large. Put me one of its possibilities is not impressed by the reason who said not to be more high.

The reason why the computer speaker is very noisy when plugged in.

1. If you turn on the switch of other electrical appliances, the speaker will respond. It shows that the sensitivity of your speaker is quite high,You might as well replace its audio cable with a shielded audio cable The cost is about 10 yuan,It is best to cover the power amplifier part (preamp) in the machine with a metal cover,The metal cover is grounded or grounded。

2. When the speaker is turned on, there is a popping sound. The solution is to replace the switch with a bootstrap switch circuit, or turn on the speaker to minimize the sound first.

3. If there is a buzzing sound. That's when the capacitor used to remove the AC component from your power supply rectification part is broken, or the inductor coil is short-circuited. Generally, the first capacitor of the rectified part is connected in parallel at both ends of the positive and negative poles, and you can buy another one and replace it according to the above identification (the positive and negative poles of the capacitor should not be reversed).

Another possibility is that the audio line of your signal source is not shielded, causing the electromagnetic waves in the space to interfere with the signal source, and the amplifier amplifies this part of the clutter to amplify the humming sound that appears. Replace it with shielded wire with the first one.

If the problem can't be solved on its own, the best thing to do is:

1. Buy a shielded signal cable.

2. Buy a set of power supply with rectifier and replace it directly.

1. Generally speaking, computer audio is mostly active speakers, and there will be amplifiers inside, so noise is inevitable, and the noise of active speakers can be roughly divided into electromagnetic interference, mechanical noise and thermal noise.

2. Electromagnetic interference can be mainly divided into power transformer interference and stray electromagnetic wave interference.

3. Generally speaking, the power transformer interference is caused by the power leakage of the multi-speaker power supply, and the effect of installing a shielding cover for the transformer is very obvious when conditions permit, which can block the magnetic flux leakage to the greatest extent, and the shielding cover can only be made of iron materials.

The problem should be with the acoustics. The excessive sound of the audio current is generally caused by the mismatch of the transformer power or the loosening of the winding coil of the transformer copper wire. Nowadays, many transformers do not use copper wires at all, but aluminum enameled wires, and noise is one of the biggest problems.

If you prefer to do it manually, it is recommended to turn on the stereo to see if the transformer is small or of poor quality, and if so, then go to the thrift market to find a transformer and replace it. Of course, this requires knowledge of the basic principles of electrical appliances.

That can be a bit of a problem with the interface cable of the speaker! You try not to plug it all!! If you can, change it, it's not expensive!!

This is 100% a problem with the audio! This belongs to the hardware problem of the audio,Go back to replace or repair your audio,It's definitely a product problem!

That's a small thing caused by voltage instability.

"The computer has sound" means that there is no problem with the computer's settings, check whether the connection cable of the speaker is good, whether the connected interface is correct, if these are not problematic, it may be that the speaker is faulty.

Why does a computer make noise and what causes it? Teach you a trick to solve the computer noise problem.

First of all, it is necessary to determine the noise**, the way is to unplug the audio input line to see if there is still noise, if there is a sound itself is not of good quality, repair or replacement; If there is no noise after unplugging, then change the audio cable to see, after replacing it has not improved, it is a problem with the computer's audio output, then you can only repair or replace the motherboard.
