The computer is noisy when the speaker is plugged in, and the computer speaker is very noisy when it

There are several possibilities.

1.Maybe you have a bad contact with the speaker slot, you check it out.

2.Maybe the volume adjustment is not adjusted well, you go and see, maybe you set the off-site environment, turn off the speaker (to the sound and audio equipment to adjust).

3.You go to the BIOS under the external device adjustment and see if it is set up.

If you don't understand, you can send me a consultation. I'd be happy to solve such a problem with you!!

It means that your computer is not how, no way, your computer is too poor in all aspects, including the power supply, unless you change the computer.

Poor quality speakers tend to be noisy. This noise is a continuous buzzing ring. It is most noticeable at night. If there is occasional noise, it is recommended to change the sound card driver, if it does not work, it means that there is a problem with the sound card. Or try changing the stereo!

Do you really know how to turn off the stereo?

When shutting down, the first thing to do is to turn off the power amplifier. In this way, when the power supply of other equipment (such as audio source equipment) is cut off, the impulse signal such as the reverse peak voltage will not act on the power amplifier. Otherwise, it will cause strange noises and damage to the amplifier.

Before switching on and off the audio power supply, turn the volume of the power amplifier to the minimum, so that the power amplification of the power amplifier is almost zero, at least in the case of misoperation, it will not harm the speaker. This is the most effective means of protection.

In addition,"Turn off the machine and rewire", do not turn on the amplifier to connect the speaker, in case the two wires of the speaker contact and short circuit, burning the amplifier.

Why do speakers sometimes make noise?

If it is a Yalanshi speaker, it has the characteristics of low noise. The noise floor of some audio sources (VCD, *** PC, sound card, etc.) is far higher than that of the speaker amplifier. When noise occurs, unplug the audio input cable of the audio input port of the speaker.

Hope it helps you out! Good luck!

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.

Summary. Desktop computers don't have their own speakers, so you have to use external speakers or headphones to hear the sound.

Desktop computers don't have their own speakers, so you have to use external speakers or headphones to hear the sound.

A computer is composed of a hardware system and a software manuscript vibrillation system, and the software code system includes: operating system, application software, etc. The management software of the computer industry in the application software, the necessary weapon for the development of the IT computer industry, and the ERP software of the computer industry.

Hardware system includes: round or chassis (power supply, hard disk, memory, motherboard, CPU ** processor, orange group Wu optical drive, or sound card, network card, graphics card), monitor, keyboard, mouse, etc. (can also be equipped with headphones, speakers, printers, video screens, etc.). The motherboard of home computers generally has an onboard sound card and a network card.

Some motherboards are equipped with integrated graphics.

In addition, users can also plug in headphones on the host computer to accompany the sound of the computer. It is noted that there is a simple speaker in the desktop computer, but it is only a self-test alarm, not an audio speaker.

At present, there are a small number of desktop computers with audio equipment, but the vast majority of desktop computers do not have audio equipment in their cases, so they must be plugged into headphones or connected to this closed speaker Senna before the computer can have sound. ‍

The low sound of computer audio may have the following reasons:

Wiring problems: Check whether the cable between the speaker and the computer is firmly plugged in, there may be loose or poor contact. Try plugging the cable back in and making sure it's securely attached.

Audio device setup issues: Open the audio settings of your computer's operating system and confirm that the audio output device is correctly selected as the speaker you are using on your computer. If you select the wrong audio output device, the sound will be output to the other device.

Audio driver issues: Updating or reinstalling audio drivers may help resolve the issue. You can go to the official latest version of the driver from your PC manufacturer or audio device manufacturer and follow the instructions to install it.

Problems with the speaker itself: If none of the above methods solve the problem, it may be that the speaker itself is malfunctioning. You can try connecting your speaker to another device, such as a phone or tablet, to see if you still have the same problem.

If the problem persists, you may need to contact after-sales service or have it repaired.
