Is there always a pulsing sound in the computer stereo? What s going on?

There is always a pulsing sound in the computer stereo because:

Turn up the volume of the microphone too much in the volume setting, causing an external electromagnetic pulse.

Or if the small sound is amplified and the pulse sound is heard, you can remove the v before the microphone is strengthened and turn down the volume.

Due to external signal interference, such as desk lamps, mobile phones, etc., this problem will occur when the mobile phone calls or the mobile phone receives information, and the interference source can be kept away from the audio.

If the quality of the computer audio is not good, the AC signal in the power supply cannot be removed and the AC component can be amplified and the pulse sound can be heard, in this case, the filter capacitor inside the speaker can be replaced.

Or a transformer to solve.

If the audio cable is damaged or in contact with the AC power cord, the AC signal is transmitted to the speaker, check whether the audio cable is damaged or in contact with the AC line, and replace it in time if it is damaged or broken.

The microphone can be increased in the Control Panel - Sound. There are pulses because the volume of the speaker is too loud, and there will be a pulse sound inside the speaker. Turn down the volume and you're good to go.

The noise coming from the chassis is likely to be caused by the high power and high speed of the CPU or graphics card fan As soon as the speed of the fan is high, some inferior fans (especially CPU fans) begin to rumble and become unstable, so there will be noise The solution is to make some oil for the fan from time to time, or directly change it to a new one, almost 40 60 oceans, depending on the CPU model

The microphone sound is low, probably because of the setting problem, turn the volume to the highest, set the microphone options, if it is already the highest, maybe there is a problem with the microphone, try a new one

It is estimated that it is a power supply problem of the computer, and it is recommended to change the power supply.

As soon as the computer Hengqin speaker is turned on, there is a buzzing current sound, which is a problem that many computer users have encountered. This electrical sound not only affects the auditory enjoyment, but can also cause damage to computer hardware. So, how can this kind of problem be solved?

First of all, we need to understand the cause of this current sound. Generally speaking, this current sound is caused by a grounding problem between the computer speaker and the power supply. When the grounding between the computer audio and the power supply is not well prepared, it will cause the current to flow back on the grounding line, resulting in a buzzing current sound.

So, how to solve this problem? First of all, we can try to replace the power cord and choose a better quality power cord to reduce the possibility of poor grounding. Second, try using an isolator to isolate your computer's speakers from the power supply.

This can effectively reduce the problem of poor grounding, and can protect the computer hardware and extend the service life.

In addition, you can also try to use a filter to filter the current between the computer speaker and the power supply to reduce the generation of current sound. In addition, regular cleaning of the computer speaker's connectors and plugs can also effectively reduce the possibility of poor grounding.

In short, it is a common problem that there is a buzzing current sound as soon as the computer speaker is turned on, but with some simple operations, we can effectively solve this problem, and protect the computer hardware and improve the service life.
