How to solve the noise in the loudspeaker ?
If the noise inside the loudspeaker is eliminated.
There are several reasons for noise:
First, electromagnetic interference
Second, ground wire interference
Third, mechanical noise and thermal noise
In the process of using the computer speakers with subwoofers, many users have encountered the problem of noise. When it is serious, people have the impulse to smash the speakers.
Faced with this situation, professional enthusiasts will tell you that there are many solutions: rubbing the machine, changing the capacitor, changing the circuit, upgrading the fever cable, etc.
But ordinary players do not have such professional knowledge and hands-on ability, and more than 100 yuan of computer speakers are not worth the trouble. Is there really nothing I can do in the face of computer speaker noise?
Tells you that sometimes it is not complicated to solve the problem of speaker noise as long as the right medicine is applied to the case.
Low noise: poor contact is the cause
Solution: Clean the audio cable connector or replace the audio cable
The computer speakers for desktop have been used for several years, and the noise is not only obvious, but also accompanied by loud and small sounds.
When the sound is low, it is often necessary to turn it to a higher volume to have enough sound, and occasionally the volume suddenly recovers, and the suddenly loud sound is easy to frighten people.
In fact, the appearance of this phenomenon is probably not a major problem, but the poor contact caused by the oxidation of the interface of the audio cable.
You should know that when the connector is in poor contact, the audio signal will be greatly attenuated when passing, so the sound will become smaller and the noise will increase.
At the same time, poor contact will greatly increase the input impedance of the computer audio speakers. In this case, the audio line will become an antenna for collecting interference signals, which will dramatically increase the interference signal level.
In addition, the sound box must increase the volume to have enough sound. In this way, when the interference signal increases, the amplification factor also increases. The double impact will inevitably lead to a sharp increase in noise.
It is easy to solve the problem if we know the reason. As long as we remove the oxide layer on the audio interface with sandpaper, there is a considerable probability that the sound of the speaker will return to normal.
However, after the original coating on the surface of the audio cable is damaged, it is easy to produce secondary oxidation, allowing the fault to reappear.
Therefore, the best way is to replace an audio cable. The gold plated audio cable at the interface is the best choice. This is not to improve the sound quality, but because gold plating can greatly enhance the oxidation resistance at the interface and reduce the impact of poor contact.
The gold plated audio cable of the interface has stronger oxidation resistance, which can greatly reduce bad contact.
