Speaker current sound processing methods

Introduction: We will always encounter such a problem in life, that is, there is noise in the speakers. This will have a great impact on us listening to music or watching movies, so what should we do if there is noise in the speakers? How to clear the noise from the speakers?

Damaged speakers

Why do speakers appear? Noise, a large part of the root cause of the problem is damage to the satellite speakers or sub-speakers. This kind of fault may come from the box amplification circuit part (the filter capacitor capacity is too small or damaged, which may cause noise), or it may be caused by the speaker itself. For example, if the volume is turned up too high while listening to music, causing the treble or bass part of the speaker unit to be cracked or damaged, then there will be noise when you continue to use it.

Solution: If this is really the cause, then unfortunately, we cannot fundamentally solve the problem, so we can only send your speaker for repair.

Audio and video file quality issues

Nowadays, online music is very popular, and many songs are downloaded from the Internet. It is true that it is convenient to use; however, it is precisely because of this open platform. Therefore, the quality of the documents also varies. For example, some music files are large in size when downloaded, but the quality is not very high, which will cause noise during playback. This is a problem that occurs during the file compression process and is almost impossible to solve.

Solution: There is no other way but to improve the quality of the music files.

Incorrect line input

Whether it is a 2.1 speaker or a 2.0 speaker, there is a connecting cable from the audio source to the speaker, which is the line input signal cable. If this signal line is not connected properly, it is likely to cause noise. For example, the general 3.5mm signal cable has a two-level plug. If it is not plugged in firmly, there will definitely be noise or even one channel being silent. Of course, if the line input is incorrect, it will also cause the chassis itself to leak electricity into the audio cable, and the noise will become more serious.

Solution: Plug in a solid signal line and ground the chassis

Reasons for signal interference

If your speaker only produces noise under one special circumstance, then It can almost be determined that the problem is caused by mobile phone interference: the speaker works normally most of the time, but when a call or text message comes in, the speaker will make regular noise, causing abnormal use. In fact, this has something to do with the speaker's power amplifier. With the large-scale popularization of Class D digital power amplifiers, this phenomenon is expected to disappear.

Solution: Take away your mobile phone and replace it with a set of digital amplifier speakers.

Sound card driver problem

This phenomenon is very common and atypical. It only occurs at special times. Anyway, I encountered it once. There is a new noise coming from the speaker. I have tried all the troubleshooting methods but there is no improvement. After reinstalling the sound card driver, the problem disappears. Don't throw away your speakers when you are at your most desperate. Try changing the sound card driver.

Solution: Reinstall the sound card driver
