There is always a problem in life, that is, the speaker has a noise. This will have a great impact on whether we listen to music or watch movies. What if there is noise in the sound? How to remove the noise from the speakers?
Speaker damage
The reason why the speakers are murmurs, the root cause of a large part of the problem is the damage of the satellite speakers or the sub-box. This type of fault may be caused by the amplifier's amplifier circuit (the filter capacitor is too small or damaged to cause noise) or it may be caused by the speaker itself. For example, if the volume is too loud when listening to the song, causing the speaker unit to treble or the bass part to be broken or damaged, then there will be noise when it continues to be used.
Solution: If it is really caused by this reason, then unfortunately, we can't solve the problem fundamentally, this can only send your speakers for repair.
Audio and video file quality issues
Nowadays, online music is popular. Many songs are downloaded from the Internet. It is convenient to use it. However, it is because of this open platform that the quality of documents is also uneven. For example, some music files are not small in size when downloaded, but the quality is not so high, which will cause noise during playback. This is a problem that occurs during the file suppression process and is almost impossible to solve.
Solution: It can only improve the quality of music files, but there is no other way.
Line input is not true
Regardless of whether it is a 2.1 speaker or a 2.0 speaker, there is a connection line from the sound source to the speaker, that is, the signal line of the line input. If this signal line is not connected properly, it is likely to cause noise. For example, the general 3.5mm signal line is a two-stage plug. If it is not plugged in, it will definitely have a problem of noise or even a side channel. Of course, if the line input is not true, it will cause the chassis itself to leak into the audio line, and the noise will become more serious.
Solution: Plug in the signal line, chassis ground
Signal interference cause
If your speaker only has a noise in a special case, then you can almost determine the problem of cell phone interference: the speaker works normally most of the time, when the phone or text message is incoming, the speaker will have regular noise. , causing abnormal use. In fact, this is related to the amplifier's power amplifier. With the popularity of Class D digital power amplification, this phenomenon is expected to disappear.
Solution: Take off your phone and replace it with a digital amplifier.
Sound card driver problem
This phenomenon is very common and atypical. It only happens at special times. Anyway, I have encountered it once. The speaker has a new noise, and all the troubleshooting methods have not been improved. The fault disappears after reinstalling the sound card driver. Don't throw away your speakers when you are desperate, try changing your sound card driver.
Solution: Reinstall the sound card driver
