What should I do if the sound of the speaker is hoarse?

　　What should I do if the sound of the speaker is hoarse? 1. There is a problem with the sound source of the speaker (that is, the sound input), and the input sound is also hoarse. If you check this way, you can try to use good music (sound source) to see if there is a hoarse sound. 2. The quality of the speaker itself is defective, If so, take it to the repair shop to repair it. 3. The volume is not adjusted properly,

　　It may be that the microphone and the speaker are too close to each other, and the sound is self-excited, so a whining sound appears. You can turn off the volume of the microphone and try it. To the right place.

　　There may also be a problem with the quality of the speaker itself. You can try another computer and you will know which part of the problem is.

　　There are three possibilities for this situation. The first is the friction between the woofer's voice coil and the magnetic seam. The second is the aging of the power amplifier (or a certain amplifying element is damaged) and performance degradation. The third is the power of the speaker ( Or impedance) does not match the power amplifier. The solution is: [1] First check whether the impedance and power of the power amplifier and speaker match (if your speaker is not assembled by yourself but sold by the manufacturer, this step can also be omitted). [2] Try another power amplifier that is equivalent to the power of the speaker (if the power is large, please control the volume at half). At this time, if the sound quality is normal, it means that there is a problem with the original power amplifier; if the sound is still hoarse and the problem persists, it means There is a problem with the woofer of the speaker. [3] Try changing to the right speakers. After the above three steps of inspection, the problem can basically be found out.
