Today's people pursue a high-quality life and focus on enjoyment; in terms of personal development, they focus on versatility. When the audio equipment of mobile phones and computers cannot meet your needs, they generally buy speakers with high configuration. In use, pay attention to the explanation of "speaker sound knob cannot adjust the volume". There are some corresponding maintenance methods. If you are interested, you can read the text below:
What should I do if the volume of the speaker sound knob cannot be adjusted?
- No matter if the knob is turned to the minimum or maximum or any section in the middle, the sound of the speaker is the normal maximum volume.
- When the knob is turned to the minimum or maximum, the sound is slightly smaller; when the knob is turned to any section in the middle, the sound is slightly louder and the sound quality is not good.
- After eliminating the fault of the knob potentiometer, measure the resistance value of the potentiometer with a multimeter, and find that it can change with the rotation of the knob.
Maintenance method
- If the fault of the potentiometer has been ruled out, it should be a short circuit of the signal to the ground. In short, the copper foil of the ground end of the potentiometer of the power amplifier board is broken, which directly causes the signal to be short-circuited to the ground wire.
- It is necessary to detect the grounding end, and then repair the broken position, so that the sound can be restored to normal operation.
Speaker sound knob can not adjust the volume of the speaker sound knob failure:
- Computer speakers have been used for a long time, and high-sensitive components are prone to problems, especially the volume adjustment knob. Once a problem occurs, the volume of the left and right speakers will jump, and the volume will not be the same. No.
- When this problem occurs, it may be that the volume adjustment is too frequent or the speaker has been placed indoors for a long time, and the electronic components are aging or damp, which leads to sensitivity problems.
Maintenance method
The most effective way is to buy a new speaker and sell the old one; or repair the volume adjustment knob, but this problem will still occur if it is not used for a long time.
The sound knob of the speaker cannot adjust the volume. Generally, it has been adjusted too many times and it is damaged. If the problem is not serious, it can be repaired, but the use time is limited, so it is best to adjust the volume less. If the economic conditions are better, you can directly buy a new speaker and sell the previous one, so you don't have to worry about it. The specific method you choose depends on your own situation.
