無論是進口音響還是國產音響，在日常的使用過程當中，總會或多或少出現一些故障。那么音響設備聲音聽不清或有噪音怎么回事？
山東會議室音響廠家為您講解一番吧。
Whether it is imported or domestic audio, there will always be some failures in the daily use process. So what's wrong with the sound of the audio equipment? Shandong conference room audio manufacturer will explain it to you.
音響設備聲音聽不清
The sound of audio equipment cannot be heard clearly
1.有聲音，但是只有高音，卻沒有低音。這種故障一般是因為音響設備的音量過大，長時間使用，把平時常說的低音炮給燒了，也可能是線頭斷了。
1. There is sound, but only high pitched, but no low pitched. This kind of fault is usually caused by the excessive volume of the audio equipment, which burns the subwoofer that is often used for a long time, or the wire may be broken.
2.有聲音，但聲音不清晰，聽不清具體聲音。這種故障除了高音喇叭損壞外，還可能是信號線斷，或者是高音放大的集成塊損壞。
2. There is a sound, but the sound is not clear and the specific sound cannot be heard clearly. In addition to the damage of the tweeter, this fault may also be caused by the disconnection of the signal line or the damage of the tweeter amplifier integrated block.
音響設備出現噪音
Noise from audio equipment
1.聲音能夠正常播放，但是會不時傳出“噼哩叭啦”的噪音。有些用戶反映電腦使用耳機時沒有其他雜音，只是使用音響設備時會不定期的發出“噼哩叭啦”的噪音，有時時間長一些，優勢時間短一些。剛開始也懷疑是音頻信號插頭接觸不良，但是也重新插拔過，換過線還是沒有解決問題。解決辦法：更換新的質量優良的電源插座。
1. The sound can be played normally, but there will be "crackling" noise from time to time. Some users report that there is no other noise when the computer uses headphones, but the sound equipment will make "crackle" noise irregularly. Sometimes the time is longer, and the advantage time is shorter. At the beginning, I also suspected that the audio signal plug was in poor contact, but it was also plugged in and out again. The problem was still not solved after changing the cable. Solution: replace with a new high-quality power socket.
2.聲音能夠正常播放，但是如果調整重低音(BASS)時，喇叭里就會傳出“霹靂啪啦”的噪音，根本無法忍受。有時候一些音響設備在使用時會有“霹靂啪啦”的雜音，特別是旋轉重低音旋鈕時，情況會更加嚴重。
2. The sound can be played normally, but if the bass is adjusted, there will be "Thunderclap" noise from the speaker, which is unbearable. Sometimes some audio equipment will have "Thunderclap" noise during use, especially when rotating the subwoofer knob, the situation will be more serious.
因為是旋轉BASS按鈕引起的，可以肯定是BASS電位器損壞。大多數音響設備的音量調節和重低音調節，都使用的是電位器來改變信號的強弱，除了新出的數字調音的電位器，電位器是通過一個活動觸點改變在炭阻片上的位置來改變電阻值的大小。
Because it is caused by rotating the bass button, it is certain that the bass potentiometer is damaged. Potentiometers are used for volume adjustment and bass adjustment of most audio equipment to change the signal strength. Except for the newly developed digital tuning potentiometer, the potentiometer changes the resistance value by changing the position on the carbon resistor through a movable contact.
隨著使用時間的增長，電位器內會有灰塵活雜志落入，電位器的觸點也可能會氧化生銹，造成接觸不實，這時在調整音量時就會有“霹靂啪啦”的噪音出現。解決辦法：對于這種問題處理起來很簡單，更換一個新的電位器就可以了。
With the increase of use time, dust and live magazines will fall into the potentiometer, and the contacts of the potentiometer may also be oxidized and rusted, resulting in poor contact. At this time, there will be "Thunderclap" noise when adjusting the volume. Solution: it is very easy to deal with this problem. It is enough to replace a new potentiometer.
The reasons for the failure of audio equipment cannot be analyzed unilaterally. It is not caused by subjective reasons, but is affected by objective reasons. I hope you can understand the above http://www.zkvd.cn ！
