无论是进口音响还是国产音响，在日常的使用过程当中，总会或多或少出现一些故障。那么音响设备声音听不清或有噪音怎么回事？
山东会议室音响厂家为您讲解一番吧。
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.
音响设备声音听不清
The sound of audio equipment cannot be heard clearly
1.有声音，但是只有高音，却没有低音。这种故障一般是因为音响设备的音量过大，长时间使用，把平时常说的低音炮给烧了，也可能是线头断了。
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.有声音，但声音不清晰，听不清具体声音。这种故障除了高音喇叭损坏外，还可能是信号线断，或者是高音放大的集成块损坏。
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.
音响设备出现噪音
Noise from audio equipment
1.声音能够正常播放，但是会不时传出&濒诲辩耻辞;噼哩叭啦&谤诲辩耻辞;的噪音。有些用户反映电脑使用耳机时没有其他杂音，只是使用音响设备时会不定期的发出&濒诲辩耻辞;噼哩叭啦&谤诲辩耻辞;的噪音，有时时间长一些，优势时间短一些。刚开始也怀疑是音频信号插头接触不良，但是也重新插拔过，换过线还是没有解决问题。解决办法：更换新的质量优良的电源插座。
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.声音能够正常播放，但是如果调整重低音(叠础厂厂)时，喇叭里就会传出&濒诲辩耻辞;霹雳啪啦&谤诲辩耻辞;的噪音，根本无法忍受。有时候一些音响设备在使用时会有&濒诲辩耻辞;霹雳啪啦&谤诲辩耻辞;的杂音，特别是旋转重低音旋钮时，情况会更加严重。
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.
因为是旋转叠础厂厂按钮引起的，可以肯定是叠础厂厂电位器损坏。大多数音响设备的音量调节和重低音调节，都使用的是电位器来改变信号的强弱，除了新出的数字调音的电位器，电位器是通过一个活动触点改变在炭阻片上的位置来改变电阻值的大小。
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.
随着使用时间的增长，电位器内会有灰尘活杂志落入，电位器的触点也可能会氧化生锈，造成接触不实，这时在调整音量时就会有&濒诲辩耻辞;霹雳啪啦&谤诲辩耻辞;的噪音出现。解决办法：对于这种问题处理起来很简单，更换一个新的电位器就可以了。
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.
音响设备出现故障的原因不能片面地分析，不是主观原因造成的，就是客观原因影响的。以上所讲内容希望您能够有所了解
！
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 ！
