很多小白最怕的就是自己的设备出问题,常常一些小问题都会让他们手足无措。要告别这种局面最好的方法自然是不断学习,扩展自己的知识面,多涉猎一些简单的设备故障维修技术。这里装机吧www.125315.com小编就给大家分享一篇关于解决电脑音箱常见几种故障的办法。
1.电脑音箱可以正常播放,但是播放时却伴有杂音。
耳机播放时没有杂音,但接电脑音箱时可以播放声音,却伴随着“噼哩叭啦”的噪音,持续一阵后(时短时长),又恢复正常,更换连接线仍然不能解决问题。既然不是线路问题。我们就应该怀疑是不是插座问题。由于一些插座质量比较劣质,内部使用的磷铜片用久后弹性变差,导致接触不良,致使音箱电源一会儿通一会儿断,而在通断的瞬间,会产生电流放大的噪音。
解决办法
更换质量好的插座。
2. 电脑音箱可以正常播放,但一个喇叭声音大,一个喇叭声音小。
电脑音箱可以正常播放,但一个喇叭声音大,一个喇叭声音小。且如果用手掰音量电位器,就能使声道一样大音量就一样大。
这种故障一般来说都是由电位器引起的,因为音量的左右声道是独立的,里面的弹簧片用久了,弹性变弱,不能与碳阻紧密连接导致左右喇叭声音不一样
解决办法
尝试将电位器的共地端联通,看能否排除故障。
3. 电脑音箱可以正常播放,调重低音时,喇叭会有杂音。
音箱使用时传出杂音,调整重低音旋钮时,问题加剧。大部分音箱都是使用电位器来改变信号强弱从而控制音量大小和重低音程度。而电位器使用时间长了,会罗有杂质灰尘,导致其氧化生锈,从而解除不牢固,致使调音时会发出杂音。
解决办法:
对于这种现象,处理起来很简单,打开机箱,打开电位器后面的四个压接片,用无水酒精清洗碳最下电位器的活动触点阻片,并滴油润滑(或者装入新的电位器)即可解决问题。
4.电脑音箱智能播放高音。
着种情况比较常见,通常为低音炮烧坏或者线头熔断。如果是线头断了,可以自己换个新的。
5.电脑音箱有声音,但不清晰。
电脑音箱有声音,但不清晰。这类故障产生的原因主要有三种:1、信号线断了;2、高音喇叭损坏;3、放大高音的集成块损坏。
解决办法:
以上几种故障都属于较为严重的故障,送修处理。
注意:如果你使用的是软声卡,很容易无意改变设置,而导致声音不清。因此我们只需重新调整设置即可。
6.电脑音箱一开机就就“嗡嗡”作响,调节音量也无法消除,或该开电脑时播放正常,但使用一定时间后“嗡嗡”作响
这两种情况多由于电脑音箱散热不良造成的。实际上,正品的电脑音箱都带有温度 保护功能,过热时会自动停止输出,回温后又会自动恢复工作。但对于一些小厂家生产的音箱,就会节省这些成本。因此建议大家购买大厂家的电脑音箱。
