  1、音箱接线断或?#21046;灯?#24322;常

  音箱接线断裂后,扬声器单元没有激励电压,就会造成无声?#25910;稀7制灯?#36890;常不易断线,但可能发生引线接头脱焊、分频电容短路等?#25910;稀?br />
  2、音圈断

  可用万用表R×1档测量扬声器引出线焊片,若阻值为∞,可用小刀把音圈两端引线的封漆刮开,露出裸铜线后再测,要是仍不通,则说明音圈内部断线;若测量已通且有"喀喀"声,则表明音圈引线?#19979;罰?#21487;将线头上好焊锡,再另用?#27426;?#19982;音圈绕线相近的漆包线焊妥即可。

  3、扬声器引线断

  由于扬声器纸盆振动频?#20445;?#32534;织线易折断,有时导线已断,但棉质芯线仍保持连接。这种编织线不易购得,可用稍长的软导线代替。

  4、音圈烧毁

  用万用表R×1档测量扬声器引线,若阻?#21040;?#36817;0Ω,且无"喀喀"声,则表明音圈烧毁。更换音圈前,应先清除磁隙内杂物,再小心地将新音圈放入磁隙,扶正音圈,边试听边?#20204;?#21147;胶固定音圈的上下位置,待音圈置于较佳位置后,?#20204;?#21147;胶将音圈与纸盆的间?#30701;?#28385;至?#35805;?#24038;右后面封好防尘盖,将扬声器纸盆向上,放置一天后即可正常使用。

  以上就是小编今天介绍的相关知识了,大家看了以?#31995;?#20171;绍之后想必也有了一个大概的了解了吧,大?#20197;?#38899;响工程、设备这方面有需要的话可来电咨询哦,兆立电子是重庆专业的音响公司
