由于低音扬声器经常工作在较大输入功率状态,容易产生振断引线和烧坏音圈等故障。尤其是大口径低音扬声器,价格较高,弃之可惜。若能在业余条件下修复,则很有实用价值。本文试介绍若干行之有效的扬声器简单修复方法,供参考。一、判断扬声器故障部位首先,在静态条件下,用手轻微推动纸盆,若听到摩擦声,说明音圈已断路,可用万用表电阻档验证。扬声器的音因引线一般是粘接在纸盆上,再焊至接线片的。多数扬声器需揭开中部的电镀膜方能看到纸盆上
As the bass speakers often work in a larger input power state, prone to vibration leads and burn voice coil and other failures. Especially large caliber woofers, the higher the price, the pity to abandon. If you can repair in amateur conditions, it is very practical value. This article describes a number of proven speaker simple repair methods for reference. First, determine the speaker fault parts First of all, under static conditions, the hand slightly push the cone, if you hear the friction sound, voice coil has been open circuit, available multimeter resistance file verification. The sound of the speaker is generally glued to the cone and then to the tab. Most loudspeakers need to uncover the middle of the plating film to see the cone
