一套的音响设备，是需要多种设备，一起组合在一起，常用的产物分别是扬声器、分频器、箱体、吸声材料等，这么多的组合设备，交叉的地方比较多，因此音响出现故障的几率是比较高，那么大家知道音响设备出现故障后该怎么解决吗?对此了解多少呢?接下来我们一起来看看吧!
A set of professional audio equipment needs a variety of equipment to be combined together. The common products are loudspeakers, frequency divider, cabinet, sound-absorbing materials, etc. there are many places where so many combined equipment intersect, so the probability of audio failure is relatively high. Do you know how to solve the problem after the failure of professional audio equipment? How much do you know about this? Next, let's have a look!
一、无声
1、 Silent
1、音频线路断开或分频器异常。音频线路断开后，扬声器单元没有励磁电压，这将导致无声故障。分压器一般不易断开，但引线接头可能脱焊，分压器电容可能短路。
1. The audio line is disconnected or the frequency divider is abnormal. After the audio line is disconnected, there is no excitation voltage in the loudspeaker unit, which will lead to a silent fault. Generally, the voltage divider is not easy to be disconnected, but the lead connector may be desoldered, and the capacitor of the voltage divider may be short circuited.
2、音圈坏了。用万用表搁&迟颈尘别蝉;1测量扬声器引线的焊盘。如果电阻为&颈苍蹿颈苍;，用小刀刮掉音圈两端引线的密封漆，露出裸铜线，然后重新测量。如果仍然不工作，则表示音圈内部导线断开;如果测量打开并有&濒诲辩耻辞;咔嗒&谤诲辩耻辞;声，则表示音圈导线开路。焊接线头，然后将其与靠近音圈绕组的另一段漆包线焊接。
2. The voice coil is broken. Use multimeter R × 1 measure the pad of loudspeaker lead. If the resistance is ∞, scrape off the sealing paint of the leads at both ends of the voice coil with a knife to expose the bare copper wire, and then re measure. If it still does not work, it means that the wire inside the voice coil is disconnected; If the measurement is on and there is a "click" sound, the voice coil wire is open. Weld the wire end, and then weld it to another section of enameled wire near the voice coil winding.
3、音响设备扬声器导线断了。由于音箱纸盆振动频繁，编织线容易断开，有时线已经断了，但棉芯线仍然保持连接。这种编织线不容易买到，可以用较长的软电线代替。
3. The speaker wire of professional audio equipment is broken. Due to the frequent vibration of the speaker tray, the braided wire is easy to break, sometimes the wire has broken, but the cotton core wire still remains connected. This braid is not easy to buy and can be replaced by longer flexible wires.
4、音圈烧坏了。如果扬声器引线的电阻接近0&翱尘别驳补;，没有&濒诲辩耻辞;咔嗒&谤诲辩耻辞;声，说明音圈烧坏了。更换音圈前，应先磁隙中的杂质，然后将新的音圈小心地放入磁隙中，调直音圈，边听边用强力胶将音圈上下固定，待音圈位置好后，将音圈与纸盆之间的间隙用胶水填满将强力胶涂到一半左右，然后密封防尘罩，将扬声器纸盆放上去，后即可正常使用。
4. The voice coil is burnt out. If the resistance of the speaker lead is close to 0 Ω， There is no "click" sound, indicating that the voice coil is burnt out. Before replacing the voice coil, you should first remove the impurities in the magnetic gap, then carefully put the new voice coil into the magnetic gap, straighten the voice coil, and fix the voice coil up and down with strong glue while listening. When the voice coil is in a good position, fill the gap between the voice coil and the paper basin with glue, apply the strong glue to about half, then seal the dust cover, and put the speaker paper basin on it. It can be used normally after one day.
二、音响设备声音时有时无
2、 Professional audio equipment sometimes has no sound
1、扬声器导线不好。它通常是由于发霉、断裂或音圈引线焊接不好引起的。当纸盆频繁振动时，断点时而相连，时而断开，形成不规则响声、无响声的断层。
1. The speaker wires are not good. It is usually caused by mildew, fracture or poor welding of voice coil lead. When the paper basin vibrates frequently, the breakpoints are sometimes connected and sometimes disconnected, forming irregular and noiseless faults.
2、音圈导线断裂或即将短路。
2. The voice coil wire is broken or about to be short circuited.
3、功放输出插座接触不好或音频输入线断裂。
3. Poor contact of power amplifier output socket or broken audio input line.
