一套的音響設備，是需要多種設備，一起組合在一起，常用的產品分別是揚聲器、分頻器、箱體、吸聲材料等，這么多的組合設備，交叉的地方比較多，因此音響出現故障的幾率是比較高，那么大家知道音響設備出現故障后該怎么解決嗎?對此了解多少呢?接下來我們一起來看看吧!
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、無聲
1、 Silent
1、音頻線路斷開或分頻器異常。音頻線路斷開后，揚聲器單元沒有勵磁電壓，這將導致無聲故障。分壓器一般不易斷開，但引線接頭可能脫焊，分壓器電容可能短路。
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、音圈壞了。用萬用表R×1測量揚聲器引線的焊盤。如果電阻為∞，用小刀刮掉音圈兩端引線的密封漆，露出裸銅線，然后重新測量。如果仍然不工作，則表示音圈內部導線斷開;如果測量打開并有“咔嗒”聲，則表示音圈導線開路。焊接線頭，然后將其與靠近音圈繞組的另一段漆包線焊接。
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、音響設備揚聲器導線斷了。由于音箱紙盆振動頻繁，編織線容易斷開，有時線已經斷了，但棉芯線仍然保持連接。這種編織線不容易買到，可以用較長的軟電線代替。
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、音圈燒壞了。如果揚聲器引線的電阻接近0Ω，沒有“咔嗒”聲，說明音圈燒壞了。更換音圈前，應先磁隙中的雜質，然后將新的音圈小心地放入磁隙中，調直音圈，邊聽邊用強力膠將音圈上下固定，待音圈位置好后，將音圈與紙盆之間的間隙用膠水填滿將強力膠涂到一半左右，然后密封防塵罩，將揚聲器紙盆放上去，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、音響設備聲音時有時無
2、 Professional audio equipment sometimes has no sound
1、揚聲器導線不好。它通常是由于發霉、斷裂或音圈引線焊接不好引起的。當紙盆頻繁振動時，斷點時而相連，時而斷開，形成不規則響聲、無響聲的斷層。
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、音圈導線斷裂或即將短路。
2. The voice coil wire is broken or about to be short circuited.
3、功放輸出插座接觸不好或音頻輸入線斷裂。
3. Poor contact of power amplifier output socket or broken audio input line.
音響設備出現故障后的解決辦法，上述內容中已經為大家詳細的總結完了，如果您也遇到了這樣的問題，可以參考上面的問題進行解決。
