成都夜总会常见的七种音响故障及其解决办法

2018-03-31 10:13

  

一般来说,成都夜总会音箱系统出现的故障概率比较小,但是我们还是需要了解下,以便音箱故障的时候我们都能进行简单的处理。成都夜总会音箱主要有以下三种常见的故障。

  一、音箱无声

  成都夜总会音箱无声一般有以下四种情况:音箱接线断裂、分频器异常、音圈断裂或烧毁以及扬声器引线断。

  音箱接线断裂会造成无声故障,这是因为扬声器单元没有激励电压;而分频器可能发生引线接头虚焊、分频电容短路等也会出现无声;用万用表RX1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,露出铜线后再测,如果扔不同,则说明音圈内部断线;

  由于扬声器纸盆振动频繁,引线易折断,引线的材质选择、长度等都非常重要。用万用表RX1档测量扬声器引线,若阻值接近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,边试听边用强力胶固定音圈的上下位置,待音圈至于最佳位置后,用强力胶将音圈与纸盆的间隙填满至一半左右,封好防尘盖,将扬声器纸盘向上,放置一天后即可正常使用。

  二、音箱声音时有时无

  成都夜总会音箱时有时无的断音现象一般有以下三种请况:扬声器引线接触不良、导磁芯柱松脱以及分频器异常。

  一般来说,音圈引线材料的问题或焊接的时候没焊好,纸盆振动频繁时就会形成时响时不响故障;当扬声器的导磁芯柱松脱时,会被导磁板吸向一边,使音圈受挤压而阻碍正常发声。检修时可用手轻按纸盘,如果按不动,则可能是音圈被芯柱压住,需拆卸并重新粘固后才能恢复使用;当分频器中有元件有问题时,相应频段的信号受阻,该频段扬声器出现音量小故障。应重点检查与低音扬声器并联的分频电容是否短路,以及与高音扬声器并联的分频电感线圈是否层间短路。

  三、音箱声音异常

  成都夜总会音箱声音异常一般有以下四种情况:音箱磁隙有杂物、音圈擦芯、纸盆破裂以及箱体不良

  如果磁隙内有杂物,音圈就会与杂物相磨擦,就会造成异音。箱体密封性差,会影响播放的效果,产生破裂声。

以上就是成都夜总会预订网为大家分享的“成都夜总会音箱出现故障有哪些原因”的内容了,相信大家对音箱出现的故障原因有一定了解了吧,下次遇到这几种情况的时候相信大家就能对故障进行排查和解决了。

 四、系统总电源故障:

  使用成都夜总会音箱设备场所的电源设置是很重要的,一般都会申请安装三相动力电源,这样如果其中一个出现 故障时不至于整个系 统都瘫痪。音响系统和灯光最好要有各自的电源,否则容易产生干扰。如果可以的话, 音响系统中的各个设备最好设置独立电源 ,用相应的空气开关控制,这样开关设备会更加方便。

  五、设备分电源故障

  成都夜总会的音响比较常见的就是变压器和连接设备的电源出现问题,可以更换一个来排除故障,还有就是设备相连接的 插座、电源时序器等 有问题,特别是在流动演出时发生机率比较高。当然,排除以上情况,如果是设备内部 本身的电路部分故障,只有请专业的维修 人员或设备供应商来保修。

  六、电源稳压、接插设备故障

如果成都夜总会的音响系统配置了稳压器等电源处理设备,那么一旦稳压器的质量不好,稳压功率达不到标准,这样 也容易出现故障。

Generally speaking, the failure probability of the Chengdu night club sound box system is relatively small, but we still need to understand, so that when the sound box failure, we can do a simple process. There are mainly three kinds of common faults in Chengdu nightclub speakers.            One, the sound box is silent            There are four kinds of situations in Chengdu nightclub speakers: silence of speaker wiring, abnormal frequency dividers, breakup or burn of voice coil, and speaker wire break.            The fault of the box wiring will cause no sound fault, which is because the speaker unit has no excitation voltage, and the frequency divider may have a silent welding of the lead joint, the frequency divider capacitance short circuit, and so on. Using the multimeter RX1 gear to measure the loudspeaker lead wire welding piece, if the resistance value is infinity, the lacquer can be scraped open at the two ends of the small knife, exposing the copper wire and remeasuring, if the throw is different, it is explained that the throw is different. The inner broken line of the sound circle;            Due to the frequent vibration of loudspeaker, the lead wire is easily broken, and the material selection and length of the lead wire are all very important. If we use the multimeter RX1 file to measure the speaker lead, if the resistance is close to 0 ohms and there is no "click", it indicates that the voice coil is burned. Before replacing the sound circle, we should first remove the magnetic gap in the magnetic gap, and then carefully put the new ring into the magnetic gap, the positive ring, the edge test and the top and down position of the fixed ring with the strong glue. After the best position, the gap between the sound circle and the paper basin is filled to about half, sealing the dust cover, and placing the paper disc up, then placing it normally after a day.            Two. Sometimes there is no sound in a sound box.            There are usually three kinds of interruptions in Chengdu nightclub speakers: the poor contact of speaker leads, loosening of core guides and abnormal frequency dividers.            Generally speaking, the problem of the sound coil lead material or the welding is not welded well. When the vibration of the paper basin is frequent, the failure is not sound; when the core column of the loudspeaker is loosened, the magnetic plate will be sucked to one side, and the ring is squeezed to obstruct the normal sound. If it is not moved, it can be pressed by the core column, which should be disassembled and rebonded to restore use. When there is a problem in the frequency divider, the signal of the corresponding frequency band is blocked, and the frequency band loudspeaker has a small volume failure. It is important to check whether the shunt capacitor is short circuited in parallel with the loudspeaker, and whether the interlayer inductor coil is parallel to the tweeter and whether it is interlayer short circuit.            Three. Abnormal sound of sound box            There are four cases of abnormal sound in Chengdu nightclub. There are litter, voice coil, core, broken basin and bad box.            If there are impurities in the magnetic gap, the voice coil will rub with the debris and cause the abnormal sound. The poor sealing capacity of the box will affect the effect of playing and produce cracking.            The above is the Chengdu night club reservation network for everyone to share the "Chengdu night club sound box malfunction of what reasons" content, I believe you have a certain understanding of the reasons for the failure of the sound box, the next time you meet these cases, we believe that you can check and solve the fault.            Four. The total power failure of the system:            It is very important to use the power setting of the KTV sound box equipment. In general, it will apply for the installation of three phase power supply, so that if one of them fails, the whole system is not paralyzed. Sound system and lighting should have their own power supply, otherwise it will cause interference. If it is possible, each device in the sound system should be set up independent power supply and controlled by the corresponding air switch, so that the switchgear will be more convenient.            Five. Fault of equipment power supply            More common is the power supply problems of transformer and connection equipment, can be replaced to remove the fault, and the equipment connected to the socket, power timing device, and other problems, especially in the flow performance is relatively high. Of course, if the above conditions are excluded, only the professional maintenance personnel or equipment suppliers will be required to guarantee the parts of the circuit itself.            Six. Failure of power supply voltage regulator and plug - in equipment            If the sound system is equipped with a voltage regulator and other power processing equipment, if the quality of the pressurizer is not good, the voltage of the voltage regulator can not reach the standard, so it is easy to fail.            Seven. Circuit fault of sound system            First, the quality of the connection line is better, and try to buy reliable power connection lines, and save unnecessary trouble.            Second, the signal connection line should not be too hard to tear the wire when installing, in order to prevent damage to the wire. Of course, it does not rule out the problems caused by other reasons. The best way is to put several spare lines as much as possible when the line is placed.            In addition, when welding signal line, ensure the correct butt between various signal lines and their corresponding plugs. Pay attention to the welding quality of each solder joint. After the signal line is welded well, it will be detected by the multimeter, and the short circuit or circuit breakage will be seen.
