打開(kāi)音響的電源開(kāi)關(guān)，喇叭沒(méi)有正常開(kāi)機時(shí)“砰”的一聲開(kāi)機聲。打開(kāi)MP3播放器，調整音量，音響設備也沒(méi)有任何聲音。這種故障比較常見(jiàn)，開(kāi)機后音響設備沒(méi)有聲音。我們如何判斷
山東音響設備是真的壞了么?
Turn on the power switch of the audio system, and the horn does not make a "bang" sound when it is turned on normally. Turn on the MP3 player, adjust the volume, and there is no sound from the audio equipment. This kind of fault is quite common. The audio equipment has no sound after startup. How can we judge whether the professional audio equipment in Shandong is really broken?
在給音響設備加電之前，把音量點(diǎn)位品旋大位置，在打開(kāi)電源開(kāi)關(guān)時(shí)，注意音響設備是否有“砰”的一聲。如果有，說(shuō)明音響設備沒(méi)有什么問(wèn)題，電源是好的。
Before powering up the audio equipment, turn the volume point to the high position. When turning on the power switch, pay attention to whether the audio equipment has a "bang". If yes, there is no problem with the audio equipment and the power supply is good.
沒(méi)有聲音可能是聲卡的驅動(dòng)程序或聲音故障，也可能是被靜音了或者音量過(guò)小，再者就是信號線(xiàn)插頭沒(méi)有插接好，或者信號線(xiàn)斷線(xiàn)。還有就是，如果我們把信號線(xiàn)的插頭接觸機箱的金屬部分時(shí)，音響設備就會(huì )傳出“嗡嗡”的交流聲，特別明顯。
No sound may be caused by the driver of the sound card or the sound fault, or it may be muted or the volume is too low. In addition, the signal line plug is not plugged properly, or the signal line is disconnected. Also, if we contact the plug of the signal line with the metal part of the chassis, the audio equipment will emit a "buzzing" AC sound, which is particularly obvious.
音響界有“內行看質(zhì)量、外行掂重量”之說(shuō)，重的音箱肯定比輕的音箱要好些。好的音箱大多是以18mm，25mm的MDF粒子板打造，高檔旗艦級音箱則是以紫檀、黃柚之類(lèi)的超重實(shí)木或多層復合膠合板來(lái)打造，所以重量非常驚人，一對音箱凈重就達五六十公斤。劣質(zhì)音箱多半采用質(zhì)地松軟的刨花板甚低劣的紙膠板，故而重量一般較輕。
There is a saying in the audio industry that "professionals look at the quality and laymen weigh the weight". Heavy speakers are definitely better than light speakers. Good speakers are mostly made of 18mm and 25mm high-quality MDF particle boards, while high-grade flagship speakers are made of overweight solid wood such as red sandalwood and yellow grapefruit or multi-layer composite plywood, so the weight is very amazing. The net weight of a pair of speakers is 50 to 60 kilograms. Most of the low-quality speakers use soft particleboard or even inferior paper plywood, so the weight is generally light.
另外，一些不良商家也會(huì )利用消費者這種習慣，在箱體灌注沙石水泥增重，掂重量一定要仔細。更多相關(guān)內容就來(lái)我們網(wǎng)站

In addition, some unscrupulous businesses will also take advantage of this habit of consumers to pour sand and gravel cement into the box to increase the weight, and the weight must be carefully weighed. For more information, please visit our website http://m.djfrj.net.cn Consult and understand!
