style="font-family:"font-size:16px;">1.對功放必須阻抗匹配：喇叭的總阻內抗應該等于功容放阻抗，至少喇叭不得小于功放阻抗，可以大于功放阻抗。否則容易燒毀功放。</span> </p> <p> <span style="font-family:"font-size:16px;">2.對喇叭必須功率匹配：喇叭得到的功率應該等于它的額定功率，不得大于，可以小于。否則容易燒毀喇叭。</span> </p> <p> <span style="font-family:"font-size:16px;">因此：3.如果4個8Ω喇叭如果全部并聯接到功放上，阻抗只有2Ω，會燒毀功放；</span> </p> <p> <span style="font-family:"font-size:16px;">4.如果兩兩串聯再接功放，總體仍為8Ω，高于功放阻抗，功放安全，但是不能使用開關單獨關斷1只喇叭，要關就要同時關兩個。</span> </p> <p> <span style="font-family:"font-size:16px;">5.比較合適的方案用兩個喇叭并聯為4Ω，接到功放上阻抗合理，功率也基本匹配，關掉一個后阻抗成為8Ω，從功放得到的功率也會相應減少，不至于過載。如果有4個喇叭，那必須是關掉兩個，即只能同時開兩個，開更多的喇叭就變成上面首一款所說，會損壞功放。</span> </p> <p> <span style="font-family:"font-size:16px;">6.如果購買2Ω輸出阻抗的功放則問題解決，或者改用16Ω喇叭也可以解決問題，光明區(qū)天花喇叭接線，當然使用線路變壓器（定壓式喇叭用）來匹配也算是一個方案，不過頻響會變差些，光明區(qū)天花喇叭接線，光明區(qū)天花喇叭接線。</span> 有源天花喇叭特點：音質清晰、操作簡便、隨意匹配。光明區(qū)天花喇叭接線</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="光明區(qū)天花喇叭接線,天花喇叭"

style="font-family:"font-size:16px;">功率有兩種，一種是額定功率（RMS），一種是最大輸出功率（PMPO）。額定功率是指在不失真情況下，音箱能夠長期安全使用的最大功率值。正常使用的情況使用的也是這個數值，然而，市面上除了一些大型廠商會標出該值，其余大部分廠商標注的是最大輸出功率。而最大輸出功率，記住，天花喇叭的功率的大小，與音質的好壞沒有必然的聯系，功率的大小，**是決定了聲音的大小。</span> </p> <p> <span style="font-family:"font-size:16px;">阻抗</span> </p> <p> <span style="font-family:"font-size:16px;">阻抗是電阻和電抗的總和，電阻是指物體對電流的阻礙作用；電抗是指電容和電感阻礙電流的作用。聽音樂的話，阻抗過低，會造成電流過大，很容易造成聲音失真，所以，在選購的時候不宜買阻抗太低的，一般來說，天花喇叭的阻抗多設計為8歐姆，2、4、6或16歐姆，也比較常見。</span> </p> <p> <span style="font-family:"font-size:16px;">靈敏度</span> </p> <p> <span style="font-family:"font-size:16px;">靈敏度是指給音箱輸入1W功率時，在距離音箱正面垂直中軸線1M的距離所測試得來的聲壓級，單位是分貝（dB）。靈敏度越高的音箱，聲音失真的可能性要小得多，是音箱技術參數比較重要的指標之一。一般來說，普通的高保真音箱的靈敏度在86分貝左右，95分貝以上已經稱得上專業(yè)級別，選購音箱時可以參考。</span>

2、更換質量較差機殼引起（更換質量好機殼、交流聲。3、或用錫紙作屏蔽、尾插漏電（清洗。 3、燒炮仗聲。4。 2，降低功放功率）、干燥），一般來說有以下兩種情況這個看具體是什么聲音了、音頻周邊元件虛焊漏電。</span> </p> <p> <span style="font-family:"font-size:16px;">3、檢查功放，檢查接線等等多方面排查。</span>
