style="font-family:"font-size:16px;">作為廣播系統(tǒng)中的常用揚(yáng)聲器，其安裝距離一直沒有具體確定，業(yè)界一般按照天花喇叭的覆蓋角度和樓層高度來算。樓層高度越高天花喇叭間距就可以適當(dāng)大一些，天花喇叭的功率相應(yīng)也要選擇大一些的；樓層越低，天花喇叭的間距越小，功率就可以選擇小一些的天花喇叭，正常按照90度覆蓋角度結(jié)合樓層的高度在3米左右，達(dá)到一個(gè)聲音簡(jiǎn)單的覆蓋7-8米一只就可以了，要聲場(chǎng)均勻一些，我們通常采用一個(gè)粗略的算法就是：樓層高度*2-1基本能滿足要求。</span> </p> <p> <span style="font-family:"font-size:16px;">走廊天花喇叭間距則按層高的2.5倍考慮，有天花板的環(huán)境一般宜吸頂安裝。在樓層走廊的兩端門廳、會(huì)議室、餐廳、商場(chǎng)、宴會(huì)廳，光明區(qū)同軸天花喇叭、天臺(tái)花園等處凡納入公用廣播系統(tǒng)的地方，宜裝設(shè)3~12瓦的天花喇叭或小型音柱，光明區(qū)同軸天花喇叭。層高為2.5米左右的宜用3W的天花喇叭，間距為層高的2~2.5倍；層高為4米以上時(shí)，宜采用3~5W的天花喇叭。</span> </p> <p> <span style="font-family:"font-size:16px;">天花喇叭的安裝距離并沒有硬性規(guī)定，以上資料*供各位參考，實(shí)際使用中可根據(jù)上述算法和實(shí)際環(huán)境確定。</span> 天花喇叭布置應(yīng)根據(jù)建筑功能、體型、空間高及觀眾席等因素確定，光明區(qū)同軸天花喇叭，一般分為：分散布置、集中布置、混合布置。光明區(qū)同軸天花喇叭</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

style="font-family:"font-size:16px;">由于現(xiàn)時(shí)市面上天花喇叭的種類較多，對(duì)于一般的消費(fèi)者而言可能會(huì)提出一些疑問。究竟我應(yīng)該如何進(jìn)行選擇?而在選擇的時(shí)候必須注意些什么呢?在此，我們就針對(duì)這部分想購置天花喇叭的消費(fèi)者總結(jié)出以下一些要點(diǎn)供大家參考。</span> </p> <p> <span style="font-family:"font-size:16px;">頻率響應(yīng)(Hz)：它是衡量音箱優(yōu)劣的重要指標(biāo)之一。理論上，音箱的頻率響應(yīng)越寬就意味著能重放出更多的聲音信號(hào)。而人耳能聽到的聲音范圍在20Hz—20kHz之間。但實(shí)際上來看，目前的產(chǎn)品基本上很少能夠達(dá)到這個(gè)指標(biāo)，尤其是在低頻的下限方面，要重現(xiàn)20Hz低頻是相當(dāng)困難的事情。</span> </p> <p> <span style="font-family:"font-size:16px;">靈敏度(dB)：音箱的靈敏度是在特定頻率下對(duì)喇叭輸入1W(2.83V或1V)的功率，然后在喇叭正軸的位置測(cè)得的聲壓值。這個(gè)值相當(dāng)于喇叭的效率。在相同輸入功率的情況下，靈敏度越高的喇叭所輸出的聲壓會(huì)越高。</span> </p> <p> <span style="font-family:"font-size:16px;">功率承載能力(W)：現(xiàn)在幾乎廠家都會(huì)給出該款產(chǎn)品的功率承載能力又或者是推薦放大器功率等類似的參考指標(biāo)可活動(dòng)式高音單元設(shè)計(jì)：現(xiàn)時(shí)有部分的入墻喇叭的高音單元為可活動(dòng)式設(shè)計(jì)，這種設(shè)計(jì)可以根據(jù)消費(fèi)者的實(shí)際需要來對(duì)高音單元的指向角度進(jìn)行微調(diào)，以獲得更佳的音響效果。</span> </p> <p> <span style="font-family:"font-size:16px;">高、低音調(diào)節(jié)功能：這功能可以根據(jù)不同消費(fèi)者的聽音喜好以及聆聽空間的聲學(xué)特性作出適當(dāng)微調(diào)。</span> 光明區(qū)同軸天花喇叭天花喇叭聲音豐滿甜美；高音冰涼如水，細(xì)膩富有空靈感。</p><div

style="font-family:"font-size:16px;">天花喇叭、功放之間有兩個(gè)匹配問題：</span> </p> <p> <span style="font-family:"font-size:16px;">1.對(duì)功放必須阻抗匹配：喇叭的總阻內(nèi)抗應(yīng)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(duì)喇叭必須功率匹配：喇叭得到的功率應(yīng)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(gè)8Ω喇叭如果全部并聯(lián)接到功放上，阻抗只有2Ω，會(huì)燒毀功放；</span> </p> <p> <span style="font-family:"font-size:16px;">4.如果兩兩串聯(lián)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(guān)單獨(dú)關(guān)斷1只喇叭，要關(guān)就要同時(shí)關(guān)兩個(gè)。</span> </p> <p> <span style="font-family:"font-size:16px;">5.比較合適的方案用兩個(gè)喇叭并聯(lián)為4Ω，接到功放上阻抗合理，功率也基本匹配，關(guān)掉一個(gè)后阻抗成為8Ω，從功放得到的功率也會(huì)相應(yīng)減少，不至于過載。如果有4個(gè)喇叭，那必須是關(guān)掉兩個(gè)，即只能同時(shí)開兩個(gè)，開更多的喇叭就變成上面首一款所說，會(huì)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，當(dāng)然使用線路變壓器（定壓式喇叭用）來匹配也算是一個(gè)方案，不過頻響會(huì)變差些。</span> </p><p> <span style="font-family:"font-size:16px;">許多盆友覺得，天花喇叭音箱比不上傳統(tǒng)式落地箱或書架箱，由于他們：看上去很不技術(shù)專業(yè)。</span> </p> <p> <span style="font-family:"font-size:16px;">假如你覺得的是地鐵站、院校、大型商場(chǎng)用的那類，或者商場(chǎng)每到國家法定假日放點(diǎn)《好運(yùn)來》及其播發(fā)大營銷這類通告的天花喇叭，那的確不好。</span> </p> <p> <span style="font-family:"font-size:16px;">它是歸屬于公共廣播系統(tǒng)系統(tǒng)軟件，用的是定壓揚(yáng)聲器。說白了定壓揚(yáng)聲器是在喇叭前端開發(fā)加了一個(gè)電線間變壓器，這一變壓器的功效是把120V或是240V的廣播節(jié)目工作電壓轉(zhuǎn)化成合適喇叭工作中的工作電壓，因此定壓喇叭合適與定壓功放機(jī)（擴(kuò)音機(jī)）聯(lián)接，普遍用以長距離傳送的有線廣播場(chǎng)所。</span> </p> <p> <span style="font-family:"font-size:16px;">家庭裝的天花喇叭吸頂音箱則徹底不一樣，選用的是定阻揚(yáng)聲器，不加線間變壓器，是以電流量來促進(jìn)。其特性是電流量大，工作電壓小，適用近距模擬信號(hào)傳送，一般有4Ω和8Ω，規(guī)定揚(yáng)聲器的電阻器與功放機(jī)相符合，吸頂音箱多運(yùn)用于音樂背景系統(tǒng)軟件、家庭影院套裝。它運(yùn)用墻壁或吊頂天花板做為自然共震內(nèi)腔，吸頂音箱響聲復(fù)原度較高，適用家居家具、會(huì)館、酒店餐廳等。</span>

style="font-family:"font-size:16px;">開孔直徑按照各吸頂音箱規(guī)定的開孔尺寸，實(shí)際施工中，可以稍微大一點(diǎn)點(diǎn)，這樣安裝和取出更容易每兩個(gè)吸頂音箱之間的距離為音箱到地面距離的兩倍，通常這樣的裝法能滿足全場(chǎng)的播放聲音均勻</span> </p> <p> <span style="font-family:"font-size:16px;">客廳吊頂一是要看幾個(gè)喇叭，二是看喇叭的阻抗是多少歐姆的，并且應(yīng)該知道功放輸出要求阻抗是多少的，并且功放是幾聲道，如果大于四聲道，可以直接將四個(gè)喇叭分別連接功放的一個(gè)聲道，如果四個(gè)喇叭只使用兩路輸出，就將兩只喇叭串聯(lián)后接在功放一路上即可。</span> </p> <p> <span style="font-family:"font-size:16px;">吸頂音箱線路布設(shè)比較好跟電工布線一起做，喇叭線是弱電，應(yīng)該跟電工的強(qiáng)電(AC220V)不要靠得太近，穿PVC管的話，距離15~20厘米左右就可以了，出于干擾等因素，但總的走線路線應(yīng)該盡量跟隨強(qiáng)電或弱電路線，不顯的雜亂，</span> </p> <p> <span style="font-family:"font-size:16px;">喇叭線路可以固定在天花板的吊筋上，音箱點(diǎn)的位置在實(shí)際施工過程中還需要考慮到各種燈的位置，以及天花板封頂?shù)脑煨偷?，若喇叭安裝位置跟燈位重復(fù)影響美觀。</span> </p> <p> <span style="font-family:"font-size:16px;">系統(tǒng)調(diào)試，系統(tǒng)調(diào)試需要注意的是：系統(tǒng)開機(jī)運(yùn)行前須檢查線路，當(dāng)然這個(gè)工作在線路布置好以后就應(yīng)該先檢測(cè)一遍線路的。</span>
