2、要正確選擇藍(lán)牙音箱喇叭的型號。如在廣場使用，應(yīng)選用高音藍(lán)牙音箱喇叭；在室內(nèi)使用，應(yīng)選用紙盆式藍(lán)牙音箱喇叭，并選好助音箱。也可在布置藍(lán)牙音箱喇叭的時(shí)候，要做到聲揚(yáng)勻且足夠的聲級，如用單只（點(diǎn)）藍(lán)牙音箱喇叭不能滿足需要，可多點(diǎn)設(shè)置，使每一位聽眾得到幾乎相同的聲音響度，提高聲音的清晰度。 </p> <p> 3、注意藍(lán)牙音箱喇叭的阻抗應(yīng)與輸出線路配合，具體做法可參看擴(kuò)音機(jī)一節(jié)。 </p> <p> 4、藍(lán)牙音箱喇叭得到的功率不要超過它的額定功率，否則，將燒毀音圈，或?qū)⒁羧φ裆?。電磁式和壓電陶瓷式藍(lán)牙音箱喇叭工作電壓不要超過30V。 </p> <p> 5、兩個(gè)以上的藍(lán)牙音箱喇叭放在一起使用時(shí)，必須注意相位問題，南山區(qū)背景音樂喇叭布置。如果是反相，南山區(qū)背景音樂喇叭布置，聲音將顯著削弱。測定藍(lán)牙音箱喇叭相位簡單方法利用高靈敏度表頭或萬用表的50~250μA電流擋，把測試表與藍(lán)牙音箱喇叭的接線頭相連接，雙手扶住紙盆，用力推動(dòng)一下，這時(shí)就可從表針的擺動(dòng)方向來測定它們的相位。如相位相同，南山區(qū)背景音樂喇叭布置，表針向一個(gè)方向擺動(dòng)。此時(shí)可把與正表筆相連的音圈引出頭作為“十”級。背景音樂喇叭可普遍用于學(xué)校、軌道交通、景區(qū)、商廈、機(jī)場及體育場館等室內(nèi)播音場所。南山區(qū)背景音樂喇叭布置</p><div

雖說藍(lán)牙音箱的兼容性基本100%支持現(xiàn)有藍(lán)牙設(shè)備，但還是要買之前查清楚自己的播放設(shè)備是否支持藍(lán)牙。傳輸距離：藍(lán)牙音箱的傳輸距離也是大家比較關(guān)心的問題。藍(lán)牙音箱的傳輸距離與藍(lán)牙版本無關(guān)，主要取決于技術(shù)的先進(jìn)程度。PowerClass2的標(biāo)準(zhǔn)傳輸距離10米；而升級的PowerClass1則將傳輸距離提升到100米，并且提供Hi-Fi立體聲效果。一般而言，手機(jī)與藍(lán)牙音箱的距離不會太遠(yuǎn)，比較保險(xiǎn)的傳輸距離約為10米以內(nèi)。市面藍(lán)牙音箱均達(dá)到10米標(biāo)準(zhǔn)。版本：消費(fèi)者采購藍(lán)牙音箱時(shí)，經(jīng)常會看到Bluetooth1.1、1.2、2.0、2.1、3.0、4.0等數(shù)字，這些數(shù)字表示著版本的不同，同時(shí)也表示著藍(lán)牙音箱抗干擾的能力。2012年以2.0普遍、3.0是新的主流、4.0則剛剛推出不久。藍(lán)牙版本不同，關(guān)乎接收信號的品質(zhì)。新版本更強(qiáng)調(diào)能克服雜訊干擾。新版本都可以向下兼容，消費(fèi)者選購時(shí)應(yīng)衡量價(jià)格和需求.

背景音樂喇叭效果影音室使喇叭布局方案，上全套的環(huán)繞聲揚(yáng)聲器，當(dāng)然這只是理想，而實(shí)際情況下，我們能拿到的房間都是別人挑剩下的，例如我們總是趕在酒窖的人，健身房的人，室內(nèi)高爾夫甚至雪茄等人后面來接影院，甚至有樓梯與電梯間的過道，頂層斜頂?shù)拈w樓等，正是如此才體現(xiàn)了影院環(huán)繞聲厲害的地方。 </p> <p> 全部揚(yáng)聲器墻面安裝>*環(huán)繞揚(yáng)聲器頂面安裝>*中置揚(yáng)聲器墻面安裝>所有揚(yáng)聲器頂面安裝。 </p> <p> 排列方式中置的重要性，每個(gè)公司也都會有自己的想法，我認(rèn)為中置的重要性更多一些，那也就強(qiáng)調(diào)了中置音箱的位置的重要性，那相對中置來說，前置左右揚(yáng)聲器可能也算是環(huán)繞聲揚(yáng)聲器了我們盡可能的使用透聲幕布，出發(fā)點(diǎn)更多也是強(qiáng)調(diào)中置位置的重要性，也就是水平高度的位置，當(dāng)屏幕過大時(shí)（例如院線）需要在中置與左右音箱之間位置增加揚(yáng)聲器補(bǔ)聲，思路是中置加寬而不是左右加寬。 </p> <p> 如果你是一個(gè)玩家，那使用多聲道環(huán)繞聲總歸還是比虛擬環(huán)繞聲來的直接，任何情況下都是要根據(jù)實(shí)際情況來調(diào)整揚(yáng)聲器的位置。 </p> <p> <br /> </p><p style="text-indent:25px"><p>37、家庭安裝了吸頂背景音樂喇叭，如何撤除的方法指導(dǎo)<p>1、關(guān)掉電源。在拆除工作進(jìn)行之前要先做好電源的關(guān)閉工作，確保實(shí)施環(huán)境的安全，不然會有觸電的危險(xiǎn)。（在撤除之前請務(wù)必保證電源關(guān)閉狀態(tài)）<p>2、拆除音響之前要先拆除外面的音響罩，音響罩外圈有有幾顆小的螺絲釘，旋轉(zhuǎn)下來即可，這樣就能將音響罩拆除下來。<p>3、吸頂音響的兩邊有兩個(gè)卡槽，一般是彈簧的，要用工具將那兩邊的卡槽弄下來，一邊一邊操作。如果看不到那個(gè)卡口，扒拉下來就能看到，要用技巧不能使用蠻力。<p>一般吸頂音箱兩邊都源有兩個(gè)卡子，也可能是彈簧的，也可能是用螺絲的，你把前面罩旋下來，可以看到內(nèi)壁兩側(cè)應(yīng)該有兩個(gè)口子。如果是彈簧的卡子用一字改刀伸進(jìn)去將它掰開，一邊一邊的取下來就可以了。有些型號的可能還需要把喇叭拆了才看得見留的卡子口。人體感應(yīng)背景音樂喇叭感應(yīng)高度為3-4米。避免靠近熱源和電磁干擾。</p><div

安裝背景音樂喇叭時(shí)，應(yīng)該注意些什么采用的是4－8歐姆的定阻喇叭，如果選用16歐姆喇叭，每個(gè)左聲道或者右聲道可以并聯(lián)兩個(gè)喇叭，如果選用4歐姆喇叭，每個(gè)左聲道或者右聲道只能接一個(gè)喇叭，而且音量不要開得過大，否則有可能燒毀背景音樂控制器。 </p> <p> 為了保證立體聲效果，安裝喇叭的時(shí)候需要考慮人在房間的活動(dòng)特點(diǎn)。例如，在客廳，將喇叭安裝在沙發(fā)兩側(cè)；在臥室，將喇叭安裝在床頭兩側(cè)；在書房，將喇叭安裝在書桌兩側(cè)；在餐廳，可以考慮將喇叭安裝在餐桌兩側(cè)。一般情況下，喇叭之間的距離保持在層高的3/1左右就會有比較好的立體聲效果。如果房間較大，可以考慮左聲道和右聲道分別接兩個(gè)8歐姆的喇叭，使音質(zhì)更加均勻，立體聲效果更好。背景音樂喇叭堅(jiān)固的比銹鋼硬件和防塵鋁面網(wǎng)。南山區(qū)背景音樂喇叭布置</p><p style="text-indent:25px">背景音樂喇叭高靈敏度，覆蓋范圍廣。南山區(qū)背景音樂喇叭布置</p><p>背景音樂喇叭的一些基礎(chǔ)參數(shù)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(gè)數(shù)值，然而，市面上除了一些大型廠商會標(biāo)出該值，其余大部分廠商標(biāo)注的是最大輸出功率。而最大輸出功率，記住，音箱的功率的大小，與音質(zhì)的好壞沒有必然的聯(lián)系，功率的大小，**是決定了聲音的大小，因此，結(jié)合場景，結(jié)合所需要的的面積進(jìn)行選購就行，正常來說15W~60W完全足夠，如果是臥室里使用，1瓦都能讓整個(gè)房間的人都聽的清楚。阻抗：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(shí)候不宜買阻抗太低的，一般來說，音箱的阻抗多設(shè)計(jì)為8歐姆，2、4、6或16歐姆，也比較常見。靈敏度：靈敏度是指給音箱輸入1W功率時(shí)，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(shù)參數(shù)比較重要的指標(biāo)之一。<p><br/>南山區(qū)背景音樂喇叭布置<p
