系統(tǒng)構(gòu)成簡單的音響系統(tǒng)包括3個環(huán)節(jié)：音源、功率放大器和音箱（吸頂音箱）。音源指聲音播放設(shè)備如收音機、卡座、CD機、VCD、DVD、MP3等。對于電腦而言，光驅(qū)和聲卡都屬音源設(shè)備。一般音源設(shè)備的輸出電壓較小，大約在數(shù)百毫伏到兩伏之間，如果直接接音箱可能聲音很小甚至根本無聲。而且由于音箱（吸頂音箱）的阻抗一般很低，絕大多數(shù)在4~8歐姆之間，一些設(shè)計比較特殊的音箱（吸頂音箱）在某些頻段的阻抗甚至不到兩歐姆，接近短路，極易使音源設(shè)備過載，嚴重時甚至可能造成音源設(shè)備的損壞。因此，必須在音源和音箱之間加一級功率放大器，將音源輸出的微弱信號放大到足夠的功率去推動音箱（吸頂音箱），使音箱（吸頂音箱）發(fā)出足夠的音量。同時功放具有較高的輸入阻抗和較低的輸出阻抗，可以在音源和音箱（吸頂音箱）之間起到緩沖的作用，既不會使音源設(shè)備過載，又能輕易推動音箱（吸頂音箱）。寶安區(qū)店鋪吸頂音箱吸頂音箱圓形塑膠盆架，同軸高音設(shè)計，多功能選擇，可以安裝在不同厚度的天花板上。</p><div

style="text-indent:25px"><p>吸頂音箱重要指標1<p>頻率響應(yīng)(Hz)：相信這項指標對于大部分的讀者來說并不陌生。因為它是衡量音箱優(yōu)劣的重要指標之一。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。而人耳能聽到的聲音范圍在20Hz—20kHz之間。但實際上來看，目前的產(chǎn)品基本上很少能夠達到這個指標，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。而對于一般的入墻喇叭來說，其低頻下限能達到50Hz已經(jīng)算是不錯了，而對于50Hz以下的頻率的重現(xiàn)基本上是通過外加低音炮來完成的。吸頂音箱品牌哪個好？----鷹霸星（深圳市銀一鋒科技）。</p><div

2、送話器兩極漏電（重焊）：1、機板有放電現(xiàn)象（清洗。2、更換質(zhì)量較差機殼引起（更換質(zhì)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 </p> <p> 3、檢查功放，檢查接線等等多方面排查客廳有必要安裝吸頂吸頂音箱嗎？龍華區(qū)餐廳吸頂音箱公司</p><p style="text-indent:25px">吸頂音箱并不是越貴越適合，越貴音質(zhì)越好，“量體裁衣”、滿足自己需求的音響才是合適的。龍華區(qū)餐廳吸頂音箱公司</p><p> 吸頂音箱的安裝距離計算方法 </p> <p> 作為廣播系統(tǒng)中的常用揚聲器，其安裝距離一直沒有具體確定，業(yè)界一般按照吸頂音箱的覆蓋角度和樓層高度來算。樓層高度越高吸頂音箱間距就可以適當(dāng)大一些，吸頂音箱的功率相應(yīng)也要選擇大一些的；樓層越低，吸頂音箱的間距越小，功率就可以選擇小一些的吸頂音箱，正常按照90度覆蓋角度結(jié)合樓層的高度在3米左右，達到一個聲音簡單的覆蓋7-8米一只就可以了，要聲場均勻一些，我們通常采用一個粗略的算法就是：樓層高度*2-1基本能滿足要求。 </p> <p> 走廊吸頂音箱間距則按層高的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、會議室、餐廳、商場、宴會廳、天臺花園等處凡納入公用廣播系統(tǒng)的地方，宜裝設(shè)3~12瓦的吸頂音箱或小型音柱。層高為2.5米左右的宜用3W的吸頂音箱，間距為層高的2~2.5倍；層高為4米以上時，宜采用3~5W的吸頂音箱。 </p> <p> 吸頂音箱的安裝距離并沒有硬性規(guī)定，以上資料*供各位參考，實際使用中可根據(jù)上述算法和實際環(huán)境確定。龍華區(qū)餐廳吸頂音箱公司</p><p
