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，廣州吸頂音箱質(zhì)量，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(dá)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，廣州吸頂音箱質(zhì)量.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，廣州吸頂音箱質(zhì)量。

接在放大電路末端與吸頂音箱之間，應(yīng)該叫做輸出變壓器，是用于匹配放大電路與揚聲器阻抗專的。通常，放大電屬路末端輸出阻抗（電壓）較大而輸出電流較小。 </p> <p> 而動圈吸頂音箱的結(jié)構(gòu)決定著它的音圈圈數(shù)較少，低阻抗，需要較大電流。 </p> <p> 常用于變換電壓或變換負(fù)載的阻抗。 </p> <p> 變壓器前后級阻抗若不匹配，會引起反射而導(dǎo)致信號失真。為了使負(fù)載獲得功率，負(fù)載阻抗通過輸出變壓器的阻抗，變換后應(yīng)與功率放大級要求的阻抗一致，不得過大也不得過小。同時，變壓器可以放大電壓，但電壓變化后，功率卻因變壓器有損耗而減小了。這樣，它就不能帶動較大的負(fù)載。所以音頻變壓器并不能代替電子音頻信號放大器。 </p> <p> <br /> 廣州吸頂音箱質(zhì)量耳機(jī)的性能是有個上限的，不像吸頂音箱可以比較容易實現(xiàn)多單元及復(fù)雜的振膜材料構(gòu)成和多路分頻。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="廣州吸頂音箱質(zhì)量,吸頂音箱"

2）壓鑄：不易變形。 </p> <p> 3）合成材料：重量輕且不宜變形。 </p> <p> 3、音圈架:大多是鋁片。由于音圈架需要考慮散熱（音圈工作是產(chǎn)生熱量），鋁片散熱好，重量輕，不變形。也有用紙質(zhì)的，但是已被淘汰?，F(xiàn)在還有一種KLSV環(huán)氧樹脂板，有較好的表現(xiàn)。 </p> <p> 4、磁鐵 </p> <p> 1）鐵氧體：傳統(tǒng)的很常用，如沒有其他的限制，可以用鐵氧體。特點是體積大，價格低。 </p> <p> 2）釹磁：即褐釹鐵硼，也稱太空磁，其磁性是鐵氧體的7倍。常見的“”揚聲器就是釹磁的。其缺點是：不穩(wěn)定，易被消磁，所以不能代替鐵氧體。 </p> <p> 3）鍶磁：特點是效率高，但其體積做不大，因而只在高音揚聲器上用。 </p><p
