style="font-family:"font-size:16px;">同軸天花喇叭是在同一軸心上安裝了兩個揚聲器分別負責(zé)重放高音和中低音，而且這兩個揚聲器在振膜面上也要重合，由于其物理定位接近于點聲源，因此重放音樂的聲場定位就很理想。</span> </p> <p> <span style="font-family:"font-size:16px;">同軸天花喇叭產(chǎn)品是用一只同軸天花喇叭代替現(xiàn)行普通高、中、低音多個揚聲器系統(tǒng)的揚聲器產(chǎn)品，是揚聲器產(chǎn)品中的珍品系列，其性能參數(shù)遠遠優(yōu)于普通揚聲器，突出特點是高、中、低音全音域聲音的傳播相位保真度極高，由于相位保真度的提高，其聲音的位置感及聲音的位置移動感鮮明準確（既聲像移動，聲像定位準確，因為相位參數(shù)是決定聲音位置的），而音樂中眾多樂器發(fā)出聲音的各自位置也不易混亂，從而音樂還原優(yōu)良，這樣的揚聲器特別適合于重放 DVD 中 AC-3 標準家庭影院系統(tǒng)的音響效果及 Hi-Fi 重放，更適合于狹小空間環(huán)境下的使用（如摩托車音響系統(tǒng)）。由同軸揚聲器組成的音箱就是同軸音箱。</span> 廣州藍牙天花喇叭天花喇叭的結(jié)構(gòu)：由T鐵、華司、磁鐵、彈波，紙盆，音圈、防塵帽、膠水、電子線及其他安裝配件組成。</p><div

天花喇叭“無極調(diào)音開關(guān)”，就是線繞電位器，，這種開關(guān)一般負載功率只有回5W，按標準只能連接5W以下負載，但實際使用時連接2個6W喇叭也沒什么問題，因為喇叭幾乎沒有滿功率工作的時候。如果一個開關(guān)后面并聯(lián)的喇叭數(shù)量太多，容易燒壞線繞電阻。</span><span style="font-family:"font-size:16px;">（有人說定壓喇叭必須使用檔位開關(guān)，無級開關(guān)只能定阻天花喇叭用，雖然檔位開關(guān)和無級開關(guān)都是通過調(diào)節(jié)電阻改變音量，但由于里邊電阻不同的原因，造成定壓喇叭必須使用檔位開關(guān)，無級開關(guān)只能用于定阻喇叭，不知這說法是否正確），這種說法不正確，這兩種開關(guān)都是用于定壓線路，定阻喇叭的音量是通過調(diào)整功放電路的輸入信號實現(xiàn)的，在定阻攻防后串聯(lián)電阻降低音量會造成失真加大、更重要的是完全改變了功放輸出的負載阻抗。</span> </p><p> <span style="font-family:"font-size:16px;">定壓天花喇叭的相關(guān)概念</span> </p> <p> <span style="font-family:"font-size:16px;">定壓輸出的稱呼很容易造成認知誤差，在定壓放大器的應(yīng)用中是一個交流概念，滿功率輸出的是電壓有效值就是定壓放大器的額定電壓，既不是直流概念中的一直維持固定電壓電流隨信號變化，也不是交流概念中的交流電壓有效值恒定。</span> </p> <p> <span style="font-family:"font-size:16px;">定壓放大器輸出電壓按照其增益隨著輸入電壓的變化而變化，測試時施加1000Hz0.775Vrms正弦波信號在輸入端，輸出端在額定負載額定功率輸出的條件下，電壓有效值恒定為70Vrms/70.7vrms/100Vrms/120Vrms。</span> </p> <p> <span style="font-family:"font-size:16px;">定阻天花喇叭功率為10-60W，設(shè)正常使用時功率為20W，那么20*(30+24)=1080W,預(yù)留功率余量和線路損耗，建議用輸出阻抗4歐姆，輸出功率1500W左右的功放機。</span> </p> <p> <span style="font-family:"font-size:16px;">根據(jù)定壓功放的輸出電壓和功率，確定吸頂喇叭的輸入電壓和功率，如100V6W對應(yīng)黑、紅。</span> </p> <p> <span style="font-family:"font-size:16px;">布設(shè)總線與各單元連接，使全部單元極性相同（顏色對應(yīng)）地并聯(lián)在總線上，并確定各單元功率的總和小于定壓功放的輸出功率。</span> </p> <p> <span style="font-family:"font-size:16px;">將總線連接到定壓功放對應(yīng)電壓的輸出端子，如定壓功放輸出端上的COM、100V。</span> 天花喇叭并不是越貴越適合，越貴音質(zhì)越好，“量體裁衣”、滿足自己需求的音響才是其合適的。</p><div style="width:100%;text-align: center;"><img

style="font-family:"font-size:16px;">如果400平米只有8個點，我認為會出現(xiàn)有的位置聽不到聲音的問題。背景音樂內(nèi)主要播放的是中頻容和少量的高頻，因此，天花喇叭的口徑有6寸足夠了。另外，因為播放的是中頻和高頻，天花板距地面在2.5-4米的范圍，因此，每個天花喇叭的平均功率在10W以下及足夠了，但是布設(shè)的點要多一些，大約相隔10米一個。如果布點少，單點的功率高，就會出現(xiàn)有的區(qū)域很吵，影響客人的交談，有的地方卻無聲，起不到背景音樂的效果。</span> </p> <p> <span style="font-family:"font-size:16px;">天花喇叭的響度是不是跟口徑的大小也有關(guān)系，不**是要看功率</span> </p> <p> <span style="font-family:"font-size:16px;">簡單的理解：口徑越大，低頻效果越好，和響度沒有直接的關(guān)系。</span> </p> <p> <span style="font-family:"font-size:16px;">響度主要還是看當時的輸出功率。</span> </p> <p> <span style="font-family:"font-size:16px;">另外，口徑越小，聲音的指向性越好，作為背景音樂，需要弱指向性，因此也需要選擇較大口徑的音箱。</span> 廣州藍牙天花喇叭</p><p
