可以是根據(jù)現(xiàn)場環(huán)境來指定方案，如果不觀察實際現(xiàn)場的環(huán)境很難做出理想的選型和喇叭分點布置的方案，關(guān)于吸頂音箱之間安裝的間距可以參考行業(yè)里這么一條：每兩個喇叭之間距離為喇叭到地面的距離兩倍，這樣的裝法通?？梢詽M足全場的播放聲音均勻。 </p> <p> 根據(jù)不同的場館環(huán)境配置吸頂音箱的功率和吸頂音箱分點的布置，需要考慮到整個場所內(nèi)的收聽者經(jīng)常所在區(qū)域位置，比如是經(jīng)常移動還是站著的多或坐著的多，整個場所環(huán)境背景的噪音大小等一些因素。 </p> <p> 天花揚聲器的靈敏度級在88～93dB之間；額定功率為3～10W。以90dB/8W匡算，在離揚聲器8m處的聲壓級約為81dB。以上匡算未考慮早期反射聲群的貢獻，佛山工廠吸頂音箱哪家好。在室內(nèi)，早期反射聲群和鄰近揚聲器的貢獻可使聲壓級增加2～3dB左右，佛山工廠吸頂音箱哪家好。 </p> <p> 根據(jù)以上近似計算，在天花板不高于3m的場館內(nèi)，天花揚聲器大體可以互相距離5～8m均勻配置。如果*考慮背景音樂而不考慮緊急廣播，則該距離可以增大至8～12m，佛山工廠吸頂音箱哪家好。 </p> <p> <br /> 吸頂音箱應(yīng)用于餐廳、車站、學(xué)校等場所的背景音樂、公共廣播系統(tǒng)，并逐漸走入家庭背景音樂系統(tǒng)中使用。佛山工廠吸頂音箱哪家好</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="佛山工廠吸頂音箱哪家好,吸頂音箱" src="https://tyunfile.71360.com/UploadFile/yyfkj8888/637437949186936297/7698011.png"></div><p> 吸頂音箱和功放怎么搭配 </p> <p> 吸頂音箱、功放之間有兩個匹配問題： </p> <p> 1.對功放必須阻抗匹配：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。 </p> <p> 2.對喇叭必須功率匹配：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。 </p> <p> 因此：3.如果4個8Ω喇叭如果全部并聯(lián)接到功放上，阻抗只有2Ω，會燒毀功放； </p> <p> 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)單獨關(guān)斷1只喇叭，要關(guān)就要同時關(guān)兩個。 </p> <p> 5.比較合適的方案用兩個喇叭并聯(lián)為4Ω，接到功放上阻抗合理，功率也基本匹配，關(guān)掉一個后阻抗成為8Ω，從功放得到的功率也會相應(yīng)減少，不至于過載。如果有4個喇叭，那必須是關(guān)掉兩個，即只能同時開兩個，開更多的喇叭就變成上面所說，會損壞功放。 </p> <p> 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）來匹配也算是一個方案，不過頻響會變差些。 </p> <p> <br /> 佛山工廠吸頂音箱哪家好吸頂音箱的一些基礎(chǔ)參數(shù)：功率、頻率響應(yīng)、靈敏度、阻抗、開孔尺寸等等。</p><div style="width:100%;text-align:

吸頂音箱一般由防塵蓋、音盆、音圈、振動板、盆架、接線柱、上下導(dǎo)磁極片、磁鋼組成。 </p> <p> 2、盆架:盆架材料類型及特點如下： </p> <p> 1）鐵皮：價格較低。 </p> <p> 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

A.內(nèi)磁式吸頂音箱磁場在喇叭磁路內(nèi),在喇叭的外部不會有磁場，適用于易受磁場影響的地方;B.外磁式吸頂音箱磁場在揚聲器外,沒有作防磁處理,因此在喇叭的外部有較強的磁場,為了使電聲效率更高,大音箱喇叭都是用大體積強磁力的外磁喇叭單元。 </p> <p> 藍(lán)牙無線吸頂音箱聲音解析力高，頻響寬。塑料外殼采用一體化的開孔設(shè)計思路，有源吸頂音箱防水設(shè)計，符合聲學(xué)原理，更好保障喇叭發(fā)聲音質(zhì)。簡單大方的白色設(shè)計，符合家庭裝修的多樣匹配。隨意匹配手機、平板等藍(lán)牙設(shè)備，音樂家在家中為您獨奏，體驗將起居室變?yōu)橐魳窂d頭等座的奇妙旅程。深圳市銀一鋒——吸頂音箱專業(yè)生產(chǎn)廠家。羅湖區(qū)別墅吸頂音箱批發(fā)</p><p style="text-indent:25px">吸頂音箱只是指一種安裝在天花板上的電聲轉(zhuǎn)換器件，就是喇叭，需要音源、功放系統(tǒng)來驅(qū)動發(fā)聲。佛山工廠吸頂音箱哪家好</p><p> 消防廣播與消防吸頂音箱區(qū)別,消防廣播與消防喇叭其實區(qū)別不大，普通吸頂音箱也可用在消防廣播上，但是要滿足消防廣播播放時的音量就可以了。 </p> <p>

民用建筑內(nèi)揚聲器應(yīng)設(shè)置在走廊和大廳等公共場所。每個揚聲器的額定功率不應(yīng)小于3瓦，其數(shù)量應(yīng)能保證從一個防火分區(qū)內(nèi)的任何部位到較近一個揚聲器的距離不大于25米。走道內(nèi)很后一個揚聲器至走道末端的距離不應(yīng)大于12.5米。 </p> <p> 對于消防廣播系統(tǒng)的介紹： </p> <p> 一、消防廣播系統(tǒng)也叫應(yīng)急廣播系統(tǒng)，是火災(zāi)逃生疏散和滅火指揮的重要設(shè)備，在整個消防控制管理系統(tǒng)中起著極其重要作用。 </p> <p> 二、在火災(zāi)發(fā)生時，應(yīng)急廣播信號通過音源設(shè)備發(fā)出，經(jīng)過功率放大后，由廣播切換模塊切換到廣播指定區(qū)域的音箱實現(xiàn)應(yīng)急廣播。 </p> <p>
