藍(lán)牙背景音樂喇叭相關(guān)介紹 </p> <p> 藍(lán)牙是一種低成本大容量的短距離無線通信規(guī)范。藍(lán)牙筆記本電腦，就是具有藍(lán)牙無線通信功能的筆記本電腦。藍(lán)牙這個(gè)名字還有一段傳奇故事呢。所以，藍(lán)牙也就成了溝通的代名詞。一千年后的現(xiàn)在，當(dāng)新的無線通信規(guī)范出臺時(shí)，人們又用藍(lán)牙來為它命名。 </p> <p> 藍(lán)牙概念。藍(lán)牙規(guī)范采用微波頻段工作，傳輸速率每秒1M字節(jié)，較遠(yuǎn)傳輸距離10米，通過增加發(fā)射功率可達(dá)到100米。藍(lán)牙技術(shù)是全球開放的，在全球范圍內(nèi)具有很好的兼容性，全世界可以通過低成本的無形藍(lán)牙網(wǎng)連成一體。 </p> <p> 藍(lán)牙技術(shù)不**運(yùn)用于電腦，像移動電話、數(shù)字相機(jī)、攝像機(jī)、打印機(jī)、傳真機(jī)、家電等許許多多電子設(shè)備都可以采用藍(lán)牙技術(shù)，實(shí)現(xiàn)無線連通，而不必拖一條尾巴（連接線）。隨著藍(lán)牙技術(shù)的普及，家庭裝修時(shí)不再為電器的布線而煩惱；使用家電時(shí)，不必為一大堆遙控器而頭疼，一部手機(jī)或是一把汽車鑰匙就能一切搞定；出門在外，公司的工作安排和家里親人的畫面可以隨時(shí)隨地獲得；打卡、繳費(fèi)不用排隊(duì)，從繳費(fèi)點(diǎn)附近經(jīng)過，不必進(jìn)門就可以輕松完成……藍(lán)牙技術(shù)的廣泛應(yīng)用將使我們的生活無比輕松。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。</p><div

背景音樂喇叭的安裝距離計(jì)算方法天花喇叭其分散的程度應(yīng)保證服務(wù)區(qū)內(nèi)的信噪比不小于15dB。通常，高級寫字樓走廊的本底噪聲約為48~52dB，超級商場的本底噪聲約58~63dB，繁華路段的本底噪聲約70~75dB?？紤]到發(fā)生事故時(shí)，現(xiàn)場可能十分混亂，為了緊急廣播的需要，即使廣播服務(wù)區(qū)是寫字樓，也不應(yīng)把本底噪聲估計(jì)太低。椐此，作為一般考慮，除了繁華熱鬧的場所，不妨大致把本底噪聲視為65~70dB（特殊情況除外）。照此推算，廣播覆蓋區(qū)的聲壓級宜在80~85dB以上。鑒于廣播揚(yáng)聲器通常是分散配置的，所以廣播覆蓋區(qū)的聲壓級可以近似地認(rèn)為是單個(gè)廣播揚(yáng)聲器的貢獻(xiàn)。根據(jù)有關(guān)的電聲學(xué)理論，揚(yáng)聲器覆蓋區(qū)的聲壓級SPL同揚(yáng)聲器的靈敏度級LM、饋給揚(yáng)聲器的電功率P、聽音點(diǎn)與揚(yáng)聲器的距離r等有如下關(guān)系：SPL=LM+10lgP–20lgrdB（1）天花喇叭的靈敏度級在88~93dB之間；額定功率為3~10W。以90dB/8W匡算，在離揚(yáng)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(xiàn)。在室內(nèi)，早期反射聲群和鄰近揚(yáng)聲器的貢獻(xiàn)可使聲壓級增加2~3dB左右。

藍(lán)牙背景音樂喇叭怎樣使用1.藍(lán)牙音箱喇叭充電。檢查一下藍(lán)牙音箱喇叭有沒有電，有些藍(lán)牙音箱是需要插上電才可以使用的，有些是可以先充好電然后在使用的。 </p> <p> 2.打開設(shè)置。在電腦桌面的左下角找到“開始”的位置，然后再眾多的菜單中，找到“設(shè)置”，點(diǎn)擊它。 </p> <p> 3.找到“藍(lán)牙”。點(diǎn)擊“設(shè)置”之后，我們就進(jìn)入了windows的設(shè)置界面，在設(shè)置界面里有很多的設(shè)置選項(xiàng)，我們找到“藍(lán)牙”這個(gè)選項(xiàng)，點(diǎn)擊它。 </p> <p> 4.開啟藍(lán)牙。進(jìn)入了藍(lán)牙的選項(xiàng)之后，在左側(cè)的菜單欄找到“藍(lán)牙和其他設(shè)備”，在右側(cè)彈出的菜單中，將藍(lán)牙開啟。 </p> <p> 5.搜索設(shè)備。如果你還沒有連過藍(lán)牙音箱，需要進(jìn)行搜索設(shè)備，點(diǎn)擊“添加藍(lán)牙或者其他設(shè)備”，再次點(diǎn)擊“藍(lán)牙”，等待藍(lán)牙音箱名字的出現(xiàn)，然后點(diǎn)擊... </p> <p> <br /> 東莞酒店背景音樂喇叭商家</p><p
