style="font-size:16px;">為助力行業(yè)復(fù)工，BBS推出了專為麥克風(fēng)設(shè)計(jì)的紫外線消毒一體機(jī)，受到行業(yè)內(nèi)人士的關(guān)注。安全，高效，智能是BBS麥克風(fēng)消毒機(jī)研發(fā)立項(xiàng)時的三大理念，本篇文章立足這三個方面，以科普的形式來給大家做一個產(chǎn)品深度解析。</span> </p> <p> <span style="font-size:16px;">紫外線殺菌消毒的原理，簡單來說就是利用電磁輻射對微生物(細(xì)菌、、芽孢等病原體)的核酸進(jìn)行破壞使其失活，達(dá)到殺菌消毒的效果。真正具有殺菌作用的是UVC紫外線，因?yàn)镃波段紫外線很易被生物體的DNA吸收，尤以253.7nm左右的紫外線。但是短波紫外線對人體的傷害很大，短時間照射即可灼傷皮膚，長期或**度照射還會造成皮膚病，武漢會議話筒批發(fā)商，武漢會議話筒批發(fā)商。所以一款合格的麥克風(fēng)消毒機(jī)，首先要做到安全，武漢會議話筒批發(fā)商！</span><span

style="font-size:16px;">靈敏度是什么？靈敏度是表示話筒聲電轉(zhuǎn)換效率的重要指標(biāo)。靈敏度高也就表示其可以提供較高的輸入電平，可以提高信噪比，但是靈敏度太高會容易產(chǎn)生過載失真。說白了就是靈敏度越高聲電轉(zhuǎn)換電平越大。通常電容式話筒靈敏度比動圈式高10倍左右。 </span> </p> <p> <span style="font-size:16px;">例如：靈敏度：18 mV/Pa < 25 mV/Pa ；靈敏度：-32 dB < -40 dB 2、什么是頻率響應(yīng)？麥克風(fēng)在恒定聲壓和規(guī)定入射角聲波作用下，各頻率聲波信號的開路輸出電壓與規(guī)定頻率麥克風(fēng)開路輸出電壓之比，稱為麥克風(fēng)的頻率響應(yīng)，用分貝（db）表示。理想的頻率響應(yīng)曲線為一條水平線，輸出信號能直實(shí)呈現(xiàn)原始聲音的特性，但這種理想情況不容易實(shí)現(xiàn)。</span> </p><p> <span style="font-size:16px;">為什么專業(yè)麥克風(fēng)在歌手大賽中非常重要？</span> </p> <p> <br /> </p> <p> <span style="font-size:16px;">目前，在很多地方臺舉辦的歌手大賽中，出現(xiàn)一種這樣的現(xiàn)象：音樂會的音響燈光效果都不錯，但唯獨(dú)歌手的聲音音質(zhì)不好或者說聲音品質(zhì)比較次，而這些歌手在錄音棚里錄音時的音質(zhì)又確實(shí)不錯。這原因到底出在哪呢?筆者經(jīng)過細(xì)心觀察研究發(fā)現(xiàn)問題就出在歌手們使用的麥克風(fēng)上。筆者輔導(dǎo)的學(xué)生樂隊(duì)曾經(jīng)參加過三場廣州市區(qū)級的流行歌曲比賽和音樂演出，音響設(shè)備都不錯，但歌手使用的麥克風(fēng)確實(shí)太差，大概不超過5000元一套的無線麥克風(fēng)組合，筆者為了把音樂比賽視頻錄像發(fā)往微信網(wǎng)上，特地采用了專業(yè)錄音機(jī)進(jìn)行內(nèi)錄，結(jié)果錄出來的效果都發(fā)現(xiàn)人聲部分音質(zhì)太差，究其原因，原來使用的無線麥克風(fēng)達(dá)不到音樂會的技術(shù)要求。</span> </p> <p> <span style="font-size:16px;"> </span> </p> <p> <span style="font-size:16px;">試想一下：一場大都市區(qū)級的歌手大賽，樂器燈光設(shè)備都比較，電鋼琴、合成器、電子鼓等都是進(jìn)口的，價值不菲，然而歌手麥克風(fēng)卻是不超過6000元一套的無線麥克風(fēng)系列，真的不可思議。這其實(shí)是音樂理念的問題，舍得花好幾萬塊錢去購置電鋼琴、合成器及音響，卻不舍得買一、兩萬購置歌唱用的無線麥克風(fēng)，如果是有線麥就只需要1000至2000元就可以買到的國際上標(biāo)配麥，真的不可思議!</span>

</p> <p> <br /> </p> <p> <span style="font-size:16px;">有個河南的朋友問我無線話筒一般是什么頻率的。</span> </p> <p> <span style="font-size:16px;">無線話筒是什么頻率跟你使用哪個頻段的有關(guān)。</span> </p> <p> <span style="font-size:16px;">如果你的是VHF無線話筒，那么話筒的頻率是在170-270Mhz這個范圍。</span> </p> <p> <span style="font-size:16px;">如果你的是UHF無線話筒，那么話筒的頻率是在400-900Mhz這個范圍。</span> </p> <p> <span style="font-size:16px;">VHF無線話筒是比較低檔次的話筒，比較容易斷頻。因?yàn)槭褂肰HF頻率的產(chǎn)品太多了，容易受到干擾。</span> </p> <p> <span style="font-size:16px;">UHF無線話筒算是中的話筒，因?yàn)槭歉哳l段，受到的干擾比較少。使用起來更加穩(wěn)定。</span> </p> <p> <span style="font-size:16px;">但是音質(zhì)的話，不是說UHF無線話筒的音質(zhì)就一定比VHF的好。</span> </p> <p> <span
