</p> <p> <span style="font-size:16px;">對于揚聲器的直接反饋聲場來說，就是話筒距揚聲器越遠越好，揚聲器距聽眾越近越好，武漢BBS專業(yè)娛樂話筒品牌。話筒應(yīng)放在揚聲器輻射方向的背面，如果話筒有可能被拿著四處走動，揚聲器應(yīng)放在話筒無法靠得很近的地方，武漢BBS專業(yè)娛樂話筒品牌。</span> </p> <p> <span

style="font-size:16px;">話筒話筒也叫傳聲器，工作原理是當(dāng)傳聲器接受聲波時，聲波產(chǎn)生的力量作用在振膜上，引起振膜振動，帶動音圈作相應(yīng)振動，音圈在磁鋼中運動，產(chǎn)生電動勢，聲音信號轉(zhuǎn)變成電信號。</span> </p> <p> <span style="font-size:16px;">錄音室常見的錄音話筒分為動圈話筒和電容話筒兩種。</span> </p> <p> <span style="font-size:16px;">電容話筒的特點是非常靈敏，頻率響應(yīng)比較寬廣，能夠捕捉到更多聲音細節(jié)，在錄音棚中使用率較高，對錄音環(huán)境的要求也比較高。電容話筒非常嬌貴，怕摔怕受潮，不錄音的時候要放到防潮柜儲存。</span> </p> <span style="font-size:16px;">動圈話筒的特點，是對環(huán)境適應(yīng)能力強。動圈話筒構(gòu)造相對簡單，經(jīng)濟耐用，能承受極高的聲壓，且?guī)缀醪皇軜O端溫度或濕度的影響。</span> <p> <br /> </p> <p> <br /> </p> <p> <span style="font-size:16px;">從聲學(xué)性能比較，一般來講，電容話筒在靈敏度和頻率響應(yīng)方面要優(yōu)于動圈話筒。這跟電容話筒需要先將聲音信號轉(zhuǎn)換成電流的工作原理有關(guān)。通常電容話筒的振膜都非常薄，很容易受到聲壓影響而發(fā)生震動，從而引起振膜與振膜艙后背板之間電壓的相應(yīng)改變。</span> </p> <p> <span style="font-size:16px;">一般的入門級聲卡，話放能力有限，對于動圈話筒的支持并不好，常見的情況就是推力不夠，所以我還是建議用電容話筒錄音。</span> </p> <span style="font-size:16px;"></span> <p> <br /> </p><h1> <span style="font-size:16px;">演出話筒的音質(zhì)一定比KTV話筒的音質(zhì)好嗎</span> </h1> <p> <br /> </p> <p> <span style="font-size:16px;">有很多客戶問我演出話筒的音質(zhì)是不是一定比KTV話筒的音質(zhì)好？</span> </p> <p> <span style="font-size:16px;">答案是：不一定。</span> </p> <p> <span style="font-size:16px;">有這種想法其實是心理暗示。因為演出的話筒比較貴，KTV話筒比較便宜些。</span> </p> <p> <span style="font-size:16px;">大部分人都是覺得越貴越好。</span> </p> <p> <span style="font-size:16px;">其實不是這樣的哈。</span> </p> <p> <span style="font-size:16px;">演出話筒是高音的，適合開闊的環(huán)境用。如果在家里十幾平方米的地方用，很容易發(fā)生嘯叫的。</span> </p> <p> <span style="font-size:16px;">這是因為空間太小，聲音反射比較嚴重。音頭同時接收你說話的聲音和被墻壁反射回來的聲音。</span> </p> <p> <span style="font-size:16px;">KTV話筒是低音的，適合室內(nèi)的環(huán)境使用。一般來講，室內(nèi)比較適合。</span> </p> <p> <span style="font-size:16px;">KTV話筒用在戶外比較開闊的地方，聲音會有點小，不過要求不是很高的話也是適用的。</span> </p> <p> <span style="font-size:16px;">無論是KTV話筒還是演出話筒都是帶點效果的。</span> </p> <p> <span style="font-size:16px;">大家要記住，不同類型的無線話筒要用在不同地方才能發(fā)揮它的效果。</span> </p> <p> <span style="font-size:16px;">貴的也不一定適合你，好用就行哈。</span> </p> <span style="font-size:16px;"></span> <p> <br />

style="font-size:16px;">近有一些客戶打電話來工廠問如何增加無線話筒的信號。然后問是不是再加長天線，或者是加多兩個天線就行。</span> </p> <p> <span style="font-size:16px;">無線話筒的信號不能靠加天線來解決，雖然天線越多信號越強是對的。但是天線要加多少是根據(jù)接收機里面的電路板來匹配的。</span> </p> <p> <span style="font-size:16px;">無線話筒一般很難再靠加天線等辦法改進的了，因為廠家基本上已經(jīng)把它設(shè)計的潛力挖盡了</span> </p> <p> <span style="font-size:16px;">無線話筒的信號如何增加呢？</span> </p> <p> <span style="font-size:16px;">提供以下幾個方法：</span> </p> <p> <span style="font-size:16px;">1.增加話筒的發(fā)射功率</span> </p> <p> <span style="font-size:16px;">2.降低接收的靜音位準，就是降低接收的門檻，同時也就更容易受到干擾</span> </p> <p> <span style="font-size:16px;">3.增加一臺天線放大器。</span> </p> <p> <span style="font-size:16px;">4.盡量減少信號障礙物</span> </p> <span style="font-size:16px;"></span> <p> <br />

style="font-size:16px;">BBSU-1500S應(yīng)用了型的防干擾技術(shù)——數(shù)字導(dǎo)頻技術(shù)，有效屏蔽雜波干擾，解決串頻問題。和發(fā)射器自動對頻時，由麥克風(fēng)里的芯片將一組全新且的身份ID碼發(fā)送到麥克風(fēng)芯片中，修改麥克風(fēng)發(fā)射頻率的同時，還同步了身份ID碼并鎖定，麥克風(fēng)依靠這的ID碼作為信號識別，其它頻率電波就無法產(chǎn)生干擾，就算是相同頻率電波都無法干擾。在實際使用中，特別是在大型娛樂KTV包房的工程安裝中，數(shù)字導(dǎo)頻技術(shù)起到了非常大的優(yōu)勢。因為房間數(shù)量多，需要使用很多套無線話筒，在這個環(huán)境中頻率分配得不好就直接影響正常使用，沒有數(shù)字導(dǎo)頻技術(shù)之前， KTV工程安裝時需要經(jīng)過精密的計算才能規(guī)劃出完美的頻率分布，這要花費大量的時間。時間就是金錢，節(jié)省時間等于節(jié)省成本，增加收入。BBS U-1500S使用了數(shù)字導(dǎo)頻技術(shù)，不但能極大減少安裝調(diào)試時間，同時在正常使用中還能避免外界雜波的干擾，帶來良好的使用體驗。</span>
