style="font-size:16px;">唱歌話筒大科普——唱歌麥克風(fēng)選購的小技巧</span> </p> <p> <br /> </p> <p> <span style="font-size:16px;">1、普通話筒和專業(yè)話筒有什么區(qū)別？</span> </p> <p> <br /> </p> <p> <span style="font-size:16px;">相當(dāng)于卡片相機(jī)與單反相機(jī)的區(qū)別。用QQ聊天把妹時(shí)，你頭戴耳機(jī)上的叫駐極體話筒，成本不超過一塊錢，但并不影響你和MM談人生聊理想。而專業(yè)話筒不但要能拾取到聲音，而且對音色有很高要求。錄音師追求好的話筒，和攝影師追求好的鏡頭差不多。</span> </p> <span style="font-size:16px;"></span><span style="font-size:16px;">2、專業(yè)話筒的種類有哪些？</span><span style="font-size:16px;"></span> <p> <br /> </p> <p> <br /> </p> <p> <span style="font-size:16px;">動(dòng)圈話筒：非專業(yè)場合，例如KTV，見到多的就是動(dòng)圈話筒。它的原理是話筒頭里的振膜帶動(dòng)線圈振動(dòng)，切割磁力線產(chǎn)生電信號，通過話筒線傳遞給下一級設(shè)備。它的優(yōu)點(diǎn)是結(jié)構(gòu)簡單、結(jié)實(shí)耐用、價(jià)格便宜；缺點(diǎn)是靈敏度不夠，高頻響應(yīng)不足，音色不夠細(xì)膩。</span> </p> <p> <br /> </p> <p> <span style="font-size:16px;">電容話筒：錄音領(lǐng)域應(yīng)用的多的話筒。原理是用一張極薄的金屬振膜作為電容的一級，另一個(gè)距離很近的金屬背板（零點(diǎn)幾毫米）作為另一極，振膜的振動(dòng)會造成電容的變化，從而形成電信號。由于振膜非常薄，微小的聲音也能使其振動(dòng)，所以電容話筒非常靈敏。注意電容話筒需要一個(gè)極化電壓，微弱的信號也需要一個(gè)預(yù)放大，所以專業(yè)音頻接口或話放都帶有幻象電源供電。</span> </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p><p> <span style="font-size:16px;">話筒的一大堆技術(shù)指標(biāo)都什么？</span> </p> <p> <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(dòng)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>

style="font-size:16px;">在現(xiàn)代大型演明和家庭“卡拉OK”中，話筒既是演員和歌唱愛好者的“聲音媒介”，同時(shí)也是他們表演中的一個(gè)道具。舞臺演唱中的話筒主要分為：立式話筒、手持有線話筒、手持無線話筒和小扣麥四種。</span> </p> <p> <br /> </p> <p> <span style="font-size:16px;">1.立式話筒在舞臺上的位置通常較穩(wěn)定，其話簡架與話簡有時(shí)可脫離。根據(jù)演員的需要，演員有時(shí)候兩手放開，配合歌曲情緒做自由動(dòng)作；有時(shí)也可將話筒單獨(dú)拿下來作必要的動(dòng)作變化。使用這種話簡的特點(diǎn)是演員不能離話筒太遠(yuǎn)，其表演區(qū)域相對較小，適合于美聲、戲劇唱法的作品。</span> </p> <p> <span style="font-size:16px;">2.手持有線話筒是演唱中使用普遍的一種，其道具性尤為突出，演員可一只手持話筒，左右交替，靈活白如。由于演員可以隨時(shí)改變話簡和山形的距離、方向、角度，所以演唱的音量、音色變化可以得到更豐富的對比。</span> </p> <p> <span style="font-size:16px;">在演唱中，演員如果想保持力度或做情緒及音量上的漸強(qiáng)或漸弱，除了演唱本身的技巧外，的就是調(diào)整話筒與自已演唱的遠(yuǎn)近距離及角度，此外，在使用手持有線話簡時(shí)，演員在動(dòng)作變化、表演區(qū)域變化時(shí)述應(yīng)注意處理好話簡線，以免纏腿或線本身“纏死”等現(xiàn)象的發(fā)生。這類話筒適用于民族和通俗唱法。</span>

style="font-size:16px;"> </span><span style="font-size:16px;">說起話筒，很多人可能馬上就會想到KTV唱歌時(shí)使用的話筒，或者是教師講課時(shí)老師手里拿著的無線話筒，又或者是平常在玩游戲時(shí)用到的耳機(jī)麥克風(fēng)。其實(shí)除了需要保證高音質(zhì)的專業(yè)人員，一般其他的人都不會對話筒有多么深刻的了解，更多的是根據(jù)價(jià)格來區(qū)分話筒的好壞。所以一般人對于麥克風(fēng)*的認(rèn)識可能是有線和無線，一種便宜一種貴。</span> </p> <p> <span style="font-size:16px;"> 一般來說，普通的話筒比較便宜，專業(yè)的話筒比較貴。但*根本的區(qū)別是：普通話筒只要能拾到聲音聽清楚就OK了，你的CS隊(duì)友不會在意你的聲音低頻是否渾厚高頻是否甜美，你不會在意老師講課的聲音是否有磁性，你QQ聊天時(shí)用的頭戴耳機(jī)上的駐極體話筒成本可能不會超過一塊錢，但并不影響你和MM談人生聊理想。而專業(yè)話筒不但要能拾取到聲音，而且要拾取的完整、清晰、對音色有很高的要求。所以錄音師追求好的話筒和攝影師追求好的相機(jī)鏡頭是一個(gè)道理。</span>
