的技術(shù)**并不多，除了《國(guó)王的演講》中的 “碳話筒” 已淘汰，后來(lái)的鋁帶話筒、動(dòng)圈話筒、和電容話筒都是目前比較主流的。</span> </p> <p> <span style="font-size:16px;">鋁帶話筒 - Ribbon Microphone</span> </p> <p> <span style="font-size:16px;">它與電容話筒都是上世紀(jì)30年代興起的技術(shù)，歐洲人民偏好電容話筒，美國(guó)人民偏好鋁帶話筒，形成了一種行業(yè)習(xí)慣直到，可謂美國(guó)的 “國(guó)民話筒”，武漢無(wú)線會(huì)議話筒品牌。聲音特點(diǎn)是肥暖（低頻出色）、銜接平滑、瞬態(tài)較慢、高頻偏少，簡(jiǎn)而言之是 “舒服、不刺激”，輕爵士和慢歌御用，有時(shí)也用于替代動(dòng)圈話筒錄制大聲壓（例如吉他箱）或高頻太亮（例如小號(hào)）的樂(lè)器。</span> </p> <p> <span style="font-size:16px;">盡管在八九十年代逐漸被電容話筒取代，但2000年以后鋁帶技術(shù)有重大進(jìn)展，電容話筒反而停滯不前。到2015年前后，武漢無(wú)線會(huì)議話筒品牌，新式鋁帶話筒已能達(dá)到電容話筒的靈敏度與頻率響應(yīng)，同時(shí)依然保持了以前的音色特點(diǎn)，價(jià)格也大幅下降，武漢無(wú)線會(huì)議話筒品牌，成為音樂(lè)人的新選擇。</span>

style="font-size:16px;">動(dòng)圈話筒：非專業(yè)場(chǎng)合，例如KTV，見(jiàn)到多的就是動(dòng)圈話筒。它結(jié)構(gòu)簡(jiǎn)單、結(jié)實(shí)耐用、價(jià)格便宜；但是靈敏度不夠，頻率響應(yīng)不足，音色不夠細(xì)膩。</span> </p> <p> <br /> </p> <p> <span style="font-size:16px;">動(dòng)圈話筒</span> </p> <p> <span style="font-size:16px;">電容話筒：錄音領(lǐng)域應(yīng)用的多的話筒。電容話筒的靈敏度高，頻率響應(yīng)好。但價(jià)格相對(duì)比動(dòng)圈話筒高，而且比較嬌貴，務(wù)必小心使用。需要幻象電源供電才能正常工作。</span> </p> <p> <span style="font-size:16px;">電容話筒</span> </p> <p> <span style="font-size:16px;">電容話筒有大振膜和小振膜。那要怎么區(qū)分？振膜直徑大于或者等于3/4英寸的話筒稱做大振膜話筒。經(jīng)常用于人聲錄音，因?yàn)樗鼈兡軌驗(yàn)槁曇籼砑又C波，讓聲音聽(tīng)起來(lái)更加平滑。</span> </p> <p> <span style="font-size:16px;">大振膜</span> </p> <p> <span style="font-size:16px;">凡是振膜直徑小于5/8英寸的話筒均屬于小振膜話筒。相比大振膜，小振膜所接受到的聲源信號(hào)面積小，聲音就比較亮，堅(jiān)的感覺(jué)，具備平坦的頻率響應(yīng)，聲音更加自然，因此，普遍用于樂(lè)器錄音。</span> </p> <p> <span style="font-size:16px;">小振膜</span> </p> <p> <span style="font-size:16px;">另外近年來(lái)還出現(xiàn)"中振膜"話筒。一般來(lái)說(shuō)振膜直徑在5/8英寸到3/4英寸之間的話筒均屬于中振膜話筒。比較擅長(zhǎng)捕捉瞬時(shí)信號(hào)和高頻信號(hào)，且其聲音效果相對(duì)比較圓潤(rùn)飽滿，帶有大振膜話筒的溫暖質(zhì)感。</span> </p> <p> <br />

</p> <p> <span style="font-size:16px;">1.電池沒(méi)電的可能性大，把電池及時(shí)換新的</span> </p> <p> <span style="font-size:16px;">2.其他電子產(chǎn)品的信號(hào)干擾，例如手機(jī)，路由器，電視等</span> </p> <p> <span

</p> <p> <span style="font-size:16px;">這一距離確定之后，在演唱時(shí)還要有些調(diào)整。這是因?yàn)樵诓煌囊魠^(qū)，不同的力度條件下，人的音量有著很大的差別，較弱的低音與較強(qiáng)的高音可相差幾十倍。</span> </p> <p> <br />
