style="font-size:16px;">專業(yè)話筒如何更好為人聲拾音</span> </p> <p> <br /> </p> <p> <span style="font-size:16px;">消除反饋嘯叫要從產(chǎn)生反饋嘯叫的必要條件入手，只要能破壞其中一個條件，就可達到目的。</span> </p> <p> <span style="font-size:16px;">調(diào)整距離法</span> </p> <p> <span style="font-size:16px;">既避免嘯叫又能提升擴音音量的方法之一就是將話筒盡量靠近聲源拾音，同時話筒應(yīng)使用無指向性的。在這里明確一下，武漢會議話筒，指向性話筒(尤其是銳指向性話筒)遠距離聲源的拾音衰減很小，調(diào)整距離對提升擴音音量和防止嘯叫的作用不大。擴聲系統(tǒng)是否容易嘯叫，與話筒的靈敏度沒有直接關(guān)系。只不過高靈敏度的話筒都是銳指向性的，容易產(chǎn)生嘯叫罷了?？s短發(fā)聲設(shè)備與聽眾的距離，實際上可以提升擴音的響度?？蛇m當(dāng)?shù)臏p小系統(tǒng)的總增益。若同時輔以指向性寬的近場音箱，武漢會議話筒，話筒稍微離遠點就能避免嘯叫。</span> </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。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。</span> </p> <p> <span style="font-size:16px;">頻率均衡法(寬帶陷波法)</span> </p> <p> <span style="font-size:16px;">由于話筒拾音和發(fā)聲設(shè)備的頻率曲線不是理想平坦的直線(特別是一些質(zhì)量比較差的放音設(shè)備)，以及廳堂聲場的聲學(xué)諧振作用，使頻率響應(yīng)起伏很大。</span> </p> <span

style="font-size:16px;">在一百多平方的會議室里同時使用三套話筒,都是雙通道的,會議沒開始時試音基本正常,可是客人坐滿后,在十米外就會斷頻。當(dāng)時用戶是三臺疊在一起的,三套話筒頻點都是錯開互不干擾的,而且都已經(jīng)裝上天線，天線交不交叉不知道。為什么會造成這種情況呢？是不是人多造成的影響？這個是有但是影響不大（因為人多物多會吸收一定的電波），主要的就是他直接把接收機疊在一塊。解決方案有兩個，</span> <p> <span style="font-size:16px;"> 1、裝上天線調(diào)到位置（天線與接收機平面保持垂直），把接收機一字排開，天線在同一直線上，機與機之間保持15cm以上,這樣對于一兩百平方米的會議廳沒問題。</span> </p> <p> <span style="font-size:16px;"> 2、增加一臺天線分配器再共用一對天線即可（注：每臺話筒都要同是U頻或V頻，因為頻段不同天線是不同的，都是取1/2波長）總結(jié)：發(fā)射功率30mw的射頻在無障礙物的情況下接收距離至少會在70m外，為什么會造成這種現(xiàn)象呢？因為當(dāng)附近有金屬物時就會產(chǎn)生高頻反射，當(dāng)反射波和直射反向時，就會引起波全部抵消或局部抵消，從而會產(chǎn)生斷頻現(xiàn)象（接收機疊在一塊時多余的天線和接收機都成了金屬反射物）</span>

style="max-width: 640px; max-height: 320px;" alt="武漢會議話筒,話筒" src="https://tyunfile.71360.com/UploadFile/jzwhywxtjc/637378590804804688/4203224.png"></div><p> <span style="font-size:16px;">如何正確調(diào)試話筒錄出好聲音？</span> </p> <p> <br /> </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><p> <span style="font-size:16px;">無線話筒的選擇</span> </p> <p> <br /> </p> <p> <span style="font-size:16px;">很多家庭消費者會選擇在閑暇時，在家唱唱歌，配備一套質(zhì)量的無線話筒，加上點歌機和家庭音響，也可享受歌星演出的感覺。下面我們主要談?wù)劗?dāng)中的無線話筒怎樣選擇。</span> </p> <p> <span style="font-size:16px;">在一般的家庭音響里，配備專業(yè)KTV音響的畢竟是少數(shù)，大部分都是AV功放和環(huán)繞音響，因為大家大部分時間都是用來看家庭影碟和播放電影的設(shè)備。在這種情況下，選擇一個功能簡單，方便使用的無線話筒尤為重要。音質(zhì)方面為了配合家庭音響的特性，中高音要通透，低頻略少，否則老是出現(xiàn)嗡嗡的低頻共振會很難受。</span> </p> <p> <span style="font-size:16px;">本主推薦的適合家庭使用的無線話筒，是現(xiàn)在在海外市場上比較受歡迎的固定頻點UHF無線話筒，就是只有單獨的固定好的傳輸頻率，不可調(diào)頻的，是小型機子，就是我們常說的機仔，半U規(guī)格的。這種機型方便易用，裝上電池，接好線，馬上可以用。因為在家庭環(huán)境，無線干擾一般不多，用單頻點的固U足矣。而且這種機仔主要是出口的規(guī)格，中高頻調(diào)整得比較突出，輕輕出聲，立馬就身臨其境，沒錯，就是那種"好入咪"的感覺，無需很用力的去唱，就可以獲得滿意的聲壓。當(dāng)然選購的時候要注意測試是否有嚴重的高頻嘯叫，還要注意一下有沒有明顯失真就可以了。</span>
