style="font-size:16px;">一般來講，動(dòng)圈話筒的音頭比較大。KTV和舞臺(tái)話筒都是動(dòng)圈話筒，但是用的材料不一樣。</span> </p> <p> <span style="font-size:16px;">優(yōu)點(diǎn)：音質(zhì)加了效果，聲音渾厚，飽滿</span> </p> <p> <span style="font-size:16px;">缺點(diǎn)：動(dòng)圈話筒是近講話筒，靈敏度不高，聲音小，離得太遠(yuǎn)是不行的。</span> </p> <p> <span style="font-size:16px;">電容話筒的音頭比較小。錄音，會(huì)議場(chǎng)合都是電容話筒。</span> </p> <p> <span

<span 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(hào)。然后問是不是再加長(zhǎng)天線，或者是加多兩個(gè)天線就行。</span> </p> <p> <span style="font-size:16px;">無線話筒的信號(hào)不能靠加天線來解決，雖然天線越多信號(hào)越強(qiáng)是對(duì)的。但是天線要加多少是根據(jù)接收機(jī)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(jìn)的了，因?yàn)閺S家基本上已經(jīng)把它設(shè)計(jì)的潛力挖盡了</span> </p> <p> <span style="font-size:16px;">無線話筒的信號(hào)如何增加呢？</span> </p> <p> <span style="font-size:16px;">提供以下幾個(gè)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(zhǔn)，就是降低接收的門檻，同時(shí)也就更容易受到干擾</span> </p> <p> <span style="font-size:16px;">3.增加一臺(tái)天線放大器。</span> </p> <p> <span style="font-size:16px;">4.盡量減少信號(hào)障礙物</span> </p> <span style="font-size:16px;"></span> <p> <br />

style="font-size:16px;">現(xiàn)場(chǎng)可以和音響工程師或AV技術(shù)人員交流溝通，找出適合自己使用的話筒類型。如果對(duì)特定類型的話筒更得心應(yīng)手，可以要求提供，大多數(shù)音響工程師都很欣賞那些充分考慮聲音效果的演講者。</span> </p> <p> <span style="font-size:16px;">3.在演講場(chǎng)地走動(dòng)體驗(yàn)</span> </p> <p> <span style="font-size:16px;">攜話筒在房間中走動(dòng)，如果使用的是無線手持或領(lǐng)夾式話筒，無論身在何處，都要確保音質(zhì)，保證自己的動(dòng)作不會(huì)被話筒拾?。ɡ绾粑暬蛞路纳成陈暎?，同時(shí)也不要忽視了后排的聽眾。</span>
