</p> <p> <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。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，武漢無線手持話筒品牌.降低接收的靜音位準，武漢無線手持話筒品牌，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，武漢無線手持話筒品牌.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 /> 會議話筒哪個牌子好，武漢音王系統(tǒng)集成有限公司，專業(yè)為您服務(wù)！武漢無線手持話筒品牌</p><div style="width:100%;text-align:

style="font-size:16px;">話筒麥克風指向性是什么意思？有什么作用，怎么看？</span> </p> <p> <br /> </p> <p> <span style="font-size:16px;">了解基本的指向性使用原則有助于在每一次錄音中都得到較好的結(jié)果，指向性決定一支話筒在不同角度的靈敏度。也就是說，決定了在不同方向，有多少信號被拾取。</span> </p> <p> <span style="font-size:16px;">通過選擇正確的模式，您可以避免不需要的聲源流入信號，調(diào)整干聲和室內(nèi)聲音之間的混音，或改變頻率響應(yīng)，并影響鄰近效果。</span> </p> <p> <span style="font-size:16px;">如何讀取指向圖</span> </p> <p> <span style="font-size:16px;">首要的，你要能正確地閱讀指向性圖表。它包括了影響你錄音的所有必要信息。</span> </p> <p> <span style="font-size:16px;">試著想象話筒在一個360度寬敞的場地里，0度是話筒的正面，這個角度的話筒具有較大的靈敏度。指向性的圓圈的涵蓋了一些小圈，每一個圈衰減5dB。</span> </p> <p> <span style="font-size:16px;">分貝是(dB)是對比兩個數(shù)值的的對立單位。如果一支具有心型指向參數(shù)的話筒具有25dB，那么，敏感度較高的部分(0°)和敏感度較低的部分(180°)呈對比。</span> </p> <p> <span style="font-size:16px;">對聲壓，當前和電壓+6 dB信號放大了兩倍，+20 dB會導(dǎo)致10倍信號。典型的心型指向的離軸反應(yīng)是-20 dB。</span> </p> <span style="font-size:16px;"></span> <p> <br /> 武漢無線手持話筒品牌bbs話筒，武漢音王系統(tǒng)集成有限公司，專業(yè)為您服務(wù)！</p><div style="width:100%;text-align:

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30年代興起的技術(shù)，歐洲人民偏好電容話筒，美國人民偏好鋁帶話筒，形成了一種行業(yè)習慣直到，可謂美國的 “國民話筒”。聲音特點是肥暖（低頻出色）、銜接平滑、瞬態(tài)較慢、高頻偏少，簡而言之是 “舒服、不刺激”，輕爵士和慢歌御用，有時也用于替代動圈話筒錄制大聲壓（例如吉他箱）或高頻太亮（例如小號）的樂器。</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)有重大進展，電容話筒反而停滯不前。到2015年前后，新式鋁帶話筒已能達到電容話筒的靈敏度與頻率響應(yīng)，同時依然保持了以前的音色特點，價格也大幅下降，成為音樂人的新選擇。</span> </p> <span style="font-size:16px;"></span>

<br /> </p> <p> <span style="font-size:16px;">以手掌抓著麥克風頭會破壞麥克風音質(zhì)的不良姿態(tài)，即使是名貴的麥克風也一樣，原因是掌握網(wǎng)頂頭等于隔絕音頭改變氣室的諧振頻率，導(dǎo)致麥克風的正面頻率響應(yīng)及指向性劣化，而且因手掌的聚音效應(yīng)會造成某一段頻率的諧振而增強產(chǎn)生回授聲。</span> </p> <p> <br /> </p>
