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(gè)條件，就可達(dá)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(kuò)音音量的方法之一就是將話筒盡量靠近聲源拾音，同時(shí)話筒應(yīng)使用無指向性的。在這里明確一下，指向性話筒(尤其是銳指向性話筒)遠(yuǎn)距離聲源的拾音衰減很小，調(diào)整距離對(duì)提升擴(kuò)音音量和防止嘯叫的作用不大。擴(kuò)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(shí)際上可以提升擴(kuò)音的響度?？蛇m當(dāng)?shù)臏p小系統(tǒng)的總增益。若同時(shí)輔以指向性寬的近場(chǎng)音箱，話筒稍微離遠(yuǎn)點(diǎn)就能避免嘯叫。</span> </p> <p> <span style="font-size:16px;">對(duì)于揚(yáng)聲器的直接反饋聲場(chǎng)來說，就是話筒距揚(yáng)聲器越遠(yuǎn)越好，武漢無線手持話筒批發(fā)供應(yīng)，揚(yáng)聲器距聽眾越近越好。話筒應(yīng)放在揚(yáng)聲器輻射方向的背面，如果話筒有可能被拿著四處走動(dòng)，揚(yáng)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)，武漢無線手持話筒批發(fā)供應(yīng)，以及廳堂聲場(chǎng)的聲學(xué)諧振作用，武漢無線手持話筒批發(fā)供應(yīng)，使頻率響應(yīng)起伏很大。</span> </p> <span

<span style="font-size:16px;">當(dāng)智能化系統(tǒng)無孔不入的鉆入我們的生活，越來越多的智能化設(shè)備正在潛移默化的改變著我們的生活習(xí)慣。從不斷突破的技術(shù)創(chuàng)新到智能應(yīng)用的不斷升級(jí)，BBS麥克風(fēng)問世的每一款產(chǎn)品都匯聚了消費(fèi)者不同時(shí)期的使用需求。隨著BBS U-1500S的問世，娛樂麥克風(fēng)開啟了真正的智能時(shí)代，必將娛樂麥克風(fēng)領(lǐng)域的智能化**。</span> </p> <p> <span style="font-size:16px;">智能一詞在辭海中的解釋為“人的智慧和行動(dòng)能力”，延伸到產(chǎn)品上的定義就是智慧化的操控，也就是簡(jiǎn)化操控、一步到位。常見的娛樂無線麥克風(fēng)系統(tǒng)在安裝時(shí)，需要手動(dòng)調(diào)節(jié)接收機(jī)和話筒的發(fā)射頻率，然后才能正常工作，這種安裝方式十分繁瑣，而且也對(duì)系統(tǒng)后期的維護(hù)帶來了諸多不便。紅外對(duì)頻方式雖然解決了手動(dòng)調(diào)頻的繁瑣過程，但是紅外線對(duì)頻對(duì)使用環(huán)境的依賴性較大。比如，對(duì)使用場(chǎng)合的燈光、持握方向等都有一定要求。簡(jiǎn)化麥克風(fēng)的調(diào)試操控，是麥克風(fēng)智能化邁出的第一步，BBS研發(fā)工程師以此為基礎(chǔ)，重新定義了智能麥克風(fēng)：省時(shí)、省力、省心的麥克風(fēng)。</span><span

style="font-size:16px;">2、專業(yè)麥克風(fēng)的種類有哪些？</span> </p> <p> <span style="font-size:16px;">動(dòng)圈麥克風(fēng)：非專業(yè)場(chǎng)合，例如KTV，見到多的就是動(dòng)圈麥克風(fēng)。它的原理是麥克風(fēng)頭里的振膜帶動(dòng)線圈振動(dòng)，切割磁力線產(chǎn)生電信號(hào)，通過麥克風(fēng)線傳遞給下一級(jí)設(shè)備。它的優(yōu)點(diǎn)是結(jié)構(gòu)簡(jiǎn)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> <span style="font-size:16px;">電容麥克風(fēng)：錄音領(lǐng)域應(yīng)用的多的麥克風(fēng)。原理是用一張極薄的金屬振膜作為電容的一級(jí)，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(huì)造成電容的變化，從而形成電信號(hào)。由于振膜非常薄，微小的聲音也能使其振動(dòng)，所以電容麥克風(fēng)非常靈敏。注意電容麥克風(fēng)需要一個(gè)極化電壓，微弱的信號(hào)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>

style="font-size:16px;">BBS麥克風(fēng)智能消毒機(jī)在保證產(chǎn)品安全的同時(shí)，又是如何做到高效的呢？優(yōu)先采用了真正的行業(yè)標(biāo)準(zhǔn)4W低壓汞燈作為紫外線光源，在距離30cm處測(cè)試，254nm輻射照度值≥90uW/cm2，與采用UV-LED固態(tài)光源的產(chǎn)品相比，輻射效率更高；獨(dú)特的內(nèi)部鏡面反射設(shè)計(jì)，保證紫外線無死角照射，上下鏡面反射紫外光線，能讓麥克風(fēng)無死角消毒；除此之外，紫外燈開關(guān)壽命≥50000次，額定壽命≥5000小時(shí)，保證消毒機(jī)能夠長效穩(wěn)定工作。</span>
