style="font-size:16px;">你頭戴耳機(jī)上的叫駐極體麥克風(fēng)，成本不超過(guò)一塊錢(qián)，但并不影響你和女神談人生聊理想。而專(zhuān)業(yè)麥克風(fēng)不但要能拾取到聲音，而且對(duì)音色有很高要求。錄音師追求好的麥克風(fēng)，和攝影師追求好的鏡頭差不多。</span> </p> <p> <span style="font-size:16px;">2、專(zhuān)業(yè)麥克風(fēng)的種類(lèi)有哪些？</span> </p> <p> <span style="font-size:16px;">動(dòng)圈麥克風(fēng)：非專(zhuān)業(yè)場(chǎng)合，例如KTV，見(jiàn)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(guò)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)，武漢無(wú)線手持話筒批發(fā)，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，武漢無(wú)線手持話筒批發(fā)，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(zhuān)業(yè)音頻接口或話放都帶有幻象電源供電，武漢無(wú)線手持話筒批發(fā)。</span>

style="font-size:16px;">說(shuō)起話筒，很多人可能馬上就會(huì)想到KTV唱歌時(shí)使用的話筒，或者是教師講課時(shí)老師手里拿著的無(wú)線話筒，又或者是平常在玩游戲時(shí)用到的耳機(jī)麥克風(fēng)。其實(shí)除了需要保證高音質(zhì)的專(zhuān)業(yè)人員，一般其他的人都不會(huì)對(duì)話筒有多么深刻的了解，更多的是根據(jù)價(jià)格來(lái)區(qū)分話筒的好壞。所以一般人對(duì)于麥克風(fēng)*的認(rèn)識(shí)可能是有線和無(wú)線，一種便宜一種貴。</span> </p> <p> <span style="font-size:16px;"> 一般來(lái)說(shuō)，普通的話筒比較便宜，專(zhuān)業(yè)的話筒比較貴。但*根本的區(qū)別是：普通話筒只要能拾到聲音聽(tīng)清楚就OK了，你的CS隊(duì)友不會(huì)在意你的聲音低頻是否渾厚高頻是否甜美，你不會(huì)在意老師講課的聲音是否有磁性，你QQ聊天時(shí)用的頭戴耳機(jī)上的駐極體話筒成本可能不會(huì)超過(guò)一塊錢(qián)，但并不影響你和MM談人生聊理想。而專(zhuān)業(yè)話筒不但要能拾取到聲音，而且要拾取的完整、清晰、對(duì)音色有很高的要求。所以錄音師追求好的話筒和攝影師追求好的相機(jī)鏡頭是一個(gè)道理。</span>

style="font-size:16px;">為助力行業(yè)復(fù)工，BBS推出了專(zhuān)為麥克風(fēng)設(shè)計(jì)的紫外線消毒一體機(jī)，受到行業(yè)內(nèi)人士的關(guān)注。安全，高效，智能是BBS麥克風(fēng)消毒機(jī)研發(fā)立項(xiàng)時(shí)的三大理念，本篇文章立足這三個(gè)方面，以科普的形式來(lái)給大家做一個(gè)產(chǎn)品深度解析。</span> </p> <p> <span style="font-size:16px;">紫外線殺菌消毒的原理，簡(jiǎn)單來(lái)說(shuō)就是利用電磁輻射對(duì)微生物(細(xì)菌、、芽孢等病原體)的核酸進(jìn)行破壞使其失活，達(dá)到殺菌消毒的效果。真正具有殺菌作用的是UVC紫外線，因?yàn)镃波段紫外線很易被生物體的DNA吸收，尤以253.7nm左右的紫外線。但是短波紫外線對(duì)人體的傷害很大，短時(shí)間照射即可灼傷皮膚，長(zhǎng)期或**度照射還會(huì)造成皮膚病。所以一款合格的麥克風(fēng)消毒機(jī)，首先要做到安全！</span><span

<p> <span style="font-size:16px;"> 1、裝上天線調(diào)到位置（天線與接收機(jī)平面保持垂直），把接收機(jī)一字排開(kāi)，天線在同一直線上，機(jī)與機(jī)之間保持15cm以上,這樣對(duì)于一兩百平方米的會(huì)議廳沒(méi)問(wèn)題。</span> </p> <p> <span style="font-size:16px;"> 2、增加一臺(tái)天線分配器再共用一對(duì)天線即可（注：每臺(tái)話筒都要同是U頻或V頻，因?yàn)轭l段不同天線是不同的，都是取1/2波長(zhǎng)）總結(jié)：發(fā)射功率30mw的射頻在無(wú)障礙物的情況下接收距離至少會(huì)在70m外，為什么會(huì)造成這種現(xiàn)象呢？因?yàn)楫?dāng)附近有金屬物時(shí)就會(huì)產(chǎn)生高頻反射，當(dāng)反射波和直射反向時(shí)，就會(huì)引起波全部抵消或局部抵消，從而會(huì)產(chǎn)生斷頻現(xiàn)象（接收機(jī)疊在一塊時(shí)多余的天線和接收機(jī)都成了金屬反射物）</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(jiàn)的娛樂(lè)無(wú)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(lái)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(guò)程，但是紅外線對(duì)頻對(duì)使用環(huán)境的依賴(lài)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
