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，武漢會(huì)議話筒哪個(gè)好。若同時(shí)輔以指向性寬的近場(chǎng)音箱，武漢會(huì)議話筒哪個(gè)好，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，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，武漢會(huì)議話筒哪個(gè)好。</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(chǎng)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;"></span> <p> <br />

<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，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)議廳沒問題。</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）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(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;">答案是：不一定。</span> </p> <p> <span style="font-size:16px;">有這種想法其實(shí)是心理暗示。因?yàn)檠莩龅脑捦脖容^貴，KTV話筒比較便宜些。</span> </p> <p> <span style="font-size:16px;">大部分人都是覺得越貴越好。</span> </p> <p> <span style="font-size:16px;">其實(shí)不是這樣的哈。</span> </p> <p> <span style="font-size:16px;">演出話筒是高音的，適合開闊的環(huán)境用。如果在家里十幾平方米的地方用，很容易發(fā)生嘯叫的。</span> </p> <p> <span style="font-size:16px;">這是因?yàn)榭臻g太小，聲音反射比較嚴(yán)重。音頭同時(shí)接收你說話的聲音和被墻壁反射回來的聲音。</span> </p> <p> <span style="font-size:16px;">KTV話筒是低音的，適合室內(nèi)的環(huán)境使用。一般來講，室內(nèi)比較適合。</span> </p> <p> <span style="font-size:16px;">KTV話筒用在戶外比較開闊的地方，聲音會(huì)有點(diǎn)小，不過要求不是很高的話也是適用的。</span> </p> <p> <span style="font-size:16px;">無論是KTV話筒還是演出話筒都是帶點(diǎn)效果的。</span> </p> <p> <span style="font-size:16px;">大家要記住，不同類型的無線話筒要用在不同地方才能發(fā)揮它的效果。</span> </p> <p> <span style="font-size:16px;">貴的也不一定適合你，好用就行哈。</span> </p> <span style="font-size:16px;"></span> <p> <br /> </p><p> <span style="font-size:16px;">唱歌話筒大科普——唱歌麥克風(fēng)選購的小技巧</span> </p> <p> <br /> </p> <p> <span style="font-size:16px;">1、普通話筒和專業(yè)話筒有什么區(qū)別？</span> </p> <p> <br /> </p> <p> <span style="font-size:16px;">相當(dāng)于卡片相機(jī)與單反相機(jī)的區(qū)別。用QQ聊天把妹時(shí)，你頭戴耳機(jī)上的叫駐極體話筒，成本不超過一塊錢，但并不影響你和MM談人生聊理想。而專業(yè)話筒不但要能拾取到聲音，而且對(duì)音色有很高要求。錄音師追求好的話筒，和攝影師追求好的鏡頭差不多。</span> </p> <span style="font-size:16px;"></span><span style="font-size:16px;">2、專業(yè)話筒的種類有哪些？</span><span style="font-size:16px;"></span> <p> <br /> </p> <p> <br /> </p> <p> <span style="font-size:16px;">動(dòng)圈話筒：非專業(yè)場(chǎng)合，例如KTV，見到多的就是動(dòng)圈話筒。它的原理是話筒頭里的振膜帶動(dòng)線圈振動(dòng)，切割磁力線產(chǎn)生電信號(hào)，通過話筒線傳遞給下一級(jí)設(shè)備。它的優(yōu)點(diǎn)是結(jié)構(gòu)簡單、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> <br /> </p> <p> <span style="font-size:16px;">電容話筒：錄音領(lǐng)域應(yīng)用的多的話筒。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)，所以電容話筒非常靈敏。注意電容話筒需要一個(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>

</p> <p> <span style="font-size:16px;">BBSU-1500S應(yīng)用了型的防干擾技術(shù)——數(shù)字導(dǎo)頻技術(shù)，有效屏蔽雜波干擾，解決串頻問題。和發(fā)射器自動(dòng)對(duì)頻時(shí)，由麥克風(fēng)里的芯片將一組全新且的身份ID碼發(fā)送到麥克風(fēng)芯片中，修改麥克風(fēng)發(fā)射頻率的同時(shí)，還同步了身份ID碼并鎖定，麥克風(fēng)依靠這的ID碼作為信號(hào)識(shí)別，其它頻率電波就無法產(chǎn)生干擾，就算是相同頻率電波都無法干擾。在實(shí)際使用中，特別是在大型娛樂KTV包房的工程安裝中，數(shù)字導(dǎo)頻技術(shù)起到了非常大的優(yōu)勢(shì)。因?yàn)榉块g數(shù)量多，需要使用很多套無線話筒，在這個(gè)環(huán)境中頻率分配得不好就直接影響正常使用，沒有數(shù)字導(dǎo)頻技術(shù)之前， KTV工程安裝時(shí)需要經(jīng)過精密的計(jì)算才能規(guī)劃出完美的頻率分布，這要花費(fèi)大量的時(shí)間。時(shí)間就是金錢，節(jié)省時(shí)間等于節(jié)省成本，增加收入。BBS U-1500S使用了數(shù)字導(dǎo)頻技術(shù)，不但能極大減少安裝調(diào)試時(shí)間，同時(shí)在正常使用中還能避免外界雜波的干擾，帶來良好的使用體驗(yàn)。</span> bbs話筒哪個(gè)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BBS專業(yè)娛樂話筒哪個(gè)好</p><p
