style="font-size:16px;">研發(fā)工程師們接到一項(xiàng)研發(fā)任務(wù)，可能是一個(gè)產(chǎn)品構(gòu)想或產(chǎn)品要求，這個(gè)構(gòu)想可能會(huì)描述產(chǎn)品的目標(biāo)市場(chǎng)和用戶、產(chǎn)品的應(yīng)用場(chǎng)景、功能需求和性能指標(biāo)，這些問題是著手研發(fā)之前需要初步明確的。</span> </p> <p> <span style="font-size:16px;">在產(chǎn)品構(gòu)想和要求比較明確之后，研發(fā)團(tuán)隊(duì)開始“編譯”——把文字或數(shù)字表述的產(chǎn)品要求編譯成產(chǎn)品雛形。比如對(duì)于一款音箱來說，需要考慮它是點(diǎn)聲源還是線聲源？單元的構(gòu)成如何？有源分頻還是無源分頻？箱體的外形尺寸如何？指向角度多少度？研發(fā)團(tuán)隊(duì)會(huì)根據(jù)經(jīng)驗(yàn)并借助一些設(shè)計(jì)軟件，做一個(gè)初步的規(guī)劃。借助WinISD、BassBox Pro這一類軟件，工程師可以根據(jù)備選的揚(yáng)聲器單元參數(shù)和箱體類型（密閉式、倒相式等）計(jì)算得到箱體的重要參數(shù)，包括容積、尺寸等。這一“編譯”過程是研發(fā)初期重要的步驟，一般由研發(fā)團(tuán)隊(duì)的負(fù)責(zé)人——研發(fā)總監(jiān)親自指導(dǎo)完成。這時(shí)候，產(chǎn)品雖然八字還沒有一撇，但是它的大致樣貌已經(jīng)存在于研發(fā)總監(jiān)的腦海中了。</span>

style="font-size:16px;">音響的本質(zhì)意義</span> </p> <p> <span style="font-size:16px;"> 音響對(duì)于現(xiàn)在的人們而言并非陌生，而對(duì)于音響一詞的解釋對(duì)于很多人來說確實(shí)模糊不清。那么對(duì)于音響的簡(jiǎn)單介紹就是，音響中的“音”就是聲音，如果從物理角度來解釋，音就是物體無規(guī)則振動(dòng)發(fā)出來的聲響稱為聲音，但音有“樂音”與“噪音”之分，“響”也是由音產(chǎn)生出來的一種介質(zhì)，但其只是發(fā)聲體經(jīng)過空氣體現(xiàn)發(fā)聲源的一種亮度(響度)，所以“音”與“響”都隸屬于聲音本質(zhì)，只不過是書意上有所解釋不同而已。音響作為高科技產(chǎn)物，它參與傳統(tǒng)戲曲舞臺(tái)藝術(shù)之中，起到了一個(gè)很好的服務(wù)作用，但是這種服務(wù)非同凡響。</span> </p> <p> <span style="font-size:16px;"> 隨著社會(huì)進(jìn)步的步伐不斷發(fā)展，音響在戲曲舞臺(tái)藝術(shù)中也起到了極其重要的作用，在戲曲藝術(shù)中，可以說得上是不可缺少的一個(gè)重要成員了。其與戲曲舞臺(tái)藝術(shù)之間是起到了相互協(xié)調(diào)和相互依存的共性原則。在我們傳統(tǒng)的戲曲藝術(shù)舞臺(tái)表演中，音響可以說在演員的唱，與樂隊(duì)的傳音是一個(gè)重要的媒介，只有通過利用音響的作用才能更好地傳送到臺(tái)下每一位觀眾的耳朵里，達(dá)到傳遠(yuǎn)致聽的藝術(shù)效果，從而突出戲曲舞臺(tái)藝術(shù)的表演效果。使得戲曲藝術(shù)能夠達(dá)到更好的藝術(shù)表現(xiàn)。</span> </p><h1> <span style="font-size:16px;">精心選擇音響設(shè)備，保證音響設(shè)備的專業(yè)化水平</span> </h1> <p> <span style="font-size:16px;">調(diào)音臺(tái)均衡器的頻段調(diào)節(jié)在音響設(shè)備的調(diào)音臺(tái)上有均衡器，可以通過它來對(duì)舞臺(tái)的人聲進(jìn)行美化和修飾，運(yùn)用音頻的調(diào)節(jié)來提高舞臺(tái)的藝術(shù)表現(xiàn)力。調(diào)音臺(tái)的均衡器可以分成四個(gè)不同的頻段分別是：</span>

style="font-size:16px;">第三，MID高音，200～600赫茲，這一頻段能夠影響到影響到音色的力沖和結(jié)實(shí)度;第四就是低音，在20～200赫茲之間，通過低音可以調(diào)節(jié)音色的渾厚度和豐滿度，讓聲音更加富有性。通過對(duì)四個(gè)頻段的調(diào)節(jié)能夠達(dá)到不同的音響效果，將高頻段的頻率適當(dāng)調(diào)弱，播放的音色就會(huì)更加富有色彩、韻味;但如果將高頻段的頻率調(diào)高，那么音響的音色就會(huì)變得尖銳刺耳。將中頻段的頻率調(diào)弱，音色就會(huì)表現(xiàn)出幽暗、朦朧的感覺，但如果將中頻段的頻率調(diào)得過強(qiáng)，音色就會(huì)顯得十分呆板，缺少韻味;將低頻段的頻率調(diào)得過高音色就會(huì)變得十分生硬、缺少藝術(shù)活力。</span>

style="font-size:16px;">舞臺(tái)音響有哪些常見的故障，這是平時(shí)我們需要注意的。只有了解到問題出現(xiàn)，才能針對(duì)這些做得更好，發(fā)揮到音響的效果。下面給大家介紹關(guān)于音響7方面常見的故障，一起看看吧。</span> </p> <p> <br /> </p> <p> <br /> </p> <p> <span style="font-size:16px;">1、線路需按標(biāo)準(zhǔn)連接。常見系統(tǒng)交流干擾聲大就是線路連接工藝沒有做好造成的，還有系統(tǒng)中有平衡轉(zhuǎn)不平衡及不平衡轉(zhuǎn)平衡接法的一定要按標(biāo)準(zhǔn)連接，另外不要用劣質(zhì)接插件。</span> </p> <p> <br /> </p> <p> <br /> </p> <p> <span style="font-size:16px;">2、效果回路處理。應(yīng)該取推子的后置信號(hào)，避免效果不受控引起話筒嘯叫，返回有條件占用一路通道，這樣調(diào)試更方便。</span> </p> <p> <br /> </p> <p> <br /> </p> <p> <span style="font-size:16px;">3、如何處理低音信號(hào)。一是不做電子分頻用全頻信號(hào)直接給功放推動(dòng)音箱，這樣有聲音也不至于燒壞單元，但低單元發(fā)全頻聲音可想而知。如從系統(tǒng)中不恰當(dāng)位置取得信號(hào)也會(huì)給現(xiàn)場(chǎng)控制帶來不必要的麻煩。二是不知從系統(tǒng)何處提取低音信號(hào)做處理。</span> </p> <p> <br /> </p> <p> <br /> </p> <p> <span style="font-size:16px;">4、系統(tǒng)電平問題。一是功放靈敏度控制開關(guān)打開不足，二是系統(tǒng)沒有做零電平調(diào)整。有時(shí)調(diào)音臺(tái)通道推一點(diǎn)點(diǎn)輸出已很大，這種情況會(huì)影響系統(tǒng)的動(dòng)態(tài)和失真度。</span> </p> <p> <br /> </p>

style="font-size:16px;">確保音響設(shè)備組合的專業(yè)化水平</span> </p> <p> <br /> </p> <p> <span style="font-size:16px;">隨著時(shí)代的發(fā)展，現(xiàn)代觀眾對(duì)舞臺(tái)的要求更高了，不僅要滿足視覺感受上的愉悅，同時(shí)還要完成聽覺的審美過程。因此，為了優(yōu)化舞臺(tái)音響效果，關(guān)鍵的因素之一，是要精心挑選好音響設(shè)備。</span> </p> <p> <br /> </p> <p> <span style="font-size:16px;">舞臺(tái)音響系統(tǒng)是由信號(hào)源設(shè)備、信號(hào)處理設(shè)備、功率放大器和揚(yáng)聲器等設(shè)備連接組合而成，通過調(diào)音師的調(diào)試，以達(dá)到良好的舞臺(tái)音響效果。</span> </p> <p> <span style="font-size:16px;"> </span> </p> <p> <span style="font-size:16px;"> 確保音響設(shè)備配置專業(yè)化。音響設(shè)備是保證舞臺(tái)音響效果的重要基礎(chǔ)，它直接關(guān)系到舞臺(tái)藝術(shù)呈現(xiàn)的成功與失敗。話筒功率放大器和音箱的頻率范圍十分重要，同時(shí)調(diào)音臺(tái)是音響設(shè)備中尤為重要的一種設(shè)備，是音響設(shè)備的重中之重。使用良好的音響系統(tǒng)可以美化演員的舞臺(tái)表演，如推進(jìn)舞臺(tái)表演情節(jié)的發(fā)展，渲染整個(gè)舞臺(tái)氣氛。因此，要利用先進(jìn)的電聲器件和設(shè)備作為舞臺(tái)擴(kuò)聲，才能完美地達(dá)到語言的清晰和音樂作品的豐滿度，營(yíng)造令人滿意的舞臺(tái)效果。</span> </p> <p> <br /> </p> <p> <span style="font-size:16px;"> 確保麥克風(fēng)的選擇與話筒拾音到位。在麥克風(fēng)的選擇方面，根據(jù)不同的演出者應(yīng)用不同的麥克：主持人說話時(shí)多用配備套頭的麥克，這樣既可以避免說話時(shí)由于帶"b""p"的詞語氣流的震動(dòng)而發(fā)出的"蓬蓬"聲，也可以在有風(fēng)的室外場(chǎng)地避免"呼呼"聲出現(xiàn)。話筒拾音分為人聲拾音和器樂拾音。</span>
