音響設(shè)備的音質(zhì)效果不容置疑，但是由于可聽聲波通常都是360度向外輻射出去的，所以，好的音響設(shè)備發(fā)出來的聲波會隨著傳播距離產(chǎn)生衰減，同時也會造成擾民。為了減少這兩種現(xiàn)象，可以使用以下方法讓
山東會議室音響的聲波實現(xiàn)定向傳播。
There is no doubt about the sound quality effect of sound equipment, but because audible sound waves usually radiate out 360 degrees, the sound waves emitted by good sound equipment will attenuate with the propagation distance, and also cause disturbance to the people. In order to reduce these two phenomena, the following methods can be used to realize directional propagation of sound waves in Shandong conference room.
1、利用音罩加強指向性
1. Use the sound cover to strengthen the directivity
讓音響設(shè)備發(fā)出的聲音集中起來加強其傳播的指向性，采用聚音罩可以說是簡單可行的方法之一，這種方法類似于燈罩，只要在高頻揚聲器上罩個大半球形的罩子，人在聚音罩下方即可清楚聽到聲音。
It is one of the simple and feasible methods to centralize the sound emitted by the audio equipment to strengthen the directivity of its transmission. This method is similar to the lampshade. As long as a large hemispherical cover is placed on the high frequency speaker, people can clearly hear the sound under the microphone.
2、利用號角加強指向性
2. Use horn to strengthen directivity
第二種方法是在音響設(shè)備的喇叭單元前加上號角，由于中高頻音響由于的垂直、水平方向可以控制在一百度以內(nèi)，該角度以外則可以大幅衰減，所以號角音箱的低頻沒有變化，但是中高頻音箱的指向性卻有效得到增強。
The second method is to add a horn in front of the speaker unit of the audio equipment. Because the vertical and horizontal directions of the medium and high frequency speakers can be controlled within 100 degrees, and the angle can be greatly attenuated, so the low frequency of the horn speaker does not change, but the directivity of the medium and high frequency speakers is effectively enhanced.
3、使用“線性陣列”加強指向性
3. Use Linear Array to enhance directivity
除了號角外，另外一個方法就是讓音箱發(fā)出柱面波，用多只喇叭單元進(jìn)行排列，廣播音柱是比較容易見到的柱面波音箱，很顯然，它的垂直指向性很強，但是水平指向性一般。如果想要增強水平指向性，可以為音響設(shè)備采用“線性陣列”音箱或音柱，即將音箱或音柱排列成一行。再在這些中高音單元前加聲學(xué)透鏡，將音頻信號數(shù)字化后進(jìn)行分頻及復(fù)雜的數(shù)字效果處理，然后轉(zhuǎn)換為模擬信號分別對每個單元獨立放大驅(qū)動。
In addition to the horn, another method is to make the speakers emit cylindrical waves, which are arranged by multiple speaker units. The broadcast sound column is a relatively easy to see cylindrical wave speaker. Obviously, its vertical directivity is very strong, but its horizontal directivity is general. If you want to enhance the horizontal directivity, you can use "linear array" speakers or sound columns for the audio equipment, that is, the speakers or sound columns are arranged in a row. Then add an acoustic lens in front of these tweeter units, digitize the audio signal, conduct frequency division and complex digital effect processing, and then convert it into analog signals to independently amplify and drive each unit.
采用以上這幾種方法能夠讓音響設(shè)備發(fā)生的聲波可以做到定向傳播，從而減少了聲波在空氣傳播中的衰減，更加可以避免對左鄰右舍的干擾。希望發(fā)燒友們能夠參考音響設(shè)備的企業(yè)提供的方法，在滿足自己享受音樂的同時也不要打擾他人的休息。更多相關(guān)內(nèi)容就來我們網(wǎng)站

Using these methods can make the sound waves generated by the audio equipment can be directionally transmitted, thus reducing the attenuation of the sound waves in the air transmission, and more can avoid interference to the neighbors. I hope that enthusiasts can refer to the methods provided by the brands of audio equipment, and do not disturb others' rest while satisfying their own enjoyment of music.
