音响设备的音质效果不容置疑，但是由于可听声波通常都是360度向外辐射出去的，所以，好的音响设备发出来的声波会随着传播距离产生衰减，同时也会造成扰民。为了减少这两种现象，可以使用以下方法让
山东会议室音响的声波实现定向传播。
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、利用音罩加强指向性
1. Use the sound cover to strengthen the directivity
让音响设备发出的声音集中起来加强其传播的指向性，采用聚音罩可以说是简单可行的方法之一，这种方法类似于灯罩，只要在高频扬声器上罩个大半球形的罩子，人在聚音罩下方即可清楚听到声音。
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、利用号角加强指向性
2. Use horn to strengthen directivity
第二种方法是在音响设备的喇叭单元前加上号角，由于中高频音响由于的垂直、水平方向可以控制在一百度以内，该角度以外则可以大幅衰减，所以号角音箱的低频没有变化，但是中高频音箱的指向性却有效得到增强。
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&濒诲辩耻辞;线性阵列&谤诲辩耻辞;加强指向性
3. Use Linear Array to enhance directivity
除了号角外，另外一个方法就是让音箱发出柱面波，用多只喇叭单元进行排列，广播音柱是比较容易见到的柱面波音箱，很显然，它的垂直指向性很强，但是水平指向性一般。如果想要增强水平指向性，可以为音响设备采用&濒诲辩耻辞;线性阵列&谤诲辩耻辞;音箱或音柱，即将音箱或音柱排列成一行。再在这些中高音单元前加声学透镜，将音频信号数字化后进行分频及复杂的数字效果处理，然后转换为模拟信号分别对每个单元独立放大驱动。
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.
采用以上这几种方法能够让音响设备发生的声波可以做到定向传播，从而减少了声波在空气传播中的衰减，更加可以避免对左邻右舍的干扰。希望发烧友们能够参考音响设备的公司提供的方法，在满足自己享受音乐的同时也不要打扰他人的休息。更多相关内容就来我们网站
