音響是按照一定的結構、由多個揚聲器排列成一條一線或曲線、并將其安裝在一個柱狀箱體中組成，并且揚聲器間距相等，同相工作。在水平面上線陣列的輻射特性與普通揚聲器的輻射特性相似；在垂直平面上，其指向性比較尖銳，它具有以下4點優點：
Sound is in accordance with a certain structure, by a number of speakers arranged into a line or curve, and installed in a cylindrical box, and the speaker spacing is equal, in-phase work. In the horizontal plane, the radiation characteristics of the line array are similar to those of the ordinary loudspeaker; In the vertical plane, its directivity is sharp. It has the following four advantages
(1)線陣音響器材音箱具有很強的向前輻射和非常好的抑 制偏軸旁瓣波束的能力。利用線陣列的垂直指向性，包括對低頻和超低頻范圍的指向性控制。可以講主聲束輻射到聽眾席，供給較強的直達聲。從而使聲音能 量有用地集中到觀眾區，減弱混響干擾及周圍的反射聲，提高聲音清晰度。
(1) Linear array audio equipment speaker has strong forward radiation and very good ability to suppress off-axis sidelobe beam. Using the vertical directivity of line array, including the directivity control of low frequency and ultra-low frequency range. It can be said that the main sound beam radiates to the audience, providing strong direct sound. So that the sound energy can be effectively concentrated in the audience area, the reverberation interference and the surrounding reflected sound can be reduced, and the sound clarity can be improved.
(2)利用線陣列的柱面波特性，補償遠處觀眾席因距離加大聲強衰減過多的缺 陷，使聲場分布更加均勻。
(2) By using the cylindrical wave characteristics of the line array, the defect of excessive attenuation caused by the distance increase in the auditorium is compensated, so that the sound field distribution is more uniform.
(3)水平覆蓋范圍不受垂直陣列模塊數量的影響，仍保持單個模塊的水平覆蓋特性。
(3) The horizontal coverage is not affected by the number of vertical array modules, and still maintains the horizontal coverage characteristics of a single module.
(4)利用方向性強的特點，合理布局，能可靠的抑 制聲反饋，提高音響系統傳聲增益。
(4) The sound feedback can be reliably suppressed and the sound transmission gain of the sound system can be improved by using the strong directivity and reasonable layout.
ktv音響是在實際應用中要注意揚聲器的鏈接。音柱內揚聲器的鏈接應從阻抗匹配要求考慮，連接后的總阻抗可以通過并聯、串聯的組合方式來得到。
KTV audio is to pay attention to the link of speakers in practical application. The connection of loudspeakers in the voice column should be considered from the impedance matching requirements, and the total impedance after connection can be obtained through the combination of parallel and series connection.
