音响是按照一定的结构、由多个扬声器排列成一条一线或曲线、并将其安装在一个柱状箱体中组成，并且扬声器间距相等，同相工作。在水平面上线阵列的辐射特性与普通扬声器的辐射特性相似；在垂直平面上，其指向性比较尖锐，它具有以下4点优点：
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)线阵音响器材音箱具有很强的向前辐射和非常好的抑 制偏轴旁瓣波束的能力。利用线阵列的垂直指向性，包括对低频和超低频范围的指向性控制。可以讲主声束辐射到听众席，供给较强的直达声。从而使声音能 量有用地集中到观众区，减弱混响干扰及周围的反射声，提高声音清晰度。
(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)利用线阵列的柱面波特性，补偿远处观众席因距离加大声强衰减过多的缺 陷，使声场分布更加均匀。
(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)水平覆盖范围不受垂直阵列模块数量的影响，仍保持单个模块的水平覆盖特性。
(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)利用方向性强的特点，合理布局，能可靠的抑 制声反馈，提高音响系统传声增益。
(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.
办迟惫音响是在实际应用中要注意扬声器的链接。音柱内扬声器的链接应从阻抗匹配要求考虑，连接后的总阻抗可以通过并联、串联的组合方式来得到。
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.
