关于线阵
线性阵列音响是一组排列成直线、间隔紧密的辐射单元，并具有相同的振幅与相位，主要适用于大型流动演出、体育场馆、多功能报告厅、大型剧院等场合。场所大小对线性阵列音响的需求各有不同,无论场所如何 线性系列的最大目的在于既要让所有观众都能听到均匀的声音还必须保持较高的声效保真。
- Linear array sound is a group of closely spaced radiation units arranged in a straight line with the same amplitude and phase. It is mainly applicable to large mobile performances, stadiums, multi-function lecture halls, large theaters and other occasions. The demand for linear array sound varies from place size to place size. No matter how the place is, the biggest purpose of linear series is not only to enable all audiences to hear uniform sound, but also to maintain high sound fidelity.
线性阵列原理
线性阵列扬声器系统是由若干音箱在垂直面重叠组合，形成一个水平方向角度一定(一般为90。)垂直方向较窄的波束。一个室外运动场(距离可在100m以上)，有这样4条线性阵列系统就足以满足声场覆盖的要求，这就是线性阵列系统的优势所在。线性阵列系统常常有一点稍稍的弯曲，目的是为得到更大的覆盖角。主体部分对远场，弯曲部分对近场。使垂直指向性不对称，可在高频不足的部分聚集一些声能。
- The linear array speaker system is composed of several speakers overlapped in the vertical plane to form a certain horizontal angle (generally 90) Narrow beam in the vertical direction. For an outdoor sports field (the distance can be more than 100m), such four linear array systems are sufficient to meet the requirements of sound field coverage, which is the advantage of linear array systems. Linear array systems often have a slight bend in order to obtain a greater coverage angle. The main part is for the far field, and the bending part is for the near field. Asymmetrical vertical directivity can gather some sound energy in the part with insufficient high frequency.
线阵优点
其覆盖均匀，扩散度好。由于线性阵列的特点，在主轴垂直平面指向性呈窄波束，能量叠加可以远距离辐射。而线性列的弯曲部分下端覆盖近区，形成自近而远的覆盖。 并且线性阵列扩声音箱的改进更符合技术、工艺、安装的要求。
- It has uniform coverage and good diffusion. Due to the characteristics of linear array, the directivity in the vertical plane of the main axis is narrow, and the energy superposition can radiate in a long distance. The lower end of the bending part of the linear column covers the near area, forming a cover from near to far. And the improvement of linear array sound reinforcement box is more in line with the requirements of technology, process and installation.
会议功放与音响匹配要素
设计、安装一套会议音响设备时，不免遇到会议功放与音响的匹配问题。在音色方面，会注意其搭配是否相宜、适中。从技术方面考虑会议功放与音响的要素有：功率匹配、阻抗匹配、阻尼系数的匹配。如果我们在匹配时认识到上述几点，可使所有器材的性能得到充分的、较大的发挥。
- When designing and installing a set of conference audio equipment, it is inevitable to encounter the matching problem between conference power amplifier and audio. In terms of timbre, we will pay attention to whether the collocation is appropriate and moderate. From the technical point of view, the elements of conference power amplifier and audio are: power matching, impedance matching, damping coefficient matching. If we realize the above points when matching, the performance of all equipment can be fully and greatly exerted.
