1.1.4渐开形线阵列渐开线形阵列是一种可以预测的恒定指向阵列,虽然此形阵列由上至下声能布局并不均匀,但在远、近声场覆盖的过渡却十分平滑,充分利用了声波在大气中的衰减作用,将不利变为有利,这也恰好为大中型场地提供了更加完美的覆盖特性。箱体角度按一定比例递增是渐开线形阵列外形布局的特点,递增比例要限定在1°~2°内,这样声能分布才能变得均匀平滑,避免出现J形阵列的“断点”问题。
1.1.4 Involute line array An involute line array is a predictable constant pointing array. Although the array is not uniform in sound energy distribution from top to bottom, the transition of the far and near sound field coverage is very smooth, Making full use of the attenuation effect of sound waves in the atmosphere, the disadvantage becomes favorable, which also provides more perfect coverage characteristics for large and medium-sized venues. Increasing the cabinet angle by a certain percentage is the shape of the involute array layout features, increasing the proportion to be limited to 1 ° ~ 2 °, so that the distribution of sound energy to become uniform and smooth, to avoid the J-shaped array "problem.
