16C 声柱形音箱

16C是一款被动两分频声柱扬声器,是本系列中体积最小的型号,内置4个4” 钕磁驱动单元和一个装在CD号角上的0.75”压缩驱动单元。高频号角能够产生 90° x 40° (水平 x 垂直) 的标称扩散角度。此外,该 4" 驱动单元通过单元前方的波导元件与箱体后方的阻尼口形成一个独特的低频心型扩散特性,这种设计能提供水平恒定90°的扩散角,并箱体后方实现宽带衰减大约18dB,这种心型指特性确保在扬声器后方能量最少化,以减少有害反射,使得整个聆听区域的声压分布均匀。同时,在使用话筒时能够有效提高反馈前增益。16C 扬声器的箱体背部由冲压铝材和金属挡板组成,箱体前面和两侧则由金属网罩保护。同时,箱体背面配有用于安装的 T 形导轨,和4级 Phoenix combicon 终端接头。xC系列音箱的标准颜色是白色和黑色,也可在各种 RAL 颜色中选用特殊颜色。

心型扩散特性

心型扩散特性

传统的声柱扬声器通常因其物理体积的限制,低于2 kHz后不能维持有效的水平方向性。而中低频率指向性更几乎是无方向性的,如右图虚线所示传统的声柱在自由场的声学条件下的水平极坐标图。而图中实线所示的心型指向特性是 16C 声柱扬声器,可见扬声器后方的声强有显著减小。

通常,声柱扬声器会被安装在墙壁或其它坚硬的平面前,墙壁平面的声学效果类似于镜像作用,如右图中的水平极坐标图;因为实际上室内的声能量覆盖除了来自声柱扬声器本身,也来源于其后方虚拟镜像源,而又因为传统声柱的虚拟镜像源与声柱本身具有相近的声压级输出;两者组合结果产生双极特性(沿两者中线收窄覆盖),合并后声能量覆盖贴近墙,如右图中虚线水平极坐标图所示。与之相反,16C 的独特之处在于其心型扩散特性能力,使安装于墙壁时能提供更均匀的覆盖和更有用的指向特性,如右图中实线水平极坐标图所示。
