Abstract
(EN)
A phase plug-implanted high-pitch horn for sound amplification comprising: a high-pitch driver (1), a throat pipe composed of horn throat pipe side plates (2) which are arranged in bilateral symmetry, an implanted phase plug (3), and a horn guide plate (4); the inlet of the throat pipe is connected with the high-pitch driver (1) while the outlet is connected with the horn guide plate (4) through a connecting flange (5); and the implanted phase plug (3) is connected with the horn throat pipe side plates (2) through a positioning bolt, and is fixed in the center of an passage within the throat pipe. With the path compensation effect of the phase plug implanted in the throat pipe, the phase plug-implanted high-pitch horn for sound amplification eliminates the interference caused by path difference, optimizes the sound amplification effect, and improves the reproducibility and fidelity of system.

Pavillon d'aigus avec bouchon de phase implanté pour amplification de son, comportant: un excitateur (1) d'aigus, un tube à col composé de plaques latérales (2) de tube à col de pavillon qui sont disposées en symétrie bilatérale, un bouchon (3) de phase implanté, et une plaque-guide (4) de pavillon; l'entrée du tube à col est reliée à l'excitateur (1) d'aigus tandis que la sortie est reliée à la plaque-guide (4) de pavillon par l'intermédiaire d'une bride (5) de liaison; et le bouchon (3) de phase implanté est relié aux plaques latérales (2) de tube à col de pavillon par l'intermédiaire d'un boulon de positionnement, et est fixé au centre d'un passage à l'intérieur du tube à col. Du fait de l'effet de compensation de parcours du bouchon de phase implanté dans le tube à col, le pavillon d'aigus avec bouchon de phase implanté pour amplification de son élimine l'interférence causée par la différence de parcours, optimise l'effet d'amplification du son et améliore la reproductibilité et la fidélité du système.

一种扩声用植入相位塞式高音号角,包括:高音驱动器(1)、由左、右对称设置的号角喉管侧板(2)构成的喉管、植入式相位塞(3)、号角导向板(4);所述的喉管的入口与高音驱动器(1)相连,出口与号角导向板(4)通过连接法兰(5)相连;所述的植入式相位塞(3),通过定位栓与号角喉管侧板(2)连接,居中固定于喉管内通道中。所述扩声用植入相位塞式高音号角通过植入喉管内的相位塞的路径补偿作用,消除因路径差而产生的干涉,优化了扩声效果,提高了系统还原度及保真度。
