PHASE PLUG-IMPLANTED HIGH-PITCH HORN FOR SOUND AMPLIFICATION

摘要

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.
