High-pitch horn with phase plug

Abstract

The invention discloses a high-pitch horn with a phase plug. The high-pitch horn comprises an inverted-circular-truncated-cone-shaped high-pitch horn and an inverted-cone-shaped phase plug installed in the high-pitch horn. The inner side surface of the high-pitch horn is matched with the side surface of the phase plug; a high-frequency compression driver is arranged at the bottom of the high-pitchhorn, a plurality of positioning nails are evenly distributed on the inner circumferential wall of the high-pitch horn, positioning holes corresponding to the positioning nails are formed in the outer circumferential wall of the phase plug, and notches which are symmetrical left and right are formed in the left side and the right side of the upper portion of the phase plug. The high-frequency compression driver and the high-pitch horn do not generate sound wave resonance, sound waves do not interfere with each other, acoustic paths reaching an outlet are equal, fluctuation of a frequency response curve is small, standing waves and crossover distortion are small, off-axis frequency response diffusion characteristics and axial frequency response diffusion characteristics are smooth, and thehigh-pitch effect is good.

Description

technical field [0001] The invention relates to a treble horn, in particular to a treble horn with a phase plug. Background technique [0002] The existing treble horn, the sounder and the horn will generate sound wave resonance, and the sound waves will interfere with each other, and the acoustic paths to the exit are not equal, resulting in fluctuations in the frequency response curve, large standing waves and crossover distortion, and some treble horns are installed inside Phase plug, but the off-axis frequency response diffusion characteristics and on-axis frequency response diffusion characteristics are still not smooth enough, and off-axis frequency response peaks and valleys often appear. Therefore, in order to avoid the shortcomings existing in the prior art, it is necessary to improve the prior art. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings and deficiencies in the prior art, and provide a tweeter horn ...
