A High Frequency Acoustic Focuser

Abstract

The invention discloses a high-frequency sound wave focuser. It comprises: a conical core; a truncated core; the large end of the truncated core and the bottom surface of the conical core have the same diameter and are connected together; a horn; the conical core is arranged in the cavity of the horn, and the There is a space between the horn and the conical core. The present invention also provides a sound collecting unit, which is composed of the above-mentioned high-frequency sound wave focuser and a coaxial horn; the high-frequency sound wave focuser is arranged at the high-pitched outlet of the coaxial horn, and the horn is connected to the coaxial horn. connected to the coaxial speakers. The invention can divide treble and bass to overcome the interference of different frequencies; the timbre is accurate; the high and low speakers can be freely selected and matched, so that the timbre can achieve high fidelity effect; the output power and sound pressure level are greatly improved regardless of the high frequency sound wave focus Whether it is a sound collector or a concentrator, the work efficiency is very high.

Description

technical field [0001] The invention relates to a high-frequency sound wave focuser. Background technique [0002] At present, the application of tweeters in the market requires sound waves to be used at a certain projection angle. There is a loudspeaker using planar magnetic technology that can control the angle of high-frequency sound waves to a small size. But its sound quality is poor, and the sound pressure of UHF and ULF is low. The reason is that a planar magnetic speaker works with a large diaphragm, and all sound frequencies are emitted on one diaphragm. Therefore, the superposition and cancellation of different frequencies will occur on the diaphragm to affect the sound quality. [0003] There is also a product that installs a horn on a coaxial horn. A horn is installed on the paper cone bass, and an ax-like core is installed in the treble horn. Its goal is to control the sound wave angle to be 6° flat and 120° wide within a flat and wide triangular shape rang...

AI Technical Summary

Problems solved by technology

Its goal is to control the angle of the sound wave at 6° flat, and the width is within the range of a flat and wide triangle shape of 120°, so the angle is too large, and the low-frequency effect is not good.
