Abstract

The invention belongs to the technical field of sound equipment, and particularly relates to a medium-high frequency composite waveguide horn device which comprises a high-frequency composite waveguide mechanism and medium-frequency compression waveguide mechanisms symmetrically arranged on the two sides of the high-frequency composite waveguide mechanism. The high-frequency composite waveguide mechanism comprises a sound amplification waveguide and a tweeter; the sound amplification waveguide is provided with at least two sound amplification cavities in a penetrating manner, two ends of each sound amplification cavity respectively form a sound outlet and a sound inlet at the front end and the rear end of the sound amplification waveguide, and the sound amplification cavities are gradually enlarged from one end of the sound inlet to one end of the sound outlet; sound inlets of the two sound amplification cavities are respectively provided with a tweeter; the intermediate-frequency compression waveguide mechanism comprises a compression waveguide and an alto horn; the compression waveguide is provided with at least one sound wave compression channel in a penetrating manner, two ends of the sound wave compression channel respectively form a leading-out port and a leading-in port at the front end and the rear end of the compression waveguide, and the width of the sound wave compression channel is reduced from one end of the leading-in port to one end of the leading-in port; the leading-in port is provided with an alto horn; the two sound outlets and the two lead-out ports face the same direction.

Description

technical field [0001] The invention belongs to the technical field of audio, and in particular relates to a medium and high frequency composite waveguide horn device and a sound box. Background technique [0002] The horn refers to a channel with a specific shape installed in front of the horn, which can compress and amplify the sound wave, and can also constrain and change the propagation direction. In the treble part of the audio industry, some are a combination of a waveguide and a horn, and some simply use a single horn. When the treble waveguide speaker is used alone, it is often used in conjunction with the mid-range audio. Due to the limitations of the design principle, it is difficult to further improve the high power and high-pitched directivity, and it is impossible to achieve long-range sound pressure and low distortion. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a medium and high frequency composite waveguide horn dev...
