Cylindrical wave strip-shaped coupler module

Abstract

The invention discloses a cylindrical wave strip-shaped coupler module comprising a strip-shaped NdFeB magnet, a plurality of voice coils, a strip-shaped vibration film and a horizontal control monomer, wherein the voice coils are installed on the strip-shaped NdFeB magnet, and connected with the strip-shaped vibration film together with the strip-shaped NdFeB magnet, and the strip-shaped vibration film is fixed between the strip-shaped NdFeB magnet and the horizontal control monomer. The module provided by the invention achieves the advantages of accurate coverage, long sound radiation transmission distance and high acoustic irradiation definition. Under the condition of good energy saving and environment protection effects, the volume and weight of the product are greatly reduced by theimproved structure, and under the condition of splicing to form the line sound source array loudspeaker group, the whole module does not have ultrahigh requirement on the load of the building, so thatthe application range of the product is increased virtually, and the acoustical problem that people are difficult to solve is solved.

Description

technical field [0001] The invention relates to loudspeaker unit products, in particular to a cylindrical wave strip coupler module. Background technique [0002] In the past, traditional loudspeaker unit products often rely on a single magnet to drive a voice coil to push a diaphragm. After this structure is formed into an array, it is often necessary to control specific frequency bands and must meet certain coupling conditions to improve the directivity control of sound waves. , it is necessary to add a waveguide to correct the phase of the sound wave, and its coupling effect on the high-frequency band of the sound wave, improvement of sound quality and radiation transmission distance are very limited. Especially for the frequency band above 8KHz, while the natural acoustic coupling of the specific frequency band cannot be achieved, it also increases the sound coloration and unnecessary weight. The coloring of the sound waves by its waveguide leads to distortion, and the ...

Problems solved by technology

[0002] In the past, traditional loudspeaker unit products often rely on a single magnet to drive a voice coil to push a diaphragm. After this structure is formed into an array, it is often necessary to control specific frequency bands and must meet certain coupling conditions to improve the directivity control of sound waves. , it is necessary to add a waveguide to correct the phase of the sound wave, which has a limited coupling effect on the high-frequency band of the sound wave, improvement of sound quality and radiation transmission distance.

Especially for the frequency band above 8KHz, while the natural acoustic coupling of the specific frequency band cannot be achieved, it also increases the sound coloration and unnecessary weight

The coloration of the sound wave by its waveguide leads to distortion, and the direct sound transmission distance of the sound radiation is also limited

If the coverage and shape of the sound cannot be precisely controlled, it will waste sound energy and easily stimulate unnecessary reflections and reverberation

It is also easy to cause adverse problems such as inaudible sound and muddy sound in the sound reinforcement system.
