Description

Technical Field

[0001] The utility model belongs to the technical field of loudspeakers, and in particular relates to a loudspeaker digital beam array module. Background Art

[0002] The speaker digital beam array module utilizes digital signal processing (DSP) and an array of multiple speaker units to achieve directional propagation of sound waves and spatial sound field control by controlling the phase and amplitude of each speaker unit. This module can achieve sound wave focusing, directivity control, and optimization of spatial sound field distribution.

[0003] However, in the existing technology, the speaker system used in most sound reinforcement systems is a line array speaker, which is composed of multiple speakers arranged in a straight line. Line array speakers are limited to controlling the directionality of sound in one dimension (usually the vertical direction), which limits their ability to control the sound field in another direction (usually the horizontal direction). In some application scenarios, there are limitations in directivity control, sound field distribution, and spatial acoustic effects, which may lead to uneven sound field coverage, weak ability to reproduce complex sound fields, difficulty in adapting to changing audience layouts or sound field environments, and inability to meet the needs of complex acoustic environments.

[0013] A plurality of connecting strips; when each loudspeaker digital beam dot matrix module is arranged in an array in the short axis direction, it is connected between each of the third plug-ins, and the screws are connected to the adjacent connecting holes on the outside.

[0014] Beneficial effects of the present invention: A loudspeaker digital beam array module can achieve multi-dimensional sound coverage and directivity control by arranging loudspeaker digital beam dot matrix modules in an array along the long axis and short axis directions.
