Abstract
Description
Technical Field
[0001] The present invention relates to a sound amplification method and device. Background Art
[0002] Traditional sound reinforcement technologies rely on speakers directly pointing at the audience, and multiple speakers need to be installed at preset positions, such as bookshelf speakers, 2.1 stereo, 5.1, 7.1, 9.1 panoramic sound, etc. However, this method requires considering the radiation range and directivity of the sound source, often requiring complex acoustic space design and wiring, resulting in high equipment costs, inconvenient maintenance, and insufficient flexibility. Summary of the Invention
[0003] The present invention provides a sound amplification method and device based on directional sound technology. By projecting sound onto a preset obstacle and utilizing the sound reflection principle, the sound is directionally transmitted to a predetermined area, achieving precise sound projection. This method can reduce equipment costs, improve flexibility, and does not require complex acoustic space design.
[0004] To achieve the above object, the present invention adopts the following technical solutions. A sound amplification method: Project sound onto an obstacle through directional sound technology to form a virtual speaker; when the directional sound encounters the obstacle, it is reflected at a predetermined angle to a predetermined area to complete sound projection, as Figures 1 to 7 shown.
[0005] The directional sound technology projects sound onto an obstacle through ultrasonic directional sound technology to form a virtual speaker. At this time, the obstacle serves as a virtual sound source and projects the sound onto a predetermined listening area through sound reflection, as Figures 1 to 7 shown.
[0006] The directional sound amplification technology is achieved through acoustic phasing and / or sound interference technology and / or acoustic array control technology.
[0007] The sound amplification scheme can be in a single-channel, dual-channel, or multi-channel manner, as Figures 1 to 7 shown.
[0008] The sound amplification device is integrated at a central point and projects the directional sound onto a predetermined area, as Figures 1 to 7 shown.
[0009] The directional sound amplification device is composed of multiple independent units spliced and combined, as Figures 8 to 11 shown.
[0010] The directional sound amplification device is angle-adjustable, as Figures 13 to 15 shown.
