Behind-Display Loudspeaker Layout for Low-Distortion Audiovisual Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional audio-visual systems in venues occupy valuable space and require covering to avoid obstructing the view, leading to acoustical distortion and vibration issues.
Innovation Solution
An integrated audio-visual system with loudspeakers positioned behind visual displays, using specially designed displays with openings and a predetermined displacement to minimize acoustical distortion and vibration, allowing sound to propagate effectively while maintaining a clear visual representation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If conventional loudspeakers are positioned in plain sight of spectators, then sound delivery is effective, but they occupy valuable venue space and obstruct the visual display
Solution Approach 1:
The loudspeakers are repositioned from the traditional front-and-center location to a location behind the visual display, utilizing the spatial dimension behind the display area. This dimensional relocation allows the audio system to operate without obstructing the visual field or consuming prime venue space, while maintaining effective sound delivery through strategic placement and directional acoustic design
2Area of stationary object
If loudspeakers are covered to avoid obstructing the view, then visual display is clear, but acoustical distortion and vibration issues arise
Solution Approach 1:
The loudspeakers are extracted from the traditional front-and-center position and relocated to behind the visual display. This extraction removes the source of the problem (loudspeakers in the field of view) while the acoustic coverage is maintained through the spatial arrangement and directional characteristics of the relocated speakers, eliminating the need for covering while preventing obstruction
Solution Approach 2:
The visual display structure itself serves as an intermediary element that the loudspeakers are positioned behind. This intermediary arrangement allows the display to remain unobstructed while the acoustic system operates in the space behind it, using the display structure as a spatial reference that enables both visual clarity and acoustic effectiveness without direct conflict
3Area of stationary object
If loudspeakers are positioned behind visual displays, then space is optimized and view is clear, but acoustical distortion and vibration may increase
Solution Approach 1:
The acoustic system employs directional loudspeakers with specific acoustic radiation patterns that concentrate sound energy toward the audience area while minimizing dispersion toward the visual display. This local quality control of acoustic energy distribution allows the speakers to be positioned behind the display without causing significant distortion, as the acoustic field is locally optimized for the intended listening area

AI summary
An integrated audio-visual system is disclosed for delivering an event to one or more spectators. The integrated audio-visual system includes one or more loudspeakers that are positioned behind one or more visual displays to be effectively behind the one or more visual displays to be shielded from the field of view of the one or more spectators. The one or more visual displays are specially designed and manufactured to allow sound associated with the event to propagate from the one or more loudspeakers with minimal acoustical distortion and/or minimum acoustical vibration while presenting a visual representation of the event to the one or more spectators. Moreover, the one or more loudspeakers and the one or more visual displays are situated to be a predetermined displacement from each other to further minimize acoustical distortion.
