Portable Sound Reflection Assembly for Variable Venues
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sound reflection technologies face challenges in effectively reflecting sound waves in general settings such as open arenas or trade shows with variable audience areas and sound source positions, unlike well-defined settings like theaters.
Innovation Solution
A portable sound reflection assembly that integrates a display and directional speaker elements with a sound reflection section, where directional sound waves are directed towards a reflective surface to create a virtual speaker configuration, allowing for expansive sound image rendering and omnidirectional sound wave distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If sound reflection is designed for well-defined settings like theaters, then sound reflection quality is improved, but adaptability to general settings like open arenas deteriorates
Solution Approach 1:
The sound reflection assembly is designed to be portable and reconfigurable, allowing it to adapt to different settings dynamically. The assembly can be positioned at various locations and orientations in open arenas, trade shows, and other general settings rather than being fixed in a single predetermined location, enabling it to serve multiple environments effectively
2Adaptability or versatility
If a portable sound reflection assembly is used in general settings, then adaptability is improved, but sound reflection effectiveness deteriorates
Solution Approach 1:
The assembly incorporates a sound reflection section with specific surface characteristics designed to reflect sound waves effectively. This localized sound reflection capability is integrated into a portable structure, allowing the assembly to provide targeted sound reflection in specific directions while maintaining portability and adaptability to different settings
3Area of stationary object
If directional speaker elements are used to create virtual speaker configuration, then sound coverage area is improved, but device complexity increases
Solution Approach 1:
The sound reflection section acts as an intermediary element that works with the directional speaker elements to create the virtual speaker configuration. By reflecting sound waves from the directional speakers, the reflection section expands the effective sound coverage area without requiring additional physical speakers, thus managing device complexity while improving coverage
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The assembly provides high-quality sound field images and expansive sound coverage, effectively simulating sound sources from wide angles, enhancing the auditory experience in various settings without obstructing the display or audience view.
Implementation Method 1
Sound waves as physical waves may be reflected at physical boundaries separating different materials with different sound wave propagation properties

AI summary
A sound reflection assembly comprises a rigid structure having a sound reflection section and a support section, a rigid part in the support section, etc. A directional sound generation module is placed on the rigid part. The directional sound generation module is spatially oriented to direct sound waves generated by one or more speaker elements in the directional sound generation module towards the sound reflection section to be reflected by the sound reflection section towards an audience in an audience area in front of the sound reflection assembly. The directional sound generation module may be a sound bar.
