Building Material With 3D Netlike Structure for Loudspeaker Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing building materials that incorporate loudspeakers struggle to balance improved appearance with enhanced acoustic performance, as decoration covers that reduce visibility often compromise sound radiation, and those that improve sound radiation typically increase visibility.
Innovation Solution
A building material with a plate-like structure featuring openings, a loudspeaker in a second space opposite the openings, and a three-dimensional netlike structure made of fibrous members intertwined to minimize visibility while maintaining high acoustic transparency, using materials like resin, metal, or glass, and optionally incorporating a light source for further aesthetic enhancement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a decoration cover is used to reduce the loudspeaker's visibility, then the appearance is improved, but the acoustic performance deteriorates due to compromised sound radiation
Solution Approach 1:
The patent applies a netlike structure with fibrous members that create a porous configuration between the loudspeaker and the building material surface. This porous structure allows sound waves to pass through while providing visual screening, thus improving appearance without significantly compromising acoustic performance. The fibrous members are arranged to create sufficient open space for sound transmission while maintaining aesthetic coverage.
Solution Approach 2:
The netlike structure acts as an intermediary element positioned between the loudspeaker and the building material surface. This intermediate layer provides visual screening functionality while maintaining acoustic transparency, resolving the contradiction between appearance improvement and acoustic performance preservation.
2Reliability
If the loudspeaker is made more visible to improve sound radiation, then acoustic performance is improved, but the appearance deteriorates
Solution Approach 1:
The netlike structure with its porous configuration allows sound waves to pass through effectively while providing visual screening. The fibrous members are spaced and arranged to ensure sufficient acoustic transmission while maintaining aesthetic coverage, thus improving appearance without significantly compromising acoustic performance.
3Shape
If a solid covering is used to hide the loudspeaker, then appearance is improved, but sound transmission efficiency deteriorates
Solution Approach 1:
The patent employs a netlike structure with fibrous members that creates a porous configuration, allowing sound waves to pass through while providing visual screening. This porous design ensures that sound transmission efficiency is maintained while achieving the desired appearance improvement through partial coverage.
Solution Approach 2:
The netlike structure introduces a three-dimensional arrangement of fibrous members that creates multiple pathways for sound transmission. This dimensional complexity allows sound to pass through the structure from multiple angles and paths, maintaining sound transmission efficiency while providing effective visual screening from the primary viewing direction.

Function Achieved in This Case
This configuration ensures both improved appearance and acoustic performance by reducing the loudspeaker's visibility while maintaining sound transmission efficiency, even with multiple loudspeakers having different or similar reproduction bandwidths.
