Speaker Module Dual Sound Channels for Uniform Volume Output
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The speaker module in electronic devices is often positioned eccentrically due to interference with other components, leading to variations in sound volume output, which affects sound performance.
Innovation Solution
The electronic device incorporates a speaker module with a first and second sound channel, including a space between supports, to connect the speaker module to sound outlets positioned in opposite directions, ensuring consistent sound volume output.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the speaker module is disposed eccentrically to avoid interference with the camera module, then the assembly convenience is improved, but the sound volume uniformity deteriorates
Solution Approach 1:
The sound hole is divided into multiple segments (first sound hole, second sound hole, third sound hole) positioned at different locations. Each segment connects to the speaker module through separate sound channels, allowing independent optimization of sound transmission paths while maintaining the eccentric speaker layout for assembly convenience.
Solution Approach 2:
Different portions of the sound hole are positioned at different distances from the speaker module, with each portion having optimized sound channel characteristics. The first sound hole is positioned closer to the speaker module while the second and third sound holes are positioned farther away, creating local variations in sound transmission paths to achieve uniform overall sound output.
2Shape
If the sound hole is aligned at the center of the electronic device, then the design symmetry is improved, but the sound transmission uniformity deteriorates due to varying distances from the speaker module
Solution Approach 1:
The centrally aligned sound hole is segmented into multiple sound holes (first, second, third sound holes) positioned at different radial distances from the speaker module. This segmentation allows the overall symmetric design to be maintained while creating varied sound transmission paths that compensate for the eccentric speaker position.
Solution Approach 2:
The sound transmission problem is solved by transitioning from a single-point sound hole to a distributed array of sound holes in different spatial dimensions. The sound holes are positioned at different distances and angles, creating a three-dimensional sound transmission network that achieves uniform sound output despite the two-dimensional eccentric layout.
