Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The quality of a user's listening experience is often diminished by variables in the device's environment, such as geometry, user location, and ambient noise, which existing audio playback systems fail to account for.
Innovation Solution
An audio playback system that adjusts physical attributes like the orientation of sound-emitting components, sound wave reflection, and sound wave passageway geometry based on detected environmental attributes, using sensors and actuators to enhance sound wave emission and reception.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If audio playback is performed in a fixed environment, then the audio output component can be designed with simple structure, but the listening experience quality deteriorates due to environmental variables
Solution Approach 1:
The patent applies dynamics by making the audio output component physically adjustable rather than fixed. The component can change its physical attributes (orientation, position, geometry) in response to environmental conditions detected by sensors, allowing the system to adapt to different listening environments and maintain high audio quality without requiring a completely complex redesign of the entire system.
Solution Approach 2:
The patent changes physical parameters of the audio output component (orientation angles, position coordinates, geometric dimensions) based on environmental attribute data. By adjusting these parameters dynamically, the system compensates for environmental variables such as room acoustics, user position, and ambient noise, thereby improving listening experience quality without adding excessive system complexity.
2Ease of operation
If the audio output component orientation is fixed, then the device structure remains simple, but the sound wave propagation is suboptimal in varying environmental conditions
Solution Approach 1:
The patent implements feedback by using sensors to detect environmental attributes (such as room geometry, user position, ambient noise levels) and using this information to automatically adjust the audio output component's orientation and position. This closed-loop control system optimizes sound wave propagation without requiring manual intervention, thereby improving ease of operation while managing device complexity through automated control.
3Reliability
If sound wave reflection components are positioned statically, then the device assembly is simplified, but the audio quality diminishes due to unaccounted environmental acoustics
Solution Approach 1:
The patent makes the sound wave reflection components dynamically positionable rather than statically fixed. These components can adjust their positions based on environmental acoustic characteristics detected by sensors, allowing optimization of sound reflection patterns for different environments. This dynamic adjustment improves audio quality while the modular design helps manage assembly complexity.
