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 adequately address.
Innovation Solution
Adjusting physical attributes of an audio playback system based on detected environmental attributes, including orientation, position, and geometry, using sensors and actuators to enhance sound wave reflection and emission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the audio playback system uses fixed physical attributes, then the device structure is simple, but the listening experience quality deteriorates due to environmental variables
Solution Approach 1:
The patent implements dynamic adjustment of physical attributes including the orientation of the audio output component, position of sound wave reflecting components, geometry of sound wave passageways, and tautness of the audio output component membrane. These attributes are continuously adjusted based on detected environmental conditions such as ambient noise levels, room geometry, and user location, transforming the previously static system into an adaptive one that maintains optimal listening experience quality across varying environments.
Solution Approach 2:
The system employs environmental sensors to detect ambient conditions and feeds this information back to the control system, which then adjusts the physical attributes of the audio playback system accordingly. This closed-loop feedback mechanism enables the system to automatically adapt to environmental variables such as noise levels and room acoustics, resolving the contradiction between maintaining high listening experience quality and avoiding excessive device complexity.
2Reliability
If the audio output component orientation is adjusted to optimize sound emission, then the listening experience improves, but the device complexity increases
Solution Approach 1:
The orientation of the audio output component is made dynamically adjustable through actuators that reposition the component based on detected user location and environmental conditions. This dynamic repositioning capability allows the system to optimize sound emission quality for different listening scenarios without requiring a completely redesigned device structure, as the same component can be oriented differently to suit various environments.
3Reliability
If sound wave reflecting components are added to enhance audio quality, then the listening experience improves, but the device complexity and size increase
Solution Approach 1:
The patent integrates sound wave reflecting components that serve multiple functions: they enhance audio quality by managing sound reflections, and simultaneously function as part of the device's structural housing or aesthetic design elements. This multi-functionality approach allows the system to improve audio quality without proportionally increasing device complexity, as the reflecting components are incorporated into existing structural elements rather than adding entirely separate components.
