Dual Mode Ported Speaker Enclosure for Adaptive Acoustic Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing audio systems for wearable devices are inadequate as they typically operate in only one mode, failing to adapt to different applications that require varying levels of sound pressure and radiation control, such as private versus public spaces or scenarios with multiple devices, which can lead to suboptimal user experience due to interference or privacy concerns.
Innovation Solution
An audio system for wearable devices that can operate in multiple modes by configuring its enclosure and port states, switching between sealed and ported configurations based on detected applications or signals, utilizing a digital signal processor and mechanical systems to adjust settings, and incorporating feedback sensors to manage spatial audio and reduce interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If sealed enclosure is used, then sound pressure level is improved, but radiation control deteriorates
Solution Approach 1:
The patent applies the dynamics principle by making the enclosure configuration changeable between sealed and ported states. A mechanical system with movable walls or adjustable partitions allows the enclosure to dynamically reconfigure its internal volume and port openings based on the audio application requirements, enabling optimization of both sound pressure level and radiation control as needed
2Ease of manufacture
If ported enclosure is used, then radiation control is improved, but output level deteriorates
Solution Approach 1:
The patent applies the dynamics principle by making the enclosure configuration changeable between sealed and ported states. A mechanical system with movable walls or adjustable partitions allows the enclosure to dynamically reconfigure its internal volume and port openings based on the audio application requirements, enabling optimization of both sound pressure level and radiation control as needed
