Smart Device Dual Speaker Audio Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional smart devices like smart glasses and AR/VR devices operate in a single playback mode, failing to meet diverse user needs across different application scenarios in terms of audio effects and privacy, limiting their applicability and user experience.
Innovation Solution
A smart device with a supporting part and a moving part, featuring a first speaker on the supporting part and a second speaker on the moving part, employs a control method that receives an audio signal, determines the application scenario, processes the signal according to a target processing manner, and controls the speakers to output the processed audio signal, including frequency division processing for entertainment scenarios and selective output for call scenarios.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single playback mode is used in smart devices, then the device structure remains simple, but the device cannot meet diverse user needs in different application scenarios
Solution Approach 1:
The audio output system is segmented into multiple independent playback modes (first playback mode and second playback mode), each optimized for specific application scenarios. The first speaker and second speaker are segmented to handle different frequency ranges in the first playback mode, while in the second playback mode, only the second speaker is used for privacy-sensitive scenarios. This segmentation allows the device to adapt to different scenarios without requiring a completely different hardware architecture.
Solution Approach 2:
The playback mode is made dynamic and switchable between different modes based on the application scenario. The system can dynamically select between the first playback mode (using both speakers for entertainment) and the second playback mode (using only the second speaker for calls), allowing the device to adapt its behavior to different usage contexts without physical reconfiguration.
2Manufacturing precision
If frequency division processing is applied to audio signals, then audio effects quality is improved, but processing complexity increases
Solution Approach 1:
Frequency division processing is applied locally to specific audio signals based on the playback mode. In the first playback mode, the audio processing module performs frequency division processing on the audio signal to generate first audio signals and second audio signals for different frequency ranges. In the second playback mode, frequency division processing is not applied, simplifying the processing pipeline. This local application of processing complexity only where needed improves audio quality without unnecessarily complicating all processing paths.
