Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing smartphones struggle with capturing clear audio from distant subjects and multiple subjects, and managing microphone resources efficiently, leading to inconsistent audio volume and difficulty in selective recording.
Innovation Solution
An electronic device utilizing ultra-wide band (UWB) communication to manage audio signals by acquiring audio from nearby subjects through microphones or external devices, adjusting volume levels, and displaying audio signal magnitudes through a user interface, while enabling multi-recording by distributing audio signal processing across multiple threads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single microphone is used for audio capture, then the device structure remains simple, but audio quality deteriorates when subjects are at long distances or surrounded by noise
Solution Approach 1:
The patent combines multiple microphones into a single audio capture system, merging their inputs to achieve improved audio quality for distant or noisy subjects while maintaining manageable system complexity through integrated processing
2Reliability
If multiple microphones are used to capture audio from multiple subjects, then audio quality for multiple subjects improves, but device complexity and resource management become difficult
Solution Approach 1:
The patent segments the audio capture function by assigning different microphones to different subjects or audio sources, allowing independent control and processing of each audio stream while maintaining overall system organization
Solution Approach 2:
The patent creates a universal audio processing framework that can handle multiple microphones and subjects through a single integrated system, making the microphone resources versatile and easily manageable across different recording scenarios
3Reliability
If one application occupies the microphone resource, then that application achieves exclusive audio access, but other applications cannot use the microphone resource due to chipset restrictions
Solution Approach 1:
The patent segments the microphone resource into multiple virtual channels or streams, allowing different applications to access different segments simultaneously, thereby enabling multi-recording functionality while maintaining signal fidelity for each application
4Ease of operation
If audio volume is automatically captured without adjustment, then the capture process is simple, but users cannot identify or adjust the magnitude of input audio signals
Solution Approach 1:
The patent implements feedback by displaying the magnitude of captured audio signals to users, providing visual information about audio levels while maintaining automatic capture, thereby preventing information loss without adding manual adjustment complexity
