Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices face efficiency deterioration when receiving high-quality audio signals due to high power consumption, and receiving low-quality audio signals results in poor performance for applications requiring high-quality audio, such as voice recognition.
Innovation Solution
An audio converting method and device that selectively receive or output audio signals based on the state of the electronic device or executed application, switching between differential and single-ended modes to optimize power usage and sound quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the electronic device receives a high-quality audio signal, then the audio quality is improved, but the power consumption increases
Solution Approach 1:
The patent applies dynamics by making the audio receiving mode adjustable and switchable between different states (high-quality differential mode and low-power single-ended mode) based on real-time device conditions. The processor dynamically selects the appropriate mode according to battery level, current operations, and audio quality requirements, allowing the system to adapt its power consumption and performance characteristics flexibly rather than being fixed in one state.
Solution Approach 2:
The patent implements parameter changes by modifying the audio signal receiving parameters - specifically switching between differential mode (with higher power consumption but better quality) and single-ended mode (with lower power consumption but acceptable quality). This parameter switching allows the system to optimize the balance between audio quality and power consumption based on actual device state and application needs.
2Use of energy by moving object
If the electronic device receives a low-quality audio signal, then the power consumption is reduced, but the audio quality deteriorates
Solution Approach 1:
The patent applies partial action by using the single-ended mode which provides sufficient audio quality for basic operations without requiring the full performance of differential mode. This partial action approach allows the device to consume less power while still meeting the audio quality requirements for common tasks like voice wake-up or simple voice commands, reserving the high-quality differential mode only when truly necessary.
3Adaptability or versatility
If the electronic device executes multiple functions simultaneously (audio receiving and image providing), then the functionality is improved, but the power consumption increases
Solution Approach 1:
The patent applies dynamics by making the audio receiving mode adaptable to the current operational context. When the device is executing multiple functions simultaneously (such as providing images while receiving audio), the processor can dynamically switch to single-ended mode for audio receiving, thereby reducing overall power consumption while maintaining the ability to perform multiple functions. This dynamic adaptation allows the system to balance functionality with power efficiency.
