Solution Overview
Problem
Electronic devices with flexible displays face challenges in optimizing audio signal processing when their structural form changes, leading to increased reconfiguration time and current consumption.
Innovation Solution
The electronic device includes a sensor module that determines its state and communicates directly with an audio processing module to reconfigure the audio path based on configuration information, reducing reconfiguration time and current consumption without involving the main processor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the main processor reconfigures the audio processing path when the electronic device state changes, then the audio processing can be optimized for different structural forms, but the reconfiguration time increases and current consumption increases
Solution Approach 1:
The patent divides the processor into two separate modules: a sensor processor that detects device state changes and an audio processor that handles audio signal processing. This segmentation allows the audio processor to be independently reconfigured based on state information from the sensor processor, reducing the reconfiguration time by eliminating the need for the main processor to handle both sensing and audio processing tasks sequentially.
Solution Approach 2:
The sensor processor acts as an intermediary between the device's structural state and the audio processing system. It detects state changes (such as folding or unfolding events) and transmits this information to the audio processor, which then reconfigures the audio processing path accordingly. This intermediary mechanism enables faster reconfiguration compared to direct main processor control.
2Adaptability or versatility
If the main processor reconfigures the audio processing path when the electronic device state changes, then the audio processing can be optimized for different structural forms, but the current consumption increases
Solution Approach 1:
By segmenting the processing tasks between a sensor processor (for state detection) and an audio processor (for audio signal processing), the system reduces the computational burden on the main processor. The audio processor can be reconfigured using pre-stored configuration information based on state changes, which consumes less current compared to full main processor involvement in each reconfiguration event.
Solution Approach 2:
The system pre-stores multiple audio processing path configuration information corresponding to different device states (such as folded, unfolded, intermediate states). When a state change is detected, the audio processor directly applies the pre-configured settings without requiring real-time computation by the main processor, thereby reducing current consumption during reconfiguration.
3Reliability
If the audio processing path is reconfigured based on device state changes, then high-quality audio processing is achieved for different structural forms, but the system complexity increases
Solution Approach 1:
The sensor processor and audio processor are designed as multi-functional modules that can handle multiple device states (folded, unfolded, intermediate states) using a unified architecture. The audio processor uses a standardized reconfiguration mechanism based on pre-stored configuration information, which maintains system reliability across different states without significantly increasing complexity.
