Audio Display Control for Wireless Charging Screen Shielding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The display effect of an audio device's display screen is affected when it performs wireless charging for a mobile device due to the mobile device shielding the screen.
Innovation Solution
A control method for an audio device that detects the screen placement state of a mobile device and adjusts the display content accordingly, using sensors and a microphone array to determine the placement state and adjust the display mode to optimize the display effect while charging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the mobile device is placed on the audio device for wireless charging, then the charging convenience is improved, but the display screen of the audio device is shielded and the display effect deteriorates
Solution Approach 1:
The patent uses the mobile device's own screen as an intermediary display surface. Instead of directly displaying content on the audio device's shielded screen, the system mirrors or projects the display content onto the mobile device's screen, which is positioned above the audio device during charging. This intermediary approach allows the display function to be maintained without requiring the audio device's screen to be visible.
Solution Approach 2:
The patent creates a copy of the display content from the audio device's screen and displays it on the mobile device's screen. The content mirroring function replicates visual information (such as music playback information, interface elements) and presents it through an alternative channel (the mobile device display), thereby preserving the display functionality despite the physical shielding of the original screen.
2Loss of information
If the display content is continuously shown on the audio device screen during charging, then the information display completeness is improved, but the screen shielding by mobile device causes loss of information visibility
Solution Approach 1:
The mobile device screen serves as an intermediary that receives and displays the information that would otherwise be shown on the shielded audio device screen. This transfers the information display function to an unobstructed surface, maintaining information completeness without the harmful effect of shielding.
Solution Approach 2:
The system creates a real-time copy of the display information and transmits it to the mobile device for display. This copying mechanism ensures that all information intended for display is preserved and made visible through the mobile device's unobstructed screen, eliminating the information loss caused by shielding.
3Measurement precision
If the audio device uses sensors and microphone array to detect screen placement state, then the display mode adjustment accuracy is improved, but the device complexity increases
Solution Approach 1:
The patent reuses existing sensors and microphone arrays in the audio device for multiple purposes. These components, originally designed for other functions (such as voice recognition, environmental sensing), are additionally utilized to detect the placement state of the mobile device screen. This multi-functional use avoids adding dedicated detection hardware, thereby maintaining measurement precision while limiting the increase in device complexity.
Solution Approach 2:
The audio device utilizes its own existing sensing capabilities (sensors and microphone array) to detect the screen placement state without requiring external detection devices. The system serves its own detection needs using components already present in the device, reducing the need for additional specialized hardware and keeping the system relatively simple while achieving accurate detection.
