Audio Path Switching Between Wearables and Screen Mirroring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices face challenges in seamlessly switching audio paths when connecting to both wearable devices and external electronic devices for screen mirroring, leading to asynchronous audio output and disrupted user experiences.
Innovation Solution
The electronic device establishes a first connection with a wearable device for audio output and a second connection with an external device for screen mirroring, using different communication circuits, and automatically switches the audio path by transmitting address information to establish a direct connection between the wearable and external devices, ensuring synchronized audio output.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electronic device establishes separate connections for audio output and screen mirroring using different communication circuits, then connection stability is improved, but device complexity increases
Solution Approach 1:
The patent divides the communication system into separate communication circuits: one dedicated to audio output (e.g., Bluetooth) and another to screen mirroring (e.g., Wi-Fi). This segmentation allows each circuit to operate independently with optimized protocols, improving connection stability for both functions while managing complexity through functional separation.
Solution Approach 2:
The electronic device incorporates multiple communication circuits that can serve different functions simultaneously. The first communication circuit handles audio streaming while the second handles video/screen mirroring, enabling multi-functionality without requiring a single complex communication system to handle all tasks.
2Manufacturing precision
If the audio path is switched during screen mirroring to connect wearable devices directly, then audio synchronization is improved, but control complexity increases
Solution Approach 1:
The system pre-establishes the wearable device connection and stores its address information before initiating screen mirroring. When audio path switching is needed, the external device uses the pre-stored address to directly connect to the wearable device, avoiding synchronization delays that would occur with on-the-fly connection establishment.
Solution Approach 2:
The external device acts as an intermediary that receives address information from the electronic device and uses it to establish a direct connection with the wearable device. This intermediary role simplifies the overall control complexity by centralizing the switching logic in one device rather than requiring complex coordination between multiple devices.
3Speed
If address information is transmitted to establish direct connection between wearable and external devices, then connection speed is improved, but information security risks increase
Solution Approach 1:
Address information is transmitted and stored in advance during the initial connection phase, before any audio path switching occurs. This preliminary exchange of address information enables rapid connection establishment later without requiring real-time authentication, thus improving speed while maintaining security through pre-validated connection parameters.
