Audio Routing Segmentation for Simultaneous Media and Call Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable electronic devices connected to external audio devices often route both media playback sounds and call sounds through the external device, causing user annoyance during media playback and phone calls.
Innovation Solution
An electronic device with a processor and memory configured to manage audio output paths using multiple communication protocols, allowing for separate routing of audio signals to internal and external devices based on application attributes and user preferences, enabling simultaneous media playback and call handling without overlapping audio outputs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If audio data is routed through an external audio device during media playback, then audio output quality is improved, but call sounds cannot be output separately causing user annoyance
Solution Approach 1:
The patent segments audio output into multiple independent channels: media playback audio is routed through the external audio device while call audio is routed through the internal speaker. This segmentation allows different audio types to be handled separately, resolving the contradiction between external audio quality and call handling capability.
Solution Approach 2:
The patent introduces a new dimension of audio routing control by implementing separate output paths for different audio sources. Instead of a single unified audio output, the system creates multiple audio channels that can be independently directed to different output devices, enabling simultaneous media playback through external device and call audio through internal speaker.
2Device complexity
If multiple audio sources are output through the same external device, then device connectivity is simplified, but audio mixing causes user annoyance
Solution Approach 1:
The patent segments the audio routing system into distinct paths for different audio sources. Media playback audio and call audio are separated into different routing channels, with media audio directed to the external audio device and call audio directed to the internal speaker. This segmentation simplifies the overall system by providing clear, dedicated paths for each audio type.
Solution Approach 2:
The patent implements dynamic audio routing that automatically adjusts based on the active audio source. The system dynamically switches between different output configurations: when media playback is active, audio routes through the external device; when a call is active, audio routes through the internal speaker. This dynamic behavior provides ease of operation without requiring manual configuration.
Data Source
AI summary
A method for communicating data by an electronic device is provided. The method includes transmitting a signal including audio/video (A/V) data to a first external electronic device through a first communication module, while connected with the first external electronic device, generating data or a signal unrelated to the A/V data or receiving the data or signal unrelated to the A/V data from an external electronic device other than the first external electronic device, and providing an audio or a video through a display or an embedded sound device based on at least a portion of the data or the signal unrelated to the A/V data or transmitting the at least a portion of the data or the signal unrelated to the A/V data to a second external electronic device through a second communication module.
