Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in changing the audio signal path to an external electronic device without prior knowledge of the device's name or operation menu navigation.
Innovation Solution
An electronic device detects an electromagnetic signal from nearby external devices and automatically identifies them, allowing for seamless changes in the audio signal path based on the identified device information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual menu navigation is used to change audio signal path, then device control precision is improved, but operation complexity and time consumption increase
Solution Approach 1:
The system performs preliminary detection of external electronic devices and pre-configures audio signal paths before user interaction. When a user approaches with an external device, the system automatically detects it and establishes the audio connection in advance, eliminating the need for manual menu navigation and reducing operation time.
Solution Approach 2:
The system enables self-service operation by automatically detecting external electronic devices and configuring audio signal paths without requiring user intervention in the settings menu. The device autonomously identifies compatible external devices and establishes audio connections based on detected information, allowing users to simply activate functions without manual configuration.
2Ease of operation
If automatic detection is implemented, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The system uses a universal detection mechanism that can identify various types of external electronic devices (headphones, speakers, tablets, etc.) through common electromagnetic signals. The same detection and configuration framework handles multiple device types, reducing the need for device-specific complex logic while maintaining ease of operation across different scenarios.

AI summary
An electronic device and method for changing a path of an audio signal by the electronic device are provided. The method includes obtaining an electromagnetic signal (EM) signal of an external electronic device through EM sensing circuitry, identifying the external electronic device based on the obtained EM signal, changing the path of the audio signal that is output by the electronic device to be output through the external electronic device, when the identified external electronic device is capable of inputting or outputting the audio signal and is connected with the electronic device, and displaying, on a touchscreen display of the electronic device, a screen for establishing a communication connection with the external electronic device, when the identified external electronic device is capable of inputting or outputting the audio signal and is not connected with the electronic device.
