Audio Device Identification via Characteristic Data Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for identifying audio devices in mobile devices often result in noise when earphones are inserted, affecting the user's auditory experience.
Innovation Solution
A method involving a mobile device that monitors the insertion or removal of an audio device, records audio data, and determines if it is an audio smart key device by identifying characteristic data, thereby preventing noise by ensuring only audio smart key devices receive data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mobile device sends audio data to the audio device, then the audio smart key device can receive and process the data, but noise is generated when an earphone is inserted, affecting user auditory experience
Solution Approach 1:
The mobile device performs preliminary identification of the audio device type before sending audio data. It monitors the audio data returned by the device and determines whether it is an audio smart key device based on characteristic data patterns, ensuring that data is only sent to appropriate devices and preventing noise generation in earphones
Solution Approach 2:
The system uses feedback from the audio data returned by the connected device to identify its type. The mobile device analyzes the characteristic data in the returned audio stream to determine whether the connected device is an audio smart key device or an earphone, and adjusts its behavior accordingly to prevent noise
2Measurement precision
If the mobile device monitors and records audio data to identify the audio device type, then accurate identification can be achieved, but the system complexity increases
Solution Approach 1:
The patent uses audio data as an intermediary to identify the audio device type. Instead of requiring complex hardware identification mechanisms, the system analyzes the audio data returned by the connected device, which naturally contains characteristic patterns that reveal the device type. This approach achieves accurate identification while keeping the system relatively simple
Solution Approach 2:
The system creates a simplified model of device identification by analyzing copies of audio data rather than requiring direct hardware inspection. The characteristic data patterns in the audio stream serve as a fingerprint to identify device type, avoiding the need for complex physical identification mechanisms

AI summary
A method for identifying an audio device, in which a mobile device starts to monitor pull out or insert of an audio device, when the mobile device connects the audio device, the mobile device starts to record, the audio device is identified as an audio smart key device in the case that characteristic data is received in a first preset time, and data is sent to the audio smart key device; turns off recording in the case that the characteristic data is not received in the first preset time; the audio smart key device is powered on and initialized, it sends audio data to the mobile device, subsequently, if the audio smart key device receives data sent from the mobile device in a second preset time, it processes the data; if the audio smart key device does not receive the data sent from the mobile device, the audio smart key device turns off; when the mobile device disconnects the audio device, the mobile device turns off recording and the audio device turns off. According to the present invention, a mobile device can identify a type of an audio device which is inserted into the mobile device, the mobile device sends data after ensuring that the audio device is an audio smart key device, thus, the method can prevent from any noise in the earphone, so the users can feel better.
