Automatic Playback Volume Sync From User Listening History
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless audio playback devices require manual volume adjustments by users to match their playback volume to personal preferences, leading to complex operations and diminished user experience.
Innovation Solution
A method for automatically adjusting the playback volume of a terminal device based on a user's habit by detecting a connection to another device and sending a volume adjustment message to match the playback volume to a previously used setting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual volume adjustment is required, then the playback volume can be customized to user preference, but the operation complexity increases and user experience deteriorates
Solution Approach 1:
The system performs preliminary action by automatically obtaining the volume value from the second electronic device before the connection to the first electronic device is established. The volume adjustment message is prepared in advance with the retrieved volume value, so that when the connection is established, the volume is already adjusted to the expected level without requiring manual user input or complex adjustment procedures.
2Ease of operation
If automatic volume adjustment is implemented, then operational complexity is reduced, but the system complexity increases
Solution Approach 1:
The system introduces an intermediary mechanism in the form of a volume adjustment message that carries volume value information from the terminal device to the first electronic device. This intermediary message enables automatic volume adjustment without requiring direct complex interaction between the devices, simplifying the overall system architecture while achieving the desired automatic adjustment functionality.
3Ease of operation
If volume adjustment based on historical connection data is used, then user comfort is improved, but the requirement for data storage and processing increases
Solution Approach 1:
The system extracts only the essential volume value information from the historical connection data of the second electronic device, rather than storing or processing complete connection records. By taking out just the volume value parameter that is needed for adjustment, the system minimizes data storage and processing requirements while still achieving the goal of automatic volume adjustment based on user habits.

AI summary
This application relates to the terminal field, and provides a volume adjustment method and a terminal device. According to the volume adjustment method and the terminal device, a playback volume may be automatically adjusted, a playback volume may be automatically adjusted, a user does not need to manually adjust the playback volume, and a requirement of the user for comfort can be met. This achieves effect of reducing complexity of an operation and improving user experience. The method includes: The terminal device obtains a first volume value in response to detecting that the terminal device establishes a communication connection to a first electronic device, where the first volume value is a volume value that conforms to a use habit of the user when the user uses a second electronic device, and the second electronic device is an electronic device that had been connected to the terminal device; and the terminal device sends a volume adjustment message to the first electronic device, where the volume adjustment message carries first volume value information for indicating the first electronic device to adjust a playback volume to a playback volume corresponding to the first volume value.
