Audio Volume Control for Multi-Device Connectivity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices struggle to control the output volume of audio content when connected to multiple external devices, especially when some devices support media volume synchronization and others do not, leading to inconsistent and often lower-than-intended volume levels.
Innovation Solution
An electronic device equipped with an audio module, a communication module, and a processor that identifies connections with multiple external devices, determines their attributes, and transmits audio data with specified volume levels to each device based on its attributes, thereby maintaining a user-intended volume level without requiring the media volume synchronization function to be switched off.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the media volume synchronization function is turned on to synchronize volume across external devices, then volume consistency is improved, but individual volume control capability deteriorates
Solution Approach 1:
The patent implements dynamic switching between media volume synchronization mode and independent volume control mode based on user selection. The system allows the electronic device to adapt its volume control behavior dynamically - when synchronization is needed, it enables media volume sync; when individual control is needed, it disables sync. This resolves the contradiction by making the system flexible rather than fixed.
2Ease of operation
If the media volume synchronization function is switched off to enable individual volume control, then volume control flexibility is improved, but output volume level deteriorates
Solution Approach 1:
The patent changes the volume parameter transmission mode based on the selected control mode. When independent volume control is enabled, the system transmits both the electronic device's volume level and the external device's volume level to the audio module, which then calculates and transmits the appropriate audio data volume level. This parameter adjustment ensures that even without media volume synchronization, the output volume remains at the user-intended level by compensating through parameter modification.
3Adaptability or versatility
If media volume synchronization is used with multiple external devices, then volume统一管理 is improved, but device compatibility deteriorates
Solution Approach 1:
The patent applies different volume control strategies to different external devices based on their individual attributes. The audio module identifies whether each connected external device supports media volume synchronization, and then applies the appropriate control method - synchronized control for supporting devices and independent control for non-supporting devices. This local differentiation resolves the compatibility issue while maintaining overall volume management capability.
