Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing audio playback devices struggle to dynamically adjust sound effects in response to changes in user distance, angle, and ambient noise, requiring manual user intervention for optimal listening experience.
Innovation Solution
An electronic device collects ambient audio using a connected device to determine the listening sound effect and adjusts playback parameters to maintain optimal sound quality, regardless of distance, angle, or noise changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the sound effect is preset before delivery or manually set by the user, then the device structure remains simple, but the listening sound effect deteriorates when distance, angle, or ambient noise changes
Solution Approach 1:
The patent implements a feedback mechanism where the audio playback device collects ambient sound through a connected electronic device, evaluates the listening sound effect based on collected audio data, and automatically adjusts audio parameters to maintain optimal sound quality. This closed-loop feedback system resolves the contradiction by dynamically adapting to environmental changes without requiring complex manual intervention from the user.
Solution Approach 2:
The sound effect adjustment system operates autonomously by automatically collecting ambient sound, evaluating the listening sound effect, and adjusting audio parameters without requiring user intervention. The system serves itself by selecting the connected electronic device with the highest possibility of being carried near the audio playback device, performing evaluation and adjustment tasks independently to maintain optimal sound quality.
2Reliability
If the user manually adjusts the sound effect to compensate for environmental changes, then the listening sound effect can be maintained, but the ease of operation deteriorates due to cumbersome adjustments
Solution Approach 1:
The system automatically performs sound effect evaluation and adjustment without requiring user intervention. It autonomously selects the appropriate connected electronic device, collects ambient sound data, evaluates the listening sound effect, and adjusts audio parameters, thereby maintaining reliable sound quality while eliminating cumbersome manual operations.
Solution Approach 2:
The patent introduces an intermediary evaluation mechanism that acts between the ambient environment and the user. The system uses the connected electronic device as a mediator to collect ambient sound and evaluates the listening sound effect objectively, replacing subjective manual adjustment with an automated intermediary assessment and control system.
3Reliability
If audio parameters are dynamically adjusted based on ambient sound collection, then the listening sound effect is maintained, but the use of energy increases due to continuous evaluation and adjustment
Solution Approach 1:
The patent implements dynamic audio parameter adjustment that adapts to changing environmental conditions. The system continuously evaluates the listening sound effect by collecting ambient sound through the connected electronic device and automatically adjusts audio parameters in real-time, maintaining reliable sound quality while managing energy consumption through on-demand evaluation and adjustment based on environmental changes.
4Measurement precision
If the system selects the connected electronic device with the highest possibility that the user carries it near the audio playback device, then the measurement precision of listening sound effect improves, but the device complexity increases
Solution Approach 1:
The patent changes the selection parameter from arbitrary or manual device selection to probability-based selection. The system evaluates the possibility that the user carries each connected electronic device near the audio playback device and selects the device with the highest probability. This parameter change improves measurement precision by choosing the most likely evaluation position while managing complexity through automated probability assessment.

AI summary
This application discloses a sound effect adjustment method and an electronic device. In the method, a first electronic device that plays first audio may indicate a second electronic device to start up an audio collection apparatus, to collect an ambient sound and obtain ambient audio. The second electronic device is an electronic device with a highest possibility that a user carries the electronic device. Based on the first audio and the ambient audio, the first electronic device may determine a difference between a listening sound effect of the first audio at a location of the second electronic device and an optimal sound effect. The first electronic device may adjust an audio parameter for playing the first audio, so that the listening sound effect of the first audio at the location of the second electronic device reaches the optimal sound effect.
