Audio Service Parameter Adjustment for Mobile Terminal Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile devices experience power-off or restart issues when running audio services in low-temperature or low-battery scenarios due to increased internal resistance and reduced battery output capability.
Innovation Solution
A method for adjusting audio service parameters, such as volume and sound effects, based on battery level and temperature thresholds, allowing the terminal to switch between normal and low-power modes to reduce power consumption and prevent device shutdown.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal runs audio service at high volume in low-temperature or low-battery scenario, then user experience is improved, but the terminal is powered off or restarted due to increased internal resistance and reduced battery output capability
Solution Approach 1:
The patent implements dynamic adjustment of audio service parameters based on real-time detection of battery level and temperature. The system transitions from static audio parameters to dynamic parameters that adapt to changing environmental conditions, allowing the terminal to maintain stability while preserving audio quality as much as possible under constrained conditions
Solution Approach 2:
The patent changes physical parameters of the audio service including volume level, sampling rate, and bitrate based on battery level and temperature thresholds. By adjusting these parameters dynamically, the system reduces power consumption and thermal load to prevent power-off or restart while maintaining acceptable audio service quality
2Duration of action of moving object
If the terminal maintains normal audio service parameters in low-battery scenario, then audio quality is preserved, but battery life is exhausted quickly causing power-off
Solution Approach 1:
The patent performs preliminary detection of battery level and temperature before the terminal actually powers off. By detecting these parameters in advance and proactively adjusting audio service parameters, the system extends battery life and prevents sudden power-off, allowing the terminal to continue operating longer than it would with normal parameters
Solution Approach 2:
The patent applies partial action by adjusting only the necessary audio parameters (volume, sampling rate, bitrate) rather than shutting down the entire audio service. This partial adjustment reduces power consumption sufficiently to extend battery life while maintaining basic audio functionality, achieving a balance between battery preservation and service continuity
3Illumination intensity
If the terminal increases audio volume to compensate for low-frequency reduction in low-temperature scenario, then sound output is improved, but current consumption increases causing restart
Solution Approach 1:
The patent changes multiple audio parameters simultaneously including volume, sampling rate, and bitrate based on temperature conditions. By coordinating these parameter changes rather than adjusting volume alone, the system achieves acceptable sound output quality while controlling current consumption to prevent terminal restart

AI summary
A method for adjusting a parameter of an audio service and a terminal includes obtaining, by the terminal, first information, where the first information includes at least one of a first battery level or a first temperature, and adjusting, by the terminal, a parameter of an audio service of the terminal when a first condition is met, where the first condition includes one or more of the first battery level is less than a first preset threshold or greater than a second preset threshold, or the first temperature is less than a third preset threshold or greater than a fourth preset threshold.
