Mobile Terminal Sound Effect Parameter Adjustment

Solution Overview

Problem

Mobile terminals face challenges in managing multiple sound effects added to audio files, leading to inconsistent playback experiences, as different applications can apply various sound effects, resulting in a negative impact on the overall playing effect.

Innovation Solution

A method is implemented in mobile terminals to acquire and adjust sound effect parameters, determining if they match an initial setting, and if not, adjusting them to fall within a preset range to eliminate conflicts and enhance playback quality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple application programs add different sound effects to audio files, then the audio playback functionality is enhanced with various effects, but the consistency and quality of playback experience deteriorates due to conflicting sound effects

Engineering Contradiction:

Improveaudio playback functionalityVSAvoidplayback experience consistency

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent merges multiple sound effect parameters from different application programs into a unified sound effect parameter. The processing unit acquires sound effect parameters from multiple applications, combines them according to preset rules (such as weighting different parameters by importance), and outputs a single integrated sound effect parameter that is applied to the audio file, thereby ensuring consistent playback experience across different applications.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent creates a universal sound effect processing mechanism that works across different application programs. The processing unit serves multiple applications by acquiring their individual sound effect parameters, integrating them through a common algorithm, and providing a unified output that maintains playback consistency regardless of which application is used.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If multiple sound effects are added to an audio file by different applications, then various playback effects are achieved, but the overall playing effect deteriorates due to sound effect conflicts

Engineering Contradiction:

Improvesound effect varietyVSAvoidplaying effect quality

Core Design Contradiction:

Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The patent merges multiple sound effect parameters from different application programs into a unified sound effect parameter. The processing unit acquires sound effect parameters from multiple applications, combines them according to preset rules (such as weighting different parameters by importance), and outputs a single integrated sound effect parameter that is applied to the audio file, thereby ensuring consistent playback experience across different applications.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent transforms multiple sound effect parameters into a single integrated parameter through mathematical operations. The processing unit changes the state of multiple parameters by applying weighting coefficients and aggregation algorithms, converting diverse sound effect settings into a unified parameter set that maintains audio quality while incorporating effects from multiple sources.

AI summary

A sound effect parameter adjustment method, and a mobile terminal. The method comprises: obtaining a sound effect parameter of a mobile terminal and determining the sound effect parameter as an initial sound effect parameter; detecting, when playing an audio file by audio playback software, whether a playback sound effect parameter of the audio file is consistent with the initial sound effect parameter; if it is detected that the playback sound effect parameter of the audio file is not consistent with the initial sound effect parameter, determining whether the playback sound effect parameter of the audio file falls within a preset sound effect parameter interval; and if not, adjusting the sound effect parameter to be within the sound effect parameter interval.
