Solution Overview

Problem

Existing electronic equipment lacks accuracy in automatically adjusting audio and video information parameters based on environmental noise, often leading to misjudgments and unnecessary volume adjustments.

Innovation Solution

The method involves collecting environmental audio information, performing noise detection to identify target noise scenarios, and processing multimedia parameters such as volume or playback speed only when the noise scenario is detected, using techniques like echo cancellation and energy threshold analysis to improve accuracy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If electronic equipment automatically adjusts audio and video parameters based on environmental noise, then the adaptability to environment is improved, but the measurement precision of noise detection deteriorates leading to misjudgments

Engineering Contradiction:
Improveadaptability to environmentVSAvoidnoise detection accuracy
Core Design Contradiction:
Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The patent segments environmental audio into multiple frequency bands (low, mid, high frequencies) and analyzes energy distribution in each band separately. This segmentation allows precise identification of target noise scenarios by comparing energy ratios across bands, resolving the contradiction by enabling accurate detection through divided analysis rather than overall noise level detection.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent changes detection parameters by analyzing energy distribution across different frequency bands rather than using a single noise level threshold. It dynamically adjusts detection criteria based on energy ratios between frequency bands, which improves measurement precision while maintaining environmental adaptability.

Inventive Principle:
Principle #35Parameter changes

2Speed

If electronic equipment performs continuous noise detection and parameter adjustment, then the responsiveness to environment is improved, but the loss of time for unnecessary adjustments increases

Engineering Contradiction:
Improveresponsiveness to environmentVSAvoidtime for unnecessary adjustments
Core Design Contradiction:
SpeedVSLoss of time

Solution Approach 1:

The patent performs preliminary analysis by segmenting audio into frequency bands and establishing energy ratio thresholds before making adjustment decisions. This preliminary action filters out non-target noise scenarios, reducing unnecessary adjustments and time loss while maintaining quick responsiveness to actual target noise.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements feedback mechanisms by continuously monitoring energy distribution across frequency bands and comparing against thresholds. This feedback system enables rapid response to genuine noise changes while avoiding unnecessary adjustments, optimizing both responsiveness and time efficiency.

Inventive Principle:
Principle #23Feedback
