Solution Overview

Problem

Users face difficulties in manually adjusting equalizer settings on audio devices to enhance their music listening experience, especially when unfamiliar with specific music genres, as not all devices allow for such adjustments and the process can be complex.

Innovation Solution

An automated system that uses processors to detect music being played, determine the genre, and adjust equalizer settings such as bass and treble based on audio characteristics, either by characterizing the sound or learning from user manual adjustments, to optimize the listening experience without user intervention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If automated equalizer adjustment is implemented, then ease of operation is improved, but device complexity increases

Engineering Contradiction:

Improveease of equalizer adjustmentVSAvoidsystem complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The system automatically detects music genre and adjusts equalizer settings without user intervention. The processor analyzes audio characteristics, identifies the music genre, and autonomously modifies equalizer parameters, allowing the system to serve itself rather than requiring manual user configuration.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical adjustment of equalizer sliders with an automated digital processing system. The processor uses algorithms to analyze audio signals and programmatically adjust equalizer settings, substituting physical user interaction with electronic automation.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If manual equalizer adjustment is required, then adaptability to user preference is improved, but ease of operation deteriorates

Engineering Contradiction:

Improveuser preference adaptationVSAvoidease of equalizer adjustment

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system incorporates feedback mechanisms where user manual adjustments are detected and stored. When the same music genre is detected again, the system recalls previous user preferences and applies appropriate equalizer settings, adapting to user taste while maintaining ease of operation through automation.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system performs preliminary analysis of music genre and pre-configures equalizer settings before the user needs them. By detecting the music genre in advance and automatically applying appropriate settings, the system prepares the optimal configuration proactively rather than requiring reactive manual adjustment.

Inventive Principle:

Principle #10Preliminary action

AI summary

Implementations generally relate to automated equalizer adjustments based on audio characteristics. In some implementations, a method includes detecting music that is being currently played on an audio device. The method further includes adjusting one or more equalizer settings of an equalizer device based at least in part on a music genre associated with the music. The method further includes outputting the music based at least in part on the adjusting of the one or more equalizer settings of the equalizer device.
