Adaptive Guitar Signal Distortion for Music Speaker Amplification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional guitar amplifiers produce inherent distortion that limits their use to electric guitar signals, while music amplifiers fail to replicate the unique distortion effect of guitar amplifiers, necessitating separate devices for different types of audio signals, which complicates usage scenarios.
Innovation Solution
An audio processing method and device that applies linear and nonlinear distortion processing to electric musical instrument signals, combined with equalization and effect processing, allowing output to a conventional music speaker, and supports multiple amplification modes for both instrument and music signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If guitar amplifiers use vacuum tube circuits to produce unique distortion effects, then the guitar timbre is improved, but the device cannot amplify music signals other than electric guitar signals
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting distortion parameters (amount of distortion, type of distortion) based on the input signal type. The system identifies whether the input is an electric guitar signal or music signal and applies different distortion parameter sets accordingly, allowing the same amplifier to maintain guitar timbre quality while expanding versatility to handle music signals.
Solution Approach 2:
The patent implements dynamics through real-time adaptive distortion processing. The distortion characteristics are not fixed but dynamically adjusted based on signal analysis. The system continuously monitors the input signal and modifies distortion parameters in real-time, enabling the amplifier to adapt its behavior between guitar and music signal modes.

If separate amplifiers are used for electric guitar signals and music signals, then the signal quality is improved, but the device complexity increases
Solution Approach 1:
The patent applies universality by designing a single amplifier capable of handling both electric guitar signals and music signals. The amplifier incorporates multi-mode distortion processing that can adapt to different signal types, eliminating the need for separate dedicated amplifiers for each signal type while maintaining signal quality.
Solution Approach 2:
The patent implements dynamics through real-time adaptive distortion processing. The distortion characteristics are not fixed but dynamically adjusted based on signal analysis. The system continuously monitors the input signal and modifies distortion parameters in real-time, enabling the amplifier to adapt its behavior between guitar and music signal modes.
