Equalizer Gain Synchronization Across Multiple Frequency Bands
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional equalizers lack a method to synchronously adjust gain values across multiple frequency bands, limiting the ability to uniformly enhance or reduce audio effects.
Innovation Solution
An electronic device with a screen, memory, and processor that receives an adjusting command to modify gain values stored in the memory, allowing synchronous adjustment of gain values across multiple frequency bands, enabling the creation of a new equalizer with equimultiple changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If gain values are adjusted individually at single frequency bands, then user control over specific frequency ranges is improved, but the ability to uniformly adjust audio effects across multiple frequency bands deteriorates
Solution Approach 1:
The patent implements multiple adjustment modes that allow the equalizer to perform different functions: individual frequency band adjustment for precise control, and synchronized multi-band adjustment for uniform audio effect modification. This multi-functional approach resolves the contradiction by providing both specialized and comprehensive adjustment capabilities within the same system.
Solution Approach 2:
The equalizer dynamically switches between different adjustment modes based on user needs. The system can transition from static individual band adjustment to dynamic synchronized adjustment across multiple bands, allowing the device to adapt its behavior to achieve both precise control and uniform audio effect modification as required.
2Ease of operation
If multiple pre-installed modes are provided for equalizer adjustment, then ease of use is improved, but the ability to customize synchronous gain value adjustments deteriorates
Solution Approach 1:
The system provides pre-installed modes for users who prefer ready-made configurations, while simultaneously enabling users to create and save custom equalizer settings. This self-service approach allows users to benefit from both convenience and customization, resolving the contradiction between ease of use and adaptability.
Solution Approach 2:
Pre-installed equalizer modes are provided in advance for common audio adjustment scenarios, eliminating the need for users to manually configure multiple frequency bands. This preliminary preparation maintains ease of use while the system remains adaptable to custom configurations when needed.
3Manufacturing precision
If gain values at multiple frequency bands are adjusted synchronously in an equimultiple way, then consistency of audio effect across frequency bands is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple gain value adjustments into a single synchronized operation. By merging the adjustment of multiple frequency bands into one equimultiple adjustment action, the system achieves consistent audio effects across bands while presenting a simplified user interface that does not expose the underlying complexity of coordinating multiple parameters simultaneously.
