Sound Volume Operation Device with Color-Changing Illumination Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sound volume operation devices for DJ performances lack effective visual feedback for output sound volume levels in frequency bands, as they either display gain settings rather than actual output levels or only indicate volume changes without clear visualization.
Innovation Solution
A sound volume operation device with adjustable amplifiers and illuminators that change color based on detected output sound volume levels, allowing operators to visually check the output sound volume levels in high, medium, and low frequency bands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the mixer includes a large number of operation buttons and knobs, then various equalizer functions can be provided, but the display area of the level meter cannot be ensured
Solution Approach 1:
The patent applies color-changing illumination to indicate different sound volume levels in frequency bands. The illuminator changes color (e.g., green for normal, yellow for high, red for peak levels) to provide visual feedback about output sound volume levels, replacing the need for large display areas with compact color-coded indicators around the equalizer knobs.
2Device complexity
If no display indicating adjusted sound volume is provided, then the device structure remains simple, but the operator cannot visually check the equalizer adjustment states
Solution Approach 1:
The patent implements visual feedback through illuminators that change color based on detected output sound volume levels. The output level detector continuously monitors the amplified signal and feeds back visual information through color-changing illumination, allowing operators to see the effect of their equalizer adjustments in real-time without adding complex display systems.
3Device complexity
If illumination displays only gain setting values, then the illumination system remains simple, but it cannot show actual output sound volume levels
Solution Approach 1:
The patent introduces an output level detector as an intermediary component that bridges the gap between the simple illumination system and the need for accurate output level indication. The detector monitors the actual amplified signal and provides this information to the illuminator, enabling color-coded representation of true output sound volume levels rather than just gain settings.
