Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing audio processing systems in vehicles, such as car HiFi systems, require manual equalization by users, which can be inconvenient and may not maintain the natural sound characteristics of audio content due to lack of automated adjustment for varying acoustic environments.
Innovation Solution
A device and method for processing audio data using a mid-frequency filter unit that selectively scales amplitudes of different frequency sub-components to maintain original amplitude relations, allowing for automated equalization and improved sound quality, particularly in vehicle environments with unique acoustics.

Engineering Contradiction Analysis
1Ease of operation
If manual equalization is used in car HiFi systems, then users can adjust audio characteristics, but the operation convenience deteriorates and the original sound characteristics may not be preserved
Solution Approach 1:
The system automatically performs equalization by analyzing the audio signal and adjusting frequency components without user intervention. The device serves itself by detecting amplitude relations between frequency sub-components and applying appropriate filtering to maintain natural sound characteristics while improving operation convenience.
2Ease of operation
If automated equalization is implemented, then operation convenience improves, but the complexity of the device increases
Solution Approach 1:
The audio frequency spectrum is segmented into different sub-components, with specific focus on mid-frequency ranges. The equalization process is divided into identifying amplitude relations between sub-components and applying selective filtering, simplifying the overall device complexity while maintaining automated functionality.
Solution Approach 2:
The system changes parameters by scaling amplitudes of frequency sub-components based on detected amplitude relations. By dynamically adjusting these parameters, the device achieves automated equalization without requiring complex manual intervention mechanisms.
3Manufacturing precision
If amplitude scaling is applied to frequency sub-components, then sound quality improves, but the risk of distorting original sound characteristics increases
Solution Approach 1:
The system carefully controls parameter changes by scaling amplitudes of frequency sub-components based on their original amplitude relations. This ensures that while sound quality improves through equalization, the fundamental character of the original sound is preserved by maintaining proportional relationships between different frequency components.
