Vehicle Receiver Dynamic Equalizer Media Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle sound systems lack the ability to dynamically adjust equalizer settings based on the type of media being played, leading to suboptimal audio quality for different genres and sources, as current settings are typically fixed and not tailored to specific music or noise environments.
Innovation Solution
A system where a mobile device generates a sound profile based on media identifying information, adjusting the vehicle's receiver settings, including equalizer and amplifier settings, to optimize audio quality by communicating with a tuning server and audio server to retrieve baseline profiles and applying adjustments based on vehicle noise profiles and user preferences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed amplifier settings are used in vehicle sound systems, then device complexity is reduced and ease of operation is improved, but adaptability to different media types and sound quality deteriorate
Solution Approach 1:
The patent implements dynamic equalizer settings that automatically adjust amplifier parameters based on the detected media type. The system transitions from fixed settings to dynamic adaptation by analyzing media identifying information and retrieving corresponding sound profiles from a tuning server, allowing the equalizer to adapt its characteristics in real-time according to the playback content.
Solution Approach 2:
The system employs feedback mechanisms by continuously monitoring media identifying information from the audio source and using this information to automatically adjust equalizer settings. The receiver communicates with a tuning server to obtain optimized sound profiles based on the detected media type, creating a closed-loop system that adapts settings based on actual playback conditions.
2Reliability
If manual adjustment of equalizer settings is required for different genres, then sound quality can be optimized, but ease of operation deteriorates and loss of time increases
Solution Approach 1:
The system performs self-service by automatically detecting the media type through media identifying information and autonomously adjusting the equalizer settings without requiring user intervention. The receiver automatically communicates with the tuning server to retrieve appropriate sound profiles and applies them based on the detected media characteristics, eliminating the need for manual adjustment while maintaining optimized sound quality.
Solution Approach 2:
The system prepares optimized sound profiles in advance by pre-configuring equalizer settings for different media types on the tuning server. When a media type is detected, the corresponding pre-prepared profile is quickly retrieved and applied, eliminating the need for real-time manual adjustment and ensuring optimal sound quality is immediately available for each genre.
3Reliability
If generic amplifier settings are used for all media, then device complexity is reduced, but adaptability to vehicle noise environments and sound quality deteriorate
Solution Approach 1:
The patent applies local quality by tailoring the equalizer settings specifically to match both the media type and the vehicle noise environment. Instead of using uniform settings for all situations, the system retrieves specific sound profiles from the tuning server that are optimized for particular combinations of media types and acoustic conditions, allowing different parts of the frequency spectrum to be adjusted according to their specific requirements.
Solution Approach 2:
The system changes amplifier parameters dynamically based on detected media identifying information. By analyzing the media type and retrieving corresponding sound profiles, the equalizer adjusts frequency response parameters, gain settings, and other amplifier characteristics to optimize sound quality for each specific media and environmental condition combination.
