Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle-mounted karaoke systems without microphones provide a uniform sound effect for all passengers, failing to meet the diverse karaoke singing requirements of different users, and require additional hardware installation.
Innovation Solution
An audio processing method that separates and processes audio signals from multiple zones within a vehicle using sound separation technologies and personalized sound effect processing, allowing for individualized sound effects based on user inputs or features, without the need for additional hardware.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If uniform sound effect is provided for all passengers, then system complexity is reduced, but user experience and adaptability deteriorate
Solution Approach 1:
The patent segments the audio processing system into multiple independent channels corresponding to different passenger zones. Each channel processes audio signals separately, allowing personalized sound effects for each user without requiring a completely separate system for each person. This segmentation enables adaptability while controlling overall system complexity through modular architecture.
Solution Approach 2:
The patent applies different sound effect parameters to different audio channels based on local user requirements. Each channel can have customized sound effects tailored to individual passengers' preferences, creating local quality variations throughout the audio system. This allows high adaptability without proportionally increasing overall system complexity.
2Adaptability or versatility
If additional hardware is installed for personalized sound effects, then sound effect quality improves, but device complexity and cost increase
Solution Approach 1:
The patent makes the existing audio processing system multi-functional by enabling it to handle both uniform and personalized sound effects through software configuration. The same hardware infrastructure supports multiple modes of operation, eliminating the need for separate hardware systems. This universality achieves personalized sound effects without additional hardware complexity.
Solution Approach 2:
The patent replaces hardware additions with software-based audio processing techniques. Instead of installing physical hardware components for personalized sound effects, the system uses digital signal processing algorithms and software configuration to achieve the same functionality. This substitution maintains adaptability while avoiding increased hardware complexity and cost.
3Ease of operation
If separate audio processing is performed for each user, then user experience improves, but processing time and computational resources increase
Solution Approach 1:
The patent pre-configures sound effect parameters and processing templates for different user types or zones before actual audio processing occurs. By preparing processing parameters in advance, the system can quickly apply personalized sound effects without performing complex computations in real-time, thus improving user experience while minimizing processing time delays.
