Multi-Zone Audio Playback Control for In-Car Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In-car audio systems face interference issues when multiple audio sources are played simultaneously in response to voice instructions from different seats, making it difficult for drivers to clearly hear navigation audio due to overlapping music or other audio sources.
Innovation Solution
A method and apparatus that determine the location of each loudspeaker and corresponding voice signal, allowing for separate audio playback in distinct areas within a vehicle, using sound source localization, area determination, voice recognition, and playback control modules to ensure non-interfering audio playback for different zones.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple loudspeakers play multiple audio sources simultaneously in response to voice instructions from different seats, then the system responds to multiple users, but the audio sources interfere with each other making it difficult for drivers to clearly hear navigation audio
Solution Approach 1:
The patent divides the vehicle interior into multiple independent audio zones based on speaker location information. Each zone can play different audio sources simultaneously without interfering with other zones. The playback control module segments the audio output by controlling different loudspeakers to play different audio streams according to the determined voice instruction areas.
2Ease of operation
If the system plays audio for multiple areas simultaneously, then different passengers can hear their intended audio, but the device complexity increases due to location determination and zone management
Solution Approach 1:
The system automatically determines speaker location information and corresponds it to voice signals without requiring manual configuration. The playback control module autonomously manages zone assignment and audio distribution based on the determined location data, eliminating the need for complex manual setup while maintaining separate audio playback for different passengers.
