Vehicle Sound System Coordination via Relative Position Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle sound systems lack the ability to independently control sound volume and direction for outdoor use, especially when vehicles are not in motion, and do not effectively coordinate sound output between multiple vehicles to enhance user experience during outdoor activities.
Innovation Solution
A method and apparatus that recognize and control sound systems in multiple vehicles based on relative positions and specifications, using wireless communication to adjust volume, direction, and equalizer settings, with one vehicle acting as a master and others as slaves, to optimize sound output at a recommended position determined by GPS, enabling stereo sound and surround sound effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If sound systems in multiple vehicles are independently controlled, then user convenience and sound quality are improved, but device complexity and control difficulty increase
Solution Approach 1:
The patent merges multiple vehicle sound systems into a single coordinated network where vehicles communicate with each other. The sound systems are combined to create immersive audio experiences (stereo, surround sound) while being controlled through a unified interface on the user's terminal device, reducing the perceived complexity for users.
Solution Approach 2:
The user's terminal device (smartphone, tablet, or one vehicle's sound system) acts as an intermediary controller that manages and coordinates the sound output of multiple vehicles. This mediator handles the complex control logic, position calculations, and sound parameter adjustments, shielding users from the underlying system complexity.
2Reliability
If sound systems are coordinated based on relative positions and specifications, then sound quality and user experience are improved, but measurement precision and control accuracy requirements increase
Solution Approach 1:
The system continuously receives position information from GPS and other sensors of multiple vehicles, and uses this feedback to dynamically adjust sound parameters. The control system monitors relative positions and specifications in real-time, automatically recalculating optimal sound distribution and parameters to maintain high sound quality despite position changes.
Solution Approach 2:
The patent dynamically changes sound system parameters (volume, frequency, direction) based on detected vehicle positions and specifications. By automatically adjusting these parameters according to real-time conditions, the system maintains reliable sound quality without requiring manual precision input from users.
3Ease of operation
If multiple vehicles form a master-slave network for sound control, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The patent segments the control function from the execution function. One vehicle or the user terminal is designated as the master controller that makes decisions, while other vehicles act as slaves that execute commands. This segmentation simplifies the user interface (only one controller needed) while distributing the technical complexity across the networked vehicles.
