Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current automotive audio systems require multiple signal processors to account for different vehicle types and destinations, leading to increased manufacturing complexity and costs.
Innovation Solution
An audio system with a signal processor and database that associates audio signals with geographic regions, allowing selection of the appropriate region to generate a corresponding audio output, enabling a single processor to be used across various vehicles and destinations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple signal processors are used to account for different vehicle types and destinations, then the audio output quality is improved, but the manufacturing complexity and costs increase
Solution Approach 1:
The patent implements a single signal processor that can perform multiple functions by loading different audio signals from a database based on vehicle type and destination. Instead of having separate dedicated signal processors for each vehicle configuration, one universal processor handles all configurations by selecting and loading the appropriate audio signal, thereby reducing manufacturing complexity while maintaining audio quality.
Solution Approach 2:
The patent changes the audio signal parameters dynamically by loading different pre-configured audio signals into the signal processor based on the vehicle type and destination. The signal processor can switch between different audio configurations (such as different equalization settings, gain values, or frequency responses) by loading appropriate data from the database, allowing one processor to adapt to multiple vehicle configurations without physical changes.

Solution Approach 2:
The patent uses a database to store multiple audio signal configurations that can be loaded into the signal processor as needed. Rather than manufacturing multiple physical processors with hardwired configurations, the system creates software copies of different audio configurations that can be loaded and unloaded from the database, significantly reducing manufacturing costs while maintaining the ability to provide customized audio outputs for different vehicle types and destinations.

AI summary
An audio system for use in an automotive vehicle is provided. The audio system is configured to detect the removal of the removable speaker and adjust the audio signal to the fixed speakers so as to maintain the quality of sound within the vehicle. The audio system includes a signal processor configured to detect the presence of the removable speaker. The audio system distributes the frequency transmitted to the removable speaker to the speakers within the automotive vehicle so as to maintain the same sound quality when the removable speaker is removed.
