Vehicle Body Panel Speaker Assembly Using Sealed Resonance Cavities
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing speaker assemblies in vehicles are space-constrained due to the reduction in vehicle size, necessitating a reevaluation of their integration within the vehicle body to optimize interior space without additional components.
Innovation Solution
Integrating speaker assemblies directly into vehicle body panels, forming resonation chambers within these panels, and utilizing existing pillars to house speakers, reducing the need for separate trim components and optimizing space by incorporating ports for ventilation and pressure balance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If speaker assemblies are installed to separate trim components attached to the vehicle body, then the acoustic performance can be maintained, but the interior space is reduced and the number of components increases
Solution Approach 1:
The patent merges the speaker assembly directly into the vehicle body panel structure, eliminating the need for separate trim components. The speaker is mounted within a cavity formed by the body panel itself, combining functions that were previously separated into different components.
Solution Approach 2:
The vehicle body panel serves multiple functions: it provides structural support, forms the speaker cavity, and integrates the speaker mounting structure. This multi-functional design eliminates the need for dedicated trim components solely for speaker housing.
2Length of moving object
If the vehicle size is reduced, then the vehicle dimensions are optimized, but the space available for speaker assemblies is constrained
Solution Approach 1:
The patent utilizes the depth dimension of the vehicle body panel to create the speaker cavity, rather than requiring additional lateral or vertical space. By forming the cavity within the existing panel thickness, speaker assembly space is created without increasing overall vehicle dimensions.
Solution Approach 2:
The speaker assembly is nested within the vehicle body panel structure itself. The cavity is formed by utilizing the space between the inner and outer surfaces of the body panel, effectively nesting the speaker housing within the existing structural component.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This integration method reduces the number of components and maximizes interior space by utilizing existing vehicle body structures, enhancing acoustic performance while minimizing the need for additional trim components.
Implementation Method 1
the internal cavity provides a resonation chamber for the speaker
Implementation Method 2
the port is vented externally of the vehicle body panel
