Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional externally coupled subwoofer speakers experience package working vibration and noise, which affects the service life of plastic parts and increases costs and production complexity, necessitating a solution that reduces vibration and noise while minimizing space and cost.
Innovation Solution
A dual core speaker assembly with a speaker adapter featuring a main body with symmetric mounting portions, a bottom base for support, and an inner cavity that can be evacuated, filled with foam, or filled with air, allowing for reduced vibration and noise, extended plastic part service life, and improved acoustic performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If foam is filled into the adapter to reduce vibration, then vibration and noise are reduced, but cost and production process complexity increase
Solution Approach 1:
The patent extracts the vibration reduction function from the foam filling approach and relocates it to the adapter structure design itself. The adapter incorporates a cavity structure that inherently absorbs vibration without requiring additional foam materials, thereby eliminating the complex production process of foam filling while maintaining vibration reduction effectiveness.
Solution Approach 2:
The adapter cavity acts as an intermediary vibration absorption mechanism between the speaker and the mounting surface. This cavity structure serves as a built-in damping element that mediates vibration without requiring external foam materials, simplifying the overall system while maintaining vibration reduction performance.
2Object-affected harmful factors
If foam is filled into the adapter to reduce vibration, then vibration and noise are reduced, but cost increases
Solution Approach 1:
The patent eliminates the need for foam materials by integrating vibration reduction functionality directly into the adapter structure. The cavity design provides vibration absorption without requiring additional costly foam fillings, thereby reducing material costs and simplifying the manufacturing process.
Solution Approach 2:
The adapter structure itself provides the vibration reduction function through its cavity design, making the system self-sufficient without requiring external foam materials. This self-service approach eliminates the need for additional vibration damping materials and simplifies the manufacturing process.
3Reliability
If a dual core speaker assembly is used, then vibration and noise are reduced and service life is extended, but device complexity increases
Solution Approach 1:
The patent merges two speakers into a single integrated assembly mounted on a common adapter structure. This combination allows the speakers to work together to reduce vibration and noise while extending service life, and the unified adapter design simplifies the overall installation process despite the increased complexity of having two speakers.
