Integrated Loudspeaker Frame Assembly Without Glue Bonding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing loudspeakers require large amounts of glue for bonding components, leading to environmental concerns and complex manufacturing processes, while also needing to reduce part count, improve manufacturing efficiency, and achieve lower costs and better acoustic performance.
Innovation Solution
A loudspeaker design with an integrated frame that surrounds and fixes the yoke, eliminating the need for glue between the top plate, magnet, and yoke, using aligned holes and a separate sleeve for precise alignment, and integrating the frame, strut, and flange through injection molding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If glue bonding is used to bond the top plate, magnet and yoke together, then the components are securely fixed, but a large volume of glue is used which is not environmentally friendly and increases manufacturing complexity
Solution Approach 1:
The patent merges the frame, strut, and flange into a single integrated component formed by injection molding. This integration eliminates the need for separate glue bonding operations between these parts, reducing manufacturing complexity while maintaining structural integrity through the unified design
2Adaptability or versatility
If multiple separate parts are used for the frame, strut and flange, then manufacturing flexibility is maintained, but the number of parts increases and manufacturing efficiency decreases
Solution Approach 1:
The frame, strut, and flange are combined into a single integrated part through injection molding, reducing the total number of components and assembly steps. This improves manufacturing efficiency and productivity while the integrated design maintains the necessary structural and functional flexibility
3Reliability
If glue bonding is used to bond the yoke to the frame, then the components are securely fixed, but manufacturing time increases and production efficiency decreases
Solution Approach 1:
By integrating the frame, strut, and flange into a single molded part, the patent eliminates the time-consuming glue bonding process. The integrated structure is formed in a single manufacturing operation, significantly reducing production time while maintaining secure component fixation through the unified design
4Reliability
If traditional bonding methods are used, then components are securely assembled, but material cost and market price increase
Solution Approach 1:
The integration of frame, strut, and flange into a single injection-molded part eliminates the need for glue materials and reduces the total material required for assembly. This reduces both material costs and manufacturing costs, leading to a more cost-effective solution while maintaining assembly reliability
