Integrated Frame and Support Structure for Micro Sound Generator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manufacturing process of miniaturized micro sound generating devices is complex due to the need for separate support structures to reduce voice coil swing amplitude, which complicates assembly and affects sound quality.
Innovation Solution
An integrated frame and support structure is formed through injection molding, where the support is formed directly with the frame, and the voice coil is bonded to the support, simplifying the assembly process and improving sound quality by reducing swing amplitude.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate support structure is added to reduce voice coil swing amplitude, then sound quality is improved, but device complexity and manufacturing complexity increase
Solution Approach 1:
The support structure is merged with the frame to form an integrated component. The frame includes a receiving space with a support portion that directly supports the voice coil, eliminating the need for separate support structures while maintaining the function of reducing swing amplitude and improving sound quality
2Reliability
If a separate support structure is added to reduce voice coil swing amplitude, then sound quality is improved, but manufacturing process complexity increases
Solution Approach 1:
The frame and support structure are formed as an integrated component through injection molding. The frame includes a receiving space with an integrated support portion, eliminating separate manufacturing steps for assembling support structures and simplifying the overall manufacturing process
3Reliability
If a separate support structure is added to reduce voice coil swing amplitude, then voice quality is improved, but assembly process complexity increases
Solution Approach 1:
The support function is integrated into the frame structure, which is formed as a single piece through injection molding. The frame includes a receiving space with a built-in support portion that directly holds the voice coil, eliminating multiple assembly steps for connecting separate support structures to the frame and voice coil
