Sounding Device Shell Segmentation for Diaphragm Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The integration of a diaphragm and shell in sounding devices leads to interference with a side magnetic conductive plate, preventing simultaneous molding and resulting in poor reliability between the side magnetic conductive plate and shell.
Innovation Solution
The shell is divided into two parts, allowing the diaphragm to be integrally formed with one shell and the side magnetic conductive plate with the other, avoiding interference and ensuring a reliable connection by splicing the shells together.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the diaphragm and the shell are integrally molded, then the waterproof function is improved, but the diaphragm and the side magnetic conductive plate interfere with each other during molding
Solution Approach 1:
The shell is divided into a first shell and a second shell. The diaphragm is integrally molded with the first shell, while the side magnetic conductive plate is integrally molded with the second shell. This segmentation allows each component to be molded separately without interference, while still achieving the waterproof function through the integral structure of each segment.
2Reliability
If the side magnetic conductive plate and the shell are integrally molded, then the connection reliability is improved, but the diaphragm and side magnetic conductive plate cannot be simultaneously molded due to die structure limitations
Solution Approach 1:
The shell is segmented into two separate parts: the first shell for integral molding with the diaphragm, and the second shell for integral molding with the side magnetic conductive plate. This segmentation simplifies the die structure requirements by creating two separate molding processes, each with its own dedicated die, thereby achieving high connection reliability without requiring a complex integrated die.
3Ease of manufacture
If the side magnetic conductive plate is bonded to the shell, then the assembly is simplified, but the connection reliability deteriorates
Solution Approach 1:
The side magnetic conductive plate is integrally molded with the second shell, merging these two components into a single piece. This eliminates the need for separate bonding processes while achieving superior connection reliability through the integral structure, combining the benefits of simplified assembly with enhanced connection strength.
