Sounding Device Front-Cover Spacer for Waterproof Acoustic Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sounding devices face challenges with complex assembly, reduced acoustic performance due to the attachment of a waterproof and breathable spacer on the diaphragm, and occupied internal space affecting sound quality.
Innovation Solution
A sounding device design featuring a front cover with a waterproof sealing ring and a waterproof and breathable spacer fixed on the front cover body, rather than the diaphragm, ensuring easy assembly, improved waterproof performance, and maintaining acoustic quality by avoiding spacer attachment to the diaphragm.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the waterproof and breathable spacer is attached to the diaphragm, then waterproof performance is improved, but the structure becomes complicated and assembly becomes difficult
Solution Approach 1:
The patent extracts the waterproof and breathable spacer from the diaphragm and relocates it to the front cover. This separation removes the spacer from the vibration system, simplifying the diaphragm structure while maintaining waterproof protection at the front cover assembly point.
Solution Approach 2:
The patent segments the waterproofing function from the vibration function by placing the waterproof and breathable spacer on the front cover rather than the diaphragm. This allows independent optimization of both the vibration system and waterproofing system.
2Reliability
If the waterproof and breathable spacer is attached to the diaphragm, then waterproof performance is improved, but acoustic performance is reduced
Solution Approach 1:
The patent extracts the waterproof and breathable spacer from the diaphragm to preserve the diaphragm's acoustic performance. By relocating the spacer to the front cover, the diaphragm remains free of attachments that would interfere with its vibration characteristics and sound quality.
3Reliability
If the waterproof and breathable spacer is attached to the diaphragm, then waterproof performance is improved, but internal space is occupied affecting acoustic effect
Solution Approach 1:
The patent extracts the waterproof and breathable spacer from the internal cavity space by relocating it to the front cover. This frees up the internal space for acoustic optimization while maintaining the waterproofing function at the front cover assembly.
4Reliability
If the waterproof and breathable spacer is attached to the diaphragm, then waterproof performance is improved, but assembly becomes difficult
Solution Approach 1:
The patent implements preliminary action by pre-assembling the waterproof and breathable spacer with the front cover before final assembly. This allows the spacer to be integrated into the front cover structure in advance, simplifying the overall assembly process and improving assembly ease.
