Microphone Structure Stabilizing FPCB Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing microphone module sealing structure in electronic devices is inadequate as the conductive connection member only supports part of the flexible printed circuit board (FPCB), leading to sagging and compromised sealing between the microphone module and the camera housing.
Innovation Solution
A structure that includes a first and second printed circuit board (PCB) with a microphone module on the second PCB, multiple connection members for electrical connection between the PCBs, a cover member with a sound hole, and a sound channel to connect the sound holes, ensuring stable support of the FPCB and improved sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conductive connection member is used to electrically connect the FPCB and main PCB, then electrical connection is achieved, but the FPCB sags due to gravity because the connection member supports only part of the FPCB
Solution Approach 1:
The connection member is divided into a first connection member extending from the main PCB and a second connection member extending from the FPCB. This segmentation allows the connection member to support the FPCB at multiple points, preventing sagging while maintaining electrical connection reliability.
Solution Approach 2:
A support member is introduced as an intermediary component between the FPCB and the connection member. The support member provides additional support to the FPCB, preventing it from sagging due to gravity while allowing the connection member to maintain its electrical connection function.
2Device complexity
If the connection member supports only part of the FPCB, then the structure is simple, but the sealing between the microphone module and camera housing is compromised
Solution Approach 1:
The connection member is segmented into multiple parts (first connection member, second connection member, and support member) that work together to provide comprehensive support to the FPCB. This segmentation enables better sealing without excessive complexity.
Solution Approach 2:
The connection member structure is extended into the vertical dimension by adding a support member that extends in the thickness direction of the FPCB. This dimensional addition provides better support for sealing while maintaining reasonable structural complexity.
