Earphone Socket Waterproof Sealing via Embedded Housing Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing earphone sockets for mobile terminals face challenges in achieving a simple waterproof structure without occupying excessive internal space, which hinders the development of light and thin designs, and require complex machining processes that increase costs.
Innovation Solution
The earphone socket design features a housing with a thicker first peripheral side wall and a thinner second peripheral side wall, where a sealing member is embedded on the outer surface to surround the opening port, preventing water entry without increasing the overall thickness, and a method involving machining an embedding groove and using a glue portion to fix the sealing member, simplifying the manufacturing process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a waterproof structure is added to the earphone socket, then waterproof reliability is improved, but the internal space is occupied and the design becomes complex
Solution Approach 1:
The patent merges the waterproof sealing function with the existing housing structure by forming an integrated sealing member that combines the housing body and sealing components into a single unified structure, eliminating the need for separate waterproof structures and reducing overall complexity
Solution Approach 2:
The housing structure is designed to serve multiple functions simultaneously: it provides structural support, defines the insertion hole geometry, and incorporates the sealing function through the integrated sealing member, thereby achieving waterproof protection without adding dedicated waterproof components
2Reliability
If a waterproof structure is added to the earphone socket, then waterproof reliability is improved, but the internal space is occupied
Solution Approach 1:
The waterproof sealing function is merged into the existing housing structure through the integrated sealing member, eliminating the need for additional separate waterproof components that would occupy internal space
3Manufacturing precision
If a complex machining process is used to manufacture the earphone socket, then manufacturing precision is improved, but the manufacturing cost increases
Solution Approach 1:
The patent combines multiple machining operations into a single integrated machining process that forms the housing body and sealing member simultaneously, reducing the number of separate manufacturing steps while maintaining precision requirements
Solution Approach 2:
The sealing member structure is pre-formed as an integral part of the housing during the initial machining process, eliminating the need for subsequent separate sealing component manufacturing and assembly operations

AI summary
The present disclosure provides a mobile terminal, an earphone socket and a method for manufacturing an earphone socket. The earphone socket includes a housing and a sealing member. The housing has an insertion hole surrounded by a peripheral side wall, the peripheral side wall has a first peripheral side wall located at an inner portion of the insertion hole and a second peripheral side wall located at an outer portion of the insertion hole, the first peripheral side wall has a thickness greater than that of the second peripheral side wall, and the second peripheral side wall has an opening port at an outer end of the insertion hole. The sealing member is embedded on an outer surface of the housing, and surrounds a periphery of the opening port, and at least a part of the sealing member extends to the first peripheral side wall.
