Electronic Device Waterproofing Structure for Protected Audio Openings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices face challenges in maintaining waterproofing performance at penetrating holes due to the vulnerability of waterproof members to breakage from sharp foreign substances, complicating assembly and reducing sound transmission efficiency.
Innovation Solution
A waterproof structure is implemented with a waterproof film and protection member, where the waterproof film is positioned between a recessed portion and an audio module, and a protection member is placed in the recessed space to protect the waterproof film from foreign substances, while allowing sound transmission through misaligned openings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a waterproof member is disposed in the duct structure to ensure waterproofing performance, then waterproofing performance is improved, but the waterproof member may be broken by sharp foreign substances such as pins
Solution Approach 1:
A protection member is introduced as an intermediary element between the waterproof member and the penetrating hole. The protection member has a protective portion that extends toward the penetrating hole to shield the waterproof member from sharp foreign substances, while maintaining the waterproofing function through the sound transmission portion.
Solution Approach 2:
The waterproofing structure is divided into distinct functional components: a waterproof member for blocking moisture, a protection member for mechanical protection, and a sound transmission portion for acoustic functionality. This segmentation allows each component to optimize its specific function without compromising others.
2Reliability
If a separate waterproof member protection device is added to prevent breakage of the waterproof member, then waterproof member protection is improved, but the housing becomes difficult to assemble due to complicated interior structure
Solution Approach 1:
The protection member is merged with the waterproof member as a single integrated component. The protective portion and sound transmission portion are formed as one piece that is directly attached to the waterproof member, eliminating the need for separate protection devices and simplifying the housing interior structure.
Solution Approach 2:
The protection member serves multiple functions simultaneously: it provides mechanical protection to the waterproof member, maintains the waterproof seal, and enables sound transmission. This multi-functionality reduces the total number of components needed in the housing structure.
3Reliability
If more members for waterproofing are required to ensure waterproofing performance, then waterproofing performance is improved, but waterproofing points increase making it difficult to completely achieve waterproofing performance
Solution Approach 1:
Multiple waterproofing functions are merged into a single waterproof member component. The waterproof member, protection member, and sound transmission portion are integrated into one assembly that provides comprehensive waterproofing at the penetrating hole without requiring multiple separate waterproofing points.

AI summary
An electronic device includes a display forming at least a portion of the front surface of the electronic device; a frame structure on which the display is disposed and which forms at least a portion of the side surface of the electronic device, the frame structure including a first opening portion exposed to the outside of the electronic device and oriented in a first direction and a recessed portion formed adjacent to the first opening portion; the audio module disposed adjacent to the recessed portion; a waterproof film disposed between the recessed portion and the audio module; a first adhesive member for attaching the waterproof film and the frame structure; a second adhesive member for attaching the audio module and the waterproof film; and a protection member disposed, facing the first opening portion, within a recessed space formed by the recessed portion.
