Audio Interface Structure With Selective Sealing for Waterproof Sound
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Audio devices with waterproofing structures often experience degradation in sound quality and volume due to the presence of waterproofing components, which can impede the efficient design and functionality of these devices.
Innovation Solution
The design omits waterproofing at the sound output portion and alters the structure of connection terminals and sensors, using a housing with a substrate and interface structure that includes a connection terminal exposed to the environment, a sensor covered by a window member, and a waterproofing member to seal the interface structure, allowing sound to be transmitted directly to the user without passing through waterproofing components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If waterproofing structures are implemented in audio devices, then water resistance is improved, but sound quality and volume are degraded
Solution Approach 1:
The device is divided into separate functional zones: a first opening for sound output without waterproofing to maintain audio quality, and a second opening for charging/port functions with waterproofing protection. This segmentation allows each zone to be optimized for its specific function without compromising the other.
Solution Approach 2:
Different parts of the device have different waterproofing characteristics: the sound output area remains open and unsealed to preserve acoustic properties, while the charging port and sensor areas are selectively sealed. This local differentiation of quality ensures water resistance where needed without degrading sound output.
2Adaptability or versatility
If connection terminals and sensors are exposed to external environment, then functionality is improved, but water resistance is degraded
Solution Approach 1:
The interface structure is segmented into multiple functional areas: connection terminals are exposed through a first opening for charging and data transfer functionality, while sensors are covered by a window member through a second opening. This segmentation allows selective exposure of components based on their functional requirements and water resistance needs.
Solution Approach 2:
A window member is introduced as an intermediary component that covers the sensor while allowing light transmission for sensor functionality. This mediator enables the sensor to maintain both its external exposure for functionality and protection for water resistance simultaneously.
3Reliability
If waterproofing structures are added to protect exposed components, then water resistance is improved, but device complexity increases
Solution Approach 1:
The waterproofing member is merged with the interface structure as an integrated component rather than a separate addition. This combining approach provides water resistance for exposed components while avoiding the complexity of multiple separate waterproofing layers or structures.
Solution Approach 2:
A thin waterproofing member is used to provide water resistance without adding significant structural complexity. This thin film approach protects exposed components effectively while maintaining a simple and compact device structure.

AI summary
An electronic device is disclosed, including a housing, and an interface structure disposed at least partly in the housing. Th interface structure includes: a substrate, a connection terminal disposed on the substrate, a part of which is exposed to an external environment through a first opening of the housing, a sealing part disposed where the substrate and the connection terminal are connected, blocking exposure of the connected portion to the external environment, a sensor disposed on the substrate adjacent to the connection terminal, a window member disposed on the substrate to cover the sensor while exposing at least a portion of the sensor to the external environment through a second opening of the housing, and a waterproofing member disposed between the window member and the substrate to form a seal between a portion of the window member and the substrate.
