Wearable Sound Sealing via Coupling Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Small-sized wearable devices, such as earsets and earbuds, face challenges in implementing a sealing structure for sound elements due to limited space, leading to sound quality deterioration.
Innovation Solution
A wearable device with a sound sealing structure that includes a housing with sound holes, substrates, and sound element portions connected via a duct structure, featuring coupling structures to prevent movement and ensure sealing between the sound holes and ducts, thus maintaining sound quality without increasing the device's overall size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a sealing structure is added to the sound path of the sound element, then sound quality is improved, but the device size increases
Solution Approach 1:
The housing structure is merged with the sealing function by forming a coupling structure that integrates the sound element portion mounting with the sound hole sealing. The housing simultaneously serves as both the structural enclosure and the sealing element, eliminating the need for separate sealing components.
Solution Approach 2:
The coupling structure formed between the housing and sound element portion serves multiple functions: it mechanically secures the sound element in place while simultaneously creating the sound sealing. This multi-functional design prevents sound leakage without requiring additional space for dedicated sealing components.
2Reliability
If a sealing structure is added to the sound path of the sound element, then sound leakage is prevented, but the device complexity increases
Solution Approach 1:
The housing structure is merged with the sealing function by forming a coupling structure that integrates the sound element portion mounting with the sound hole sealing. The housing simultaneously serves as both the structural enclosure and the sealing element, eliminating the need for separate sealing components.
Solution Approach 2:
The housing automatically provides the sealing function through its own structural features (the coupling structure) rather than requiring external sealing components. The coupling structure between the housing and sound element portion inherently creates the sound seal as part of its mechanical connection function.

AI summary
The present disclosure discloses a wearable device with a sound sealing structure. The disclosed device may include a housing having at least one or more sound holes, at least one or more substrates fixed inside the housing, and at least one or more sound element portions disposed in the housing to face a 1st direction(+) and including a sound path comprising a duct structure for connection to the sound hole. At least one or more coupling structures on which a coupling force is exerted in a 2nd direction facing a vertical direction of the 1st direction may be formed between the housing and the sound element portion, and the sound element portion may be prevented from and/or resist being moved back in a 1st direction(−) due to the at least one or more coupling structures.
