Mesh Structure Planar Edge for Acoustic Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable electronic devices face challenges in providing high-quality audio sound output and pickup while being made smaller and thinner, due to difficulties in sealing mesh barriers effectively against the outer housing, which allows foreign substances to enter and hinders acoustic sealing.
Innovation Solution
The development of a mesh structure with a modified outer peripheral region that facilitates improved acoustic sealing by forming a planar surface, allowing for reliable sealing with the audio chamber and housing, while also serving as a cosmetic barrier to obscure vision and block foreign substances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a mesh barrier is used to block foreign substances from entering the audio port, then protection against foreign substances is improved, but acoustic sealing becomes difficult and unreliable
Solution Approach 1:
The mesh structure is designed with different properties in different regions: the inner region maintains an interwoven configuration for foreign substance blocking, while the outer peripheral region is configured with a planar surface specifically for acoustic sealing. This local differentiation allows each region to optimize its function without compromising the other.
Solution Approach 2:
The mesh structure is segmented into functionally distinct regions: an inner region for particle blocking and an outer peripheral region for acoustic sealing. This segmentation allows the structure to simultaneously perform both blocking and sealing functions by assigning specific geometric characteristics to each segment.
2Volume of moving object
If the device is made smaller and thinner to improve portability, then compactness is improved, but acoustic sealing of mesh barriers becomes more difficult
Solution Approach 1:
The outer peripheral portion of the mesh structure is specifically configured with a planar surface to provide reliable acoustic sealing in compact spaces. This localized geometric modification enables effective sealing without requiring additional thickness or complex sealing mechanisms, thus maintaining device compactness while improving sealing reliability.
3Object-affected harmful factors
If a mesh barrier with interwoven structure is used to block foreign substances, then protection is improved, but sealing surface reliability deteriorates
Solution Approach 1:
The mesh structure employs different geometric configurations in different regions: the inner region maintains the interwoven pattern necessary for blocking foreign substances, while the outer peripheral region is specifically formed with a planar surface to provide a reliable sealing interface. This local differentiation resolves the conflict between blocking effectiveness and sealing precision.
Solution Approach 2:
The mesh structure is divided into functional segments where the inner segment provides particle blocking through its interwoven configuration, and the outer segment provides acoustic sealing through its planar surface configuration. This segmentation allows each segment to be optimized for its specific function.

AI summary
A portable electronic device that provides compact configurations for audio elements are disclosed. The audio elements can be drivers (e.g., speakers) or receivers (e.g., microphones). According to one aspect, mesh structures, such as mesh barriers, are formed to facilitate improved acoustic sealing in a space efficient manner. In one embodiment, a mesh barrier for an audio port can be reliably acoustically sealed (or coupled) with an audio chamber and/or outer device housing in a space efficient manner. A mesh barrier can serve to block undesired foreign substances from entry or further entry into an audio port and/or serve as a cosmetic barrier which obscures vision into an audio port. In one embodiment, a portion of a mesh structure can be provided with a substantially planar surface that facilitates improved acoustic sealing.
