Inclined Microphone Placement in Slim Display Bezel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display apparatuses with slim bezel designs face challenges in incorporating microphones effectively, as traditional placements at the top, side, or rear result in reduced sound quality due to diffraction, necessitating a solution that maintains aesthetics while enhancing sound reception.
Innovation Solution
Incorporating microphones between the bezel and display module in a forward and inclined position, with a microphone case formed from elastic material, to minimize bezel width and maximize sound reception without compromising design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the microphone is disposed at the top, side, or rear of the display apparatus, then the slim bezel design is maintained, but the sound quality is reduced due to diffraction
Solution Approach 1:
The microphone is positioned in the forward direction between the bezel and display module rather than at top/side/rear positions, changing the spatial dimension of microphone placement. This forward positioning allows the microphone to receive sound directly from the user without diffraction while maintaining the slim bezel aesthetic design.
Solution Approach 2:
The microphone is nested between the bezel and the display module, utilizing the space between these two components. This nesting approach allows the microphone to be positioned optimally for sound reception without increasing the external dimensions or compromising the slim bezel design.
2Reliability
If the microphone is disposed in front of the display apparatus, then sound quality is improved, but the bezel width is increased
Solution Approach 1:
The microphone is nested between the bezel and the display module, utilizing the internal space between these components. This allows the microphone to be positioned in the forward direction for optimal sound reception without increasing the external bezel width, as the microphone occupies space that would otherwise be empty.
Solution Approach 2:
Instead of positioning the microphone in the lateral dimensions (which would increase bezel width), the microphone is positioned in the forward direction between the bezel and display module. This dimensional change allows optimal sound reception while maintaining the original bezel width.
3Reliability
If the microphone is positioned to be inclined toward the center of the display portion, then voice recognition is improved, but the structural complexity is increased
Solution Approach 1:
The microphone is inclined at a specific angle toward the center of the display portion, creating a localized optimal positioning for voice recognition. This inclined positioning directs the microphone's sound reception axis toward the user's mouth, improving voice recognition while the complexity is managed by the simple inclination rather than complex mechanical structures.

AI summary
A display apparatus includes a display module, a microphone, a front cover disposed in front of the display module, and a frame is disposed on an inner side of the front cover, and covers an edge of the display module, wherein the front cover includes a display part corresponding to the display portion of the display module, and a bezel which covers an edge of a front side of the display module, and the microphone is disposed to be inclined in a forward direction of a center of the display portion of the display module, and thus, the sound recognition rate of the display apparatus user of the user speaking is increased.
