Mobile Terminal Speaker Hole Relocation to Edge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for forming speaker holes in mobile communication terminals, particularly in window glass, result in high chipping and cracking rates, leading to inferior shape quality and reduced integrity of the glass, while also compromising the rigidity and yield of the glass material.
Innovation Solution
Forming speaker holes on the edge of the terminal main body instead of the window glass, using a sensor to control the opening and closing of the holes based on the terminal's slanted direction, thereby eliminating the need for shaping within the glass and enhancing the glass's rigidity and yield.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If speaker holes are formed directly in the window glass, then speaker functionality is achieved, but chipping and cracking rates increase and glass integrity deteriorates
Solution Approach 1:
The patent introduces an intermediary structure (speaker hole formed in the terminal main body edge rather than directly in the window glass) to resolve the contradiction. By forming the speaker hole in the terminal main body at the edge corresponding to the window glass outer portion, the harmful shaping process is eliminated from the glass, preventing chipping and cracking while still achieving speaker functionality.
2Strength
If speaker holes are formed in the window glass, then speaker functionality is achieved, but the rigidity of the glass is compromised
Solution Approach 1:
The patent extracts the speaker hole formation from the window glass structure and relocates it to the terminal main body. This extraction eliminates the weakening effect on the glass while preserving speaker functionality, as the speaker hole is now formed in the terminal main body edge rather than in the glass itself.
3Productivity
If speaker holes are formed in the window glass, then speaker functionality is achieved, but the yield of the glass is reduced
Solution Approach 1:
The patent uses the terminal main body edge as an intermediary location for forming speaker holes, corresponding to the edge of the window glass outer portion. This approach eliminates the harmful shaping process from the glass manufacturing process, improving glass yield while maintaining precise speaker hole positioning through the correspondence between the terminal main body edge and window glass outer portion edge.

Function Achieved in This Case
This approach reduces the chipping and cracking issues, improves the integrity and yield of the window glass, and allows for the provision of stereo sound by forming multiple speaker holes that are controlled by an acceleration sensor for optimal sound delivery.
Implementation Method 1
a sensor connected to the speaker, and sensing a direction in which the terminal main body is slanted

AI summary
A mobile communication terminal including: a window glass provided on a front side of a terminal main body; a speaker hole formed on an edge of the terminal main body corresponding to an edge of an outer portion of the window glass, exposed to the outside, and formed to correspond to a speaker provided in the terminal main body; and a sensor connected to the speaker, and sensing a direction in which the terminal main body is slanted, wherein the sensor controls the speaker to open or close the speaker hole according to the direction in which the terminal main body is slanted.
