Portable Computer Speaker Housing With Bottom Swelling Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable computers face a challenge in improving sound quality through speaker housing size increases, which either thickens the device or occupies more space, compromising usability and component placement.
Innovation Solution
A portable computer design featuring a casing with a swelling portion on the bottom wall to house a larger speaker housing, utilizing cushioning materials and a rubber foot for vibration absorption and anti-slip functionality, allowing increased speaker capacity without enlarging the overall casing size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the speaker housing is increased in size in the height direction to improve sound quality, then the sound quality is improved, but the thickness of the portable computer increases
Solution Approach 1:
The patent changes the spatial arrangement by creating a swelling portion in the bottom wall that extends downward, allowing the speaker housing to be enlarged in the vertical direction without increasing the overall thickness of the portable computer. This dimensional reconfiguration resolves the contradiction between sound quality and portability.
Solution Approach 2:
The speaker housing is nested within the swelling portion of the bottom wall, creating a nested structure where the speaker housing is contained within the recessed area. This nesting approach allows the speaker housing to be enlarged while maintaining the external dimensions of the portable computer.
2Reliability
If the speaker housing is increased in size in the width direction to improve sound quality, then the sound quality is improved, but the area occupied by the speaker housing increases, requiring reduction of other components
Solution Approach 1:
Instead of expanding the speaker housing in the width direction, the patent utilizes the vertical dimension by creating a swelling portion that extends downward from the bottom wall. This allows the speaker housing to be enlarged without increasing the horizontal footprint, thus avoiding interference with other components like the PCB.
3Reliability
If the capacity of the speaker housing is changed to improve sound quality, then the sound quality is improved, but part of the speaker housing projects over the keyboard plane, reducing usability
Solution Approach 1:
The patent directs the expansion of the speaker housing downward into the swelling portion rather than upward toward the keyboard. This dimensional redirection ensures that the increased speaker housing capacity does not project over the keyboard plane, maintaining usability while improving sound quality.
Solution Approach 2:
The swelling portion acts as an intermediary structure that accommodates the enlarged speaker housing. By providing this intermediate recessed space in the bottom wall, the speaker housing can be enlarged without directly interfering with the keyboard or other upper components.
