Speaker Box Breathable Separator for Height Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing speaker boxes in portable electronic devices are hindered by the need for a metal breathable separator, which increases the device's height, contradicting the trend of miniaturization.
Innovation Solution
A speaker box design with a housing body and sounding unit that incorporates a breathable separator enclosed within the upper and lower housings, forming a sound absorbing cavity, and a sealed part that seals the through hole without extending beyond the bottom wall, allowing for a reduced height and cost-effective miniaturization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a metal breathable separator is used to cover the sounding unit, then acoustic performance is improved, but the height of the speaker box increases
Solution Approach 1:
The breathable separator is nested within the rear cavity of the speaker box, enclosed by the upper and lower housings. The separator is positioned such that it does not extend beyond the bottom wall, effectively nesting it within the existing housing structure rather than adding external height.
Solution Approach 2:
The breathable separator is designed with a three-dimensional structure that includes a fixed part, a breathable part with air circulation holes, and a sealed part. This dimensional arrangement allows the separator to be positioned at an angle relative to the bottom wall, optimizing space utilization without increasing the overall height.
2Reliability
If the breathable separator is enclosed with upper and lower housings to form a sound absorbing cavity, then acoustic performance is enhanced, but device complexity increases
Solution Approach 1:
The breathable separator serves multiple functions simultaneously: it acts as a acoustic barrier, a sound absorbing element, and a structural component enclosing the rear cavity. The sealed part of the separator also serves as both a sealing element and a structural support.
Solution Approach 2:
The upper housing, lower housing, and breathable separator are merged into a unified structure that forms the sound absorbing cavity. The bracket connects these components, integrating them into a single functional assembly rather than separate elements.
3Reliability
If the sealed part of the breathable separator extends beyond the bottom wall, then sealing effectiveness is improved, but the height of the speaker box increases
Solution Approach 1:
The sealed part of the breathable separator is designed with localized sealing properties at critical locations (the through hole in the bottom wall and the interface with the magnetic bowl) rather than extending uniformly beyond the bottom wall. This provides effective sealing without increasing overall height.
Solution Approach 2:
The sealed part extends partially beyond the bottom wall to provide adequate sealing at the through hole and magnetic bowl interface, but not excessively beyond the bottom wall. This partial extension is sufficient for sealing effectiveness while avoiding unnecessary height increase.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
