Speaker Box Air-Permeable Spacer Protruding Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing speaker boxes with air-permeable spacers require significant space for sealing and have poor structural strength due to the need for a large circle of glue for sealing the side wall.
Innovation Solution
A speaker box design featuring a housing with protruding portions on the inner surface of the side wall to support and fix the air-permeable spacer, reducing the need for extensive glue sealing and enhancing structural strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the side wall of the air-permeable spacer is fixed to the housing with a circle of glue, then the air-permeable spacer is secured in place, but it requires comparatively larger space and has poor structural strength
Solution Approach 1:
The side wall of the air-permeable spacer is divided into multiple segments with through-holes, allowing it to be fixed at discrete points rather than requiring continuous glue sealing. This segmentation reduces the space needed for sealing while maintaining structural strength through distributed attachment points.
Solution Approach 2:
Instead of uniform glue sealing along the entire side wall, the fixation is concentrated at specific local positions where through-holes are provided. This local quality approach applies sealing only where necessary, reducing overall space consumption while achieving adequate fixation strength.
2Reliability
If a large circle of glue is used to seal the side wall, then the air-permeable spacer is securely fixed, but it consumes more internal space
Solution Approach 1:
The continuous glue sealing circle is segmented into discrete fixation points at the through-holes. This segmentation maintains fixation reliability through multiple anchored points while significantly reducing the total amount of sealing material and space required compared to a continuous circle of glue.
Solution Approach 2:
The excessive glue material from the continuous sealing circle is extracted and replaced with minimal sealing at discrete through-hole locations. This extraction eliminates unnecessary space consumption while preserving the essential fixation function at critical points.
3Ease of manufacture
If the air-permeable spacer uses a traditional side wall fixation method, then it can be assembled, but the structural strength is poor
Solution Approach 1:
The side wall is segmented with through-holes that enable discrete fixation points. This segmentation maintains assembly ease by providing clear localization points for sealing while dramatically improving structural strength through distributed reinforcement at the through-hole locations.
Solution Approach 2:
The air-permeable spacer combines the base material with reinforcement ribs that extend through the thickness, creating a composite structure. This composite design maintains manufacturing simplicity while significantly enhancing structural strength at the fixation points.

AI summary
The present invention provides a speaker box including a housing and a speaker unit accommodated in the housing. The speaker box also includes an air-permeable spacer accommodated in the housing. The housing includes a bottom wall away from the speaker unit and a side wall bent and extended from the bottom wall toward the speaker unit. The air-permeable spacer is enclosed with the bottom wall and the side wall to form a containment space filled with sound absorbing powder. The inner surface of the side wall is provided with a number of protruding portions that support the air-permeable spacer. The air-permeable spacer is fixedly connected with the protruding portion. The speaker box of the present invention saves internal space and increases the filling amount of the sound absorbing powder.
