Speaker Assembly with Integrated Damping and Leakage Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing speaker designs with mesh and foam configurations for air leakage adjustment and protection compromise acoustic performance due to reduced back cavity and excessive material usage, particularly in small size designs.
Innovation Solution
A speaker assembly with a damping element and leakage controllers on a common layer, reducing height and increasing back cavity, while using a single adhesive layer to minimize material waste and enhance acoustic performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mesh and foam are attached using two layers of double-side adhesive, then the mesh and foam are securely fixed for air leakage adjustment and protection, but the back cavity is reduced and acoustic performance deteriorates
Solution Approach 1:
The patent combines the mesh and foam into a single integrated layer structure, eliminating the need for two separate adhesive layers. This merging approach maintains the protective and air leakage adjustment functions while reducing the total thickness of the assembly, thereby preserving back cavity volume.
Solution Approach 2:
The patent extracts one of the double-side adhesive layers from the assembly, retaining only a single adhesive layer. This extraction eliminates unnecessary material while maintaining the structural integrity and securing function of the mesh and foam components.
2Reliability
If two layers of double-side adhesive are used to fix mesh and foam, then secure attachment is achieved, but material waste increases and manufacturing cost rises
Solution Approach 1:
The patent removes one of the two double-side adhesive layers from the assembly, extracting unnecessary material while retaining sufficient attachment security through the optimized single-layer configuration.
Solution Approach 2:
By merging the attachment function into a single adhesive layer rather than using two separate layers, the patent reduces adhesive material consumption while maintaining effective bonding between components.
3Object-affected harmful factors
If mesh and foam are stacked in multiple layers, then air leakage adjustment and protection functions are achieved, but the structure becomes complex and small size design is hindered
Solution Approach 1:
The patent merges the mesh and foam into a single integrated layer, combining multiple protective functions into one structure. This eliminates the complexity of stacking multiple separate layers while maintaining air leakage control and protection capabilities.
Solution Approach 2:
The integrated mesh-foam layer performs multiple functions simultaneously: protection, air leakage adjustment, and structural support. This multi-functionality eliminates the need for separate stacked layers, simplifying the overall structure.

AI summary
The present application discloses a speaker assembly. The speaker assembly includes a sound generator having a sound radiation surface and a back surface opposite to the sound radiation surface; at least one leakage area formed on the back surface; at least one leakage controller corresponding to the leakage area and covering the leakage area; a damping element disposed on a plane on which the leakage controller is disposed. The damping element is arranged between adjacent two leakage areas. By the configuration, the height of the speaker assembly is reduced.
