Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional small-size speaker systems face challenges in reproducing bass sound due to acoustic stiffness limitations, as the reproduction limit of bass sound is determined by the cabinet capacity, and existing techniques using activated carbon struggle to maintain effective air gaps and shape integrity, especially in miniaturized systems.
Innovation Solution
A speaker system design featuring a cabinet with protruding sections that support and secure the gas adsorbing material, such as activated carbon, to increase the contact area and equivalent chamber capacity, reducing acoustic loss and maintaining the shape even in irregularly shaped chambers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If activated carbon is used as gas adsorbing material in conventional speaker systems, then the bass sound reproduction is improved, but the shape of activated carbon cannot be maintained due to deformation by vibration
Solution Approach 1:
The patent introduces a supporting material as an intermediary between the activated carbon and the cabinet. This supporting material has a netted structure with pores that allows air to pass through while providing mechanical support to the activated carbon, preventing its deformation under vibration. The supporting material acts as a mediator that maintains the functional relationship between the activated carbon and the acoustic environment while protecting the activated carbon's structural integrity.
2Volume of moving object
If the speaker system is miniaturized, then the cabinet size is reduced, but the contact area between activated carbon and chamber space is insufficient
Solution Approach 1:
The supporting material is designed with a porous netted structure that has pores allowing air to pass through. This porous structure enables the supporting material to provide mechanical support while maintaining acoustic permeability. The porosity allows the material to fulfill dual functions: structural support for the activated carbon and acoustic transparency for the bass sound reproduction, effectively solving the space limitation in miniaturized speaker systems.
3Ease of manufacture
If conventional supporting material is used, then activated carbon is supported, but air gaps cannot be formed effectively due to deformation
Solution Approach 1:
The supporting material is designed with inherent flexibility through its netted structure. This dynamic structure can adapt to vibrations and pressure changes without losing its ability to maintain air gaps. The flexible netted structure allows the supporting material to dynamically respond to operational conditions while consistently providing the necessary support for air gap formation, ensuring reliable performance under varying conditions.

AI summary
A speaker system that includes a speaker unit, a cabinet, a plurality of protruding materials, and a gas adsorbing material. The cabinet forms a chamber at a backside of the speaker unit. The plurality of protruding materials are formed inside the chamber and connected to the cabinet. The gas adsorbing material is supported, in a space, by the plurality of protruding materials. Accordingly, it is possible to easily increase a contact area between the gas adsorbing material and the space theresurrounding.
