Speaker Cabinet Mounting With Dampers to Prevent Inclination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing speaker cabinet designs for electronic devices cause vibrations that can lead to inclination and collisions with internal components, resulting in noise and increased manufacturing and assembly costs due to insufficient damping support.
Innovation Solution
A speaker cabinet design that uses two fixing structures to support a damper on the cabinet body, reducing inclination and noise by mitigating vibrations through flexible first and second fixing structures and dampers, which are securely positioned on the housing to absorb and counteract vibrations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple bolts with dampers are used to fix the speaker cabinet, then the vibration cushioning is improved, but the manufacturing cost and assembly time increase
Solution Approach 1:
The patent combines multiple fixing functions into a single integrated speaker cabinet structure. The cabinet body itself incorporates the fixing functionality that would otherwise require separate bolts and dampers, reducing the number of components while maintaining vibration cushioning effectiveness.
Solution Approach 2:
The speaker cabinet body is designed to serve multiple functions simultaneously: it provides structural support, vibration damping, and self-fixing capabilities. This multi-functionality eliminates the need for separate fixing components, reducing both manufacturing cost and assembly complexity.
2Reliability
If a damper is slipped on a bolt for fastening, then the vibration absorption is improved, but the speaker cabinet may incline towards unpredictable direction and contact internal components
Solution Approach 1:
The fixing and vibration absorption functions are merged into the cabinet body structure itself. The cabinet body incorporates integrated fixing structures that maintain stable positioning while providing vibration damping, eliminating the instability caused by separate bolt-and-damper assemblies.
Solution Approach 2:
The cabinet body is designed with pre-integrated vibration cushioning structures that are built-in before assembly. This beforehand cushioning ensures stable positioning and prevents inclination issues that occur with post-assembly damper attachment.
3Reliability
If the cabinet body is fixed with sufficient support structures, then the vibration mitigation is improved, but the manufacturing cost increases
Solution Approach 1:
The patent merges the support structures into the cabinet body itself, eliminating the need for separate fixing components. This integration reduces the total number of parts, lowering manufacturing costs while maintaining effective vibration mitigation through the unified structure.
Solution Approach 2:
The cabinet body is designed as a multi-functional component that provides both structural support and vibration mitigation simultaneously. This eliminates the need for additional dedicated support structures, reducing manufacturing complexity and cost while maintaining reliability.

AI summary
The present disclosure relates to a speaker cabinet for electronic device, which is disposed in an electronic device and comprises a cabinet body, two first fixing structures, two dampers, and two second fixing structures. The damper is disposed on two side surfaces of the cabinet body through the two first fixing structures and fixed on the electronic device through the two second fixing structures for fixing the cabinet body in the electronic device. The cabinet speaker according to the present disclosure adopts only two fixing structures to fix the cabinet body to the electronic device. The damper is also used for mitigating the vibrations generated by the cabinet body. In addition, the two fixing structures are used for supporting the damper for avoiding inclination of the cabinet body towards an unpredictable direction and colliding the housing of the electronic device and its internal components.
