Sound Box Damping Mount Structure for Vibration Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fixing mechanisms for sound boxes on casings are costly and fail to effectively absorb vibrations, leading to deformation of vibration-absorbing gaskets and transmission of vibrations to other electronic components.
Innovation Solution
A fixing mechanism comprising a first bridging structure on the sound box, a second bridging structure on the casing, a rib structure, and a damping structure with a base, exterior, and interior portions that form an accommodating space for the bridging structures, eliminating the need for screws and providing effective vibration isolation and sound transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screws are used to fix the sound box on the casing, then the sound box can be securely fixed, but the cost increases and vibration absorption is ineffective
Solution Approach 1:
The patent replaces expensive screws with a cost-effective damping structure that achieves reliable fixing. The damping structure is designed as a single-use component that provides both mechanical support and vibration absorption, eliminating the need for expensive fasteners while maintaining fixing stability.
Solution Approach 2:
The damping structure employs composite material design combining rigid portions for structural support and flexible portions for vibration absorption. This composite approach allows the structure to function both as a fixing mechanism and a vibration damper, replacing the need for separate screws and vibration-absorbing gaskets.
2Reliability
If rigid screws are used to fix the sound box, then secure fixation is achieved, but vibration generated from the sound box cannot be absorbed effectively
Solution Approach 1:
The damping structure features different local properties: rigid portions for structural support and connection, and flexible portions for vibration absorption. This local differentiation allows the same structure to provide both secure fixation and effective vibration damping, resolving the contradiction between fixation stability and vibration absorption.
Solution Approach 2:
The damping structure acts as an intermediary element between the sound box and the casing. It mediates the connection by providing both mechanical support (through rigid portions) and vibration isolation (through flexible portions), preventing direct rigid contact that would transmit vibrations.
3Object-affected harmful factors
If vibration-absorbing gaskets are used with screws, then vibration absorption is provided, but the screw cannot accurately lock on the sound box when passing through the gasket
Solution Approach 1:
The patent extracts the vibration absorption function from the traditional vibration-absorbing gasket and integrates it into the damping structure. By removing the separate gasket component, the design eliminates the problem of screws having difficulty locking through deformed gaskets, while maintaining vibration absorption through the flexible portions of the integrated damping structure.
4Object-affected harmful factors
If the vibration-absorbing gasket is deformed by incorrect screw insertion, then the gasket fails to absorb vibration and sound transmits outward
Solution Approach 1:
The damping structure is designed with inherent flexibility and deformation tolerance before assembly. The flexible portions are pre-configured to accommodate assembly variations without failing, providing beforehand cushioning against incorrect insertion. This prevents the gasket deformation problem while maintaining vibration absorption capability.

AI summary
A fixing mechanism for fixing a sound box on a casing is disclosed in the present invention. The fixing mechanism includes a first bridging structure disposed on the sound box and surrounding a speaker of the sound box, a second bridging structure disposed on the casing and surrounding a sound hole on the casing, a rib structure disposed on the casing, and a damping structure installed between the first bridging structure and the second bridging structure. The damping structure includes a base for contacting against the rib structure, an exterior portion disposed on an outer edge of the base for installing inside the second bridging structure, and an interior portion disposed on an inner edge of the base. An accommodating space is formed between the exterior portion and the interior portion for accommodating the first bridging structure.
