Vibration-Proof Sound Box Snap-Fit Assembly With Damping Insert
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional coupling methods for sound boxes, such as those using screws, are labor-intensive and fail to prevent vibration transmission, which affects sound quality.
Innovation Solution
A vibration-proof sound box engagement structure comprising a clasp, a holder, and a vibration-absorption unit made of elastic material, allowing quick assembly and effective vibration absorption between two boards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If screws are used for coupling two boards, then the assembly is firmly retained, but labor and time are consumed
Solution Approach 1:
The patent replaces the traditional screw-based mechanical fastening system with a snap-fit engagement system. The clasp includes clasping arms with elastic portions that engage with corresponding engagement portions on the sound box main body, eliminating the need for screws and enabling quick, tool-free assembly while maintaining firm retention.
2Object-affected harmful factors
If the face cover is assembled onto the sound-box main body by clasping, then assembly is simplified, but vibration from the speaker is transmitted to the face cover
Solution Approach 1:
The patent introduces a vibration damping element as an intermediary component between the speaker and the face cover. This element is integrated into the clasp structure, specifically within the clasping arms, and serves to absorb and dampen vibrations generated by the speaker, preventing their transmission to the face cover while maintaining the simplified clasp assembly design.
Solution Approach 2:
The clasp is constructed using composite materials that combine structural rigidity for firm engagement with vibration damping properties. The elastic portions of the clasping arms incorporate materials or structures that provide both mechanical strength for retention and vibration absorption capabilities, resolving the contradiction between simple assembly and vibration isolation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The engagement structure provides a stable, firmly retained, and vibration-proof assembly that enhances sound quality by absorbing vibrations, reducing noise and improving assembly efficiency.
Implementation Method 1
The vibration-absorption unit is made of vibration-absorbing material, has a main body snugly disposed in the clasping space of the clasp, and has a pair of extension portions protruding from the main body. The extension portions abut the inner wall of the holder.

AI summary
A vibration-proof sound box includes a sound box, a first board unit, a speaker, a second board unit, and an engagement structure having a clasp, a holder and a vibration-absorption unit. The clasp has a base portion connected to the first board unit, two clasping arms extending from the base portion, and a clasping space formed between the clasping arms. The free end of each of the clasping arms is formed with a protruding clasping piece. The holder has an accommodating portion connected to the second board unit, and two clasping holes passing through the accommodating portion. The two clasping pieces respectively engage the two clasping holes. The vibration-absorption unit has a main body snugly disposed in the clasping space, and two extension portions extending from the main body. The two extension portions abut the inner wall of the holder.
