Screwless Speaker Mounting Assembly with Elastic Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly of speaker modules in portable electronic devices is cumbersome and has a low yield due to the need for precise positioning and multiple screws for sealing, which complicates the manufacturing process and increases costs.
Innovation Solution
A mounting assembly that uses a combination of metal and plastic cavities with an elastic member to securely fix the functional box without screws, utilizing the elastic member's high repulsive force for sealing and fixing, simplifying the assembly process and reducing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple screws and precise positioning fixtures are used to fix the speaker box, then the sealing between the sound hole and speaker box is improved, but the assembly process becomes cumbersome and productivity decreases
Solution Approach 1:
The mounting assembly merges the positioning and sealing functions into a single integrated structure. The elastic member simultaneously provides positioning (through its deformed state) and sealing (through its contact with the sound hole), eliminating the need for separate screws and fixtures, thus improving productivity while maintaining sealing quality
Solution Approach 2:
The elastic member performs self-positioning and self-sealing through its elastic deformation. When the speaker box is inserted, the elastic member automatically deforms to accommodate the box and then rebounds to provide both positioning force and sealing contact, requiring no external fixtures or screws, thereby simplifying the assembly process
2Reliability
If multiple screws and positioning fixtures are used, then the sealing and fixing of the speaker box is improved, but the manufacturing complexity and cost increase
Solution Approach 1:
The mounting assembly combines multiple functions (positioning, fixing, and sealing) into a single elastic member structure. This integrated design eliminates the need for multiple separate components (screws, fixtures, positioning features), reducing manufacturing complexity while maintaining fixing stability through the elastic member's inherent mechanical properties
Solution Approach 2:
The invention extracts and eliminates unnecessary components (screws, positioning fixtures, screw holes) from the traditional speaker box mounting system. The essential functions are retained and achieved through the elastic member's deformation and rebound characteristics, simplifying the overall structure and reducing manufacturing steps
3Stability of the object's composition
If screws and positioning fixtures are used, then the speaker box is securely fixed, but the assembly process requires complex fixtures and has low yield
Solution Approach 1:
The elastic member provides self-fixing through its elastic properties. When the speaker box is inserted into the mounting assembly, the elastic member deforms to accommodate the box and then rebounds to securely hold it in position, achieving stable fixation without requiring complex external fixtures, thereby improving assembly yield
Solution Approach 2:
The invention utilizes the elastic member's ability to change its physical state (deformed state during insertion, rebounded state for fixation). This parameter change allows the same component to serve both as a guide during assembly and as a securing mechanism afterward, simplifying the process and improving yield

AI summary
A miniaturized mounting assembly for the acoustic elements in an electronic device includes a housing and a functional box having function elements therein. The functional box is fastened in the housing. A chamber is defined on the housing. An elastic member is fixed on an inner end of the chamber. One end of the functional box abuts against the elastic member, and the other end of the functional box abuts against another end of the chamber away from the elastic member, thereby integrally fixing the functional box in the chamber. An electronic device having the mounting assembly is also provided.
