Speaker Grille Attachment System with Concealed Fastening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing speaker grille attachment systems fail to provide a secure and aesthetically pleasing method for attaching the speaker grille, as visible screws detract from the appearance and can weaken the fastening due to wear from shocks and vibrations.
Innovation Solution
A speaker grille attachment system using clamp hole pieces, a cover member made of elastic material, and a speaker gasket to conceal fastening components, ensuring secure attachment while enhancing aesthetics by hiding screws and screw holes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If screws are used to fasten the speaker grille, then the speaker grille can be securely attached to the speaker, but the screws are visible and detract from the aesthetic appearance
Solution Approach 1:
The visible screws are extracted or removed from the final assembly by using a cover member that conceals them. The fastening function is maintained through the clamp hole piece and gasket system, while the aesthetic requirement is satisfied by hiding the screws behind the cover member.
Solution Approach 2:
A cover member is introduced as an intermediary element between the viewer and the fastening components. This cover member serves as a mediator that preserves the aesthetic appearance while allowing the underlying screw fastening system to maintain structural integrity.
2Device complexity
If small screw heads are used for fastening, then the device complexity is reduced, but the fastening strength is insufficient to withstand shocks and vibrations
Solution Approach 1:
The fastening system is segmented into multiple functional components: clamp hole pieces for positioning and clamping, gaskets for sealing and distribution, and screws for fastening. This segmentation allows each component to perform its specific function optimally, with the gasket distributing load across a larger area to enhance fastening strength without increasing overall complexity.
Solution Approach 2:
The fastening system uses composite construction combining rigid components (clamp hole pieces, screws) with flexible components (gaskets). This composite approach allows the rigid parts to provide structural integrity while the flexible gasket material distributes stresses and enhances the overall fastening strength against shocks and vibrations.
3Ease of operation
If screw holes are provided on the speaker grille rim, then the grille can be fastened to the speaker, but the holes weaken the grille structure and allow foreign objects to potentially enter
Solution Approach 1:
The problematic screw holes in the grille rim are eliminated. Instead, the clamp hole pieces are positioned to clamp onto the outer rim surface, extracting the need for penetrating holes while maintaining the attachment function. This preserves the grille's structural integrity and foreign object protection.
Solution Approach 2:
The gasket acts as a flexible element that can deform to accommodate the clamp hole pieces and distribute fastening forces without requiring rigid holes in the grille. This flexible approach maintains the grille's structural strength while enabling easy attachment.

AI summary
A speaker grille attachment system for a loudspeaker securely and easily attaches a speaker grille to the speaker as well as attains an improved aesthetic effect by hiding components used for the attachment. The attachment system includes a plurality of fastening members, a plurality of clamp hole pieces each having a hole for inserting the fastening member therethrough, a plurality of openings formed on an outer rim of the speaker grille, a speaker gasket having a plurality of openings each receiving the clamp hole piece and the fastening member, a speaker frame or cabinet having a plurality of fastening means for attaching the speaker grille, and a cover member for covering an area of the outer rim of the speaker grille thereby making the components for the attachment invisible.
