Tweeter Support Snap-Fit Assembly for Vehicle Speakers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing loudspeaker support arrangements for vehicles require tools and fixing means, such as screws or rivets, for assembly, which complicates the process and increases time and costs.
Innovation Solution
An annular-shaped loudspeaker support with a circular groove and a tweeter support featuring abutment and clipping means, including elastic arms and transverse ribs, allows for snap-fastening without additional tools or fasteners, facilitating simplified assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional fixing means (screws, rivets) are used to assemble tweeter support on loudspeaker support, then the connection strength and reliability are improved, but the assembly complexity and time consumption increase
Solution Approach 1:
The patent replaces the traditional mechanical fastening system (screws, rivets requiring tools) with a snap-fit mechanical system. The tweeter support features clipping arms with elastic elements that engage with corresponding grooves in the loudspeaker support, creating a tool-free assembly process while maintaining connection reliability through the elastic retention force.
Solution Approach 2:
The elastic clipping arms are designed to automatically engage with the loudspeaker support grooves when the tweeter support is positioned correctly. The elastic elements provide self-retaining force that secures the assembly without requiring additional fastening operations or tools, making the assembly process self-completing.
2Reliability
If traditional fixing means (screws, rivets) are used to assemble tweeter support on loudspeaker support, then the connection strength and reliability are improved, but the device complexity and number of components increase
Solution Approach 1:
The patent merges the support structure with the fastening function into a single integrated design. The tweeter support body includes integrated clipping arms that directly engage with the loudspeaker support, eliminating the need for separate fasteners, brackets, or additional connecting components.
Solution Approach 2:
The patent extracts the fastening function from the traditional separate fastener components and integrates it directly into the tweeter support structure itself. The clipping arms are formed as integral parts of the tweeter support, removing the need for external screws, rivets, or separate mounting hardware.
3Reliability
If traditional fixing means (screws, rivets) are used to assemble tweeter support on loudspeaker support, then the connection strength are improved, but the manufacturing cost and economic efficiency worsen
Solution Approach 1:
The patent changes the physical state and material properties of the support components, making them elastic and flexible rather than rigid. The clipping arms are designed with elastic elements that can deform during assembly and then retain the tweeter support through elastic recovery, enabling a different manufacturing approach that eliminates tooling for fastener installation.
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
This solution enables tool-free and time-efficient assembly of tweeter and loudspeaker supports, resulting in economic savings and improved mounting efficiency.
Implementation Method 1
cooperating clipping means for fixing the tweeter support on the loudspeaker support, the circular groove comprising on its lateral edges openings for receiving, in the final position of the assembly of the tweeter support, protruding heads of the elastic clipping arms

AI summary
The arrangement has a speaker support (2) that is in a form of annular shape, where a part of an exterior surface of the support has a circular groove (3) for receiving a mounting foot (4) of a tweeter support (1). An internal surface of the circular groove and a surface of the mounting foot have stop units and clipping units cooperating for fixation of the tweeter support on the speaker support. Transversal grooves are formed at a base of the circular groove. The tweeter support and the speaker support are made of plastic material.
