Speaker Rear Cover With Integrated Connection Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing speaker rear covers have a single structure that is limited in functionality and applicability, making it difficult to integrate multiple functions such as electric contact conduction, cable fixation, and screw fixation, due to the limitations of stamping raw materials and processes.
Innovation Solution
A speaker rear cover design featuring a rear cover body with a connection assembly that includes a conductor contact, a C-shaped limiting device, and a connection hole, allowing for multiple functions like electrical conduction and cable fixation, with the connection assembly being made of metal and manufactured through stamping for increased complexity and integration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single steel sheet is used for the rear cover, then the structure is simple and manufacturing is easy, but it cannot realize complex structures such as electric contact conduction, cable fixing, and screw fixation
Solution Approach 1:
The patent merges multiple functional structures (electric contact conduction, cable fixing, screw fixation) into a single integrated connection assembly that is stamped from one piece of metal sheet. This allows the rear cover to achieve complex functionality while maintaining manufacturing simplicity through a single-stamping process.
Solution Approach 2:
The connection assembly is designed as a multi-functional component that simultaneously provides electrical contact conduction through conductive structures, cable fixation through dedicated fixing structures, and screw fixation through appropriate mounting features. This universal design allows one component to fulfill multiple functions that would traditionally require separate parts.
2Adaptability or versatility
If multiple structures are led out from a local position of the rear cover, then multiple functions are achieved, but the stamping process and raw material are limited and cannot support such complexity
Solution Approach 1:
The patent segments the rear cover into two main parts: a simple rear cover body and a separate connection assembly with multiple functions. This segmentation allows the connection assembly to be independently optimized for multi-functionality while the rear cover body remains simple and easy to manufacture, thus resolving the conflict between functional integration and manufacturing ease.
Solution Approach 2:
Multiple functional structures are merged into a single connection assembly that can be produced through one stamping process. The design ensures that all necessary structures (conductive paths, cable fixing features, screw mounting points) are integrated within this one component, making it manufacturable through standard stamping techniques without requiring excessive material complexity.

AI summary
The present invention discloses a speaker and a rear cover therefor. The rear cover comprises a rear cover body whose one side is provided with a first connection portion; and a connection assembly provided with a first surface and a second surface which are connected with each other. A contact is formed by extending and bending the first surface, and is provided with a conductor. A connection hole is further formed in the first surface. A limiting device and a second connection portion are arranged on the second surface; and the cross section of the limiting device is C-shaped. The connection assembly is connected to the first connection portion of the rear cover body through the second connection portion. The contact is configured to conduct the speaker with the outside. The connection hole is configured to fix the speaker or conduct the speaker with other components.
