Speaker Mounting Structure Using Integrated Locking Member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing speaker mounting structures require a dedicated mounting tool and metal tapping screws, increasing the number of parts, weight, and complexity, especially in onboard applications, and involve cumbersome mounting processes.
Innovation Solution
A speaker mounting structure that uses a flange portion with a penetration hole and a locking member with a connecting portion that can be cut by hand tools, allowing for direct locking into mounting holes without additional tools or screws, reducing the number of parts and steps required for mounting and simplifying the process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a dedicated mounting tool and metal tapping screw are used to mount the speaker, then the mounting strength and reliability are improved, but the number of parts, weight, and device complexity increase
Solution Approach 1:
The patent combines the mounting tool and fastening function into a single integrated locking member. The locking member includes both the locking portion that engages with the mounted member and the connecting portion that attaches to the speaker frame, eliminating the need for separate mounting tools and tapping screws. This merging reduces the number of parts while maintaining mounting reliability through the unified structure that performs both locking and fastening functions.
Solution Approach 2:
The locking member is designed with multi-functionality, serving as both the mounting tool and the fastening element. The locking portion provides the mounting function by engaging with the mounted member, while the connecting portion provides the fastening function by attaching to the speaker frame. This universal design allows a single component to replace multiple specialized parts, reducing complexity while maintaining reliability.
2Reliability
If a dedicated mounting tool and metal tapping screw are used to mount the speaker, then the mounting strength and reliability are improved, but the weight increases
Solution Approach 1:
By merging the mounting tool and fastening element into a single locking member, the patent eliminates the weight of separate components. The integrated structure uses material more efficiently, reducing total mounting weight while maintaining the necessary mounting strength through the combined locking and connecting functions in one piece.
3Reliability
If a dedicated mounting tool and tapping screw are used to mount the speaker, then the mounting strength is improved, but the ease of manufacture deteriorates due to increased complexity
Solution Approach 1:
The patent simplifies manufacturing by combining multiple parts into one integrated locking member. Instead of manufacturing separate mounting tools and fasteners, the single locking member can be produced in one molding or machining process, reducing manufacturing complexity while maintaining mounting strength through its integrated structure.
Solution Approach 2:
The locking member is segmented into functional portions (locking portion and connecting portion) that can be designed and manufactured independently in terms of function, yet produced as a single integrated component. This segmentation of functions within a unified structure simplifies manufacturing by allowing the entire assembly to be produced in one process while maintaining the functional benefits of distinct sections.
4Reliability
If multiple steps including locking the mounting tool, engaging the speaker, and screwing the tapping screw are required, then the mounting strength is improved, but the productivity deteriorates due to increased time consumption
Solution Approach 1:
The patent merges multiple mounting operations into a single action. The locking member is designed so that inserting and securing it simultaneously accomplishes both the locking of the speaker to the mounted member and the fastening of the speaker frame, eliminating the need for separate screwing operations. This reduces mounting time while maintaining strength through the integrated locking and fastening mechanism.
5Reliability
If multiple steps including locking the mounting tool, engaging the speaker, and screwing the tapping screw are required, then the mounting strength is improved, but the ease of operation deteriorates
Solution Approach 1:
The patent combines multiple operational steps into a single easeful operation. The locking member integrates the mounting tool function and fastening function, allowing the user to complete both locking and fastening in one action rather than performing separate steps. This simplifies the operation while maintaining mounting strength through the unified structure that performs both functions simultaneously.

AI summary
A speaker includes a flange portion, a locking member and a connecting portion. The flange portion includes a penetration hole. The locking member is arranged in the penetration hole and includes a locking portion that protrudes from the flange portion and is to be locked in a mounting hole in a prescribed size. The connecting portion connects an end surface facing the penetration hole with the locking member and is to be cut by a hand tool.
