Speaker Edge Connection Structure for Strong Adhesion in Compact Frames
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing speaker devices face challenges in achieving high connection strength between the outer peripheral region of the edge and the attachment part of the frame while reducing the size of the device without sacrificing the breadth of the diaphragm and edge, particularly when the adhesion margin is slim, such as less than 1 mm.
Innovation Solution
A speaker device design that incorporates an annular connecting member with a width greater than the outer peripheral region and an inner diameter less than the edge, ensuring improved adhesion and alignment with the frame, thereby enhancing production process ease and connection strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the width of the connecting member is increased to improve adhesion strength, then the connection strength between the edge and frame is improved, but the device size increases
Solution Approach 1:
The connecting member is designed with a width greater than the outer peripheral region width, extending in the radial dimension to provide adequate adhesion area. This dimensional extension allows the connecting member to bridge the gap between the edge and frame effectively, achieving strong connection without increasing the overall device volume in the axial direction.
2Volume of moving object
If the adhesion margin is reduced to decrease device size, then the device size is reduced, but the production process becomes difficult and connection strength decreases
Solution Approach 1:
The connecting member serves as an intermediary component between the edge and the frame. By having a width greater than the outer peripheral region, it provides a stable intermediate structure that facilitates the adhesion process. This intermediary design ensures that even with reduced adhesion margin, the production process remains feasible and the connection maintains adequate strength.
3Area of moving object
If the width of the outer peripheral region is reduced to maintain diaphragm breadth, then the device size is controlled, but the adhesion area for the connecting member is reduced
Solution Approach 1:
The connecting member is designed as a separate component with its own width dimension independent of the outer peripheral region width. By segmenting the adhesion function into this dedicated connecting member structure, the design allows the outer peripheral region to maintain its optimal width for diaphragm performance while the connecting member provides sufficient adhesion area through its extended width.

AI summary
A speaker device includes: a diaphragm that radiates sound; an edge arranged in an outer periphery of the diaphragm; an attachment part facing an outer peripheral region of the edge; and a connecting member held between the outer peripheral region of the edge and the attachment part, wherein the connecting member is adhered to at least one of the outer peripheral region or the attachment part, and the edge has a curved portion convexly curved on a sound radiation side.
