Solution Overview

Problem

The challenge in speaker device design is achieving high adhesion strength between the edge and frame while reducing the size of the device without compromising the breadth of the diaphragm and edge, often resulting in difficulties during the production process due to slim connecting members.

Innovation Solution

A speaker device design that incorporates an annular connecting member with a width greater than the edge's outer peripheral region and an inner diameter less than the edge's inner diameter, facilitating easier adhesion and improved connection strength between the edge and frame, while allowing for reduced size without sacrificing sound quality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If the width of the connecting member is reduced to match the reduced adhesion margin, then the speaker device size is reduced, but the adhesion strength and ease of manufacture deteriorate

Engineering Contradiction:

Core Design Contradiction:
Volume of moving objectVSEase of manufacture

Solution Approach 1:

The connecting member is designed with a width greater than the outer peripheral region width, effectively utilizing the radial dimension to provide sufficient adhesion area. This dimensional approach allows the connecting member to extend beyond the edge's outer peripheral region, creating a larger contact area for adhesion without increasing the overall speaker device footprint.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The connecting member's width parameter is specifically set to be greater than the outer peripheral region width, while its inner diameter is set to be less than the outer peripheral region inner diameter. This parameter configuration creates a geometric relationship that ensures both sufficient adhesion area and proper fit within the speaker device structure.

AI summary

Provided is a speaker device with which high strength can be obtained for the connection between an outer peripheral region of an edge and an attachment part of a frame, even while reducing a size of the speaker device without sacrificing a breadth of a diaphragm and the edge. This speaker device (10, 20, 30) includes: a diaphragm (11, 21) that radiates sound; an edge (12, 22, 32) arranged in an outer periphery of the diaphragm (11, 21); a frame (13, 33) arranged in an outer periphery of the edge (12, 22, 32) and including an annular attachment part (13a, 33a) connected to an outer peripheral region (12b, 22b, 32b) of the edge (12, 22, 32); and an annular connecting member (17) arranged between the outer peripheral region (12b, 22b, 32b) and the attachment part (13a, 33a) and adhered to the outer peripheral region (12b, 22b, 32b) and the attachment part (13a, 33a). A width of the connecting member (17) is greater than a width of the outer peripheral region (12b, 22b, 32b), and an inner diameter of the connecting member is less than an inner diameter of the edge (12, 22, 32).
