Speaker Core With Suspended Diaphragm Folded Ring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for increasing the vibration area of a speaker core lead to a nonlinear problem between the driving force and the amplitude of the diaphragm, severely inhibiting the increase of the speaker's amplitude.
Innovation Solution
The speaker core design includes a diaphragm frame with a ring-shaped structure, where the diaphragm folded ring features a plurality of bent parts circumferentially disposed, with at least one bent part suspended above the diaphragm frame, ensuring a sufficient width of the arc-shaped portion and increasing the effective vibration area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the area of the diaphragm mass is increased to increase the vibration area, then the sound pressure level is improved, but the width of the arc-shaped portion of the diaphragm folded ring is reduced, causing nonlinearity of the suspension system to increase and severely inhibiting large-amplitude application
Solution Approach 1:
The patent utilizes the height dimension by suspending at least one bent part of the diaphragm folded ring above the diaphragm frame. This vertical positioning allows the arc-shaped portion to maintain sufficient width while the diaphragm mass area is increased, as the folded ring no longer occupies horizontal space above the vibration area. This dimensional transition resolves the contradiction by decoupling the area expansion from the width reduction problem.
2Area of moving object
If the width of the arc-shaped portion of the diaphragm folded ring is reduced to accommodate larger diaphragm mass, then the vibration area is increased, but the nonlinear problem between driving force and amplitude is aggravated
Solution Approach 1:
By moving the arc-shaped portion of the diaphragm folded ring into the vertical dimension (suspending it above the diaphragm frame), the patent allows horizontal space to be allocated to the diaphragm mass for increased vibration area, while the folded ring maintains its functional width in the vertical plane. This enables both large vibration area and sufficient arc-shaped portion width to coexist.
Solution Approach 2:
The diaphragm folded ring is divided into multiple bent parts circumferentially disposed, with at least one bent part suspended above the diaphragm frame. This segmentation allows different portions of the folded ring to serve different functions: maintaining structural integrity and providing sufficient arc width, while allowing the diaphragm mass to expand horizontally for increased vibration area.
