Speaker Second Suspension Fixing Ring Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional speakers for mobile devices have low sensitivity and poor acoustic performance due to a limited effective vibration area of the second suspension, which is constrained by a connecting member in the magnetic circuit unit.
Innovation Solution
The speaker design includes a fixing ring connected to the magnetic circuit unit, with the inner peripheral side of the second suspension fixed to an end of the fixing ring away from the yoke, maximizing the width of the second suspension and integrating it with the fixing ring, thereby increasing the effective vibration area and simplifying assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a connecting member is provided to connect the second suspension to the subsidiary magnet, then the magnetic circuit unit is complete and functional, but the width of the second suspension is limited, resulting in small effective vibration area
Solution Approach 1:
The patent merges the connecting member and the second suspension into a single integrated structure. The second suspension is designed to extend directly to and connect with the subsidiary magnet without requiring a separate connecting member, thereby eliminating the spatial constraint that limited the suspension width and maximizing the effective vibration area while maintaining magnetic circuit functionality
2Area of moving object
If the second suspension width is increased to improve effective vibration area, then acoustic performance improves, but the space available in the magnetic circuit unit is insufficient
Solution Approach 1:
The patent optimizes the spatial arrangement by extending the second suspension in a radial direction from the center toward the subsidiary magnet, utilizing the vertical/depth dimension within the magnetic circuit unit. This allows the suspension to achieve maximum width and effective vibration area without increasing the overall volume or footprint of the magnetic circuit unit
3Reliability
If the second suspension is extended to maximize width, then sensitivity and acoustic performance improve, but the structural complexity of connecting it to the magnetic circuit unit increases
Solution Approach 1:
The patent integrates the connection function directly into the second suspension structure itself. The suspension is designed as a continuous element that naturally connects the diaphragm to the subsidiary magnet, eliminating the need for separate connecting members, holders, or attachment mechanisms, thereby reducing structural complexity while achieving maximum extension and optimal acoustic performance
