Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional loudspeaker vibration systems using multiple resin layers or silicon rubber membranes face issues with non-uniformity, distortion, and low sensitivity due to the transition between the rigid dome part and the silicon rubber membrane.
Innovation Solution
A loudspeaker vibration system with a diaphragm comprising a rigid dome part, a silicon rubber membrane, and a plastic support, where a convex or concave bent ring part is positioned on the silicon rubber membrane with a controlled spacing between the dome part and the bent ring part, and a colloid is applied in the gap to enhance acoustic performance and reduce distortion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rigid dome part is disposed on the silicon rubber membrane to improve acoustic performance, then acoustic performance is improved, but the transition between the silicon rubber membrane and the rigid dome part causes distortion and sensitivity is low
Solution Approach 1:
The patent introduces a bent ring part as an intermediary component between the rigid dome part and the silicon rubber membrane. This bent ring part serves as a transition element that bridges the rigid and flexible components, enabling smooth mechanical transition and reducing distortion while maintaining acoustic performance improvements.
Solution Approach 2:
The patent applies colloid in the gap between the dome part and the bent ring part, changing the physical parameters of the interface region. This parameter change modifies the mechanical properties of the transition zone, reducing distortion and improving sensitivity by optimizing the coupling between rigid and flexible components.
2Measurement precision
If the spacing between the dome part and the bent ring part is reduced to improve sensitivity, then sensitivity is improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent optimizes the spacing parameter to a specific range (0.02-0.2mm) and applies colloid to modify the interface properties. This parameter change approach allows achieving high sensitivity while managing manufacturing precision requirements through material compensation rather than purely dimensional control.
3Object-generated harmful factors
If colloid is disposed in the gap between the dome part and the bent ring part to reduce distortion, then distortion is reduced, but device complexity increases
Solution Approach 1:
The colloid serves as a simple intermediary material that fills the gap between components, providing distortion reduction through material properties rather than complex structural design. This approach reduces distortion while maintaining relatively simple device structure.
