AI Technical Summary

Technical Problem

Existing cones have insufficient fatigue resistance under long-term, high-intensity vibration, making them prone to deformation and damage. Furthermore, their support structures lack flexibility, making it difficult to adjust them according to different audio signals and vibration states, and causing inconvenience in installation and maintenance.

Method used

It adopts a multi-part collaborative support structure, including a limiting hoop, a central ring, a support rod, and an external base. Combined with a layered coating design, it utilizes a carbon fiber coating to improve fatigue resistance, achieves uniform stress distribution through an adjustable support structure, and features a convenient connection and disassembly design.

Benefits of technology

It improves the durability and stability of the cone, ensures stable sound quality output, and reduces the difficulty and cost of installation and maintenance.
