AI Technical Summary

Technical Problem

The coils of existing flat panel speaker diaphragms are prone to breakage during the screen printing process, resulting in short product lifespan and poor sound quality, making it difficult to meet the growing demand.

Method used

It adopts an insulated plastic bracket and hollow hole design, combined with conductive coils and conduction points. The conductive coils are formed on the metal layer through a low-temperature vacuum electroplating process, and the resistance is adjusted by adjusting the cross-sectional area of ​​the conduction points, so as to achieve a simple structure, good sound effect and long service life.

Benefits of technology

It achieves a simple diaphragm structure, good sound production, and long service life, meeting the needs of different products and avoiding the problem of coil breakage.
