AI Technical Summary
Technical Problem
Existing ultra-thin carbon fiber cones lack a dustproof structure at the cone outlet, allowing dust to enter and affecting sound quality. Furthermore, the poor sealing effect can easily lead to sound distortion.
Method used
An annular positioning block and an annular sealing ring are installed in the annular slot of the speaker frame. The annular sealing ring made of corrosion-resistant rubber works in conjunction with the annular positioning block to provide a seal at the sound outlet of the speaker cone. A dustproof net is installed on the positioning block to prevent dust from entering.
Benefits of technology
It effectively prevents dust from entering the cone, maintains sound quality, and prevents sound distortion through a sealed structure.
