AI Technical Summary

Technical Problem

Traditional lampshades have limited functionality, poor noise suppression, especially in terms of low- and high-frequency noise absorption efficiency. They also lack a connection between decoration and sound absorption functions, resulting in low resource utilization.

Method used

The sound-absorbing panel adopts a layered structure design, including a substrate layer, a porous transition layer, and a colored velvet layer. Combined with a reflective pleated structure and heat dissipation channels, it forms a wide-frequency noise absorption system. The sound absorption effect is improved through the synergistic effect of multiple layers, and the heat dissipation and sound absorption are synergistically achieved through metal reinforcing ribs and airflow guiding ribs.

Benefits of technology

It expands the sound absorption frequency range to 100~4000Hz, with a low-frequency sound absorption coefficient ≥0.6 and a high-frequency sound absorption coefficient ≥0.75, achieving synergistic optimization of decoration and sound absorption functions, and avoiding the decline in sound absorption performance caused by airflow impacting the colored velvet layer.
