AI Technical Summary
Existing rubber products have insufficient sound insulation performance, especially in terms of their weak absorption of high-frequency noise, and are inconvenient to install, resulting in limited overall sound insulation effect.
The design employs a multi-layer structure consisting of a dense barrier layer, a porous sound-absorbing layer, and a damping layer. Combined with a wedge-shaped sealing lip, a magnetic positioning strip, and a double-sided adhesive buffer pad, the rubber products are secured by magnetic adsorption and locking screws, achieving stable installation and broad-spectrum noise absorption.
It improves the sound insulation effect of rubber products, covers a wide frequency noise range of 20-4000Hz, improves installation efficiency and fit, and avoids sound insulation gaps.
