Description

Technical Field

[0001] The utility model relates to a felt board, in particular to a sewn cavity type felt board. Background Art

[0002] Felt board is a board made of fiber material with softness and sound absorption performance. It is usually used for sound absorption, sound insulation, heat preservation, filling and other aspects. In the production process of felt board, the fiber material is compressed into a board shape, and its density and thickness can be adjusted through different processing techniques to meet different usage requirements. Due to its good sound absorption performance and easy processing, felt board is widely used in construction, automobile, furniture and other fields:

[0003] Ordinary felt boards may have limited effect in shock absorption. Ordinary felt boards are usually single structures and cannot be flexibly adjusted according to specific needs. They have poor anti-collision performance. Therefore, there is an urgent need for a stitched cavity felt board.
