Summary:The utility model discloses a novel slit board is mainly as different environment's abatvoix. Package rubbing board material base member, the slit recess of distribution on the panel base member slit recess bottom sets up or the plane face of cracking set up sound absorption slit structure on the face of cracking. Sound absorption slit structure is for setting up the slit of inclined plane lower part, perhaps sound absorption slit structure is including setting up the slit and the setting on inclined plane upper portion are in the slit of inclined plane lower part, perhaps sound absorption slit structure is including setting up the slit and the setting on inclined plane upper portion are in a plurality of micropores of inclined plane lower part. The slit width is 0.01~0.1mm, diameter of the micropore is 0.01~0.1mm. Novel slit board has the sound absorption slit structure of various ways, can satisfy different environment's demand. Acoustic absorption performance is good, weather resistance is strong. Adopt th
