Low-noise reinforced cabinet with local porous honeycomb structure

The invention relates to a local porous honeycomb structure low-noise reinforced cabinet, which comprises a cabinet body and a rear plate, and is characterized in that the rear plate is fixedly connected with the rear side of the cabinet body; the cabinet body is of a sand casting integrally-formed structure, and porous conical sound absorption pit structures are densely distributed in the positions, located on the middle rear portion of the left side and the middle rear portion of the right side, of the inner wall of the cabinet body. The rear plate is of a pressurized seepage casting integrally-formed structure and comprises an outer flat plate layer and an inner sound absorption structure layer, and the inner sound absorption structure layer is of a foaming honeycomb sound absorption structure; and the porous conical sound absorption pits at the middle rear parts of the left side and the right side of the cabinet body and the foaming honeycomb sound absorption structure at the inner side of the rear plate
