Abstract

The invention provides an acoustic reinforcing material block as well as a manufacturing method and application thereof. The acoustic reinforcing material block is prepared by taking components including a porous material, a binder, a pore-forming aid or gas, a filler and water as raw materials and adopting a foaming freeze-drying process, a freezing foaming process or a sintering forming process, the acoustic reinforcing material block is internally provided with at least three stages of pore channels, the first-stage pore channels comprise micropores of the porous materials, the second-stage pore channels comprise pore channels formed between the porous materials, between the porous materials and the filler and between the filler and the filler, and the third-stage pore channels comprise cavities formed by pore-forming aid or gas. When the acoustic reinforcing material block provided by the invention is filled in a loudspeaker resonant cavity of the electronic equipment, the volume of the loudspeaker resonant cavity can be virtually increased, so that the loudspeaker can achieve better sound quality under the condition of smaller volume, and has more excellent sound performance.
