Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless otherwise specified.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

The present invention is further described with reference to fig. 1-4.

A sound insulation decorative plate comprises an upper plate body 1, a lower plate body 3 and a sound insulation core 2 positioned between the upper plate body 1 and the lower plate body 3; the lower plate body 3 is provided with a connecting block 5, and the upper plate body 1 is provided with a connecting groove 4 matched with the connecting block 5. The sound insulation core 2 comprises a sound insulation frame 2 and a sound attenuation cavity 2; the silencing cavity 2 is internally provided with a silencing area 62 and a central silencing pipe 61; the silencing area 62 is symmetrically distributed at the left side and the right side by taking the axis of the central silencing pipe 61 as a symmetrical line; the silencing area 62 consists of a transverse silencing pipe 621 and a longitudinal silencing pipe 622; the silencing cavity 2 is filled with silencing cotton. Wherein horizontal hush pipe 621, vertical hush pipe 622 and center hush pipe 61 all are the screw thread column structure, and the hush pipe of screw thread column structure changes the frequency of the sound through hush pipe, and then subducts the decibel of sound in the transmission process, improves the syllable-dividing effect of acoustic celotex board, and hush pipe is hollow square gypsum post. Due to the matching use of the microporous structure of the gypsum and the product thereof and the hollow square gypsum column, the sound can be better reduced after passing through the gypsum column, so that the sound insulation board has excellent sound insulation performance. Connecting block 5 and the spread groove 4 of looks adaptation, improve the holistic stability of connection between plate body 1 and the lower plate body 3, because the axis that the amortization district 62 used central amortization pipe 61 is the symmetrical line, left and right sides symmetric distribution makes the amortization pipe can evenly distributed on sound-proof rack 7, and then the all-round decibel to sound is cut down, the cooperation of amortization cotton and amortization pipe is used, the decibel of the sound through the acoustic celotex board has been reduced, make the sound after passing the acoustic celotex board can be accepted, thereby reduce the injury of sound to the human body. The silencing cotton is safe and free of dust, and the upper plate body 1 is tightly connected with the lower plate body 3, so that the silencing cotton in the sound insulation core 2 between the upper plate body 1 and the lower plate body 3 cannot easily run out.

Further, the upper plate body 1 and the lower plate body 3 are both provided with a placing cavity 9 for placing the sound insulation core 2. The placement chamber 9 is provided so that the soundproof core 2 can be completely positioned between the upper plate body 1 and the lower plate body 3 and so that the soundproof core 2 is not easily damaged.

Further, the inner wall of the placing cavity 9 is covered with an elastic layer 8. So that certain buffer force exists between the upper plate body 1 and the lower plate body 3 and the sound insulation core 2, and the sound insulation core 2 is protected to a certain extent.

Further, a polyurethane foam layer is provided on the inner wall of the sound-proof frame 7. The polyurethane foam layer can also play a certain sound insulation effect, and then the whole sound insulation effect of the sound insulation plate is improved.

Further, an adhesive is provided on the upper plate 1 and the lower plate 3. The use of the adhesive enhances the stability of the integral connection between the upper and

lower plate bodies

1 and 3 and the soundproof core 2.

The above is only the preferred embodiment of the present invention, and is not intended to limit the present invention, and the skilled in the art can carry out the common changes and replacements within the technical solution of the present invention.
