[0002] From an environmental protection perspective, any sound that interferes with people's normal rest, study, and work, as well as any sound that interferes with the sounds they want to hear, is considered noise. Noise is a type of sound that causes irritation or is too loud and harmful to human health. Noise pollution mainly comes from transportation, vehicle horns, industrial noise, construction, social noise such as concert halls, loud speakers, morning markets, and people talking loudly.

[0003] Acoustic panels are an ideal sound-absorbing decorative material. They offer advantages such as sound absorption, environmental friendliness, flame retardancy, heat insulation, thermal insulation, moisture resistance, mildew resistance, easy dust removal, easy cutting, parquetry, ease of construction, excellent stability, impact resistance, independence, and cost-effectiveness. Available in a wide variety of colors, they can meet the needs of various styles and levels of sound-absorbing decoration. Existing sound insulation panels are typically simply bonded together by bonding microporous sound-absorbing panels and aluminum sheets to save costs, resulting in poor sound absorption performance. Utility Model Content

[0004] In response to the shortcomings of the existing technology, the utility model provides an environmentally friendly decorative composite sound-absorbing board, which solves the problem that the existing sound insulation board is usually simply bonded and composited with microporous sound-absorbing board and aluminum board in order to save costs, which has the disadvantage of poor sound-absorbing effect.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: an environmentally friendly veneered composite sound-absorbing panel, comprising a sound-inlet panel layer, a sound-absorbing pipe fixedly connected to the interior of the sound-inlet panel layer, the sound-absorbing pipe being hollow and having a sound-conducting pipe extending through the top, a sound-absorbing panel layer fixedly connected to the top of the sound-inlet panel layer, a surface of the sound-absorbing panel layer having a plurality of sound-conducting holes, a honeycomb core layer fixedly connected to the top of the sound-absorbing panel layer, a sound-absorbing cotton layer fixedly connected to the top of the honeycomb core layer, and an environmentally friendly composite panel layer fixedly connected to the top of the sound-absorbing cotton layer.

[0006] Preferably, the silencer pipe is U-shaped and symmetrically arranged inside the sound inlet plate layer.

[0007] Preferably, the sound guide tube passes through the sound guide hole, and the top of the sound guide tube is flush with the bottom of the honeycomb core layer.

[0008] Preferably, a honeycomb structure is provided inside the honeycomb core layer.

[0010] Preferably, the two ends of the silencer pipe are flush with the two ends of the sound intake board layer.

[0011] The utility model provides an environmentally friendly veneer composite sound-absorbing panel. Compared with the existing technology, it has the following advantages:

[0012] 1. An environmentally friendly facing composite sound-absorbing panel, which protects the internal structure by setting an environmentally friendly composite panel layer, filters out sounds of certain frequencies through the sound-absorbing cotton layer, and forms a nearly closed, enclosed space between the sound-absorbing cotton layer and the sound-absorbing panel layer due to the honeycomb structure set inside the honeycomb core layer, preventing air flow and obstructing sound waves, thereby improving the sound absorption coefficient. The sound passes through the interior of the silencer pipe, which can absorb and eliminate most of the noise. The remaining noise is guided to the interior of the sound-absorbing panel layer by the sound guide pipe in combination with the silencer pipe, so that the remaining noise is completely absorbed.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-4 The present invention provides a technical solution: an environmentally friendly decorative composite sound-absorbing board. It includes a sound-input board layer 1, a sound-absorbing pipe 7 is fixedly connected to the interior of the sound-input board layer 1, the interior of the sound-absorbing pipe 7 is hollow, and a sound-conducting pipe 6 is provided on the top. The sound-conducting pipe 7 is U-shaped. The noise is converted from sound energy to heat energy by friction on the U-shaped sound-conducting pipe 7. A sound-absorbing board layer 2 is fixedly installed on the top of the sound-input board layer 1. The noise passes through the sound-conducting pipe 6 fixedly connected to the inside of the sound-conducting hole 200, so that the residual noise is guided to the interior of the sound-absorbing board layer 2, so that the noise disappears after being absorbed by the sound-absorbing board layer 2. The top is fixedly connected with a sound-absorbing board layer 2, which is used for sound insulation. The sound-absorbing board layer 2 can block most of the noise. Objects have inherent resonance frequencies. When the resonance frequency of the object is different from that of the sound-absorbing board layer 2, the sound insulation effect of the sound-absorbing board layer 2 is better. A plurality of sound guide holes 200 are opened on the surface of the sound-absorbing board layer 2. The top of the sound-absorbing board layer 2 is fixedly connected with a honeycomb core layer 3. The honeycomb structure inside the honeycomb core layer 3 can effectively refract and reflect the emission of sound. The top of the honeycomb core layer 3 is fixedly connected to a sound-absorbing cotton layer 4, and the top of the sound-absorbing cotton layer 4 is fixedly connected to an environmentally friendly composite board layer 5. The sound-absorbing cotton layer 4 is used to generate sound after the object vibrates. Since the sound-absorbing cotton layer 4 has a multi-fiber structure inside, the sound waves will be reflected, superimposed and collided by countless fibers when passing through the sound-absorbing cotton layer 4. After the sound wave energy is converted into heat energy, the sound wave intensity will be weakened. The sound-absorbing pipe 7 is U-shaped and symmetrically arranged inside the sound-input board layer 1, so that the sound can form an approximately closed and enclosed space between the sound-absorbing cotton layer 4 and the sound-absorbing board layer 2 to prevent air flow. The sound guide pipe 6 passes through the sound guide hole 200, and the top of the sound guide pipe 6 is flush with the bottom of the honeycomb core layer 3. The interior of the honeycomb core layer 3 is provided with a honeycomb structure. The environmentally friendly composite board layer 5 is linearly arranged on the surface of the sound-absorbing cotton layer 4 and consists of wavy protrusions. The two ends of the sound-absorbing pipe 7 are flush with the two ends of the sound-input board layer 1.

[0021] When in use, the environmentally friendly composite board layer 5 is provided to protect the internal structure, and the sound of some frequencies is filtered out through the sound-absorbing cotton layer 4. Due to the honeycomb structure provided inside the honeycomb core layer 3, an approximately closed and enclosed space can be formed between the sound-absorbing cotton layer 4 and the sound-absorbing board layer 2, preventing air flow, hindering sound waves, and improving the sound absorption coefficient. The sound passes through the inside of the sound-absorbing tube 7, which can absorb and eliminate most of the noise. The sound guide tube 6 cooperates with the sound-absorbing tube 7 to guide the remaining noise to the inside of the sound-absorbing board layer 2, so that the remaining noise is completely absorbed.

[0022] In this embodiment, an environmentally friendly facing composite sound-absorbing board, among the above components, its own structural features and working principles all adopt existing technologies and will not be described in detail here.
