[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] An acoustic perforated panel for indoor ceilings includes a ceiling body 1, which includes a ceiling substrate 101. The ceiling substrate 101 includes plywood 1011 with a honeycomb-shaped keel support. Crystalline sound-absorbing fillers 1012 are filled into the honeycomb holes of the plywood 1011, providing sound absorption. Sound-absorbing holes 1013 are formed in the crystalline sound-absorbing fillers 1012, with a hole diameter of 3-5 mm and a hole spacing of 15-20 mm. This creates an acoustic perforated panel based on the Helmholtz resonator principle. When sound waves strike the ceiling substrate 101, some of the sound energy enters the air cavity behind it through the sound-absorbing holes 1013. During this process, air molecules vibrate and rub against the inner wall of the cavity, converting the sound energy into heat energy and dissipating it. Furthermore, the sound-absorbing holes 1013 themselves also have a certain damping effect on the incident sound waves, further enhancing the sound absorption effect. A sound-absorbing cotton felt 105 is provided above the ceiling substrate 101. The thickness of the sound-absorbing cotton felt 105 is 5-7cm, which can significantly improve the sound absorption performance in the low frequency range.

[0026] The ceiling substrate 101 has a layer of sound-absorbing microporous cloth 102 on both its upper and lower surfaces. The micropores on the sound-absorbing microporous cloth 102 have a diameter of 0.3-0.5 mm and a spacing of 2-5 mm. Based on the theory of micro-perforated plates, the sound-absorbing microporous cloth 102 has excellent sound absorption coefficient across the entire frequency range, especially in the low-frequency range, which further improves the sound absorption effect.

[0027] The lower surface of the sound-absorbing microporous cloth 102 located at the bottom of the ceiling substrate 101 is coated with a sound-permeable coating layer 1021, the thickness of which is 2-3 mm. This forms a porous structure on the surface, thereby enhancing sound absorption while maintaining good air permeability.

[0028] The technical solutions in the above embodiments of this application have at least the following technical effects or advantages: The ceiling substrate 101 in this utility model includes a plywood 1011 in the form of a honeycomb keel support to ensure the overall structural strength of the ceiling body 1. The honeycomb holes of the plywood 1011 are filled with crystal bubble sound-absorbing fillers 1012, which play a sound absorption role. The crystal bubble sound-absorbing fillers 1012 are provided with sound-absorbing holes 1013, so that the ceiling body 1 forms a sound hole board. Based on the Helmholtz resonator principle, the sound absorption effect is greatly improved.

[0029] The ceiling substrate 101 has a layer of sound-absorbing microporous cloth 102 on both the upper and lower surfaces. The sound-absorbing microporous cloth 102 has micropores. Based on the micro-perforated plate theory, it has excellent sound absorption coefficient in the whole frequency band, especially in the low frequency part, which further improves the sound absorption effect. The sound-absorbing cotton felt 105 is provided on the upper part of the ceiling substrate 101, which can significantly improve the sound absorption performance in the low frequency band.

[0030] Example 2

[0031] The ceiling base plate 101 has integrally formed support parts 103 on both sides. A shock-absorbing mounting sheet metal strip 104 is connected to the support part 103. Bolt holes are opened on the shock-absorbing mounting sheet metal strip 104. The shock-absorbing mounting sheet metal strip 104 is connected to the ceiling keel by bolts, thereby assembling and fixing the ceiling body 1.

[0032] The bottom of the shock-absorbing mounting sheet metal strip 104 is a dovetail sliding joint 1041, and the support part 103 is provided with a dovetail sliding groove that cooperates with the dovetail sliding joint 1041. The connection and fixing method between the support part 103 and the shock-absorbing mounting sheet metal strip 104 is simple, stable and effective.

[0033] The two sides of the shock-absorbing mounting sheet metal strip 104 are elastic corrugated parts 1042. The elastic corrugated parts 1042 can buffer the vibration caused by the sound wave impact on the surface of the ceiling body 1. The inner cavity of the shock-absorbing mounting sheet metal strip 1044 is filled with sound-absorbing cotton strips 1043 to absorb some of the noise generated by the vibration.

[0034] The support portion 103 on one side of the ceiling substrate 101 is integrally formed with a positioning strip 1031, and the support portion 103 on the other side of the ceiling substrate 101 is provided with a positioning groove 1032 that matches the diameter of the positioning strip 1031. This is used for alignment and assembly when the ceiling body 1 is spliced ​​and arranged, which facilitates positioning and makes the ceiling tightly arranged.

[0035] The technical solutions in the above-described embodiments of this application have at least the following technical effects or advantages: The ceiling base plate 101 of this utility model has an integrally formed support portion 103 on both sides. A shock-absorbing mounting sheet metal strip 104 is connected to the support portion 103. The shock-absorbing mounting sheet metal strip 104 is connected to the ceiling keel by bolts, and then slides between the support portion 103 and the dovetail structure of the shock-absorbing mounting sheet metal strip 104. The installation direction is simple and convenient. The two sides of the shock-absorbing mounting sheet metal strip 104 are elastic corrugated portions 1042. The elastic corrugated portions 1042 can buffer the vibration generated by the sound wave impact on the surface of the ceiling body 1. The inner cavity of the shock-absorbing mounting sheet metal strip 1044 is filled with sound-absorbing filling cotton strips 1043 to absorb some of the noise generated by vibration.

[0036] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
