DETAILED DESCRIPTION

[0036] The technical scheme in the utility model embodiment will be described clearly and completely below with the drawings in the utility model embodiment.

[0037] For example, Figures 1-14As shown, the utility model provides a kind of sound-absorbing board, including sound insulation board 1, sound insulation frame 2, the sound insulation frame 2 is fixed on the sound insulation board 1 and is jointly enclosed to form the filling cavity 21 for filling sound insulation material, this structure design provides space for filling sound insulation material, enhances sound insulation effect, the sound insulation board 1 is uniformly distributed with several sound insulation holes 11, the diameter of the sound insulation hole 11 is same, and the pitch of adjacent sound insulation hole 11 is same, by adjusting the diameter of the sound insulation hole 11, perforation rate is further improved the sound insulation effect of the sound insulation board 1.

[0038] Specifically, the sound insulation board 1 is metal material, usually adopts steel plate, steel plate has good sound insulation effect, when using, when the sound wave of emitted sound meets the sound insulation board 1, part of sound wave is reflected back by the surface of the sound insulation board 1, part of sound wave is transmitted to sound insulation material by the sound insulation hole 11, sound wave is conducted to sound insulation material, sound wave vibration causes the vibration of molecule or fiber inside sound insulation material, generates friction and consumes sound wave in the form of viscous resistance, to realize noise reduction and sound insulation function, and because the reflected sound wave is less, so the echo produced in the sound insulation board 1 is small or zero, realizes effective sound insulation.

[0039] Specifically, perforation rate is one of important factors influencing sound insulation effect of sound insulation board, by actual detection, the perforation rate of the sound insulation hole 11 in the embodiment is 70%-75%.

[0040] Further, the aperture size of sound insulation hole 11 directly influences the absorption effect of sound insulation board 1 to different frequency sound waves, smaller aperture has better absorption effect to high frequency sound wave, and larger aperture has better absorption effect to low frequency sound wave, the diameter D2 of sound insulation hole 11 adopted in the embodiment is 3-6mm, this range can cover a certain range of frequency, provides more balanced sound insulation and sound absorption performance.

[0041] Further, as shown in the drawing, Figure 3 The hole distance D1 between the sound insulation hole 11 in the embodiment is 2-3mm, compact hole distance helps to scatter incident sound wave, reduces direct propagation of sound wave, thereby reduces the penetration of noise, and helps to improve the absorption capacity to high frequency sound wave, sound wave can more easily enter hole and be absorbed by sound insulation material, the sound insulation hole 11 is circular array, this design provides a regular and beautiful appearance.

[0042] It should be noted that the above-mentioned perforation rate, aperture and hole distance are data obtained through many experiments, and better sound insulation effect can be realized.

[0043] As shown in the drawing, Figures 4-7As shown, the utility model also provides a sound insulation room, including a sound absorption board and house body 4, the house body 4 includes inside wall 41 and inner top wall 42, the sound absorption board is evenly paved on inside wall 41 and inner top wall 42, make the sound absorption board enclose in the inside of house body 4,

[0044] As Figure 5 As shown, the inside wall 41 is equipped with the door mouth 411 that communicates outward, the door mouth 411 is equipped with the door frame 5, the inside and outside end surface of door frame 5 is equipped with inner door 7 and outer door 3 in proper order to realize the double-layer sound insulation at door mouth 411, the outer door 3 forms the closed space with house body 4.

[0045] Because the gap between the inner door 7 and the door frame 5, sound can be leaked from the door gap or other connections, so that the sound insulation effect is weakened, therefore the outer door 3 is arranged at the position corresponding to the inside wall 41 and the inner door 7, by forming a closed space between the outer door 3 and the inner door 7, the possibility of sound leakage through the door gap can be significantly reduced, effectively blocking the propagation of sound, thereby enhancing the overall sound insulation effect, by setting the outer door 3, external impact can be prevented, the safety of the overall structure is improved.

[0046] As Figure 8 As shown, the inner door 7 and the outer door 3 are respectively hinged to the opposite end faces of the door frame 5, by designing the door frame 5 as the connecting structure of the outer door 3 and the inner door 7, the stability and structural integrity of the entire sound insulation room are enhanced, and the close cooperation of the three further reduces the leakage of sound through the door gap or other connections.
