Description

Decorative composite acoustic board

Technical Field

The utility model relates to an acoustic board, in particular to a decorative composite acoustic board.

Background

The sound absorption material is mainly divided into a micropore type and a fiber type, and the sound absorption material has no essential difference, the sound absorption principle is that a channel (a channel consisting of countless continuous tiny holes or countless fine gaps formed by countless fibers crossed together) capable of entering sound is reserved for sound, but the sound cannot come out once the sound enters, and the sound is drilled into the sound to be punched left and right to hit due to the fact that the channel is too messy and too long, and energy is gradually consumed in the process, so that the sound absorption effect is achieved.

At present, most of decorative composite sound absorption cotton is directly bonded with a base layer or an outer decorative layer, sound is introduced into the sound absorption cotton through a through hole in the base layer or the outer decorative layer for absorption, the bonding area of the sound absorption cotton and the base layer or the outer decorative layer is relatively large, and the sound absorption effect of the sound absorption cotton is reduced. We have therefore developed this and have now proposed a decorative composite acoustic panel.

Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are described herein for the purpose of illustration and explanation and not limitation.

Example (b): as shown in fig. 1, fig. 2, fig. 3, fig. 4 and fig. 5, the present invention relates to a decorative composite sound-absorbing board, which comprises a protective outer frame 1, a bottom plate 2 is disposed at the bottom end of the protective outer frame 1, sound-absorbing cotton 3, a base layer 4 and a decorative layer 5 are sequentially disposed on the top of the bottom plate 2 from bottom to top, a plurality of sound-absorbing holes 6 for absorbing sound are disposed on the decorative layer 5, a plurality of sound-transmitting holes 7 are disposed on the base layer 4, a plurality of supporting mechanisms 8 for supporting the base layer 4 are disposed at the bottom end of the base layer 4, the bottom ends of the supporting mechanisms 8 are fixedly connected to the top end of the bottom plate 2, and by the supporting mechanisms 8, a supporting plate 9 is matched with a supporting rod 10 to support the base layer 4, so as to prevent the gap between the base layer 4 and the sound-absorbing cotton 3 from being large, so that the base layer 4 and the decorative layer 5 are recessed toward the sound-absorbing cotton 3, and prevent the base layer 4 from being directly connected to occupy a large area of the sound-absorbing cotton 3, thereby increased and inhaled cotton 3's usable floor area of sound, promoted and inhaled cotton 3 effect of absorbing sound of sound.

Wherein, a plurality of sound transmission holes 7 are S-shaped, and through the sound transmission holes 7 arranged in the S-shape, partial sound is prevented from being transmitted from the sound transmission holes 7 after the sound enters the gap between the base layer 4 and the sound-absorbing cotton 3.

Wherein, a plurality of sound holes 6 and a plurality of sound transmission holes 7 are arranged correspondingly, so as to avoid that the sound absorbed by the sound holes 6 can not completely enter the sound-absorbing cotton 3 through the sound transmission holes 7.

Wherein, a plurality of supporting mechanism 8 all include backup pad 9, the top of a plurality of backup pad 9 and the bottom fixed connection of basic unit 4, the bottom of a plurality of backup pad 9 all is equipped with three bracing piece 10, the bottom of a plurality of bracing pieces 10 and the top fixed connection of bottom plate 2, through backup pad 9 and the bracing piece 10 that is equipped with, it is great to avoid basic unit 4 and inhale the gap between the sound cotton 3, cause basic unit 4 and decorative layer 5 to inhaling sound cotton 3 sunken, avoided basic unit 4 simultaneously and inhaled sound cotton 3 directly to being connected, it is great to cause to occupy the area of inhaling sound cotton 3, thereby the usable floor area of inhaling sound cotton 3 has been increased, the effect of inhaling the sound cotton 3 and absorbing sound has been promoted.

Wherein, a plurality of backup pad (9) set up respectively between the adjacent two rows that are transverse distribution pass sound hole (7), avoid backup pad 9 to keep out sound and pass through the sound hole 7 and get into in inhaling the sound cotton 3.

Wherein, having seted up a plurality of mounting holes 11 on inhaling the sound cotton 3, a plurality of bracing pieces 10 run through a plurality of mounting holes 11 respectively and are connected with bottom plate 2, avoid bracing piece 10 not directly to be connected with bottom plate 2, cause the stability of backup pad 9 to reduce.

Wherein, inhale cotton 3 of sound and be the design of character cut in bas-relief shape, support basic unit 4 through supporting mechanism 8 to increased and inhaled the usable floor area of cotton 3 of sound, promoted the effect of the absorption sound of inhaling cotton 3 of sound.

Wherein, the base layer 4 is made of plastic material, thereby reducing the production cost.

In operation, the sound that the external world produced gets into sound transmission hole 7 through inhaling sound hole 6, thereby make sound in sound transmission hole 7 towards the right side and put into the gap between basic unit 4 and the sound absorption cotton 3, further, sound gets into the sound absorption cotton 3 from the gap between basic unit 4 and the sound absorption cotton 3, owing to inhale the interior several countless pores of sound cotton 3, sound gets into after inhaling sound cotton 3 because the pore is too messy too long, sound bores to bore to get away from the left side towards the right side and hits inside, in this process consume the energy gradually, the effect of inhaling the sound has been played, through the supporting mechanism 8 that is equipped with, backup pad 9 cooperatees with bracing piece 10 and supports basic unit 4, it is great to avoid basic unit 4 and inhale the gap between sound cotton 3, cause basic unit 4 and decorative layer 5 to the cotton 3 sunken, avoided basic unit 4 and inhale sound cotton 3 direct to being connected simultaneously, cause to occupy the area of sound absorption cotton 3 great, thereby the usable floor area of sound absorption cotton 3 has been increased, the effect of sound absorption cotton 3 sound absorption is promoted.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the utility model. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
