Abstract

A sound source muting plate comprises a central plate group (2) and clamping plates (4) separately superimposed and adhered to the upper surface and the lower surface of the central plate group (2). The central plate group (2) is formed by one central plate (1) or formed by more than two central plates (1) superimposed and adhered sequentially on a plane. The central plate (1) is a planar plate structure having a through hole (3).

Description

Sound source mute version

[0001] The utility model relates to a sound source mute board which can weaken the sound of a sound source. Background technique

[^^)2] At present, the noise of the city has become a major public hazard in the city. The noise emitted by a large number of power devices has had a major impact on the daily life of the residents. Currently, there is no effective reduction in the power generation device on the market. Noise device.

Summary of the invention

[0003] The object of the present invention is to provide a sound source mute board that can weaken the sound transmission of a sound source. Book

[0004] The purpose of the utility model is as follows: It comprises a single central plate or a central plate group formed by superimposing and bonding a plurality of central plates, the central plate being a flat plate with a through hole, in a single center plate or The two planes of the central plate group are each provided with a splint, and an adhesive is disposed between each plate.

The utility model has the following advantages, which can effectively reduce the noise generated by the power device in the city, and achieve the overall effect of reducing the sound radiation by controlling the volume transmission channel of the sound source.

detailed description

[0011] As shown in Fig. 1~2: The utility model comprises a single central plate 1 or a central plate group 2 formed by superimposing and bonding a plurality of central plates, and the central plate is a plate structure with a flat through hole 3, in a single Each of the two planes of the block center plate or the center plate group is provided with a splint 4, and an adhesive is disposed between each plate. The center panel or the center panel and the splint are combined with a edging package on the side. The edging package protects the center panel from external factors and extends its life.

[12] The inner side wall of the through hole is a rough surface, and the two planes of the splint are also rough surfaces. By setting the inner side wall of the through hole and the two planes of the splint as rough surfaces,

Confirmation Description

Isolation, noise elimination.

[0013] The through hole is a through hole having a diameter of 0.4 to 30 cm, and 9 to 10000 through holes are distributed per 1 m ^{2 of the} center plate. The thickness of the center plate is between 0.5 and 20 cm, and the thickness of the plate is between 0.2 and 0.5 cm. In the range of the above parameters, better isolation and noise elimination can be achieved.

[0014] The present invention will be described below in conjunction with the embodiments:

[0015] Example 1 :

[0016] In the case where the center plate of the present invention is a single piece: The center plate is a plate structure with a flat through hole, and each of the two sides of the single center plate is provided with a splint, and an adhesive is disposed between each plate. The side panels of the center panel and plywood combination are provided with a edging package.

[0017] The relationship between the thickness of a single center plate and the thickness of the splint and the number of through holes and the number of through holes are as shown in Table 1

[0018]

Table 1

[0019] Example 2:

[0020] The utility model is composed of a central plate group formed by superimposing and bonding a plurality of central plates in a plane: the central plate is a plate structure with a flat through hole, and the two plates of the central plate group are respectively provided with a splint, and each plate is disposed between There is an adhesive. The side panels of the center panel and plywood combination are provided with a edging package.

[0021] The relationship between the number of central plates, the thickness of the center plate, the thickness of the splint, and the aperture diameter and the number of through holes of the central plate group composed of a plurality of center plates are as shown in Table 2 (Table 2). Speaking

[0022]

Table 2

[0023] The center sheets of different thicknesses in Table 2 are arranged in a sequence from thick to thick, or arranged in a large to small diameter.
