Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

In view of the problems in the prior art, the present invention provides a module device for diffuse reflection of sound, which is described in detail below with reference to the accompanying drawings.

As shown in fig. 1-2, in the sound diffuse reflection module device provided in the embodiment of the present invention, the cloth sound-transmitting decorative layer 1, the solid wood decorative plate 4, and the back plate 5 form a closed space, and the closed space is an all-solid wood low-resonance cavity structure, so that the resonance characteristic of the cavity can be effectively reduced. A frame body 2 is arranged in the closed space, a cloth sound-transmitting decorative plate 1 is arranged right in front of the frame body 2, and a back plate 5 is arranged at the back of the frame body 2; the frame body 2 is internally connected with a grating/diffuse reflection curved surface 3, and the grating/diffuse reflection curved surface 3 adopts a grating type composite structure, so that the energy conversion efficiency of the reflection wave can be greatly enhanced; and the high-quality environment-friendly sound absorption glass fiber cotton can absorb sound. Solid wood decorative plates 4 are fixed on the upper and lower sides of the frame body 2 and are mutually connected. The grid/diffuse curved surface 3 dimensions were 240 thickness by 1100 width by 600 height.

The interior of the cloth sound-transmitting decorative plate 1 is of a grating diffuse reflection structure, the frame body 2 is a multilayer plate, the solid wood decorative plate 4 is of New Zealand pine, the grating/diffuse reflection curved surface 3 is a fiberboard, and glass fibers are filled in the hollow part of the grating/diffuse reflection curved surface 3.

The working principle of the utility model is as follows: the sound waves enter from the cloth sound-transmitting decorative layer 1, and in the wood structure device, the cavity resonance is effectively reduced. The grating/diffuse reflection curved surface (fiber board) 3 adopted by the utility model disperses the reflected sound waves, so that sound focusing is avoided, and the energy efficiency ratio of the direct monitoring sound is improved; the grid structure absorbs sound waves better. Wherein, the filled high-quality environment-friendly glass fiber also plays a certain sound absorption role. The utility model is a set of composite multifunctional acoustic units, which can solve the problem of sound focusing reflection in the listening sound field.
