DETAILED DESCRIPTION OF THE INVENTION
First Embodiment
As shown in FIG. 3, a perspective view of the first embodiment of the decoration acoustic board is illustrated. As shown in FIGS. 4 and 5, the longitudinal cross sectional view along A-A of FIG. 3 the decoration acoustic board and transversal cross-sectional view along B-B of FIG. 3 are illustrated. The decoration acoustic board 10b having a substrate 12 first made from solid wood or chip wood, and then processed through fireproof treatment to mix with fire resistant resin; finally, the mixed resin substrate is compressed to form a decoration board. A plurality of guide slots 121 are formed equidistantly on the front of the substrate 12, and the bottom 122 of the guide slots 121 are in the shape of waved form. A plurality of slots 124 spaced equidistantly from one another are distributed on the underside of the substrate 12. A plurality of holes 123 shaped in the same or different sizes are formed through the substrate 12 in communication with both of the guide slots 121 and slots 124.
The width of the guide slots 121 is larger than the slots 124, for example, such as the width of the guide slots is 1.0 cm, and the slots are 0.2 cm. The dimensions and numbers of the guide slots 121 located on the front of the substrate 12, that would affect the function of absorbing sound waves and the decoration of designed patterns thereof. To obtain the balance, the above mentioned dimensions, such as the guide hole 1.0 cm in width, the slot 0.2 cm in width, is the preferred size; while the depth of the guide slots 121 can be designed as deeper or shallower as required. Other than the designed patterns added to the substrate surface, after the sound waves entering into the guide slots 121, can go through the slots 125 by holes 123. Thereby, the sound waves are reflected and compressed within the holes and the slots, the frequency and volume of the sound waves are reduced and absorbed. In other words, the vibration amplitudes of sound waves are buffered within the holes 123 and slots 125. The waved bottom 122 also shows a graceful streamline appearance that results in a preferred acoustic, decorative, pervious to light, and ventilating effect.
The surface of the substrate 12 (not including guide slots 121) can be processed with surfactant, such as applying lacquer to show the original color of the wooden material, a piece of fireproof melamine lamination board 125 or solid wood pasted up on the surface thereof to show the pasted wood material color.
