The frame 1 (referring to Fig. l, 1A and 1B) is a rectangular frame. The periphery of bottom plate of the frame is formed by lateral plates connected as a rectangular frame. The outer edge of each lateral plate is formed with a groove 11. A plurality of concave seats 12 are installed at the interior of the bottom plate.
The panel 3 (see Fig. 3, 3A and 3B) is a rectangular plate for matching to the frame 1. Many adjacent small tapered holes 31 are formed thereon. The small tapered holes 31 have respective tilt portions 32 at the surface of the panel 3.
The plurality of larger and smaller sound absorbing barrels 2 (see Fig. 2A, 2B, 2C and 2D) have round taper shapes (or any camber shape without any tip portions, or straight barrel shapes).
The height thereof is suitable for the height of the lateral plates of the frame 1. The diameter of the bottom thereof is suitable for the concave seats 12 at the bottom plate of the frame 1, and the inner edge at the top thereof has a tilt portion 21 . The bottom thereof is formed with a smooth convex portion 22.
By aforesaid structure, a plurality of large and small sound absorbing panels 2 are arranged in the frame and then is covered by the panel 3 so as to be formed as an sound absorbing panel 100 so that the wave of noise is guided into the sound absorbing barrels 2 in the frame 1 through the small tapered holes 31 on the panel 3, and thus remained therein circularly without being dispersed and therefore, the noise is reduced.
As shown in Fig. 8, a plurality of the sound absorbing panels s can be assembled by a grid structure 4 from the grooves 11 at the outer edges of the frame 1 so as to be formed as a larger sound absorbing panel 100 for absorbing sound more effectively.
Furthermore, as the unit of a sound absorbing panel 100 has a larger area, it can not be shaped by a single module. Therefore, the present invention provides a simple way for assembly the sound absorbing panel 100, which is convenient, and practical, and thus the cost can be decreased. The frame 1 and panel 3 can be machined individually. Moreover, the frame 1 is formed by lateral plates, and the plurality of large and small sound absorbing barrels 2 are formed by small molds so as to be mass-produced.
Then, the sound absorbing barrels can be arranged in the frame 1 spaced in an equal distance. Then, they are welded by high frequency welding. Then the panel 3 is covered and is welded by high frequency welding. Therefore, a sound absorbing panel 100 with a large area is achieved.
