[Action]

 The speaker net of the present invention is a plastic mesh sheet 3 made of a synthetic resin similar to the cabinet with a large number of small holes arranged regularly in a zigzag pattern. It is heat-sealed so as to cover the sound holes, and the speaker body mounted on the front or at the corners or sides of the front end of audio audio equipment such as a stereo or TV, or the sound holes for speaker transmission is installed. It can be firmly attached and fixed to the outer frame of the formed cabinet for storing the speaker body.

Since the speaker net of the present invention is formed by the flexible plastic mesh sheet 3, it is suitable for covering the speaker sound holes arranged at the corners on the front side of the cabinet of the audio equipment. Is particularly effective, and it is relatively easy to obtain a curved surface with an appropriate curvature according to the degree of bending elasticity of the plastic sheet held by the speaker net, and by adjusting the hardness of the speaker net appropriately, the curved surface can be adjusted. It is possible to set a reliable holding force and deformation resistance against external force.

The speaker net of the present invention uses a plastic mesh sheet 3 that does not use metal as a material and is easy to form into a three-dimensional shape, and the mesh sheet 3 has small holes 2 in a zigzag pattern. Since the structure is arranged in a rectangular shape, compared with a mesh sheet in which small holes 2 are arranged in a rectangular lattice pattern, an impermeable sheet is overlaid on the mesh sheet 3 and subjected to forming processing such as heating vacuum and pressure forming. When the mesh sheet 3 is processed into a three-dimensional shape, the array distortion of the small holes 2 due to the three-dimensional stretching of the mesh sheet 3 is inconspicuous.

In addition, depending on the color tone combination of the mesh sheet 3 and the cabinet 11 or the color tone combination of the mesh sheet 3 and the gauze-like mesh fabric 21 superposed, in a monotone, duotone, or multitone. Various color tones can be developed, and the existence of the speaker S main body on the back side of the mesh sheet 3 can be made invisible by coloring the mesh sheet 3 or the gauze mesh fabric 21 with a light absorbing color tone. By superimposing the fine mesh gauze mesh cloth 21 on the surface of the mesh sheet 3, it is possible to finish the appearance of the speaker net with a delicate texture by the gauze mesh cloth 21 in appearance.
