DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a loudspeaker
protection net plate to be detachably attached to a front surface of a speaker box, which is
provided with an excellent feeling equivalent to that of a cloth so as to obtain a free shape which
can not be obtained by cloth . Conventionally, as a net plate detachably attached to the front face
of a speaker box, as shown in FIGS. 1 (a) and 1 (b), a cloth 2 stuck on the surface of a frame 1
made of wood or resin It is most common. This is to express a sense of quality by the unique
feeling of the cloth 2. On the other hand, on the other hand, the surface of the cloth 2 is
necessarily flat, and it has become a disadvantage that it can not be made into other shapes. On
the other hand, as shown in FIGS. 2 (a) and 2 (b), it is also known to use a punching plate 3
having fine through holes 3 a in a sheet metal as a net plate. This has the advantage that a
considerably free shape such as a flat surface on the surface and a slightly curved one can be
obtained by a metal mold for sheet metal, but on the other hand, since the surface treatment
method is limited, cloth It is a disadvantage that luxurious feeling like the one like it is difficult to
come out. This is the same also in the case of using wire gauze or molding grill. The present
invention provides a speaker protection net plate for solving such a conventional problem. An
embodiment of the present invention will be described below with reference to FIG. FIG. 3 shows
a punching plate similar to that shown in FIG. 2 used as a substrate 4 and implanted at the
surface of the substrate 4, that is, a portion not having the through hole 4a. As shown in FIG. 3
(C), this implanted hair is coated with the adhesive 5 beforehand on the surface of the substrate
4 and cloth is preliminarily coated with fine .lambda.1. ; It can be realized by a method of

spraying the fibrous material 6 or the like. 1 "'In this way, an arbitrary shape can be obtained
depending on the degree of freedom 3 of forming of the base 4, and the surface substantially
obtains a texture equivalent to that of the cloth, so it is easy to feel a sense of quality . Note that a
wire mesh or a molding grill may be used as the base 4. As described above, according to the
present invention, since the surface of a base such as a punching board, wire mesh, molding grill
or the like is implanted, it is possible to obtain free formability and a high-grade feel similar to a
fabric at the same time.
