DETAILED DESCRIPTION OF THE INVENTION This invention relates to a speaker grille plate
mounted on the front of a loudspeaker system. In general, the speaker grille is a cloth or saran
net fixed to a wooden frame and has a shape as shown in FIGS. 1 and 2. For the convenience of
explanation, we use the saran net below. Figure 1 and Figure 2 are perspective views showing a
conventional speaker grille board, and 11jl is shown in Table 1fi. FIG. 2 shows a weir surface. In
the figure, (1) is a speaker grill plate in which a saran net (2) is stretched in a wooden frame (3) (needle) 703Q, (4) is a reinforcing bar of the wooden frame (3), (5) is a speaker grill Parts for
attachment / detachment and wooden frame reinforcement, (6) are parts for attachment /
detachment of speaker grille. (7) shows the nameplate, and (8) shows the overlap of the saran net
and its rumbling. As described above, in the conventional speaker grille plate, the saran nets of
the four corner surfaces are overlapped, resulting in sticking and unfolding. There are a large
number of parts, 9 assembly man-hours, 9 dimensional accuracy, etc., and processing techniques
with high accuracy are required. From the point of the strength of the speaker grille, there are
many limitations on the thickness, width, reinforcing bars and the like of the wooden frame, and

there is a drawback that the efficiency is deteriorated due to the increase of the sound surface. In
order to eliminate the above-mentioned drawbacks, this invention uses a screw or the like to
attach an external end surface type member in which a nameplate and a component for attaching
and detaching a speaker grill are arranged on a speaker grill plate with a saran net stretched on a
wooden frame It prevents tortoise, sagging, and entanglement of saran nets on the four corners
of the speaker grille, and enables the reinforcement of two structural parts to be obtained. (2) An
embodiment of the present invention will be described below with reference to the drawings. 8 to
7 show outer surface end surface members of the speaker grille plate according to the present
invention, FIG. 3 is a rear view of a seed member (9), FIG. 4 is a plan view, and FIG. 5 is a front
view B, FIG. 6 is a side view, and FIG. 7 is a front view with nine to ninety-two strokes in FIG. In
the figure, reference numeral (9) is a seed member, ?O is a mounting hole for attaching the
speaker grille attaching / detaching part (6), and (6) is a seed frame (9) of the present invention
attached to a wood frame covered with a saran net. It is a screw hole. Fig. 8 is an i? saponal view
in which the speaker grille attaching / detaching part A-ha product (6) is attached to the seed
member (9), and Fig. 9 is a speaker on the seed member (9) Fig. 8 is a perspective view showing
an assembling means for mounting the grille detachable part (6) as shown in Fig. 8 and fixing the
speaker grille plate (sealed from the back of the coffin with a screw (2)) Figs. 1 to 12 show the
speaker grille plate in a good condition completed by attaching 81 members (9), Fig. 10 is a front
view, Fig. 11 is a side view, Fig. 12 (3 ) Is a rear view.
The speaker grille plate configured in this manner has 81st part-81.degree. ????? As
described above, since the speaker grille plate of the present invention is fixed by at least one
side all fence member of the outer end face such as a saran net or cloth stretched in a wooden
frame, the saran nets of four corner corners of the speaker grille plate are fixed. It is possible to
prevent the fabric from being wrinkled and to prevent it from becoming loose, and also to
prevent the unfolding and to obtain a decorative effect with accents on the upper and lower
houses. Also, since the seed member is generally made of metal. There is a reinforcing effect of
the speaker grille plate, and there is no need to use after the reinforcement as in the conventional
one, so it becomes thin, and the sound masking surface is reduced, and an efficient speaker grille
plate can be obtained. is there. In the above embodiment, cloth, saranne 7, i, tr,. There is no one
character ri (4). Moreover, although the covering member which covers the outer end surface of
a grill board is provided in the upper and lower end part, a required effect can be acquired even
if it is only one side.
