the same or corresponding parts.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT The present invention relates to a
loudspeaker apparatus, which improves a loudspeaker grill plate mounted on the front surface of
a 41 rc. Conventionally, as shown in Fig. 1 fL, the loudspeaker grill plate is affixed with a wooden
outer frame fi + 14 cloth like net) and fixed with inner stopper rivet (3) inside the outer frame
(dish) by 11 L tacker and fixed (4) fitting detachment hole tarc provided at the speaker main
body (5114 by 4) so
as to detach (2) to the speaker main body (6) provided at the inner four
corners of the outer frame + 11. Such a conventional speaker grill board requires a difficult
processing technique such as cloth-like net tensioning, attachment to the outer frame of a
detachable part, and requires many assembling steps and assembly time. Repair and repair is
problematic in case of damage, deformation, sagging etc. during production, distribution, use.
The diversity of life, individualization and the book's taste of books have drawbacks such as not

being able to respond to requests such as changes in material, color, pattern of speaker grill
which is VC combined. In order to eliminate the above-mentioned drawbacks, the present
invention provides needle-like protrusions on the inner side of the speaker grill outer frame,
latches the protrusion 1C cloth-like net, and also provides holes at the four corners of the outer
frame, The detachable part is fitted to both of the holes to fix the speaker grill plate to the
speaker body 4. Below, detailed explanation 1c of the present invention will be explained
according to the illustrated embodiment VC. 2 to 7, (1) is a loudspeaker grille outer frame, inside
Ka needle-shaped protrusions (η and needle-like holes (alternatingly plural (3 ) Is provided. (9)
has the same shape as this outer frame A, and a plurality of needle-like protrusions + 71 and
needle-like holes (8) are provided alternately, respectively, and the outer frame beams 111 and
the outer frame B 19) Shaped projection () of the outer frame B (9)) and the needle-like hole (8)
of the outer frame n (19) and the needle- ) And the needle-like hole (8) of FIG. 5 are engaged with
each other as shown in FIG. 5. Detachment part mounting screw holes provided at the four
corners of the outer frame M 111 and the outer frame B 19), the outer frame joining stop hole
provided on the tsiq speaker main body + 51, 1 lIl is the speaker grill plate and the speaker body
5), and (2) is a cloth net. In such a case vc, cloth-like nets (2 needle-like protrusions of outer
frame A (1)) are hooked and attached, and outer frame B (9) is pinched and fixed. Thereafter, the
screw holes al (C attachment / detachment component 1 provided at the four corners of the two
outer frames A, B, (1), and toH are screwed and fixed.
Figures 6 and 7 show this state. This kind of fitting is fitted to the speaker main body (6) (4) by
fitting the attachment detachment part 1 of the speaker main body (5) attachment detachment
hole + 61 rc. FIG. 8 shows another embodiment of a speaker grill plate, in which cloth-like nets
(2) are stuck so as to wrap around the outer frame (1) and are hooked with needle-like
projections tnvL. FIG. 9 is a view in which the outer frame B (191) of the outer frame (1) is
screwed with the butting attaching and detaching part II. FIG. 10 shows still another embodiment
of the speaker grill plate, in which two cloth-like nets (wrapping the outer frames A and B, fi +, +
91 separately and butting them together to form a detachable part This state is shown in Fig. 11
with threaded -9. Fig. 12 shows a speaker grille board composed of one outer frame + 11, one
cloth-like net (wrapped around the outer frame A (1) with a fibula and having a needle-shaped
protrusion + 'nrc hook attached A needle-shaped protrusion (η) of the outer frame (1) of the
outer frame (1) is inserted into the speaker body C, and a recess groove U (C is inserted so as to
join it and the detachable part-O is inserted from the outside of the speaker grill outer frame
Speaker body (Ω hole tar is fitted and fixed. FIG. 13 is a perspective view showing the joined
state. (5) Since the present invention is constructed as described above, it is easy to obtain clothlike net tensioning processing because the outer frame can be made of resin (W) (more integral
molding is possible and dimension accuracy and strength are easily obtained) , It can solve such
as it takes labor and time to assemble conventional assembly and assembling time. Also, since it
is possible for users to freely assemble and use, it is possible to omit the steps such as net frying
and fixing the speaker grill board to the speaker body, packaging and shipping as parts, dirt on

the production side, Damage, deformation, etc. are less likely to occur, and K, V during use It is
easy to respond to these events, such as parts exchange and service. In addition, it is easy to
disassemble, clean and replace, easy to adjust such as slack generated during use. You can enjoy
various diversity of speaker grill according to your taste, and also have the effect of choosing
your favorite fabrics and using them for use.
