DETAILED DESCRIPTION OF THE DEVELOPMENT This invention relates to electronic appliances,
guitar amplifiers, radios. Structure and other speaker cabinet tension on the front plate of the
speaker cabinet such as stereo equipment 6 '0' '' 6 pc As shown in Figure 1, the speaker pock 20
-. '110.1, No: ↓ □' In front of 'i' and to protect the speaker 's i' and the K grill net 2 made of
Saran, for example, is installed with a certain gap 3 between it and the speaker box 2, as shown
in FIG. 2, a gap 3 is formed for the aesthetic appearance between the 5 side edge of the front
plate 4 also serving as a buckle plate and the open end face 1 a of the speaker box 1 It is
attached to the stepped part S by using Tucker · Keeping adhesive. In this way, the front panel 4
with the grille net 2 tightened is provided on the inner periphery of the end 1 and the end face of
the speaker box 1 il? We fixed it with the screw $, but in this case it was not visible from the
front), but in the direction of the arrow A, it is between the speaker box 1 and the front side 1 [4,
see ssp'it 15 Lilnet * t - m plane [In case of the head of Takka 6 to fix 4K or adhesive In the case
of adhesive, the cutting line which is not the busy line of the grill net or the entanglement of the
grill net can be seen and the body is extremely soft and stiff - In order to eliminate the
drawbacks, it is intended to make the t-th 20 · 2 s - '<s) like, characterized in that the inner
peripheral end face of the opening of the speaker box is engaged with the peripheral edge of one
side face of the front one face plate A second stepped portion 5 is provided on the outer

peripheral end face of the opening portion of the speaker box so that a space between the first
stepped portion and the front plate can be formed and a grill having one surface Klk of the front
plate The edge of the net is passed over the first stepped portion on the other side By setting the
second stepped portion provided on the even number of the speaker box evenly to the first
stepped portion, the edge of the grill net is forcibly brought into tension along the first stepped
portion ORK 10 , In which the edge of the grill net and the attachment means can not be seen
from the gap constituted by the front plate and the first and second stepped portions of the
speaker box, Is shown in 15111. The grill net mounting structure of this invention is shown in
FIG. As shown in FIG. 4, a frame member 1412 for configuring the speaker box U at the
peripheral edge of one side face of the front plate U also serving as a baffle plate) A stepped
portion ν slightly wider than the plate thickness is added to the ith shudder- F (a) -5 = 1 setting,
speaker box The second stepped portion 17 having a width corresponding to the length lI
between the outer peripheral edge 1 of the opened end of the day and the front plate U And a
front end portion U provided on the front plate U at a circumferential edge thereof at a position
somewhat larger than the film width of the first stepped portion ν.
It is almost constituted by a mute mounted configuration for face plate mounting. On the front
face of the front plate 11, grill net 19 is to be caught, grill nets 19) Mecca nod or adhesive on the
rear side beyond the edge of the first stepped part 12 at the edge of 19. As shown in Fig. 3,
install this front plate as the speaker box opening end of the intestine VhK 31. When pushed in
the state shown in FIG. 4, the protruding edge part projecting to the opening end t by the second
stepped part 17 bunches 15 in the grill net Ha obliquely above the first stepped part S The
oblique portion 19m is deformed so as to follow the first stepped portion 12 by utilizing the
elongation of the material and in this state the front plate 11 is passed through the open end mK
11 of the speaker box intestine and the setscrew n Mechanically fix with. th。 Therefore, the
joining portion 1121 c of the front plate n and the speaker box intestine and the voice of the
voice (4) are formed by the polymerization of the first and second stepped portions 12. 171, and
a gap pus which constitutes aesthetic accents on the outer periphery is constituted However,
since the attachment portion of the grille net bladder hides inside the speaker box and does not
appear in the gap, it is not 5 when the beauty is impaired. Although both stepped parts are
formed by cutting out the front plate and the frame member of the speaker box, it is necessary to
adjust it to separate parts by considering not to cause acoustic hindrance K Even if the front plate
1 and the baffle plate are made separately from each other, even if the front plate 1 and the
baffle plate 2 are separately constructed, the same configuration is obtained as the speaker box
4, As described above, according to the present invention, the first stepped portion which the
inner circumferential end face of the opening portion of the sponge 15-car box holds is formed
on the peripheral edge of one side face of the front plate or the front face plate also serving as a
baffle plate, A second stepped portion is provided on the outer circumferential ground surface of
the opening portion of the speaker box so that a certain gap can be formed in the edge portion of
the grill net which is weired so as to cover the J axis of the front plate; ~ Side (s) Fixed to the

other side beyond the first stepped part , The second stepped portion provided on the speakerbossox conduit is engaged with the first stepped portion to fix both, so that the circumferential
step stepped portion of the grill net is hidden inside the speaker box Exposure through the gap. ,
The aesthetic appearance is not impaired and the grinding net which is skewed over the first
stepped portion is made to follow the first stepped portion at the protruding edge portion
constituted by the second stepped portion The tension of the grill net covering the front plate
increases so that 1 () obsession is eliminated by the other, and the grill net tension can be easily
performed, and so on,
