DETAILED DESCRIPTION OF THE PROBLEM This Noto is embedded in a ceiling or a wall surface,
etc., with respect to the ceiling or wall structure of the part where the force should be embedded,
"1 × attachment of the embedded speaker = tt, in particular with respect to tt" The installation of
embedded speakers improved to have high flexibility and adaptability relates to the device.
Conventionally, this type of embedded speaker is generally used as a device as shown in FIG. 1
for example. 1, the device has a configuration in which the U-shaped metal fitting 1 and the cup
member 2 are connected by a screw 3 and a butterfly nut 4, and this is connected to a speaker
provided in advance in a plate-like member 6 constituting a ceiling or a wall surface Il + is fixed
to the embedding hole 5, as shown in the figure, and then the speaker 7 is mounted in such a
manner that its elastic engaging piece 8 engages with the slit 9 of the cup member 2. However,
in the above-described conventional embedded speaker attachment, in the case where the
speaker is to be embedded, that is, in the ceiling concept, the plate-shaped member on the wall
has a step and its thickness is extremely different, There was a drawback that involved great
difficulty in attaching the speaker. In other words, the metal fitting for installation tilts, making it
difficult to reliably fix and support the speaker. 20 Accordingly, the present invention aims at
eliminating the drawbacks of the conventional device (2) and the like as described above, and
more specifically, it has high flexibility with respect to the structure of the portion where the

speaker is to be embedded It is intended to provide a device with a seated embedded speaker
with wide adaptability. In order to achieve such an object, the installation of the embedded
speaker according to the present invention is characterized in that the device comprises a pair of
at least two divided holes with respect to the opening direction in a shape along the periphery of
the speaker embedded lumen Use edge metal fittings. Each of the I11 metal fittings has a flange
portion formed by bending the lower end thereof outwardly and an ear portion provided with a
screw hole facing the seven rung portions are integrally provided, And a clamping screw is
attached to the 7 - lang portion to fasten the screw around the speaker embedding hole between
the 7 - lung portion and one clamping screw) so that the ud - like member can be clamped I will
explain in detail. FIG. 2 is a perspective view showing an example of the arrangement of the
embedded speaker according to the present invention, in this case being composed mainly of a
set of two brackets 12 and 13. The metal fittings 12 and 13 have a 7-rung portion 14 which is
formed by bending a lower end of the speaker buried hole 21) (3) (4) a two-part cylindrical shape
along the edge and bending the lower end outwardly, And two ear portions 15 formed by
bending a part outward.
A screw hole 16 is provided in the ear portion 15, and a thumbscrew 18 provided with a locking
piece 17 at its tip is attached to the screw hole 16 from above, and on the upper surface of the
bending flange portion 14 The locking pieces 17 of the butterfly screw 18 are diagonally
connected so as to face each other. In order to attach the embedded speaker only to the ceiling or
the wall using such a device, as shown in FIG. 3, firstly, the metal fittings 12 and 13 are inserted
from the outside into the speaker embedding hole 19 previously formed on the ceiling or the
wall surface Insert the butterfly screw 18 in such a way as to sandwich the same edge member
20 of the hole 19 between the seven rung portions 14 and the locking piece 17. In this state, if
the speaker 22 fixed to the front panel 21 is inserted into the hole 19, the engaging portion 23 a
at the upper end of the elastic engaging piece 23 attached obliquely upward and upward to the
curved panel 21 is engaged with the engaging portion 23 a of the metal fittings 12 and 13 It can
engage with the upper end and support the speaker 22. (4) Even if there is a difference in
thickness as shown in the plate-like member 20 constituting the oblique wall surface, the metal
fittings 12 and 13 Is constant with reference to the outer surface of the plate-shaped member 20,
so that no inconvenience as in the conventional case occurs. "As apparent from the above
description of the friend, according to the present invention, since the plate-shaped member is
directly interposed between the seven lance portion and the individual butterfly screw using the
split cylindrical shaped metal fitting , It is possible to attach the speaker easily and reliably with a
simple operation 11 + even in a portion where the thickness of the ceiling or the wall surface is
different, and it is possible to attach the speaker easily and reliably not only to the difference in
thickness but also to the flexibility And it will exhibit wide adaptability. It should be noted that
the number of metal fittings used in the present invention is not limited to one pair but can be
any number of pairs as a matter of course. Needless to say that the shape can also be
appropriately changed according to the shape of the speaker to be embedded .
