DETAILED DESCRIPTION OF THE PROBLEM This horn is intended to make it possible to easily
install a speaker when attaching a speaker in close contact with the wall surface of a housing.
Figs. 1 and 2 show an example of a conventional loudspeaker mounting apparatus, in which a
plurality of sound emitting holes 2 are provided in a wall 1 of a housing, a cylindrical body 3 is
formed around the sound emitting holes 2 , And the bosses 4a, 4b, ac +, 4d are provided around
the periphery of the boss 4a-ad by 1s <2nd, and the bosses ea, eb, sc, ad (csb, ad are not shown)
6 attached to it. This attachment means has a disadvantage that acoustic effect is not so good
since a space is formed between the speaker 6 and the wall 1. In order to improve the acoustic
effect, the speaker 6 may be mounted in close contact with the wall 1. In FIG. 3, the speaker 5 is
brought into close contact with the wall 1 and the speakers are pressed by the metal fittings 7a,
7b. ??? 1 и 8 b is a boss and 9 a and 9 b are screws for mounting. This mounting means
requires the mounting brackets ya, yb and must be attached to the bosses B & B by the screws
9a, 9b, which increases the number of components and also the workability of mounting is poor.
SUMMARY OF THE INVENTION Therefore, the present invention is intended to make it possible
to attach a speaker in close contact with the wall of a housing by simpler means, and one
embodiment of the present invention will now be described with reference to the drawings. The
wall of the enclosure, as shown in Fig. 4, Fig. 6, Fig. A plurality of sound emitting holes 11 are

provided at -5, 10. These ribs, -1 - diagonal и) и + g и Yu =; 3- 3- projecting ribs 12a, 12b having a
cross-sectional shape opposite to each other inside the wall 10 on the side of the sound volume
11 . The ribs 12 a, 12 b are integrally formed with the wall 1 </ b> Q such that their tips face the
sound emitting holes 11. Flat plates 13a, 13b having spring properties are installed between the
ribs 12a, 12b and the wall 1o. This flat plate 13a. 13b is made of, for example, 0.3 ? thick
phosphor bronze. 6, the flange portion of the speaker 14 is laterally inserted between the ribs
12a, 12b and the wall 10 and finally inserted between the flat plates 13a, 13b and the wall 10,
and the flat plate 13 & , The speaker 14 is fixed by the spring property of 13b. A stopper 16 is
provided on the wall 10, the position of the speaker 14 is determined, the fasteners 16 a, 16 b
are inserted into the ribs 12 a. 12 a and 12 b through the through holes 1 - ra, 1 rb of the
speaker 14, the installation state becomes more reliable. In this way, the speaker 14 can be
simply and reliably set by "%", "░" ░, ░, ░, ░, ░, 4 in the speaker 14 by specifically providing
the flat plates 13a, .
It is in the stomach. In FIG. 7, the structure on one side of the mounting is indicated by the boss
19, the metal fitting 20. And is constituted by screws 21. The structure of the attachment is
simplified even in only one side compared with the one in FIG. As described above, according to
the present invention, a speaker having a spring property is specially provided, and a speaker
can be attached to the wall of the housing with a simple structure such as projecting a rib having
a cross-sectional shape on the housing , Which improves the workability of mounting.
