DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a speaker
mounting apparatus capable of eliminating wiring processing of lead wires and performing work
on parts. Conventional mounting devices of this type are mounted on a dowel 2 protruding on
the back surface of a cover 1 of a television receiver, for example, as shown in FIG. 1 (a), ( ) via
a screw 3 to a speaker The main body number is fixed and the lead wire 6 is soldered to the back
surface of the speaker main body 4 via the insulating plate 5 or by using a fixing metal fitting
(not shown). However, with this conventional device, it is very difficult to handle the lead wires
etc, and due to this food safety requirement I and 7 / were extremely difficult to install the food /
food . Meanwhile, in audio, electrical appliances, etc., wiring processing is adopted in which
electronic components of a capacitor and a resistor ring are inserted on a board and fixed by
soldering, so that rationalization of wiring processing and improvement of workability are
attempted However, if such wiring processing can be applied to the mounting of the speaker, it
would be desirable to rationalize the installation work of the spike force. SUMMARY OF THE
INVENTION The present invention has been made in view of the above-mentioned problems, and
it is an object of the present invention to provide a speaker holding fixture which has a
conductive speaker holding metal supported by a conductive plate, fixing the speaker holding
metal to a speaker frame, , It is possible to easily install the speaker and to improve the
workability of this type of mounting work, and to provide a speaker lining attachment. DETAILED

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of the present
invention will be described with reference to the drawings. In FIGS. 2 to 4, reference numeral 7
denotes a speaker main body, and an elongated insulating plate 9 made of Bakelite is arranged at
the lower end portion of the speaker frame 8 with a eyelet 2 - 1 It is caulked and fixed. In this
case, the eyelet 10 having a polygonal shape such as a quadrangular shape or the like is used to
prevent rotation of the insulating plate 9. The speaker body 7 is attached by conductive speaker
holding metal fittings 111C disposed at both ends of the insulating plate 90. As shown in FIG.
That is, a through hole for inserting the tinsel cord 13 is formed at the lower end portion of the
speaker frame 8 via an eyelet 14 protruding from the speaker cone 12, and at both ends of the
insulating plate 90, a prismatic An insertion hole 15 is formed, and the tinsel wire u 7 inserted in
the eyelet 14 and the - - - - - - - is fixed by soldering 16. In this case, it is desirable that the nut 14
is integrally formed at the tip end of the holding metal fitting 11, and by forming the flange fi 11
on the holding metal fitting 11, the rigidity of the holding metal fitting U is increased, It is
desirable to use the positioning stopper of the above-mentioned structure.
In addition, the river is a conductive plate of the steel plate ring disposed on the lower surface of
the substrate 17, (2) is a soldering in which the tip of the holding metal fitting 11 inserted in the
through hole of the base plate 17 is fixed to the conductive plate cloth, 3 - 21 The yoke
accommodates the magnetic circuit disposed on the back surface of the speaker body 7. In the
speaker mounting apparatus according to the present invention constructed as described above,
when installing the speaker, the insulating plate 9 is attached by caulking the two pieces 10 on
the lower end portion of the speaker frame 8, and the eyelet disposed at the distal end of the
speaker holding fitting 11 14 is inserted into the through hole of the insertion hole V of the
insulation plate 9 and the tinsel wire 13 is inserted into the eyelet 14 and then the tip of the nod
14 is caulked and the tinsel wire 13 14 are soldered 16 and the speaker body 7 is attached to the
tip of the speaker holding metal fitting 11. Thereafter, the lower end of the speaker holding metal
fitting 11 is inserted into the through hole formed in the base plate 17 and the conductive plate
18, and the lower end of the speaker holding metal fitting 11 is soldered to the conductive plate
18 and fixed. Therefore, in this series of mounting operations, since wiring of the lead wires is
not required and electrical conduction between the speaker body 7 and the conductive plate 18
is realized via the speaker mounting metal fitting 11, And can be done promptly. FIGS. 4 and 5
and 6 show another embodiment of the present invention, in which speaker holding metal
fittings 21 ', 21' having a short leg length as compared with the speaker main body 7 and having
a conductive function, and kite support members And the speaker holding metal fitting 4 serving
as the speaker holding metal fitting 4 serving as the speaker holding member, so that the
strength of the supporting structure is strengthened, so that the other portions are substantially
the same as the above-described embodiment, Corresponding components are denoted by the
same reference numerals, and description thereof will be omitted. INDUSTRIAL APPLICABILITY
As described above, according to the present invention, since the speaker body is attached to the
conductive speaker holding bracket supported by the conductive plate and the wiring of the lead

wires as in the past is eliminated, it is easy to request the safety standard It is possible to cope
with this, and 1 it is possible to perform this kind of mounting work rationally, and it is possible
to improve workability. In addition, since the speaker main body is practically installed by the
speaker holding metal fitting, no special processing is required for the speaker main body, and
no fixing metal fitting for this is required, so the number of parts and the manufacturing process
are reduced, It is possible to provide an inexpensive speaker mounting rack as well as the phase
5. Furthermore, since the speaker body is occupied on the board, there is an effect such that the
installation space can be effectively utilized.
