[0001]
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a
wiring structure and a wiring method of a coaxial speaker, and in particular, a coaxial diaphragm
of a bass speaker is made of copper foil or the like as in the coaxial speaker previously proposed.
The conductive material is attached to the dustproof damper attached to the inside of the
diaphragm while the conductive material is attached, and the conductive material comprising flat
mesh wire or the like is attached to the dustproof damper. The present invention relates to a
wiring structure and a wiring method suitable for connecting an end portion and an end portion
of a conductive material extending to an outer peripheral portion of the dustproof damper.
[0002]
2. Description of the Related Art As shown in FIGS. 9 and 10, in a coaxial speaker, a high-pitched
speaker 3 is disposed on or near the central axis of the front surface of a diaphragm of a woofer
1 which is a bass speaker. The wiring structure of a coaxial speaker generally used
conventionally will be described with reference to the drawings. In the method of wiring a lead
for inputting an audio signal to the tweeter 3 installed on the front of the woofer 1, They are
roughly classified into two types according to the difference. The first mode is a method of
relaying a tinsel wire 20a to the cone diaphragm 11 of the woofer 1 and wiring a lead wire for
voice signal input to the tweeter 3 with the tinsel wire 20a, as shown in FIG. In the second mode,
as shown in FIG. 10, the lead wire 20 b is led from the terminal 25 for voice signal input of the
woofer 1 and connected to the terminal 31 of the tweeter 3.

[0003]
In the first embodiment, in order to install the tweeter 3 or the squawker on or near the on-axis
of the front surface of the cone diaphragm 11 of the woofer 1, the magnet 21 of the woofer 1,
the top plate 22, and the yoke 23 are provided. It is common to place the support 24 on the yoke
top 23a of the magnetic circuit to be mounted and attach the tweeter 3 to the tip of the support
24. A lead wire for voice signal input is input to the input terminal 31 of the tweeter 3. In order
to connect, a tinsel wire 20a for inputting an audio signal for driving the woofer 1 is drawn as
shown in FIG.
[0004]
The reason for using the tinsel wire 20a as a lead wire for audio signal input is to wire through
the cone diaphragm 11, and since the tinsel wire has very good resistance to amplitude of the
wire itself, it is a wiring material for all the speakers. It is used as.
As the wiring structure, the vicinity of a hole, which is generally called a neck, and the vicinity of
the central slope of the cone diaphragm 11 provided for connecting the cone diaphragm 11 and
the voice coil bobbin 26a to the center of the cone diaphragm 11 A hole 11a, 11b, 11c with a
diameter of about 2 mm for passing the tinsel wire 20a is provided on the rear surface of the
cone diaphragm 11 as shown in FIG. The tinsel wire 20a is led out to the front surface of the
cone diaphragm 11 through the hole 11a, and further led to the back surface of the cone
diaphragm 11 through the hole 11b and wound around the back surface. It is led to the input
terminal 31 of the tweeter 3 through the hole 11c, and the tip of the tinsel wire 20a and the
terminal 31 of the tweeter 3 are wired by means such as soldering.
[0005]
The tinsel wire 20a between the hole 11b and the hole 11c, that is, the tinsel wire 20a disposed
on the back surface of the cone diaphragm 11, is subjected to cone vibration by the adhesive 18
to prevent generation of contact noise at the time of the amplitude of the cone diaphragm 11.
Since it is adhered to the back surface of the plate 11 and the tinsel wire 20a between the hole
11a and the hole 11b is disposed on the surface of the cone diaphragm 11, the lead wire of the
voice coil 26 of the woofer 1, ie, the lower end of the voice coil bobbin 26a The winding start of
the coil wound around the part, the wire extending the end of the winding and the tinsel wire
20a are soldered, covered with the adhesive 18 in the same manner as above, and adhered to the
surface of the cone diaphragm 11.

[0006]
The second embodiment will be described based on FIG. 10 by providing holes 23b and 24a for
wiring in the yoke 23 and the post 24 of the woofer 1, respectively, and lead wires 20b made of
vinyl or the like from the input terminal 25 of the woofer 1. It is led, passed through the holes
23b and 24a, led to the input terminal 31 of the tweeter 3, and the tip end portion of the lead
wire 20b and the terminal 31 are connected by soldering.
Further, the dustproof damper 13 mounted between the cone diaphragm 11 and the column 24
used in the first and second embodiments prevents dust and the like from entering the magnetic
gap of the woofer 1. In order to correspond to the amplitude of the cone diaphragm 11, it is
generally used in the radial direction from the center to the outer periphery of the woven fabric
etc. Concentric corrugations that run in series are provided.
[0007]
However, in such a first embodiment, since the wiring of the tinsel wire 20a in the wiring is
complicated, the wiring operation becomes complicated, and not only the number of man-hours
inevitably increases but also the manual operation can not but be The quality is not stable and
automation is extremely difficult. Furthermore, when the cone diaphragm 11 of the woofer 1 has
a large amplitude, the tinsel wire 20a may resonate to hit the dustproof damper 13 or the like to
generate an abnormal sound, and an appropriate forming of the tinsel wire 20a should be
performed as a countermeasure. It does not.
[0008]
This forming is also extremely difficult to automate, and has to rely on manual work, and has the
disadvantage that the quality is not stable. Further, the necessity of this forming is the same for
the tinsel wire 20a disposed on the back surface of the cone diaphragm 11, and the resonance of
the tinsel wire 20a at the time of large amplitude hits the rear surface of the cone diaphragm 11
and the damper 17 etc. Generate Therefore, this wiring method has the disadvantage that the
quality instability due to the wiring is extremely high. Also in the second embodiment, since the
lead wires 20b are as complicated as the first embodiment, automation is extremely difficult, and
there is a drawback that the quality can not be stabilized due to the necessity of relying on

manual work.
[0009]
We previously proposed a speaker wiring structure to solve such problems. In this wiring
structure, a band-shaped conductive material consisting of a pair of copper foils 14 and the like
is attached to the cone diaphragm 11 of the woofer 1, and the dustproof damper 13 disposed
inside the cone diaphragm 11 is a pair of flat mesh A conductive material consisting of a cocoon
wire (hereinafter referred to as "flat mesh cocoon wire") 12 etc. is mounted, and a strip-like
conductive material consisting of a pair or more of copper foils 26b etc. A terminal 32 is
provided in the vicinity of the top 24 a of the column 24 for mounting and disposing the tweeter
3, and these are disposed at predetermined positions, and the connection portion provided on the
copper foil 26 b of the voice coil bobbin 26 a and the cone diaphragm 11 A flat wire braided wire
connected to the end portion 14a of the copper foil extending to the central portion of the slope
of the cone diaphragm 11 and the outer peripheral portion of the dustproof damper 13 while
connecting the end portion 14b of copper foil extending to the neck portion End of line 1 a to
connect the flat wire tinsel wire 12 extending to the inner peripheral portion of the dustproof
damper 13 and the terminal 32 provided to the support 24 or to extend to the inner peripheral
portion of the dustproof damper 13 The wire mesh wire 12 and the input terminal 31 of the
tweeter 3 are connected. With the above wiring structure, lead wires for inputting an audio signal
to the input terminal 31 of the tweeter 3 installed in front of the woofer 1, that is, tinsel wire
20a, vinyl wire 20b, etc. in the conventional example. Not only is the wiring structure simplified
because there is no lead-in, and it is possible not only to save a great deal of labor in wiring work,
but in this wiring structure, the lead wires for wiring are fixed to the parts constituting the
speaker . Therefore, since the positioning of the end of the lead wire for connecting and wiring
becomes easy, the wiring operation can be automated. As a result, efficient productivity can be
ensured, and the quality of the wiring can be stabilized.
[0010]
[Problems to be solved by the invention] However, when soldering the contact portion between
the short portion 12a of the flat braided tinsel wire attached to the dustproof damper 13 and the
copper foil 14 of the cone diaphragm 11, flat mesh tinsel wire Since 12 is disposed on the back
surface of the dustproof damper 13, the front side of the tinsel wire 12 at the contact portion
with the copper foil 14 of the cone diaphragm 11 disposed on the outer peripheral portion of the
dustproof damper 13 is covered by the dustproof damper As a result, the contact portion must
be soldered while visually checking the contact portion between the end portion 20a of the tinsel
02-05-2019

wire and the copper foil 14, and the contact portion is exposed at the cut portion of the end
portion of the dustproof damper 13. It is necessary to confirm the portion in the thickness
(thickness) direction of the cocoon thread 12 being done. Therefore, it is necessary to solder at a
very limited location where the thickness of the flat wire tinsel wire 12 is about 0.5 mm and the
width is about 6 mm, and some learning is required for visual confirmation and wiring work.
[0011]
Also, in general soldering work, the operator may confirm the quality of the soldered part to a
certain extent by visually checking the appearance of the spread of the solder, the gloss of the
solder, the finish of the soldering, etc. Although it is possible, since the end 12a of the flat wire
tinsel wire is covered with the woven fabric as described above, it is difficult to confirm the
quality state after soldering, and the yield is deteriorated because the confirmation can not be
made. Therefore, it has been found that the quality and productivity in the wiring operation are
improved and the yield is improved by adding the improvement of the wiring portion which
needs to be soldered. Cone diaphragm 11 is broken along the copper foil 14 from the periphery
of the soldered part due to the difference in vibration mode between the copper foil 14 and the
cone diaphragm 11, and the copper foil 14 is cracked in about 400 hours and finally cut An
example was also found.
[0012]
The object of the present invention is to provide the above-described speaker wiring structure
previously proposed by the present invention, in particular, the end portion 14a of the copper
foil and the outer periphery of the dustproof damper 13 extending in the vicinity of the central
portion of the slope of the cone diaphragm 11 of the woofer 1 In the wiring structure and wiring
method for connecting the end portion 12a of the flat wire tinsel wire extending to the part, the
workability is improved, the quality is further improved, the production is more efficient, and the
yield is also improved. It is an object of the present invention to provide a speaker wiring
structure and a wiring method thereof.
[0013]
SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, in the present
invention, basically two types of wiring structures and wiring methods are adopted.
02-05-2019
5
The first wiring structure and the wiring method will be described with reference to the
drawings. A coaxial type in which the tweeter 3 as the high-tone speaker is disposed on or near
the central axis of the front surface of the diaphragm of the woofer 1 as the low frequency
speaker. A conductive material made of copper foil 14 or the like is attached to a diaphragm of a
low frequency speaker, and a dustproof damper 13 attached to the inside of the diaphragm is a
conductive wire made of a flat net-like tinsel wire 12 or the like. When connecting the end
portion 14a of the conductive material which is mounted near the slope center of the diaphragm
11 and the end 12a of the conductive material which extends to the outer peripheral portion of
the dustproof damper 13, the dustproof damper is mounted. A connecting member such as an
eyelet having conductivity is attached to the end 12a of the flat wire tinsel wire extending to the
outer peripheral portion of 13, and the end 14a of the copper foil of the cone diaphragm 11 and
the connecting member The dustproof damper In this case, at least a part or all of the soldered
portions, or all of the soldered portions according to the character of the cone diaphragm 11, are
connected to the connection portion at the end 12a of the flat wire tinsel wire of No.3. The
vicinity of the periphery was covered with an adhesive 18 or a coating material 16.
[0014]
In the second wiring structure and the wiring method thereof, the angle between the crosssectional shape of the bonding margin 13a provided on the outer periphery of the dustproof
damper 13 and the horizontal plane is set larger than the angle of the slope of the cone
diaphragm 11 The contact portion of the end 12a of the flat wire tinsel wire extending to the
bonding margin 13a and the contact portion of the copper foil 14 of the cone diaphragm 11 is
soldered, and at least a part, preferably all of the soldering portion is dustproof damper 13 And
the cone diaphragm 11 are covered with an adhesive 18 for bonding.
[0015]
[Operation] In the first wiring structure and wiring method, since the connection member by the
eyelet 15 or the like is mounted from the woven fabric surface of the dustproof damper 13 so as
to penetrate the flat mesh tinsel wire 12, the connection member is a dustproof damper The
contact member is in contact with the copper foil 14 of the cone diaphragm 11 disposed on the
outer peripheral portion of 13 and the connection member is in the form of a hole, so that the
surface of the copper foil 14 of the cone diaphragm 11 can be scratched from the front side of
the dustproof damper 13 When the front side of the connection member is heated with a solder
crucible and molten solder is poured into the hole of the connection member, the solder flows
from the hole to the copper foil 14 side, whereby the flat mesh tinsel wire 12 and the cone of the
dustproof damper 13 The surface of the copper foil 14 of the diaphragm 11 can be soldered
through the connecting member, and since it is substantially the same as soldering from the
woven cloth surface of the dustproof damper 13, soldering is extremely easy. Become .

[0016]
Further, in the second wiring structure and the wiring method, the angle between the crosssectional shape of the bonding margin 13a provided on the outer peripheral portion of the
dustproof damper 13 and the horizontal plane is set larger than the angle of the slope of the
cone diaphragm 11. Thus, an appropriate gap is opened from the contact portion of the end
portion 12a of the flat wire tinsel wire extending to the bonding margin portion 13a and the
copper foil 14 of the cone diaphragm 11 to the outer peripheral portion. The connection portion
of the copper foil 14 of the diaphragm 11 can be confirmed, and also in the soldering operation,
since the molten solder flows easily from the gap toward the contact portion, the soldering
becomes extremely easy.
Furthermore, since it is possible to visually confirm the soldered portion with both wiring
methods, it is easy to check the quality condition, and it is extremely effective for setting of
automatic solder such as setting of soldering conditions, etc. Productivity is improved, and by
covering at least a part or all of the soldered portion or the vicinity of the periphery with the
adhesive 18, etc., breakage of the diaphragm 11 around the soldered portion is prevented. And
the quality of the wiring is improved.
[0017]
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The preferred embodiments of the
speaker wiring structure and wiring method according to the present invention will be described
with reference to FIGS. 1 to 8. As explained based on FIG. 9 and FIG. The same reference
numerals are given to the same parts as those in FIG.
A pair of band-like copper foils 14 as a conductive material is pasted on substantially the center
line of the surface of the cone diaphragm 11 of the woofer 1 which is a bass speaker. Further,
according to the present invention, the wiring structure and wiring of the copper foil 14 mounted
on the inclined surface of the cone diaphragm 11 of the woofer 1 and the flat mesh tinsel cord
12 mounted on the dustproof damper 13 disposed inside the cone diaphragm 11 Since the
method relates to the method, the description of the other wiring parts, for example, the wiring
method of the cone diaphragm 11 and the voice coil 26 is omitted.

[0018]
In the first wiring structure and the wiring method, the dustproof damper 13 is formed by the
same method as the conventional dustproof damper 13. That is, after impregnating a woven
fabric or the like having a predetermined width with a phenol resin at a predetermined
concentration and volatilizing the solvent, the flat mesh tinsel wire 12 is sewn with a yarn 19 on
the center line of the woven fabric to obtain a predetermined heat. After pressing with a molding
die centering on the flat wire tinsel wire 12 and forming concentric corrugations etc. radially
connected from the center of the dustproof damper 13 toward the outer periphery, trimming is
carried out by an outline removing press Although a predetermined shape is obtained, in the case
of the present embodiment, a black woven fabric is used, and the yarn 19 for sewing the tinsel
cord 12 is also black.
[0019]
The flat wire tinsel wire 12 comprises a 200 denier para-aramid fiber as a central yarn, and a
0.32 mm wide, 0.027 mm thick tin alloy copper foil is wound around the central yarn at a rate of
22 turns / cm. Thirteen filament yarn lines were collected and braided in a flat net shape at a
braiding pitch of about 27.45 mm / time. In the case of the dustproof damper 13 of the present
embodiment, the flat wire tinsel wire 12 is mounted on the back surface side along the
corrugation, and the radiation method on the dustproof damper 13 is disposed similarly to the
cone diaphragm 11.
[0020]
In addition, a tongue-like convex portion 13b is provided on the dustproof damper 13 at the
outer peripheral portion where the flat wire tinsel wire 12 extends, that is, the outer peripheral
portion of the bonding margin 13a as shown in FIGS. The flat wire tinsel wire 12 extends to the
end of the tongue-like convex portion 13b. Furthermore, as shown in FIG. 1, an eyelet 15 as a
conductive connection member is crimped to the tongue-like convex portion 13b. The eyelet 15
penetrates the flat wire cocoon wire 12 from the surface side of the woven fabric, and the bent
portion of the eyelet 15, that is, the crimped portion bites into the flat wire cocoon wire 12,
thereby the eyelet 15 and the flat wire cocoon wire The wire 12 is conductive, and the diameter
of the hole of the eyelet 15 in the crimped state is about 1.6 mm.
02-05-2019

[0021]
The adhesive 18 is applied to a predetermined position of the slope of the cone diaphragm 11,
that is, the place where the adhesion margin of the dustproof damper 13 is disposed, and the
dustproof damper 13 is adhered. When the tongue-like convex portion 13b provided on the
outer peripheral portion of the bonding margin 13a and the copper foil 14 of the cone
diaphragm 11 are aligned with each other and correspond to the adhesive application portion,
the bonding margin 13a has a cone vibration. It is glued in place on the plate 11. In this state,
since the flat wire tinsel wire 12 is disposed on the back surface of the dustproof damper 13 as
described above, the crimped portion of the eyelet 15 attached to the tongue-like convex portion
13b and the flat portion extending to the tongue side A part of the wire mesh 12 is in contact
with the copper foil 14 of the cone diaphragm 11.
[0022]
Next, the hole portion of the eyelet 15 is soldered in a general manner. That is, when the front
side of the eyelet 15 is heated by a solder iron and the molten solder is poured into the hole of
the eyelet 15, the solder 28 flows from the hole of the eyelet 15 to the copper foil 14 side, and
the eyelet 15 and the cone diaphragm The solder 28 that contacts the copper foil 14 of 11 is
soldered, and the solder 28 that has flowed out to the outside of the crimped portion of the
eyelet 15 is the contact portion between the flat mesh tinsel wire 12 of the dustproof damper 13
and the copper foil 14 of the cone diaphragm 11. Are soldered, and the wiring of the flat wire
tinsel wire 12 of the dustproof damper 13 and the copper foil 14 of the cone diaphragm 11 is
completed. Furthermore, in the case of the present embodiment, as shown in FIG. 5, all of the
tongue-like convex portions 13b are covered with the black rubber adhesive 18.
[0023]
In the case of the present embodiment, the eyelet 15 is used as the connecting member attached
to the tongue-like convex portion 13b, but instead of the eyelet 15, the metal side having good
conductivity, for example, a thin copper plate etc. The same effect can be obtained by caulking
the projection 13b, and the shape and the like can be designed according to the purpose.
[0024]
In the second wiring structure and the wiring method, the basic structure of the dustproof
02-05-2019
9
damper 13 is the same as the first wiring structure and the wiring method, such as the
attachment method and shape of the flat wire tinsel wire 12, but the difference is the sticking
margin The tongue-like convex part 13b is not provided on the outer peripheral part of the part
13a, and the angle formed by the cross-sectional shape of the bonding margin 13a with the
horizontal surface is greater than the angle of the slope of the cone diaphragm 11 as shown in
FIG. The dustproof damper 13 set large was manufactured.
The dustproof damper 13 is mounted at a predetermined position on the slope of the cone
diaphragm 11 as described above. In the case of the present embodiment, first, the end 12a of
the flat wire tinsel wire extending to the bonding margin 13a is the cone diaphragm 11. It
arranges according to the position of the copper foil 14.
[0025]
As described above, since the angle between the cross-sectional shape of the bonding margin 13
a and the horizontal plane is set larger than the angle of the slope of the cone diaphragm 11,
when the dustproof damper 13 is disposed at a predetermined position of the cone diaphragm
11, As shown in FIG. 7, the inner periphery of the bonding margin 13a is in contact with the
slope of the cone diaphragm 11, and the outer periphery of the bonding margin 13a has a fixed
gap with the slope of the cone diaphragm 11 all around. Be In the case of the present
embodiment, the gap is set to about 2 mm at the outermost periphery of the bonding margin.
Therefore, the portion of the flat wire tinsel wire 12 extending to the bonding margin 13a
located on the inner peripheral portion of the bonding margin 13a contacts the copper foil 14 of
the cone diaphragm 11, and the outer periphery of the bonding margin 13a A clearance is
necessarily provided between the end 12a of the flat wire tinsel wire on the side and the end 14a
of the copper foil of the cone diaphragm 11.
[0026]
Since the end 12a of the flat wire tinsel wire extending to the bonding margin 13a can be visually
confirmed by forming a gap, it is easy to fit the end 12a to the copper foil 14 of the cone
diaphragm 11, and the gap Solder it. That is, a solder pot is disposed in the vicinity of the end
portion 14a of the copper foil of the cone diaphragm 11 by a general soldering method, and each
conductive material, that is, the end portion 12a of the copper wire 14 and the flat mesh tinsel
wire When the solder 28 melted in the solder pot is poured mainly on the surface of the copper
foil 14 of the cone diaphragm 11 while heating, the solder 28 flows to the inner peripheral side
02-05-2019
10
of the bonding margin 13a, and the inside of the bonding margin 13a Solder the flat mesh tinsel
wire 12 located on the periphery and the portion where the copper foil 14 of the cone
diaphragm 11 is in contact, and solder the flat mesh tinsel wire 12 of the dustproof damper 13
and the copper foil 14 of the cone diaphragm 11 Wiring with is complete. In the case of the
present embodiment, although solder balls and wire solder which are generally used are used for
soldering, it is needless to say that they can be soldered with cream solder and a heat beam or
the like.
[0027]
After wiring by soldering is completed, in the case of the present embodiment, a black rubber
adhesive 18 is provided in the gap provided on the entire periphery of the outer periphery of the
bonding margin of the dustproof damper 13 and on the inclined surface of the cone diaphragm
11. The dustproof damper 13 is mounted on the slope of the cone diaphragm 11 by applying and
adhering the bonding margin 13a and the cone diaphragm 11, but the adhesive 18 is applied to a
part or all of the wiring soldering portion It is covered.
[0028]
As in the above embodiment, by covering at least a part, preferably all, or the vicinity of the
soldering portion with the adhesive 18, etc., breakage of the diaphragm 11 around the soldering
portion is prevented. It is possible to improve the quality of the wiring.
Of course, there is a method to solve the problem by increasing the strength of the cone
diaphragm 11. However, since it is necessary to change the material and thickness of the entire
cone diaphragm 11, there are disadvantages in consideration of sound quality and
characteristics. However, by applying the adhesive 18 or the coating agent locally according to
the characteristics of the diaphragm 11 as in this embodiment, it is possible to more effectively
prevent breakage of the cone diaphragm 11.
[0029]
As another method, the angle with respect to the horizontal surface in the cross-sectional shape
of the bonding margin 13a provided on the outer peripheral portion of the dustproof damper 13
is set larger than the angle of the slope of the cone diaphragm 11, and further extends to the
bonding margin 13a. The end portion 12a of the conductive material and the contact portion 14a
of the conductive material of the cone diaphragm 11 are soldered, and a part, preferably the
whole, of the soldered portion is adhered to the dustproof damper 13 and the cone diaphragm
02-05-2019
11
11. The wiring structure covered with the adhesive 18 provides the following advantages.
[0030]
First, the angle with the horizontal surface in the cross-sectional shape of the bonding margin
13a provided on the outer peripheral portion of the dustproof damper 13 is set larger than the
angle formed with the horizontal surface of the slope of the cone diaphragm 11 as described in
the above embodiment. Thus, it is possible to provide a gap in the outer peripheral portion of the
bonding margin 13a.
Therefore, the end 12a of the flat wire tinsel wire extending to the bonding margin 13a of the
dustproof damper 13 comes into contact, and visual confirmation of the soldered portion of the
copper foil 14 of the cone diaphragm 11 and the flat wire tin wire 12 It is possible to easily
solder as compared with the prior art, and also to visually confirm the appearance of the
soldering as described above, and it is possible to improve the quality and the productivity.
[0031]
Further, since a part, preferably the whole, of the soldering portion is covered with the adhesive
18 for bonding the dustproof damper 13 and the cone diaphragm 11, the dustproof damper 13
and the cone diaphragm 11 are bonded. In the step of applying the adhesive 18, the portions to
be soldered can be covered simultaneously, and the number of manufacturing steps can be
reduced. In addition, this method can be easily realized by performing the adhesive application
step after the soldering step, which is the reverse of the general production method, and the
change in the production step also has almost the same effect on the production line. Not have
advantages.
[0032]
Further, when it is not desired to change the manufacturing process, etc., a tongue-like convex
portion 13b similar to the first wiring method is provided on the outer periphery of the bonding
margin 13a, and a horizontal surface in the sectional shape of the convex portion 13b. The angle
formed by the cone diaphragm 11 is set to be larger than the angle formed by the slope of the
cone diaphragm 11, and soldering is performed as shown in FIG. 7 to bond a part of the soldered
portion, preferably all or the periphery of the soldered portion It may be covered with the agent
18 or the coating material 16.

[0033]
Generally, in a car-mounted speaker or the like, the inside of the speaker grille is as unobtrusive
as possible.
For example, if the soldering portion or the eyelet 15 or the like placed in the grille is reflected
by the light from the outside and stands out, the driver cares about the portion and causes a
hindrance to the safety surface. There is a tendency to make Therefore, covering the eyelet 15
and the solder portion with the adhesive 18 or the coating material 16 has the advantage of
preventing reflection etc. in addition to the above-mentioned effects, and has the advantage of
meeting the demand on the design surface doing.
[0034]
Furthermore, conventionally, the yarn 19 for sewing the flat wire tinsel wire 12 of the dustproof
damper 13 is white, but when the sewing yarn 19 is also disposed in the grille, it is reflected by
the light from the outside and becomes noticeable. . Therefore, it is possible to easily suppress
reflection and the like by making the yarn 19 for sewing the flat wire tinsel wire 12 black as in
the present embodiment, and to have the advantage of being able to meet the request on the
costume side.

According to the wiring structure and the wiring method of the speaker of the present invention,
the dustproof damper disposed on the end portion of the conductive material extending in the
vicinity of the central portion of the slope of the cone diaphragm and the inside of the cone
diaphragm When connecting and wiring the end of the conductive material extending to the
outer peripheral portion, a connecting member having conductivity is attached to the end portion
of the conductive material extending to the outer peripheral portion of the dustproof damper,
and a cone via the connecting member Since the end of the conductive material of the diaphragm
and the end of the conductive material of the dustproof damper are connected and wired,
soldering can be performed from the surface side of the dustproof damper.

Therefore, since it is not soldering with the back side of the dustproof damper which basically
consists of woven fabrics etc. and the surface of the cone diaphragm as in the prior art, the
soldering work can be performed extremely easily.
For example, a worker who has general soldering knowledge can easily solder, and there is no
need to increase the proficiency level, and the spread of solder, gloss of solder, finish of solder,
etc. Since the appearance can be visually confirmed and the operator can confirm the quality of
general soldering points, the quality and productivity can be improved.
