BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a top view of a composite speaker with a part

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a composite
speaker which is an improvement on tinsel wire. メー/どA、27)−J’。 Conventionally,
for the connection of the tinsel wire in the composite speaker, a method of drawing out two tinsel
wires from the terminal to the bass speaker and the middle sound speaker, and an eyelet being
struck on the diaphragm of the bass speaker to pass the tinsel wire There is a method of
soldering and connecting the tip of the tinsel wire to a speaker for medium sound. However, in
the former case, the cost is increased due to the need for two twine wires, and the cost increase
of the twine wire processing man-hours is also extremely disadvantageous, and the blind person
has a place where the twine wires pass through the diaphragm. Because it is one place, it is
difficult to realize the lead-out position respectively suitable for both the bass speaker and the
mid-tone speaker, and since the tinsel wire is perpendicular to the diaphragm, the eyelet and the
tinsel wire Soldering of the lead wires of the eyelet and voice coil is difficult), and the solder may
flow into the tinsel wire during soldering of the eyelet wire and the weir wire in the tatami mat,
which may cause disconnection. The present invention has been made in view of the four points
as described above, so that three holes are made in the diaphragm of the bass speaker, and one
tinsel cord is drawn to reach the mid and / or treble speaker. Further, the voice coil lead wire of
the bass speaker is connected to the part where the tinsel wire is stuck, and the above-mentioned
problems are solved. Hereinafter, one embodiment of the present invention will be described
with reference to the drawings. Reference numeral 1 denotes a first magnetic circuit comprising
a magnet 1 yoke, yoke lb, and gray 10, and a central portion of a company bass diaphragm 3 is
fixed to a bobbin 2 whose voice coil 21 portion is located in the magnetic gap. Then, the first
damper 5 is attached between the fixed portion and the first frame 4 (-, and the edge 7 is
interposed between the outer peripheral end of the bass diaphragm 3 and the second frame 6. It
is attached. A spacer 8 is attached to the center ball of the yoke 1b of the first magnetic circuit 1
with a screw 9), and a second magnetic path 11 is attached to the tip of the spacer 8 by a screw
10. The third magnetic circuits 12 are respectively attached by agents. And between the outer
periphery of this spacer 8 and the said low frequency diaphragm 3, the 2nd damper 13 inclined
so that a center direction might become high is attached. The second magnetic circuit 11 is a
magi) 111L. The center portion of the diaphragm 15 for medium sound is attached to the Pobien
14 which is constituted by the yoke 11 b and the plate 110 and the voice coil is positioned in the
magnetic gap, and the diaphragm 1S for the medium sound is It is attached to the third frame 1
@ via the outer peripheral edge.
The voice coil of the high-tone diaphragm 1T having a dome shape is located in the magnetic gap
of the third magnetic circuit 12 ', the magnet 121L and the yoke 12). 18 is an edge damper, 19 is
an equalizer, 20 is a horn, and 21 is a fourth frame. A cap 22 is fitted to the outer peripheral
portion of the second frame 6, and a plurality of stays 22 & are formed in the middle yam 22
therein. Further, a dustproof cloth 23 is stretched on the cap 22 so as to cover the low frequency
diaphragm 3 when it is fixed to the second frame 6, and a protective net 24 is attached thereto. A
name plate 25 is attached to the center of the protective net 24. The tinsel wire 26 of one pole is
drawn out from the terminal 2T of the first frame 4 and is a position suitable for the lead wire of
the voice coil shown on the diaphragm 3 for bass, a position suitable for a speaker for middle
sound, the middle The three holes in the position are passed to the intermediate terminal 28, and
from there, they are connected to the voice coil lead wire of the medium sound diaphragm 15
and the voice coil lead wire of the high sound diaphragm 1T. The lead wire 21L of the voice coil
2IL of the low frequency diaphragm 3 is fixed by an adhesive over the surface of the diaphragm
3 and fixed by soldering to a part 26 of the tinsel wire 26 ing. The above is true for the W pole of
the other pole. In the above, at the time of assembly, first, the bass speaker including the first
magnetic circuit 1 and the bass diaphragm 3 is assembled, and separately from the spacer 8, the
second magnetic circuit 11 and the middle sound diaphragm 15 are included. A mid-tone
speaker and a high-tone speaker including the third magnetic circuit 12 and the high-tone
diaphragm 17 are attached in advance. Then, the spacer 8 is fixed to the top of the center ball of
the yoke 1 b of the first magnetic circuit 1 by a back screw 9. The tinsel wire 26 from the
terminal 27 is wetted in the holes of the diaphragm 303 during the bass speaker assembly, and
the lead m2 turtle is soldered to the portion 26 turtle. The connection to the intermediate
terminal 2a is made after the assembly of the spacer 8. The first grombar 13 is attached after the
assembly of the spacer 8, although it is attached at the time of the assembly of the speaker for
the first damper. The second damper 13 not only functions as a damper, but also performs a
dustproof function on the magnetic gap of the bass speaker. The cap 22 is fitted last. Note that in
FIG. 1I43, the tinsel wire 26 'is wetted in the radial direction of the bass diaphragm 3. As
described above, according to the present invention, the diaphragm of the low frequency speaker
is provided with a position suitable for the lead wire of the voice coil of the speaker, a position
suitable for the medium sound and / or high sound speaker, and a hole in the middle position. In
addition, the tinsel wire from the insulator is dipped in these three holes to reach the medium
and / or high tone speaker, and the tin system between the holes in the middle hole and the holes
suitable for the lead wires' 2. The lead wire is connected to the wire.
For this reason, since it is not necessary to use an eyelet, the number of assembling steps is
reduced, and the occurrence of rusting due to the paste used for eyelet solder is also eliminated,
and there is also no possibility of disconnection due to solder flow. Further, the tinsel wire can be
drawn out at the position most suitable for each of the bass speaker and the mid-tone speaker so
that the reliability can be improved.
