[Detailed description of the invention] The present invention relates, for example, to the
improvement of a composite type speaker in which a horn and a tweeter are coaxially
incorporated in a woofer. ? \ Heretofore, there have been, for example, those shown in FIG. 11
as a composite type scissor in which a horn tweeter is combined with a woofer, for example. That
is, the woofer part is formed by incorporating the horn and the one part B, and the woofer earth
is formed by fixing the voice coil 2 fixed on the lower surface of the cone-shaped diaphragm 1 to
the magnetic gap 3 & And is fixed to the upper surface of the diaphragm 1 magnetic circuit 3
and is fixed to the outer peripheral step 11141 L of fc7 frame 4 via the edge 5 as a backing 6tpress 1 and further joining the diaphragm 1 and the voice coil bobbin 2 The portion is fixed to
the frame 4 using the damper material 7t. On the other hand, the horn tweeter part B is fitted on
the upper surface of the magnetic coil 1 of the woofer part by means of a screw 8t-using a screw
ms t of the mounting member 8 screwed in place. A voice coil bobbin 13 having a dome-shaped
diaphragm 13 and a tube and supported by a support member 12 by a damper 11 is inserted
into the gap 10 of the magnetic circuit 10, and an equalizer 141L disposed above the vibration &
131L. The horn 14 is fixed to the support member 12 using several screws 15t, and the grill 16
separately formed from the horn 14 is fixed to the flange 4b of the frame 4 from the upper
surface of the backing 6 The upper surface of the woofer section is formed backward by the grill
16. By the way, there is a demand that the size of the garden must be as large as the horn 14 of
the horn / tweeter part B in order to improve the efficiency and directivity characteristic of the
01-05-2019

conventional composite type speaker. It projected from the front to the top of the woofer section.
And at the time of production in the line and management of semi-finished products, the
assembly work was performed by placing the horn 14 of the horn tweeter part B on the line with
the bottom face on the bottom, and the product was stricked in a certain place ^ Since the horn
14 of the horn and tweeter part B protrudes from the front face of the woofer part as described
above, it may be stored when it is inverted and placed at a 2-in top or a certain storage center.
Since it is easy to fall down and stability is deteriorated, the assembling operation efficiency is
deteriorated, and it has been difficult to store it again. In addition, the horn 14 is formed
separately from the grille 16 that handles the upper surface of the woofer part, and this horn 14
protrudes from the horn fist weeter & b so that it is unnatural and unmatched with the whole. It
becomes a shape.
The present invention was made in view of the above-mentioned point, and the place made into a
purpose is the horn of the horn tweeter part by making the upper surface of the Patzkin which
holds the steel plate of Uno Nm to the outer step of the frame as a reference plane. The driver /
unit lW and the grille side can be assembled by being divided into two parts, so it is flat and
stable when it is inverted and placed on a line etc. during assembly / production or storage of
semi-finished products. When the working efficiency is the same, the present invention is to
provide a composite speaker suitable for collusion and storage. The details of the present
invention will be described below according to an embodiment shown in FIG. In this embodiment,
the upper surface of the pad plate 6 which holds the vibration & 1 of woo-ha-tsumu to the
outside 1aMjt% aa of the frame 4 is used as the reference plane X to set the horn 14 of the horn
tweeter 1ilB to the first horn of the driver unit b @ It is formed of a stripe 2 horn component 14
B which can be assembled on the upper surface of the child 14 and is integrally formed with the
grill 16. Then, the same fixing means as in the prior art, for example, 7 ramps 4 b K ffi of the
frame 4 of the d woofer section are attached to the outer edge portion 161 L of the grill 16 * I / I
bFi by means such as screwing. Then, for example, an adhesive is used to bond the second horn
insulator 14B to the first horn sb child 14m. The reference numeral 17 denotes a mesh which
holds its outer peripheral edge 17k in the curvature of the first horn component 14m and the
second horn component 14B, and the reference numeral 18 denotes a meso 7 which is stretched
in the hole 19 of the grill 16. The other structure is the same as that of the conventional complex
speaker in FIG. 1 and the description thereof will be omitted. Note that the same parts in the
drawings are denoted by the same reference numerals. One embodiment of the present invention
is configured as described above, and the horn 1.4 of the tequator speaker unit B is the first horn
component 14 of the driver unit b- and the second horn component of the grille @ 16. The upper
surface of the pad 6 for pressing the outer peripheral portion of the diaphragm 1 of the woofer
part to the outer peripheral step 4a of the frame 4 can be assembled separately as a reference li]
x. Therefore, the second horn structural member 14B integrally formed with the grille 16 is
erected at the time of assembly, assembly or storage of a semifinished product, which is inverted
on the production line or storage area of storage space, ie, when the horn is placed down. (1) If it

is separated from the horn component 14m, the horn 14 is pressed against the upper surface of
the patch 6 which presses the outer peripheral part of the diaphragm 1 of the horn to the outer
peripheral step 41 of the frame 4 through the edge 5 as before. Can be placed stably because it is
not loaded from the front of the woofer section.
The second horn component 14B is attached to the first horn component 14 by bonding or the
like using an adhesive, and the outer edge portion 161 ft adhesive of the grill 16 integrally
formed on the second horn component 14B is used. And fit the outer peripheral edge 171L of
the frame 17 between the first horn structural element 14 and the second horn component 14B,
and assemble the product as a product. . Also, since the brown 2 horn component 148 is
integrally formed with the guri 16, the horn 14 of the horn / tweeter part B or the front face of
the woofer is similar to the conventional combined type sceaker shown at the first cause. There is
no need to be an unnatural shape, as it does not look like being torn apart, and it does not break
down the whole as a whole. As described above, according to the present invention, the horn of
the horn tweeter portion of the driver unit ta of the driver unit ta of the woofer portion of the
woofer portion is held on the outer step of the frame with the ifl as the reference surface! @ 1
Horn component and 2nd horn component on the grille side can be assembled in two parts so
that assembly is possible in line-it is inverted and placed in line when storing semi-finished
products in storage However, if the second horn component is separated from the first horn a
child, the upper shoulder of the outer shoulder of the diaphragm of the woofer will be flat with
the upper surface of the patch as the reference surface. It can be stably placed. Therefore, the
assembly operation efficiency is improved and suitable for stacking and storing. 4. Brief
