DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the structure of a
speaker in which a tweeter is incorporated in the center of a woofer. A coaxial speaker in which a
tweeter is incorporated in the center of a woofer having a ring-shaped diaphragm has
conventionally been known to have a structure as shown in FIG. 1 (1) // ((2 1 1)). ing. In the
figure, when (1) is a yoke, (2) is a magnet, and f31 is a plate to adhere and bond these three
components, a magnetic circuit of a part of the woofer is formed, and a woofer frame (4) is fixed
to this. There is. Then, the diaphragm (51, spider (6), voice coil (7) is fixed by adhesion to this,
and a part of the woofer is completed. (8) is an outer edge for supporting the diaphragm, and (9)
is an inner edge. The weir is an inner frame which also serves as a mount for fixing the inner
edge (9) and for fixing a part of the tweeter to a part of the woofer, and is fixed on the plate (3)
by a screw. On the other hand, a part of the tweeter is a pole piece of a cocoon, a magnet of a21
and a plate of u to form a magnetic circuit like a part of a woofer, to which a tweeter frame value
is fixed by a screw. And with this, the diaphragm a5. The vibrating yarn of the voice coil α e%
spider (2) and the dust cap as is fixed by an adhesive, and a part of the tweeter is completed. A
part of the tweeter is fixed to the inner frame 0 by a mounting screw α 曽. (2)、−! As
described above, in the conventional coaxial speaker, the structure is complicated and the

assembling operation is very complicated. Further, as a problem in design, there is a defect that
the mounting screw 09 can be seen from the outside, and a gap (joint) between the inner frame a
+ 1 and the tweeter frame a− is formed, and the appearance is unsightly. In this regard, in the
recent audio market, the weight of the design element in the commercial value tends to increase,
and the aesthetic appeal of the speaker is strongly demanded. The present invention has been
made to eliminate the disadvantages of the prior art as described above, in which the tweeter
portion is directly fixed to the top plate constituting the magnetic circuit of the woofer portion,
and the ring of the woofer portion By fixing the inner edge provided on the inner periphery of
the diaphragm to the tweeter frame, it is possible to provide a cheap and beautiful speaker with
high commercial value. One embodiment of the present invention is shown in FIG. 2. In FIG. 2,
the mounting screw or adhesive on the plate (3) constituting the magnetic circuit of the woofer
(3) part by the 1141 # 'i tweeter frame. It is fixed by.
The magnetic circuit of a part of the tweeter which is composed of the pole piece αυ, the
magnet tap, and the plate a3 is fixed to the tweeter frame I. Then, the vibrating threads of the
diaphragm aS, the voice coil ae1 spider surface, and the dust cap am are fixed thereto by an
adhesive and assembled, and a tweeter is completed. A part of the woofer has an inner edge (9)
attached to the inner periphery of the ring-shaped diaphragm (5) and an outer edge (8) attached
to the outer periphery with an adhesive, and an inner edge (9) The other end is fixed to the outer
peripheral portion of the tweeter frame 14 by an adhesive or a ring-shaped holding plate.
Similarly, the other end of the outer edge (8) is fixed to the woofer frame (4). Thus, according to
the present invention, the inner frame Q, which is conventionally required, becomes unnecessary,
and the attachment screw a also becomes unnecessary. Therefore, the number of parts
constituting the speaker is small and the structure is simplified, which is economically
advantageous. In addition, (4) the design problem which has been a problem in the prior art, that
is, the case in which the attachment screw α 嘗 is eliminated and the boundary (the connecting
“eye”) between the inner frame and the tweeter frame No. Because it looks beautiful and
beautiful, its commercial value is extremely high. In the above embodiment, the magnetic circuit
of a part of the tweeter is fixed to the tweeter frame I at the bottom of the pole piece αυ, but it
is fixed to tweeter frame No. 0 at the top of the plate 0 as shown in FIG. . The bottom of the pole
piece αυ may be fixed directly to the top of the plate (3). In the L embodiment, the case where
the tweeter is a cone-shaped speaker has been described, but a flat plate, a dome, a horn or the
like can be similarly applied, and the same effect can be obtained. As described above, according
to the present invention, it is possible to provide a coaxial speaker which is beautiful and has a
high commercial value in view of the appearance only at low cost.
