FIELD OF THE INVENTION This invention relates to coaxial speakers. 2. Description of the
Related Art In recent years, coaxial speakers have come to attract attention because of their
excellent sound image localization. The conventional coaxial speaker will be described below. Fig.
1 is a block diagram of a conventional coaxial speaker, 1 is a tweeter equalizer, 2 is a tweeter
frame, 3 is a tweeter diaphragm, 4 is a tweeter plate, 6 is a tweeter magnet, and 6 is a tweeter Of
the yoke, 7I'J, a spacer between the tweeter field part and one to the ha field part, 8t woofer jIJ
(action 1k, 9aI; I, + 7-ha inner edge, 9b the woofer outer edge, 10 is a plate of woofer, 11 is a
magnifier of woofer, 12 is a frame of 3 I-even of woofer, 13 Q or a frame of woofer, and 14 is a
baffle plate. Here, the inner edge 9a of the woofer is tJ! Between the equalizer 1 of the tweeter
and the flat 20 of the tweeter 1) and is jl 11-. The operation of the coaxial speaker configured as
described above will be described below. By arranging the tweeter and n-ha in the same -tlQl, J :,
this nubica can stabilize the localization of the sound and produce an ideal sound source.
However, in the two conventional 1116 configurations, the inner edge 9a of the woofer is fixed
between the tweeter equalizer 1 and the tweeter frame 2 so that the tweeter is placed on the
woofer plate ?2?. The problem was that the woofer could not be completed without the habit
and the tweeter and woofer could not be magnetized in the opposite direction. Also, if only one
range (woofer or tweeter) breaks down, Nubika Unitz of that range! -There was also a problem
that it was impossible to take only 1 '. SUMMARY OF THE INVENTION The present invention
solves the above-mentioned problems of the prior art, and is a coaxial type that can be attached
and removed while combining the speaker unit 711D vibration system of each range for high
and low tones and the corresponding field unit. The purpose is to provide nupeca. Configurations
of the Invention The present invention is a diaphragm, an edge, and a frame, respectively. A
speaker unit for high and low tones in which a field unit is integrally assembled, and a spacer
fixed to the field unit of the speaker unit for low tones; and fixing the high-sound speaker unit on

the spacer The edge of the low frequency speaker unit is fixed by ?1 to a part of the spacer, and
the edge of the low frequency speaker is fixed not to the parts of the high sound speaker unit but
to the negative portion of the spacer 771 ? ?. Each speaker unit can be attached to and
detached from the 1 f G dynamic system and the field unit in combination.
Description of the embodiment FIG. 2 shows the construction of the same 11Ql + -type nubica in
one embodiment of the present invention. In FIG. 2, 1 is a tweeter equalizer, 2 is a tweeter frame,
3 is a tweeter diaphragm, 4 is a tweeter plate, 5 is a tweeter macnet, 6 is a tweeter yoke, 8 is a Uha vibration. 9a is the inner edge of the woofer, 9b is the outer edge of the woofer, 10 is the
woofer plate 12 is the woofer yoke, 13 is the woofer frame, and 14 is the panfull plate, which are
the same as in the conventional example. . Reference numeral 16 is a screw for fixing the
tweeter, and 16 is a frame for fixing the inner edge 9a of the woofer, and the spacer for
separating the field part of the tweeter and the field part of the woofer is also used as the frame
for fixing the edge. . As described above, according to the present embodiment, the spacer
between the field portion of the tweeter and the field portion of the woofer has a role of a frame
for fixing the inner edge of the uno 1 and the tweeter is screwed in this frame Because it is fixed,
the tweeter and the woofer can be separated as they are completed. This makes it possible to
increase the magnetic flux density of the gap as shown in Table 1 in which reverse magnetization
of the tweeter and the woofer is possible. However, the condition is that the woofer magnet is
?90 О ?18 О t1 1. The tweeter magnet is ?60 О ?26Xt. 9 In addition, tweeter or woofer
single item exchange is possible. TABLE 1 Effect of the Invention on Measured Data of Magnetic
Flux Density The present invention relates to a diaphragm, an edge, and a frame, respectively. A
speaker unit in which a field unit is integrally assembled and a spacer fixed to one field unit of
the low j ? ? bladder 11 speaker unit; The speaker unit of the speaker unit is fixed, and the
edge of the above-mentioned speaker unit for bass is fixed to a part of the nubeza. The edge of
the speaker for bass is fixed to a part of the spacer instead of the parts of the speaker unit for
treble By doing this, it is possible to attach and detach the vibration system and the field section
of each Sveker unit 1-as far as possible. For this reason, it is possible to significantly improve the
zerbine property. Furthermore, by enabling the attachment and detachment of each speaker unit
alone, the field parts of each speaker unit are magnetized in the opposite direction to each other,
and the magnetic flux density is extremely high. It is possible to realize an excellent coaxial
speaker that can also obtain the effect of being able to
