[Detailed description of the invention] The present invention is used for car stereos and used for
b car's ski cabs and car b's, and it's a good thing to try to provide excellent bass without using
car's trunk etc. It is. In general, for the car Sukikabo, as a coffin, 枦 1! As shown in Fig. IE2aK, the
speaker 2 is attached to the inside of the small box main body 1 as shown in FIG. 撫:, y,-. ・ Ε: ・
・ ・ 2 [、 、 ボ タ ス タ ス タ ス タ ス タ ス タ ス タ ス タ ス タ ス Because of the ring and one,
it is a great deal to get the bass Ktk ゐ. As described above, conventionally, as shown in FIG. @,
The through hole 4 is formed in the rear tray 3 to obtain the bass by utilizing the y product in
the trunk. Coming up, it is a large one to put things in, and the volume is refined by putting in
and out of things, and it's difficult to save money. When closing the huge trunk, large pressure is
applied from the through hole 4 to the inside of the main body 1, which may damage the
diaphragm of the speaker 2. As described above, the present invention 1 is a turtle that
eliminates the disadvantages of the prior art. I! s is a synthetic 1 fat, such as k, and a Tas body,
a sound emission hole 6 is formed on the BO @ surface of the box, of which 1111 K Hanubica
Ding is a joint 19; The bottom of the speaker T, that is, the lower surface of the field weir, KFJ,
has been mounted. Jet, l, Tas body 60 lower end? ◆ A small distance t, a through hole-shaped
free tray 10 is placed in the center, and this body 8 # 'i rear tray 11 is worn on the rear tray 11.
Thus, a duct 12 is formed on the rear tray 11 and the J1210, and the duct 9 is paired with the

duct 9 and the lower part of the body δ * "* 11w'i air hole -11 m, 14 ing. With such a
configuration, the low tone is emphasized by the action as a pack loan indication of the duct 12
by the 1 Wi storage compartment 8 middle 10 and 1 end tray 11 r coming out of the front
movement of the speaker 7 It's in the shape of a heart. That is, according to this configuration, in
comparison with the sound pressure-frequency characteristics shown by 阜 jliM sbi capo and 砿
曽 in the configuration shown in FIG. I am holding it. As described above, the speaker car for this
car +111, the cousin is made up for 82721% +1 擾 <Even if the bass sounds and the processing
of the rear tray is not necessary either, and 2 h) and the trunk The vibration of the speaker is
open and closed, and the vibration of the speaker is not good. It is a big b of practical value, with
the improvement in the characteristic and the improvement in the quality.
