DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement
of a speaker ve 1 -. In general, in the multi-way speaker system, the cause of the squawker
(speaker for speaker) who shunned to the enclosure of the woofer (speaker for the low echo
area) causes the back bite of the tweeter (speaker for the tone range) There is a jabbit in the socalled bank. This pack captain is a gimmick of Qu (to the point of progression), - rising of - (one
of the stiffness, a female female) that is configured as a small - Ding, the speaker's back 1. [It acts
to prevent and prevent a beta tatami by absorption of if wave, proper place, and backpressure of
Woofer. PAR) r 4 y '\ L "The back cavity in the conventional squawker is usually constructed as
shown in Figure 1, for example. In other words, look at the rear wheel of the speaker unit ll
during the rest of the illustration s * VC @ Back cover r 2 formed by inquiry into question. te, N'J
+ j ___ l 's speaker unit 11's 1 rglIIi 141' to form a backward cavity that will be used as the back
cavity BCI, for example 4 soak absorbing futs of glass wool notes I am making a droplet sacrifice.
However, in the conventional back cavity bc 1, it is understood that the back cover 12 forming
the ice nigra is composed of the molded product of 1 dumb - fat on the above - mentioned
droplet, and the dump truck tree by the cocoon - repellent material 13 Since there is no samurai
tL in the former name, we compared the front of the back cover 12 of the front cover 12 in the
prosperity near Sokka's / It is likely to occur. In particular, the crossover frequency with Woena
is set to / (lyl <C> Take a system by taking the system, the above crossover circumference + + 7
σ ___ at l cover 12. Generate abnormal sounds such as harmonic distortion due to the
coincidence of Hinoki. The resonance of this back cover 12 is caused by the abnormality of the
previous ml inviting the upper pit of distortion Du and Qo, etc., and it will cause harmful
influences on the auditory feeling as well as the shape, such as feeling of intermission. The book
', 4; clause prevents the ___ ___ shikaba bait that constitutes the back cavity with the older
brother who is accustomed to quantitative breaking with this body dispute V, to prevent QO and
distortion It is aimed at qk serving a great loudspeaker Table 4 who conducts a favorable +8
shochu with a low rate of fare. Explain one embodiment of the inconvenient plan with reference
to the circle. In the 2nd bad VC, 12 · Mapping the same billion speaker unit 110 'It is a back
cover which is drawn to the concave side, and this Cross'' sword bar 12 has the figure of C) After
returning to the enclosure, we are going to return the enclosure to form a sheet-shaped
viscoelastic wooden piece made of rope 4, consisting of large crimps Yuya Temple with a ratio n
to the boat, 14 and vA 7f.
In the pack captain BC 2 composed of the back cover 12 with the beneficial "□ -1 frost 5, -"
supplemented by this giant franking material 14, 4 × of the same body kneading material Jj is
filled conventionally. このmamxとすれば、バックキャビティHC2を! Since I H [MI force, t sx n, @ nas feather I 4 or - I ≦ is written, at the back of the speaker unit ll - ", if it is in the back
cavity BCi 2 by the iWK Tsuji If or soup @ 13 It is absorbed by the era, and it is absorbed in the
effect FI 9 by the imagination temple of the interlinking member 1 - 1, which is absorbed by the
era, and the 7 gouge force due to the lit pressure to the luggage cover 12 is weakened . In
addition, as the Okami elasticity · member 14, it is hard to imitate the cocoon liner cover 12
eyeglasses due to its 1ict and viscous loss due to its big snout, which is a big snake in hunting.
Therefore, the above-mentioned precaution of the back cover 12 is effectively prevented, the
occurrence of the above-mentioned co-generation is prevented, and Q and the rise are also
coming up. 1. Well, these 4 juice, elasticity member! 4 as i 5 + 5 shield note y im yarn Asphalt
is in HA, so it is possible to crimp it with a simple chestnut to ↓ against the W lany cover 12.
Incidentally, an example of the actual # result concerning the case where the present invention is
not actually applied is shown in Fig. 8 -), (b), (c), (the phrase. 8 (a) - 8 (d) show a case where a
bank cavity is formed by a back (2) cover 12 made of conventional leave-made knicking molded
product using a 16 LM cone type squawker and a sound absorbing material 13 And the back
cavity (back side) of the southern im-thread asphalt of the thickness as several kinds of southern
elastic members 14 as the elastic member 14 over the entire interior of the internal journal of
the self +18 crotch cover 12 And identified the six characteristics in the anastomosis (indicated
by the solid line) in which sound absorbing material 13 is filled substantially in the same spirit as
the Akira inside. Irubu - Tatsumi ") ijltd" "" "1 '" 11 "□, i" taen god Note, (e)? 2nd Hisashi

Furthermore, in the second and eighth harmonically shadowed umbrella → 1 + in Figs (a) and (d),

with the testimonial of the testimonial, it is possible to regret by using the award, but it can be a
bigger effect thanks to the fact that the personality is high and the genius is great. In addition, at
the above-mentioned center about, the celebrating friends who celebrated 1 sweet using
synthesized tree prepared items as the back cover 12, and the anastomosis conducted on the
covered cover of Bessharu Shimmusha was almost one day j cool It is effective. So, ') Other, this
