effective mass of the air Og in the boat and the medium Yabinette gate lIO air = = consistent and
wave number determined by the compliance and k, and the lowest resonance shoulder number of
the speaker itself Its length is determined to be-3 to be consistent with. The nine-pass reflex
cabinet configured in this way is the speaker itself O lowest resonance frequency O above and
below (thereby making a resonance range for DR wave number part), the reproduction

O is expanded to below the frequency, the reproduced sound in the bass region obtained from
the one-pass reflex cabinet is generally a broken OM--for example, a drum, so it can be used as a
drum. I was not satisfied with the reproduction of the low-end O-biso sound. In order to improve
the 110 points, conventionally, for example, squeeze glass cool or cotton cloth in the round part
of the boat to reduce the value of the sharpness q of the resonance K), Even in the conventional
method, the buying of the in-boat lIO air which determines the low-frequency am frequency
together with the compliance exhibited by the air inside the cabinet F is substantially zero in this
conventional method. There is a drawback that a resonance peak does not appear. According to
the present invention, when a maze-like passage is formed between the openings at both ends, a

the mass band shown in O 5 Iill (2) 5 I is the bow) PK The resistance is OK, as shown in the
figure, but it is OK as opposed to the figure in the figure. In the figure, the figure shows O% OK or
not. The acoustic resistance that is generated when forcibly passing 9 air into the pipe O is
expressed by the fact that large acoustic resistance occurs in the poda at the time of the radiation
of the amount of impact of the cocoon, and the sound resistance is adjacent to the nine air layers.
O If the sound wave normally propagates in a large diameter tube, but the viscosity is considered
to be friction between O, then the tube O axis K [all O in an angular plane? ! In the case of
pigeons where the sound particle propagates the sound waves into small diameter tubes, the air
O particle device is zero in the tube ambiguity, as the air particles carry out the same movement
and thus the losses (resistance) generated by the abrasives are small. And 61. Depending on the
position of the pipe O in the radial direction of the pipe, the amount will be large at the center of
the pipe. Influence on the air O flow Os Os length is large heat (It becomes% O where resistance
becomes large II, t, and the above-mentioned acoustic resistance Okichi S which is generated as
above, air O flow is electric Even when it changes continuously into the world, it will be greater
than if it flows continuously. Therefore, as shown in 1 ml and 1 o, both ends O! IIIqsl & IIK A
configuration in which a few partitions are alternately projected from opposing murals so that a
maze-like passage is formed O) PK or i is provided with a partition and the air is compared to a
single boat Since the diameter of the flow passage O is made small, nine sound resistance cities
are generated accordingly, and at the time of the impact sound O section, the sound resistance
assistance which appears in the steady state according to the particle velocity to rapid change of
the air flow ! Even the big acoustics! ? It is because assistance (but K) l) occurs. The above
mentioned port PK echoing resistance assistance! -A large heat of assistance can be set as in

provision of the required acoustic resistance, the fence partition plate is provided in the Pow 42
yen, and the pass / pass 7 rettuss / mid-yavinets are required for the boat to perform the O
operation originally. One yen! In the present invention, according to the present invention,
according to the present invention, the conventional example 0% GIC does not have one
drawback, and the bus ret It is possible to get a volume AK by Yabinette.
The Fang 4 garden gives the speaker an input corresponding to the bass O O-sound as shown in
the 4 4 (a) illustration and shows the waveform of the reproduced sound generated at 9 o'clock,
