DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pedestal-type
loudspeaker (--a combination of a low-profile loudspeaker and a loudspeaker for acupuncture).
Fig. 1 A conventional scallop made by combining a low sound speaker A + and a treble mountain
with a sconce, not shown, (figure 2) A first bottom plate (3) having a center-two-center ball (21),
and a first annular magnet (41, the first bottom plate (31) mounted on the first bottom plate (31);
The first top plate 161 is mounted on the second magnet 141 and has a 14th air gap + 5: vtlbMT

composite type speaker, a space where the high-tone speaker mountain is coaxially positioned
with the low-pitch speaker ˜ and the space surrounded by the cone-type diaphragm 1] [1 Since it
is housed in two, it is advantageous not only in terms of space utilization, but it also has the
advantage of obtaining high-quality 4 reproduced sound with stable phase characteristics, but it
does not prevent the progress of sound waves from the bass speaker A The present invention,
which has a drawback that the size of the second magnetic circuit is limited and the output from
the high-pitched speaker a is insufficient for the purpose of the present invention, is for the
purpose of falsifying the above-mentioned flaw. A part of the string east obtained from the
magnet of the air speaker circuit of the low frequency speaker is a magnetic gear tube section
formed with the air speaker circuit of the high frequency speaker-guided to the inside of the air
air gap It is the same as the one east density.
FIG. 2 is a top view of the composite speaker of the present invention according to the four-port
type of the present invention, and FIG. 1 is a longitudinal sectional view of the same. In these
figures, the same reference numerals as in FIG. 1 indicate the composite speaker of FIG. 1 and
the one 1--, and ▪ indicates the first center ball (2: and the second center pole 0). A magnetic
pole made of a magnetically coupled magnetic material, and this connection is made by coupling
C1 between an external thread formed on both ends of the magnetic ball and an internal thread
formed on both center balls 121t13 +- There is. A magnetic frame 5 is a magnetic frame made of
a magnetic material, and the bottom surface of the first top plate 161-2 is uniquely bonded. C!

The 14 ha auxiliary magnetic path-1 supplies a magnetic circuit O2 of the hydrogen 2 and a
straight line 2i air cap 0 泪 − to supply a magnetic flux, and the second voice coil U is operated
to perform dome oscillation (2) − It will give you enough power. On the other hand, since the
magnetic flux from the first annular magnet (4: is also led to the first magnetic gap U via the first
magnetic gap (5 (other than (-the above-described auxiliary magnetization) path) The reduction
of the magnetic flux in the air gap 15) is easily eliminated by increasing the first lumped magnet
14) to increase the total loss 7 ◆ ≦ 2 depending on, the size of the first magnetic circuit Il + is
increased ◆ Our damage is 11 degrees that can be done without attack. According to the present
invention, the speaker of the present invention is a magnetic speaker for fixing the center ball of
the center pole of the first magnetic circuit and the second magnetic circuit of the first magnetic
circuit. With the hall. A yoke 1'-coupled magnetic frame of the first magnetic circuit and an
interlocking releasable reciprocation member 111 made of a magnetic material for connecting
the open sides of the top plate of the second magnetic circuit; As it is provided, a part of the
magnetic flux obtained in the first magnetic circuit is generated in the magnetic gap of the
second magnetic circuit (a second lead may be produced. Therefore, the magnetic flux obtained
in the second magnetic circuit is insufficient. [Phi] can be applied to the magnetic gap of the
second magnetic circuit, so that the output from the high-pitched speaker can be increased.
Further, in the pedestal type speaker according to the present invention, the connecting member
is formed radially from the top plate of the second magnetic path (the twenty-eighth bridge
portion comprising two or several magnetic materials, and the frame The first bridge, which is
made of J2 Sumoto's vulcanizable material, is connected with the first bridge city from the
opening side of the main part, so there is no ◆ leads the magnetic flux of the magnetic circuit to
the magnetic cap of the magnetic circuit of H2 and becomes μ function, and light low @ sound is
obtained. In addition, as the ream 4a house material of the present invention, it is possible to use
a thing capable of engaging / disengaging qt 1 if the present invention combined type speaker is
of this series fIs material) thread de-separating [4h in-speaker and bass speaker The output ratio
between the two can be made variable, and it is possible to divide the stool into one (1) or two
(6), which is a combination of high-pitched speaker or low-contrast speaker. In this embodiment,
the first magnetic circuit (11 of the external magnetic type is used as the first magnetic circuit
(11), but the center ball is placed on the magnet [11 [11 The inner yoke type magnetic circuit in
which a magnetic gap is formed by the compensated yoke on the lower surface, the center ball,
and the C1 is also ugly.
