DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the improvement
of a speaker provided with a filter plate having a large number of through-holes in the 111111i
of the diaphragm and allowing the control of the air space braking effect of the filter plate. ?
thousand-to try to provide a mourning thing to enable an adjustment of frequency frequency is
also D. In the past, it has been clarified that a filter board is used to improve the maximum II &
quantitative frequency m and the high limit w4 wave number. An example is shown in FIG. 1 is a
field on the center pole 2-a field that is wg-ed by a ring plate, magnet plate 24 and a ring plate J]
upper plate 6 и Is combined, this frame 6! D Attach the diaphragm T and caskerato 8 to the
peripheral edge, and further attach the conical filter plate 10 with many through holes 9 formed
on the gasket 8, and place the damper 11 in the middle of the diaphragm a The voice coil 12 in
which the product is held is V-matched, and a dust cap 18 is attached to the center of the
diaphragm 70 upward. By this construction 7, when the umbrella plate a, am plate 7 is operated
to the presence of the filter plate 10 in the holding of the fine movement plate, the air flows out
through the through hole 9 of the filter @ 10, especially the speaker The resistance system-The
most conspiracy I4 wave area which is an area, and the high-pressure limit frequency can be
seen and it is to use for viscous resistance or f'II of ?. As a result, as shown in FIG. 2, the virgin
soil-horse wave number characteristic is flat as shown by a broken line as compared with the
characteristic of the i-speaker provided with the 74 lutter board 10 (received by a broken line).
Toh h ain at ah. However, with this o-6Co filter 1j10, only constant O inertia can be obtained, and

if it is intended to obtain a different degree of inertia, the ai and e large scale 1 are changed to
make another filter plate 10 with another K11. Sound pressure-It is not something that can be
controlled freely. The present remark is intended to eliminate the above-mentioned more
conventional drawbacks. As described above, in order to refer to the present invention with
reference to FIG. 1 of the drawings of the embodiment, 14 is a field section, and this field 11114
is a plate 16, 1 having a sensor pole 16 The ferrite magnet is composed of a single ferrite
magnet, and an upper plate 180III layer of the same spindle shape as well. The field section 14
shown here is an external magnet mk * 11, but it is composed of a columnar magnet, a pole
magnet and a center pole embedded in a + 1-, and is composed of nine internal magnetic types. It
may be field-. The frame 1sI is integrated with the field 1lA14.
The rim 1111c of this frame caster 9 has a gasket 20 and a conical micro-motion plate 21
installed, and a large number of bores 112-1 and 4 are rubbed in a brass form on the gasket
.lambda. @@ am is sloped, and the gasket 24 is attached to the peripheral tin of the plate of RIU
of RIH. Further, on the center-bottom surface of the upper Ell motion plate 21, the middle-turtle
is held by the damper 2 @ and is aligned with the nine-poise coil 2 so that it is correctly disposed
in the magnetic gap of the field section 14. It's gone. Because eight dust caps are attached to the
center upper part l1ii of the Oml glass plate 21. Furthermore, the above filter @ 2--upper 1iK has
a fixed interval and is attached with PHIIn's fill red-con) roll & ?-. Also this filter table-control
award-plate 2SK, filter plate agate plate and four through holes 29 uniformly! l formed, Vieuxrice! Please keep in mind that the sO through hole 22 will be completely closed, and if it is the
same thick hole 1 as the through hole 112. It is formed to a greater size than that. 1 to 1 and R #
of filter control # JI2 to 74 # T-M2s is fixed by a bead s1 through a spacer ? O so as to be 1%
well, 4? 61 Also, only the pooler control board 2 иии mounted on the buoy ha-? 23 with a reverse
O abduction torque so that braking is possible with I'th 114017t + filter control 1i 211 + filter
board 23 -It may be as large as it is, as shown in the drawing, it may be large angle equivalent to
the central part of the filter 2J, or it may be shaped like an elephant so as to honor only the field
of the filter @ 280% M1. The O-speaker of the present invention, which is configured as
described above, is VCIII. The hole 22 in the filter plate 2 sf) 1 and the hole 29 of the filter
control plate 28 completely coincide with each other. The braking effect by the filter plate 2s is
too little. In the case where the light inspection KM, 1 destination is one hole minimum C], the
sound pressure-frequency characteristics as shown by the solid line and the 1 function, and this
solid line and the dashed line O hatching @ Skill number threatened slI ? becomes ?. In this
way, the speaker of this note is the best jlr) characteristic 9 snow quality or selection, the filter
