BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a half sectional view showing a conventional
speaker, FIG. 2 is a sectional view showing a conventional skier system, and FIG. 3 is a half
sectional view showing one embodiment of the speaker of the present invention FIG. 4 is a sound
pressure frequency characteristic diagram when the same speaker is used as a system. E и

[Detailed description of the invention] 1 specification 1 title of invention 2 claim category of the
utility model claim 1 the chest II Wi (diffraction diaphragm equipped with passive radiator is
attached d1 to this frame coupled to the field section A speaker configured by hanging a voice
coil on l1ll @. 3.1 draft 1 o NII & I! The present invention relates to a speaker provided with a
low-profile regenerative speaker (only for the low frequency reproduction) at the peripheral
portion of the diaphragm, in which the minimum resonance frequency is lowered to improve the
low frequency characteristic. -As shown in Wllll, the speaker is equipped with a crown plate 2
and a ring-shaped magnet 3 as well as a ring-shaped magnet 3 and a ring-shaped upper plate 4
as shown in Wllll. Attach the diaphragm 8 with the gasket 7 at the edge, and wind the voice coil и
around the center of the diaphragm 80 = 2 pcs of ai bobbin 1 o suspended, 1 lb of this filament 1
Q Qy in Mlb & da / bar 11 It is constituted by pasting a stub 12 and a tub 12 in the central part
of a support, a case, a work, a work and a + '1111. The scaker smell which is composed of this-(,
the number of reciprocable points per period is the diaphragm 8, the voice coil 9, the weight of
peristaltic accessories such as Ilbobi 710, = 7 pliers of the vibrating rod parts 7 The lowest
frequency determined by the area of Sui Jie 8 etc. is the frequency io. If the number of
resonances is limited to 7 o without raising the output pressure, it is limited to the number of
resonances 7 o. I'll tell you once. Because of this, f! As shown in FIG. 12, for the slider 14
attached with a sliding cover 13L, the one with a phase BLk doconconor slider 16 14jN is used,
or the mounting of the tact is large. ', From the surface of the table, like'-h 'm son-' install beakers

and one, and the strike is extremely disadvantageous in terms of cost. This discussion m is
intended to eliminate the above-mentioned conventional drawbacks. Hereinafter, the present
invention will be described with reference to one embodiment og *% mgm +. 1 и The field am he,
? o field aII 16 d-ky 1-ball 17 equipped with a large plate 1 a, phosphorus l-like O magnet 19
and Okaji (Linder-like O over play) 20 e laminates It is made up of In the O-field part 16, a
conical part 121 is formed, a peripheral flat part 22 is wide, and a flat-fi upper part 22 is
provided with a window gtag to condense 7 lame nitrogen 4 For this reason, at the boundary
between the ?O frame 140 cone and the flat weir 22 is formed by a fold, and the center # 26 is
formed, together with the O assembly 2 BIC Gastat 2 и called as the excess NO cone cone 4 1 2
adhesive glue lll 1 in 1 lives, further, the peripheral edge of this 0111 11 111 ? 170 is formed
with two corrugations n ia, 5et-') 4 od o, and the frame 24 is flat When it is moistened to s22, the
abrasive 7I11 crane is fixed to the circumferential end of the flat portion 220 by the gasket 30.
The vibrating plate 270 in the two GtJ pockets 26 and SO 2 is referred to as a badge brush eater
31. And 11 m2 of weight is attached to the underside of this passive radiator S10. A coil bobbin
34 on which the voice coil 8s is wound is suspended at the central portion of the vibration fI27,
supported by an intermediate portion damper SS of the coil bobbin s4, and a central sIc of the
vibration @ 2 is dust Because the cap s6 is brazed. By configuring the speaker in this manner,
when attached to a speaker cab or the like, when the diaphragm 2 is vibrated, the fluctuation of
the back WO air pressure of vibration @ 27 is transmitted to the badge brush eta s 1 through lK

according to the present invention is compared to one using a conventional general speaker as
shown in FIG. Can be a sound pressure debris characteristic as shown by a whistle, and by
lowering the output sound pressure level, it is possible to reduce the lowest resonance frequency
by fIo. As described above, the speaker according to the present invention has the same function
as that of the speaker provided with the duct inside of the box incorporating the 1lc) 'Roncone
speaker embedded in the box by providing the passive radiator on the peripheral edge III of the
vibrating rod. It will be beaten with one piece, extremely i! At the same time, it is possible to
improve the low-m characteristics and to measure the practical value at once. 4.11 Brief
