[Detailed description of the invention] 11. · Specification · 1, title of the invention 2, v! Place a coil
and II song magnet on the outer circumference 141 of this film on a plate equipped with a range
5 center ball outside of a new party baby O request, and a circle # on this magnet! In the part, a
plurality of projections protruding downward by the amount of air tight gap and a plurality of
diaphragms arranged, and 7) a movable 'fixed iron piece on the upper surface of the upper
surface of the cover' Hiroshi · 3, I think about the details # 8 of Zero X X device is the dimension
storage of the magnetic gap and the size <. And it's a simple electromagnetic type saturating
acoustic conversion ll5K-A6 as a C magnet type electro-acoustic electrolyzer in the conventional
A6. As shown in Quasi 11m, it was constructed 0, ie, center pole 1? Central management (On the
plate 2 equipped, 10 distributed Sen 4- pole 1 !!! So that the coil 3%, ring-shaped "e magnet 4?
The cylindrical diaphragm support 6 is attached to the blur 21 of the magnet 4 and the outer
periphery of the magnet 4, and the central IC pivoting iron piece 6 is t to the upper end of the D
sliding plate support 6. Magnetic association-peripheral edge of the diaphragm 7 made of thin
plate is softly placed, f) on the lower surface of the diaphragm support 5 H J & $ 1t) lead wire
and il! Terminal 8 to be jealous? Equipped with 9 terminals riIaI! II is arranged, 1-digit -10 is
transmitted by 10g ・ In such a constitution δl, it is generated when a signal @ current is
applied to the fill 3. Because of the fILfa field, a diaphragm In such l11 IT'II, the amplitude
between the diaphragm support 6 and the net 1. That is, the length of the ω air jr spike is
restricted. Since this magnetic map is about 0.1 鵡 in size, considerable precision is required nh.

However, with an advanced configuration! Gnet 4 and moving plate support 60th f11! At the
meeting to fix the clerk. As mentioned above, it is possible to put out the size of 0.1 size. 11
extremely difficult, a length of air + V +-3 [シ io 10 會 生 じ 生 じ v v v v こ れ こ れ こ れ こ れ

こ れ こ れOr 1 quality I1. Has become extremely unstable in terms of inertia-· The X device is
the above conventional defects? It is O which is removed, and below, 1 1 Explain according to the
drawing 施 2 施 2 11 is a center ball 12 '! -Integrally '+ VFil, on this plate 11 on the plate.
The fill 1s wound around the center ball 12 and the outer circumference l of the fill 13! The ringshaped D magnet 14 with a predetermined distance is placed on the tn ring, and then this
magnet 14 is sS, as shown in FIG. 116 arranges enjoyment. The moving plate 16 is formed of a
magnetic metal thin plate of high permeability, and a central portion tcti movable iron plate 17 is
fixed. 11 pieces, the above 16 prongs, at the time of production of the moving plate 16 "vc, Buch
etc. Dff! For example, the height of the deodorant. )41・l01o? ml!! Because it is
protected to be the height of warmth t, the gap between all · and the magnet 14 and the sensor Iport 112 by the height of this II @ 18, ie, the magnetic gap I is 4V . Then, they are placed in the
case 1S made of an insulator, and are stored in the case 1S, and the bottom i + itc has both the
coil 13 with the terminal 19 pulled out from @print tt, ± 4-plate 11, etc. In the case 1B, the
upper, lower, lower wVch, central 111C sound release hole 21%, and the force (−22) are taken
away. As described above, since the 甫 mm electroacoustic transducer m of the present invention
is structured by weight, the dimensions of the stand on the lower side can be controlled to
provide the rim of the worker's job 1 m-plate and magnet or center ball Between FJ, that is, the
dimensional control of the magnetic 1 gap is easy and sure 11! When the output sound pressure
level is stabilized by making the size of the magnetic gear 110 IR fixed as described above, both
the resonance frequency and the resonance frequency are stable. Variations are almost
eliminated, and improvements in characteristics can also be measured. Also, in terms of
configuration, the magnet works as a diaphragm support! -It is possible to reduce the number of
parts, to be able to achieve cost-effective and cost-effective, and to have a large practical value.
