BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a sectional perspective view of a conventional
speaker, FIG. 2 is a top view of a recently developed damper, and FIG. 3 is a sectional perspective
view showing one embodiment of the speaker of the present invention. A E: Voice coil 22, 22,

DETAILED DESCRIPTION OF THE INVENTION The invention 4g 4 "4 km, x f) dust") to provide a
stable, stable characteristics of the peripheral characteristics over a long period of time; It is. As a
speaker poisoned in the past, it was fortunate that IJ 81-was # 1 built, that is, the center brush
(1) inside the shoulder (1) through the magnet (2) 4) Add the L48-111A'l-n 2'- ° plate (6)
together with the 4's 41% to the top of the “Cafure))” together with the 2'- ° plate (6). The
voice coil (7) is supported by the MFL at the center line of the animal (6) and the damper 11 (8)
in the voice coil 17+, and the coil ii '+ of the voice coil (7) Of the magnetic gear, (9). In the upper
part of the voice coil (7), dust dusters Y-B are defeated. In the above-mentioned configuration, the
damper 4a) is formed by immersing a phenol 絢 旙 in silk 絹 cotton nato cloth and forming it in a
wave shape, so that it has a sufficient "effect" for dust prevention. Become. However, recently, for
the purpose of measuring high power output and simplification of production, as shown in Fig.
Ll52, a double bar is composed of a composite bR and a wooden IIII plate a〃, and two synthetic
quarter plates). 、, 参 の 長 の 長 4 形成 仲 2 2 が あ る が あ る が あ る 仲 There are 4 to 54

(7) is driven, a resistance is given to 3 to deteriorate the frequency physical properties or to
generate% JI # sound. Was a favorite thing. This J 346 eliminates the above-mentioned
conventional drawbacks. This will be described with reference to the drawings of the first
embodiment of the present invention. (2) is a corner IMB-, and inside the two h-shaped yokes, a
magne, a toe and a center ball .omega. Thus, the field 5 (2) is formed. Uni indicates the inside
aIM, but it may be the outside am field 1hli. In addition, a frame a is centered on the upper part
of the square yoke (d) of the second field a, and a central image portion of the frame 0 is a gasket

voice coil object In the second 7 dusts, the middle part is attached to the middle part of the voice
coil and the peripheral part is attached to the damper 1-. Furthermore, a dust caster is on the top
of the voice coil. Boo is covered and constituted. . In this way, a composite-oil disc is formed by
forming a spiral long hole, and a gauze grit is attached to the nine dampers. At 1 o'clock dust and
iron powder, etc., a magnetic gear with a voice coil. No entry at all,-permanent leaves due to
gypsum rubbish, etc. are completely discussed. Moreover, according to the second configuration

4 advantages of simple construction, and eliminate the generation of abnormal noise due to
rubbing with a static air gap of 1 °. , -59 ° house nine, two spinning one table, the voice coil

enable adjustment of the circumference 4B-10434-055 wave number characteristics. As in the
case of home-based speakers, they have great advantages and are of great value. 4, aAm One Fist
