[Detailed description of the device] Wood device is of Bleetz! -In relation to the Itakura use 几
speaker, corrugating the cone Il of omelette vinegar with the adhesive of the edge and the cone
sometimes. 2 m, and here the extra adhesive agent kR t-t has the same properties as above, and it
is intended to prevent adhesion between diaphragms in production a4. In the speaker, as a
diaphragm 74. It is well known that two types of Kusudo type, 7 Leiji, and Shiteibu are often
used. Among them, the tree edge type can be freely selected as a soft one or hard five, etc. as an
edge, but generally it is a minimum co-shooting as a speaker using a soft b material 2, t ′ ′
of 2 ′ ′ 7 ′ ′ 2 Good number f. It is configured to lower V. For example, an eaves formed by
forming a gauze and forming a nine cone cone cone or a foamed tree m, a nine cone cone cone, a
cloth impregnated with a rubber-based impregnating agent, and an thermoplastic resin 11
formed by a gutter The pieces are pasted together with a gutter to make up I / '. In the
diaphragm of such a configuration, conventionally, as shown in FIG. 1, the inner edge portion of
the edge 2 is bonded with an adhesive 3 to the circumference l & portion of the conical cone 1.
In order to melt the paste, it is necessary to apply an adhesive 3 to the surface of the composite
and press the cone 1 and the edge 2 so as to make a% contact. However, due to the pressure of
the cone 1 and the edge 2, the excess adhesive 3 comes out of the 1 itlfi and comes out directly
on the cone 1 and the edge 240411. This protruding adhesive 3 reinforces the upper edge of the
cone 1 to form a speaker, and in the sound pressure frequency sensitive characteristic there is no
dip in the region, and a flat characteristic is obtained easily. It will be. However, by sticking out
the sticking agent 3 in this way, a plurality of II-year-old plates are stacked in the process of
producing the speaker, one by one is taken out at the time of assembly one by one, and
incorporated into the frame. With the adhesive 3 taken out, the stacked nine upper and lower
plates are adhered. It takes time to peel off the adhesion! ! At the same time, when it is removed,
it is possible to damage the 2 to y 1 or to damage it if it becomes a serious Ic. Therefore, it is
conceivable to reduce the application 1k of the adhesive 3 as in the case of the adhesive 3
sticking out and & A, but if the amount of the adhesive 3 is small, the two 71 and the edge 2 will
be sufficient. It could not be tied up, leading to a drastic deterioration of the characteristics. The
present invention eliminates the above-mentioned conventional drawbacks.
Hereinafter, the present invention will be described with reference to FIG. 3 and FIG. 4 is a field
section, and this field section 4 is of the so-called external magnet type, and is a ring 6 having a
center ball 6, a ring 6 and a ring magne It is constituted by the upper plate 8. In addition, as the
field part 4, even if it is a fe% which incorporates magne, toe and a center ball in the yoke. In the
field g4, a frame 50 is coupled n, and an end 11 & 11 together with a gasket 10 are coupled n at
the @ edge of the 7th rim 9. The voice coil 12 is wound around the central portion of the
vibration @ 11, and the nine coil bobbins 13 are suspended. The middle portion of the-coil
bobbins 13 is supported by the damper 14 and nl of the diaphragm 11 is centered The r1F
stocker and the pump 16 are attached to the base and m are mounted. On the other hand, Kamiki
digging 111 is a free water type pipe in which a cone 1 of a conical shape and a work, and a die
17 are adhered with an adhesive 18. As shown in L1m4, a part of the mittm of this cone 16 and
the work, the di 17 or the bite of the thin surface as shown in FIG. The m center of the cloth
adhesive 18 is sometimes used as the recess 2 ° Km of the corrugation 1e. In the case of n, the
compensation of the concave portion is completed by the total of n + this concave $ 20 adhesive
agent 18, and the excessive polishing operation to the di 17 is cut by n, completely by preventing
the reworking and the di resonance. In addition, the adhesive 18 gets caught in the recess 20 1,
so even if the recess 20 has six contacts 4 out of the surface, it will be vibrated even if it is
presented at the time of assembling the diaphragm 11 t-knowledge. There is almost no chance
that the boards will be praised 9. Damage to the diaphragm or inferiority of the f-like thing can
be considered as a complete iC K lick. Furthermore, by providing this concave% 20t-. The
adhesive agent 181i can be fully mounted on a car, and a strong bond between the I-n 16 and
the tool, and the screw 1 can be completely removed with a total of n and cling. As described
above, the speaker of the present invention has various advantages and is practical--large in size.
