DESCRIPTION JPS50145342
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a cross-sectional view of a fixed edge, FIG. 2 is
a cross-sectional view of a free edge, and FIG. 3 is a cross-sectional view of the free edge of the
speaker of the present invention. 32 is an edge material, 33 is an edge paint, 34 is an edge 31 is
cone paper, and 32a is an annular standing piece. \−103−
DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a speaker having
an enon structure in which defects due to edge paint are all reduced at the time of speaker
assembly. In the conventional speaker, as shown in FIG. 1, the cone paper 21 and the edge 22 are
formed of different materials as shown in FIG. There is a free edge or the like that glued both at
the time of assembly. As the free enon edge material, foamable synthetic resin, leather, cotton
cloth, etc. is used, or from the 2 ° point of price and characteristics, the material 22
impregnated with synthetic resin into cotton cloth etc. and then heat-formed, has compliance and
mechanical resistance. Since it is necessary to keep an appropriate value, an edge having a
structure obtained by applying an edge paint in which a plastic synthetic resin such as acrylic
resin is dissolved in a solvent such as ethyl acetate is used. Therefore, paste the corn paper 21

a lot of stable products with high quality. 1) In the present invention, the flow of the end paint
□□ stop is provided on the innermost edge of the end, and the end paint adheres to the corn
paper or 1 is 60 ′ ′ permeable. It is a 6 'beaker that has 4 "and 7" 4 ". The present invention
will be described in more detail with reference to FIG. 3. The inner peripheral portion of the edge
34, that is, the innermost peripheral edge of the sticking portion with the cone paper 31 is bent
upward to form an annular rising piece 32a. According to the structure of the present invention,
when the corn paper 31 □ 3 and the edge material 32 are attached and the edge paint 33 is
applied to the edge material 32 and dried, the edge paint 33 flows out inward. Even if it is
stopped by the standing piece 32a, it can be prevented from adhering to the corn paper 31 or

permeating. At the same time, since the rigidity of the edge material 32 is increased by the
annular standing piece 32a, the deformation to the attachment to the cone paper 31 is
eliminated and it becomes very easy to store and handle. As described above, the speaker
according to the present invention can provide a stable quality product without any defects in the
edge paint coating process, and has practical advantages such as easy management of the age
material.
