DETAILED DESCRIPTION OF THE INVENTION This invention relates to a speaker edge for
attaching the outer edge of a conical cylindrical diaphragm to a frame in a speaker. In the
conventional speaker edge, as shown in FIG. 7, woven fabric made of warp and weft yarns is
resin-processed and used from the left, firstly there is directionality in the fabric, and tenthly
resin-processed. On the other hand, both of the frosts 9 of the W resin emulsion were small, and
thirdly they had a number of disadvantages derived from the first and second factors. Therefore,
this invention is made for the purpose of eliminating the various disadvantages of the system.
Hereinafter, the present invention will be described with reference to FIG. 1 which illustrates the
present invention as an example. (1) is a speaker edge according to the present invention, in
which a knitted fabric is braided with synthetic fibers, and then subjected to priming and
appropriately cut. The cut cloth is cut into an annular shape consisting of the rim (2) and the
outer rim (4) and the width of the rim of one rim (2) is an outer rim 13 of the conical cylindrical
diaphragm (3). A connection part (1) a which is appropriately polymerized in a middle, and a
connection part (1) which is formed by overlapping an appropriate width around the other outer
edge (4) to the attachment part (5) a of the frame (5) , The middle part fl) c of which is formed by
bending the cross section into a substantially semicircular shape at the time of connection with
the diaphragm, and the outer edge (4) of the speaker edge is the diaphragm (3) It may be cut at
the time of polymerization adhesion to the surface, and it is stamped at the time of the adhesion
to bend the middle part into an annular ring shape. Curing the resin with concomitant Infiltration

into knitted fabric, in which may be maintained in the curved state. As described above, this
invention is a knitted fabric in which the engineering O material is braided with synthetic fiberone shoulder and 7 fine yarns, so it has better formability and lower temperature than
conventional canvas made of natural fibers. It is possible to process the middle part of the curve,
and it does not weaken the knitted fabric. In addition, since the knitted fabric has no
directionality unlike the woven fabric, and because the resin storage capacity is large compared
to the woven fabric, the entire edge can be finished with softness, and the connecting portion on
the diaphragm is Front and back are soft and smooth, there is little vibration from side to side,
moreover, there is no resonance with the diaphragm, so it can not be borrowed for the sound
quality characteristics, and since it does not cause elastic fatigue, it has excellent sound quality
characteristics semipermanently Have an effect that can be sustained. Depending on the effect
25) 'can provide a good sound quality speakers.
