BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a plan view of an arrowhead for speakers
according to the present invention, FIG. 2 is an explanatory view showing a continuous cutting
state of the arrowhead for speakers according to the present invention, and FIG. Explanatory
drawing which shows the material after punching of the arrow force paper, FIG. 4 is explanatory
drawing which shows the state which attached the arrow paper for speakers of this invention to
the flame | frame of a speaker. 1 ииииии Arrow for arrow Fig. 1-403-Japanese Utility Model

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an arrowhead for
a speaker fixed to a frame of a speaker to fix a diaphragm and to provide a buffering action.
Heretofore, the arrowheads for speakers have been rJ extracted and teared by using an att L *
chip ball extraction die according to a desired thickness. In this Jy method, from the structure of
the blade of the d1 die-cut die to the eyebrow, the outer surface of the chip ball of the outer ball
is not easy to eat, or an arrow as shown in 3 [% j! The yield of the 9 V chip ball having the IXC
inner arc and the outer arc in the concentric 1 и Ill shape is extremely poor and the cost is high 0,
that is, the outer arc 22 and the inside (0 @ 23, end Q124.24 And the outer arc 22 and the inner
arc 23 of the arrow 21 formed from the inner core 23 is a part for the inner core, so that the loss
portion 25 is inevitable in the other arrows ... punched out by another neighbor. As a result, the
yield of the chip ball is as bad as 44 w. Furthermore, since the conventional one uses a thick
blade with a thickness of 9 but it is relatively close, and it is virtually impossible to make a single
die that allows simultaneous punching many times, so 1 in the punching process I went to punch
out one by one, and I was frustrated with the efficiency of the industry. In the case of punching,
the punched arrowhead is retained inside the chisel, then pushed upward by the thickness of the
punched arrowhead, and thus pushed in this way one by one. It is frozen because it is a book
taken out from above, but if it is not formed wider than the blade width at the upper end in
general, the punched arrow sheet receives resistance from the surrounding as it moves upward

and deforms It takes time and effort to carry it out. However, forming the t-sl11Q-2 * RAn-n'3
upper part wide in the width means that, when arranging the lapping plates, the juxtaposed
position is constrained by the upper part of the adjacent lapping plates. As a result, the loss s26
is increased. The purpose of the present invention is to ameliorate the drawbacks mentioned
above and to provide an easy-to-process speaker arrowhead. Next, the speaker arrowhead of the
present invention will be described based on the drawings. According to the present invention, as
shown in FIG. 1, it is composed of an outer arc s2, an inner arc portion 3 and an end portion 4.4.
The outer arc s2 and the inner arc 3 are formed with the same curvature, and are formed in a 4
to 4 Fi city line. That is, as shown in FIG. 2, the required short shelf chip balls 5 are cut in
advance, and the chip balls 5 are cut so that the outer arc 2 and the inner arc 3 have the same
curvature. For this cutting, use a single cutting blade with the same curvature as the curvature of
the outer arc 2 and the inner arc 3, cut the part of the inner arc 3 and then cut the required
depth of the arrowhead or cutting tip The ball can be transferred to cut off the part of the outer
arc 2, which can be Ar5-li OAn-nA to obtain the arrowhead 1 in the manner of a grain. ? !

methods, there is no loss in the music of the adjacent central paper. As shown in FIG. 1 Ik, which
is formed in this manner, as shown in FIG. IK, the speaker frame lO is mounted in Yt through a
lossy phase (not shown) as a set of reference numbers 114j. Since this 4Z-period pi and the inner
arc have a voice 1-curvature, if the speaker frame 10 is mounted ? и и 1 auto 4 around speaker

material. ! In the manufacturing process, it is possible to cut a large number of loudspeaker
arrows into the same town in 8 h before making a 4 h-shaped and cutting 61 pieces at regular
intervals into a piece of material which has been pre-printed in one piece. In addition, it is
possible to cut the material with the blade group described in i1 and cut both sides of the
material later with a straight line to obtain a number of cocoons at the same time. It greatly
contributes to simplification 2.
