DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a loudspeaker
diaphragm. Conventionally, in the 1111w1 type speaker, as shown in FIG. 1, voice coil A / (1)
paste-on fiber (2) is soldered on cone paper (diaphragm) (3), and is soldered (4) K in advance It
was soldered to the end of the attached gold wire (5), and an electrical connection was made
between voice coil 7L / (1) and terminal (6). However, according to this, as shown in FIG. 2, the
application of the part (71d strength agent (8)) causes the solder to swell up from the surface of
the corn paper (3), and the appearance is not good. The fitting position of the dust cap (9) or its
size is limited, t! Stop on corn paper (3) (4) Caulking position, corn (1) :! ー, ー / / 〆 ;, jy-? ,.
There was a disadvantage that it was difficult to move freely because it hit the other part of the
gold thread machine (5) at the time of the vibration of one pair (3). The present invention
provides a speaker diaphragm e that can eliminate the above-mentioned drawbacks. Description
will be made based on FIG. 6 to FIG. (Ill is a diaphragm according to the present invention, in
which a four-piece weir that connects the voice coil lead wire Q21 and the gold wire H is formed
on the surface. Then, the bottom part (14a) of the above-mentioned recess-is crimped by 0
phrase, and the voice coil lead #! The connection between the government and the gold thread
machine I is made by soldering ill. Therefore, the surface (11 &) of the diaphragm (11) after
connection disappears due to the solder for connection (A) and the reinforcing agent Uη, so that
the adhesion part of the dust cap state (not shown in FIG. 5) 185L) can be positioned on the
connection portion between the main coil wire and the gold wire I. As described above, according

to the creation of the speaker of the present invention, since the recessed portion for connecting
the present coil lead wire and the gold thread wire is provided in the temporary table 1 km, the
voice coil lead wire as in the prior art is provided. (2) 9) and 金) with a gold thread machine-No
build-up due to solder and reinforcing agent can be eliminated, so design and assembly
restrictions on the shape, size and bonding position of the dust cap The appearance of the
speaker also improves.
