DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a speaker in
which a diaphragm and a dust cap are integrally formed, and improvement of the assembly of a
voice coil to this diaphragm to improve the stability of performance and high frequency 7- It is
an attempt to provide something superior. ///、? In general, the speaker was constructed as
shown in FIG. That is, the frame 6 is coupled to the magnetic circuit 5 configured by
incorporating the ring-shaped upper plate 4 in the same manner as the ring-shaped magnet 3 on
the plate 2 having the center pole 1. The peripheral portion of the diaphragm 80 is bonded by
bonding, the voice coil 9 is coupled to the central portion of the diaphragm 8, the middle portion
of the voice coil 9 is held by the damper 10, and the lower portion of the voice coil 9 is the
magnetic circuit 5. The magnetic cap 11 is fitted without eccentricity, and the dust cap 12 is
provided on the center -L surface of the diaphragm 8. Among such loudspeakers, those in which
the diaphragm 8 and the dust camp 12 are integrally formed to extend the high region are also
put to practical use. In the speaker in which the diaphragm 8 and the dust cap 12 are integrated,
as shown in FIG. 2 and FIG. 3, the voice coil 9 is incorporated into the magnetic gap 11 of the
magnetic circuit 6 without eccentricity. The adhesive 13 is applied to the upper end of the voice
3 coil 9 and the diaphragm 8 having the dust cap 12 is incorporated from the L side to connect
the voice coil 9 to the circumferential surface of the dust cap 120. However, in this configuration,

it can not be confirmed whether or not adhesion between the diaphragm 8 and the voice coil 9 is
performed reliably, and the vibration of the voice coil 9 is transmitted to the diaphragm 8
through the dust cap 12. Therefore, it is difficult to obtain high performance because the high
region has to be cut by the shape, so the high region must be reproduced only with the dust cap
12 and there is a phase difference with the diaphragm on the outer periphery. there were. On the
contrary, as shown in FIG. 4, although the thing which adhesively bonds the voice coil 9 to the
diaphragm 8 side is also considered, 1 confirmation of the adhesion condition can not be
performed, and also the state of high cut to the dust cap 12 The vibration can not be transmitted
and there is a drawback that the high frequency can not be extended sufficiently. The present
invention also eliminates the above-mentioned conventional drawbacks. 4t '-The embodiment of
the present invention will be described with reference to Figs. The overall configuration of the
loudspeaker is the same as that shown in FIG. 1, so only the features of the present invention will
be described here.
That is, the flat portion 14 formed at the boundary between the diaphragm 8 and the dust cap 12
is provided with an arc-shaped slit 15 into which the projecting portion 9b provided at the upper
end of the coil bobbin 9a of the voice coil 9 is fitted. The projecting portion 9 b is inserted, and
the adhesive 13 is applied to the upper surface of the flat portion 14 to connect the diaphragm 8
and the voice coil 9. With such a configuration, adhesive bonding between the diaphragm 8 and
the voice coil 9 can be completely performed and visually confirmed, and the voice coil 9 is
coupled to the middle of the diaphragm 8 and the dust cap 12 Therefore, the flat portion 14 is
filled with the adhesive 13, so that the vibration of the voice coil 9 is attenuated and transmitted
to the diaphragm 8 and the dust cap 12 to extend the high region. 6 · r =, as described above, the
speaker according to the present invention is configured, so that the characteristic of integrally
forming the diaphragm and the dust cap can be sufficiently exhibited, and the state of adhesive
bonding with the voice coil can also be confirmed It can provide excellent high frequency with
stable performance, and is of great practical value.
