DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a speaker
constructed by incorporating a high-pitched speaker into the low-pitched speaker tt, and in
particular, to the speaker, which is mounted between the high-pitched speaker holder and the
cone paper. The quality of the dust camp is to be improved by adding an improvement to the
dust camp attached to / -3 "2. A conventional speaker of this type is configured as shown in FIG.
That is, the frame 6 is coupled to the magnetic circuit 5 configured by arranging the ring-shaped
magnet 3 and the upper grate 4 on the plate 2 having the ten pole 1, and the cone along with the
gasket 7 at the periphery of the frame 6 The peripheral portion of the paper 8 is adhesively
bonded, the voice coil 9 is coupled to the central portion of the cone paper 8, the middle portion
of the voice coil 9 is held by the damper 10, and the lower portion of the voice film 9 is A
speaker for low-pitched sound is constructed without eccentricity to the magnetic gearing 11 and
the high-pitched speaker holder 12 is mounted on the center pole 1 of the magnetic circuit 5,
and the high-pitched speaker 13 is mounted on the high-pitched speaker holder 12. The dust cap
14 is attached to the middle portion of the high sound speaker holder 12 and the upper surface
of the central portion of the cone sheet 8. The dust carriage +: '+ J no 14 is formed by
impregnating a cloth with a synthetic resin to form a few cor 3 greens, and furthermore, it is
adhered to the high sound speaker holder 12 with a short bonding margin. There is a drawback
that the vibration of the cone paper 8 does not have sufficient followability, it is easy to peel off,
it is greatly influenced by the bonding degree by the adhesive, the positioning is difficult, and the
vibration of the cone paper 8 is adversely affected. The present invention seeks to eliminate the

above-mentioned conventional drawbacks. Hereinafter, an embodiment of the present invention
will be described with reference to FIGS. First, in FIG. 2, the basic configuration is the same as
that of FIG. 1, and the difference is the configuration of the dust cap 14, so only the dust camp
14 will be described. The dust cap 14 has a plurality of concentric corrugations 17 rising from
the joint portion 15 with the cone paper 8 by means of ethylene propireno rubber via a center
ring 16 and is to be connected to the high sound speaker holder 12 With the rising portion 18
along the periphery of the high-pitched speaker holder 12, the holding portion 19 engaged with
the upper end of the high-pitched speaker holder 4-12 is provided at the upper end of the rising
portion 18 of this). ing. Therefore, the adhesive bonding area to the high sound speaker holder
12 becomes remarkably large and the positioning becomes accurate, and the high sound speaker
holder 12 and the dust cap 14 can be connected in advance.
Further, the holding portion 19 of the dust cap 14 may be mechanically held by the high sound
speaker 13 and the upper end of the high sound speaker holder 12, and peeling by the vibration
of the cone paper 8 is further eliminated. Furthermore, since the dust cap 14 is made of a rubber
material, it is rich in the ability to follow the vibration of the cone paper 8-and it is heavy so that
it can be a mass dump material and the resonance can be damped to stabilize the characteristics.
Can also be That is, as shown in FIG. 3 (as shown by the solid line with respect to the
characteristic of the conventional speaker shown by the broken line, it is possible to make the
sound and frequency characteristics extremely flat. As described above, the loudspeaker
according to the present invention is improved in the workability in assembling 9 the
improvement of the quality, the improvement of the characteristics, etc., and the great effect is
achieved and the practical value is large 7'5.
