DESCRIPTION JPS5151725
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a side sectional view of a conventional dome
type speaker, and FIG. 2 is a side sectional view of a dome type speaker according to the present
invention. Here, 1 is a permanent magnet, 2 is a pole piece, 3 is a plate, 6 is an edge, 7 is a frame,
an io + -g'-shaped diaphragm, and 'lQa is a top portion of the diaphragm. Fig. 1 Fig. 2-'55-
DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a dome shaped
speaker. The number of grooves is as shown in FIG. That is, in FIG. 1, it is an lFi ice matrix, 2α
pole piece, s # i plate, and is a bog connected to an air gap Kd dome-shaped oscillating plate 4
formed on the pole piece 2 and the plate 30 stop I. A coil 5 is inserted. 6 and 7 is an edge, and
the W1 moving plate 4 is supported on 7 frames 7 0 Generally, the dome-shaped speaker is
configured as described above, or in the dome-shaped speaker configured as above Dome-shaped
mouth diaphragm 40-system semi to be able to wipe out the wave number band! The height of
the crest is smaller than rt height of the crest with respect to the diameter of 畿 111I. There is a
disadvantage that the sound waves generated from the peripheral portion are shifted in time, and
this delay in time causes a gap on the characteristic of f 庄 at a specific IIIt number, which causes
a gap on the characteristic of f 庄. Now, [Pl, l of the general dome-shaped speaker of about 25
summer in the inflection diameter! It is old-fashioned that the top height of the # plate shape Is is
about 7 to 12 mm. ll) Size difference light 15 ˜ 20 kl for the top and the side of the leg. The
phase correction is performed by attaching a front cover 8Yt provided with an equalizer in front
of the L board 4 shown in the prior art. In view of the above points, the present invention
improves the shape of the 1 "dome-shaped wedge plate without using the A-colyzer pipe, and by
temporally shifting the sound waves generated from the top of the dome-shaped plate 1 and
pigeon side S by chewing. Anti-common oil) wave at ′ ′ ′ ′ ′ T * i 1 out of the hill, out of

example of the present proposal is shown in FIG. One factor of the invention is described in the

and as shown in this ■ ifl, the convex shape of the dome-shaped tf # plate lo of the domed
loudspeaker according to the invention lL ? The portion or top portion IQa is recessed so that the
cross-sectional shape is concave, so that the relative dimensional difference between the
peripheral portion and the center or top at the W # diameter is smaller than that of the
conventional loudspeaker. Since the construction rL of the other part in FIG. 92 is the same as in
FIG. 1, the transmitter 1-code tube is attached. The present invention is as described above.
Therefore, the relative dimensional difference between the central part (top part) and the
peripheral part of the toroidal wedge plate 1 becomes small, and therefore the sound wave
generated in the middle lLP part and the peripheral part is not The IXl also loses its character.
