BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing a junction between
a cone sheet and an edge of a conventional cone-shaped speaker, and FIGS. 2 and 3 are a cone
sheet and an edge of the cone-shaped speaker according to the present invention. It is a
perspective view which shows a junction part. 1

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a loudspeaker,
and more particularly to a loudspeaker with a cone and an edge and a junction which has been
modified. Conventionally, as shown in FIG. 11, a cone ? speaker in which a cone Ja (1) and an
age @) are individually manufactured, and their junctions @ (1 u), (? 1) and (? 1) are combined
entirely) If the work is a di (3) force XN or is softer than a cone paper, the vibration transmitted
from the voice coil is reflected by the edge (3), and the sound [EI # When natural vibration
occurs in 0 or ? V ?) that generates peaks and valleys, the vibration is directly transmitted to
the cone paper (1), and when the phases are in phase, the sound pressure peaks and 9 When
there is a gap, there is a drawback that the sound pressure is deviating. The present invention is
designed to ? -W the defect of 8 characters ? ?,-the purpose is that the reflection when the
vibration transmitted from the voice coil is transmitted to the cone paper) age To provide a Cau 7
type speaker with reduced Another object of the present invention is to provide a cone type
speaker which reduces the transmission of this vibration to cone paper when the characteristic
vibration occurs in the age. Next, an embodiment of the present invention will be described with
reference to the drawings. In FIG. 2, the junction with cone paper (1) with the surface of the
paper (1) @ (11) K serrated notch W (mouth a) is formed, and this junction (11) t age (junction of
ridges) Glue with It (tt) K adhesive. Also, in FIG. 3, bonding of the cone paper ? [(11) K radial
direction elongated hole (11 t +) and its base tll K1 * L-C #, e ? yes ? 3, 1 o, 2- formation It is
done. The bond @ (11) is bonded to the bond 1111 of ? ? di 0). As described above, since the
joint portion (u) K notch portion (11 m) of the corn paper (1) or the long hole notch 1t (ub) and
the round hole notch portion-(slo) are pierced to form a space 1illt, the age (12) In the joint filK,
the physical constant becomes an intermediate value between the cone paper (1) and the edge
(2). Therefore the vibration r! From corn paper (1) or edge (?)! It is attenuated and transmitted
at junction (ll) C10. As a result, the sound pressure beak and dip at frequencies higher than the
division frequency and at the specific imaging movement of the edge are reduced, and the whole
1I4a [housing property becomes flat. The saw-like notch 111 (1? and the long hole notch 1i (ob)
and the round hole notch 111 (ttc) are a combination of nine, but it is not intended to It is good if
it is an intermediate crease between a or c / (5) and the edge (2) Q or in the example, with a
sawtooth notch VIAC 11a) or a long hole notch (Ut +) in a cone paper (1) Although a round hole
cutout (1 to) is shown, it is possible to form a joint (? 1) K of an edge).
In the present invention, as described above, by making the junction between the paper and the
edge be at the intermediate position, the vibration transmitted from any of them is attenuated
and transmitted, thus the frequency characteristic is flattened. And other effects.
