1,-Name of invention
Domed speaker and its device
3. Detailed Description of the Invention In the present invention, a semi-hemispherical diaphragm
is used for the annular edge member! In this case, a sheet material for the layer 7 is used for the
speaker 7 for pressing the φ layer on the edge member, and n: J plate is applied to the edge
member. In conventional stereo systems, a dome-shaped speaker is used for sinking to improve
the frequency characteristic of the separation. Then, based on m, tt-FIGS. 1 to 44 of a
conventional dome-shaped speaker. l1ll! Light up. The dome-shaped speaker t-constituted yoke,
permanent d-stone, etc. are omitted. FIG. 1 is a cross-sectional view of the main part of the domeshaped speaker (1). The diaphragm (2) having a ball-like shape and the edge member (3) having
a loamy shape are integrally formed. In the above edge member (3), a part (4) of a semicircular
end page: spherical shape is integrally formed as if the exciting (2) is uniform -rt. Then, the upper
end of the cylindrical bobbin (6) is brought into contact with the inner peripheral surface portion
(5) of the bending position of the above edge member (3) and the diaphragm <2), and the outer
surface of this bobbin (6) The voice coil (7) is turned to gold. In FIG. 2, the hemispherical
diaphragm (8), the edge member (3) and the bobbin (6) are separately formed, and these three
members are formed by the inner peripheral surface portion (5) of the edge member (3). Fi to
weight! ! Voice coil (force is turned gold) on the bobbin (6). In the third figure, 7 flanges (8a) are
integrally formed on the outer side of the open end of the hemispherical diaphragm (8), and an
edge of the 7 flanges (8a), for example, an upper surface, is formed. . Increase the inner
circumference of member (3)! In addition, the lower end of the above-mentioned 7 lunge (8a) is
coated with the open end of the Etsu-wise sleeping voice coil (9). In addition, the upper eye selfwinding wound voice coil (9) is a material t of a rectangular section. It is easy to wind, laminate,
and fix using a layering agent, and a 6 L bobbin or the like is unnecessary. Thus, in the domeshaped loudspeakers constructed as described above, in any of the loudspeakers, the bobbin (6)
and the voice coil (9) are directly φ-layered on the diaphragm (2) or (3). Therefore, the
compliance (the soft name of the spring) t between the diaphragm and the bobbin or bobbin coil?
It can not be chosen arbitrarily, and it can not prevent the bad shadow 1 # of the division
vibration from tR ship to a bobbin or a voice coil, and it is a friend. Therefore, in the prior art, socalled "avale soul comfort" is generated on the multiple frequency pattern due to the interference
between the am plate and the edge member, and this is caused by the sudden increase of the
height d at the height as shown in FIG. There is a direct damping.
It is unnatural to buy a sound. The invention does not invent the defect 1 of the above-mentioned
item, which is invented by Himesho. It is an integral part of the method, for example, forming
integrally a spherical bulging portion made of rubber material on a cloth. The shave part of the
part has a Y + *-like shape, for example, a diaphragm formed by forming an aluminum basement
in contact with the diaphragm type, so that a voice coil is wound by winding a voice coil. And a
dome-filled speaker in the vicinity of the connection portion with the above-described edge
member, and a spherical-shaped output having a semi-spherical surface and a top cut off for
producing the dome-shaped speaker. A device for relatively JJQ pressure-bonding the abovementioned edge member having a unique shape in which the “b” portion is integrally formed
on the inner and outer peripheral portions, and the 儂 Ta plate having a to ′ ′ i-spherical
surface, A plate is placed on the lower die which has a circular disc-shaped diaphragm receiving
surface and the outer periphery of the lower die. A middle noodle having an end member

of the top of the bulging portion of the edge member against the periphery of the diaphragm; Of
the upper plate having the pressing surface, the upper plate of the upper plate and the edge
member in the lower plate and the middle plate, and the upper plate with the upper pressure of
the upper plate in good condition. The bulging portion of the member is made to have a pressure
of 1 more, and it is 5 nt = s * direct of the friend dome hollow speaker. Next, a nine dome speaker
(IJ and its construction) will be described based on FIG. 5 to FIG. The same reference numerals
are attached to the same # 1 road portion as the conventional weir, and the explanation thereof
is omitted. First, the structure of the dome board speaker (1) will be described. FIG. 5 shows the
first embodiment, in which an edge member uI wire cloth such as cotton, silk etc. is impregnated
with a rubber material and phenol resin h **. The ball 9 is formed into a concession using tl-, and
the top is notched at the inner peripheral portion thereof, and a bulging portion I having a y
hemispherical shape is integrally molded. (In this edge member, a half hemispherical damper 5
(4) is molded to one weight. The outer periphery of the damper part (4) is 0 in 7 runways. The
peripheral portion of the hemispherical diaphragm tta is image-layered on the inner surface of
the apical periphery of the bulging portion I, and both of them form a # PPb0 dome-shaped
speaker (1). The vibration 112 is formed using a metal, for example, an aluminum alloy, titanium,
or beryllium additive. One end of the cylindrical bobbin (6) has a hard layer name n on the
circumferential surface of the bending straight line with the edge member (kl (2) bulging portion
This Boppy / (6) is made of paper, metal, or an integral molding using Kosei resin temple, and a
voice coil t 'is wound on a predetermined iM: & of the EndPage: 21111 surface. It has been
turned. The open end of the diaphragm 0 and the-喝 of the bobbin (6) are separated by a length l.
For adhesion of the edge member to the diaphragm @ and the flange 6, for example, a synthetic
rubber adhesive is used. In this way, the sound of the friend dorm speaker (1) is sent to the voice
((7) and the signal 流 is 1 JL f 'LA, and this 46 No. 4 corresponds to the strength and weakness of
the vibration & (L4 is up and down It vibrates in the direction diagram, and thereby generates
the f voice. At this time, divided vibration and the like transmitted from the diaphragm to the
bobbin (6) are transmitted by dividing the bulged portion 1D of the edge member. Therefore, by
selecting the material purchase of the edge member uQ, it is possible to select the compliance of
the bulging portion (11) with great care and extremely easily. And thereby, the transmission of
the above-mentioned divided vibration etc. is reduced to pressure, and the resonance
