DESCRIPTION JPS5611581
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a cross-sectional view of a conventional ring
speaker, and FIG. 21 is a cross-sectional view of the ring speaker of the present invention. 1.11 is
a diaphragm, 2 and 3.12 are clampers, 4 is a voice coil, 5 is a center pole, 6 is a magnet, 7 is a
plate, 8 and 14 are horns, 9 and 13 are equalizers, and 10 is a screw .
DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a ring speaker V
which horizontally mounts the central flat plate portion and the outer peripheral flat portion q of
the speaker diaphragm. Conventionally, as shown in FIG. 1, in the ring speaker, an annular
magnet 6 and an annular ring 5 // 2 rate 7 are attached to the center pole 5 with an adhesive to
make the magnetic circuit 1! ! And form an iC magnetic cap between the center pole 5 and the
annular plate 7. Attach the hose coil 4 at the inner solid edge of the annular V-shaped swing part
(˜, the disc-like clamper 12 on the lower surface of the central flat plate, and the annular cage /
bar 3 on the lower surface of the outer M part The diaphragm 11 is mounted on the top surface
of the center pole 5 that controls the magnetic circuit, and the top surface of the plate 7, and the
position coil of the Heus coil 4 is positioned at the center of the magnetic gear knob. A screw
hole is formed axially penetrating from the lower surface of the center pole 5, a screw hole is
formed at the center of the diaphragm 11 and the disk-like clamper 12, and a hysteresis screw
hole is formed on the lower surface of the equalizer 13 to vibrate Attach the Ukl equalizer 13 on
the center of the plate 11 with a screw V. An annular horn 14 and an NK 3 location screw hole
are formed, an outer plate 3 is screwed with 3 screw holes in the outer plate 7, and a diaphragm
11 outside the diaphragm plate 11 is covered on the upper surface of the annular plate 7 with a
hiss. Install At this time, there is variation in thickness between the annular magnet 7, the
annular plate 7, and the clampers 12.3 constituting the magnetic circuit, and the central part of
the center pole 5 and the island of the U side are Since there is no raccoon, there is a defect that
a step is generated between the central portion of the moving plate and the portion for external
use by the size of 5 ラ ノ キ ラ ラ ハ ロ ハ ロ ハ ロ ハ ロ ハ ロ ハ ロ ハ ロ ハ ロ ハ ロ ハ ロ ハ ロ

ハ ロ ハ ロ ハ ロ ハ ロ ハ ロ ラ. Moreover, when the step becomes too large and the dog becomes
a dog, it is necessary to adjust by inserting a spacer or the like, and the assembly man-hour is
also large. The present invention is designed to eliminate the above-mentioned drawbacks. The
embodiment shown in the drawings will be described in the following. Toro and the annular plate
7 are adhered with an adhesive to form a magnetic circuit, and magnetic gearing is formed
between the center pole 5 and the annular plate 7. A magnetic circuit is formed by pasting the
Heus coil 4 below the facing edge of the ring-shaped V-shaped vibration section, and combining
the disc-like clamper 2 on the lower surface of the central flat plate and the annular clamp 3 on
the lower surface of the external part. The voice coil 4 is placed at the center of the magnetic gap
by mounting the center pole 5 to be mounted on the plate 7 iK. Attach the horn 8 and the 1
equalizer 9 connected in multiple places on the upper surface of the diaphragm 1 and combine
and finish integrally the respective horns T 1 of the horn 8 and the equalizer 9 so as to be 4
times It is a ring speaker in which a hysteresis screw hole is penetrated in the axial direction
from the lower surface of the center pole 5 and the disc-shaped claper 2 is pushed up with a
screw 10 to bring the central portion of the diaphragm 1 into contact with the ink below the
equalizer 9.
The uninvented configuration is as described above, to the extent that variations in the method of
each component constituting the magnetic circuit can be absorbed. Since a gap is opened
between the K center ball 5 and the disk-like clamper 2, By pressing the -t-disc-like clamper 2
with a screw IO7, the central plate portion of the diaphragm lO and the outer portion are
positioned horizontally to prevent generation of distorted sound. The assembly process is simple,
and it is a useful device that is easy to clean.
