BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram of a conventional planar
passive loudspeaker, FIG. 2 is a block diagram of a flat passive loudspeaker according to the
present invention, and FIG. 3 is a sectional view of a cylindrical body 2 with a vibro stuck thereto
FIG. 4 is a cross-sectional view of a cylindrical body 2 connected with a vibrator, FIG. 5 is an
external view of a semicircular plate 6 'attached to a cylindrical body 2, and FIG. 6 is a sectional
view of a stroke bearing. 1 is a stroke bearing, 2 is a cylindrical body, 3 is a diaphragm, 4 is a
damper, 5 is a frame, 6 is a pipe, 6 'is a light metal plate, 8 is a reinforcing plate, 9 is an inner
bottom portion, 10 is a center hole, 11 is a bearing ball. .
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention relates to
an improvement of a flat type cross / vibrating speaker placed side by side near the speaker for
driving the speaker box in order to enhance the bass range reproduction. Conventionally, as
shown in FIG. 1, the flat plate type bus sab diaphragm speaker sticks the outer peripheral edge of
the diaphragm 8 integrally formed of the edge portion and the imaging portion with the
synthetic rubber 2 to the peripheral portion of the frame 5 L% A light metal compliant
reinforcing plate 8 such as aluminum is attached to the back side of the imaging part of the plate
8 and the upper end of the cylindrical body 7 is attached to the center of the substitute plate 8
and the outer peripheral edge of the cylindrical body 7 is attached to the lower step Is held by
the damper 4 affixed to the part and held in the center. If such a half board type pannonve
diaphragm speaker 併 Spi - Carbonnox driving speakers are juxtaposed, it will resonate with the
air vibrations generated by the drive speaker (the diaphragm of this flat type passo / bass
diaphragm speaker Three are deviated. In this case, please use the self weight of the vibration /
assistance board 3 and use the outer diameter of the damper · t 80% 0% DAL 100 "Xn in order to
use the big one, turn the lamp on the diaphragm 3 and turn the cylinder 7 It is a disadvantage
that the damper 4 is deformed if it can be kept constant so as to make it stroked in the direction
of power direction O. Also, if the outer diameter of the damper 1 is reduced, the cylindrical body

7'f! : It was a drawback that the holding power to make it meter towards the protein force (until it
increases or the amplitude of the loudspeaker 3 is restricted to deteriorate the characteristics of
the speaker). 3 The present invention was devised as a method for preventing the vibration of the
diaphragm in order to eliminate the above-mentioned drawbacks and explains the embodiment
shown in the drawing, as shown in FIG. 2, the eno 7 parts and the deceptive part Is adhered to
the periphery of the frame 50. A light metal such as aluminum or a reinforcing plate 8 made of
synthetic resin is attached to the back surface of the diaphragm 30 and the vibrating portion is
attached to the diaphragm 3 Form. The child end of the cylindrical body 2 is affixed to the center
of the rear surface of the vibrator to establish the F part 1 and the outer peripheral edge of the
cylinder 2 is fixed by the damper 4 affixed to the horizontal step correction part of the frame 5
And is held at the center while being sandwiched by the outer periphery. As shown in FIG. 3, a
light metal metallic vibro is attached to the outer periphery of the lower end of the cylindrical
body 2, as shown in FIG. 4, or as shown in FIG. 5, the semicircular arc-shaped light metal plate 6 '
, And the lower end of the cylindrical body 2 to which the vibro or semicircular arc light-weight
metal plate 6 'is affixed is attached to the inner bottom portion 9 of the frame 5. The stuff
bearing 1 inserted into the center hole 10 shown in FIG. 6, It is a busbaker. The semicircular arc
shaped light metal plate 6 'is attached to the outer periphery of the lower end of the cylindrical
body 2, and the direction of attachment of the fc% non-permanent speaker is such that the
semicircular arc shaped light metal plate 6' is positioned on the upper surface of the lower end
outer periphery of the cylindrical body 24 .
In case of placing this Bath Spirit Power - in the vicinity of the small motion speaker of the
speaker box, it resonates with the air vibration generated in the driving speaker and shoots the
protein plate 8 of the flat plate type passive diaphragm speaker , A vibro or semicircular arcshaped light metal plate 6 'or a bearing ball 11 on the inner wall of the center hole 1 O of the
stroke bearing to correct the stroke position of the cylinder 2 and prevent the inclination of the
diaphragm 3 Improvement of speaker improvement has great practical value.
