DETAILED DESCRIPTION OF THE INVENTION This invention relates to an improvement in the
method of supporting the S @ section of a flat loudspeaker. [I mean, this device is desired as a
speaker 7L Vibration direction of the main moving body (a drive coil / generated by direct
current to the door @ 1 perpendicular direction to the plate surface) shooting (3)]-" It has no
effect at all, and acts as a cap for movement in other directions, and realizes full piston
interlocking of the diaphragm, which is depicted as a child figure when adopting a flat speaker, in
history The diaphragm support of the flexible diaphragm also functions as an edge of a speaker
that absorbs abnormal vibration at the edge of the diaphragm, and any other device for
restraining the vibration of the diaphragm is required. It is intended to realize a speaker that can
not be realized, and from that point on, it is intended to greatly improve the same wave number
characteristic of the speaker. The invention will now be described with respect to the working
sequence shown in the drawings. In the figure, FIG. 7 is a view from the back side, with the
magnetic circuit of the flat speaker removed, viewed from the back, and the comparison is fine
and there are 11111 and cows, for example, foam polystyrene (4) 9 ′ ′ □ Two #j ['; lff19fflt
[Mi / K ゝ "00" "] are fixed to each other, and the drive coil 3 is wound around these winding
frames. In the illustrated embodiment, although two reels are shown, the number of practical
soils may be fixed, and three or more may be cast in parallel. The flexible film piece S is

connected between the photographing motion l and the frame q surrounding the drop lapping
space with respect to this around the single shooting sore l. The flexible membrane piece S is, for
example, a piece of material having its own elasticity, such as a material obtained by applying
sponge-like polyurethane to a cloth-like material by heating and compression. 3 and 6 and then
cut away from this 114 leaving an edge 2g, as shown in FIG. 3 (oblique view) and FIG. 9 (5). The
shape is as shown in 't-N). The flexible film piece S configured in this way is positioned in the gap
between the flutter 4L / and the framer. As the inner edge of this town 11 film piece S is attached
to the outer periphery of the field moving plate l and the outer edge g of the outer wall g of the
town 11 is joined to the inner periphery of the frame by bonding etc. is there. In addition, when
over-inputting, photographing movement; projecting out forward, and deciding that it can not be
restored to its original position, it is determined that Fig. 6 and Fig.・ In the second confession

the flat speaker which is formed in a rectangular shape as shown in the figure, this fitting piece 9
(in the form of an elongated strip-shaped cloth, (6) = 'ul, Jii [cl, 、, -frny v @ shape o In the case of
flat mxe-30 force, they are attached at appropriate intervals to each other, and in this case, these
caulking pieces t are attached with a margin, that is, with a slight slack so as to restrain normal
vibration of the photographing motion 1). is there.
According to this embodiment, when the diaphragm 1 tries to jump out during excessive input,
these contact pieces 9 are pulled and tensioned to prevent further movement of the vibration ii.
According to the support method of the diaphragm / plate by the groove according to the
present invention, the direction O perpendicular to the plane of the diaphragm l mainly caused
by the current VC flowing to the drive coil 3 is not disturbed at all. Or, this is blocked for
movement in the other direction, and it is intended to adopt a flat speaker when the entire
surface (7) of a complete change. A histone movement is realized, and further, according to the
present invention, it is used as a temporary support made of a flexible membrane piece 5 or as
an edge of a speaker that absorbs abnormal vibration of a shooting @ temporary part. Since it
also has a function, the frequency characteristics of the speaker can be greatly improved.
