present invention is a substantially flat% A used for sound IIl converter! l Although it relates to
the improvement of the moving plate, and more specifically, the tL ? diaphragm mainly used for
the so-called one flat loudspeaker 1, the improvement of the present invention is such an
expansion IILtI! ! The same applies to microphones that can be used. The idea of the present
invention is that it is sounded with fLt ? a substantially flat-shaped loudspeaker aK, and ms
made of eg polystyrene and polyfrethane, preferably a strong stiffness V @ made by expansion
bonding of granules. It can be used for the hole line cotton-like plastic l1OIIL-like lf'L. For
example, the field to which the present invention is applied is the field of application of the
present invention in the field to which the present invention is applied. Other known devices are
described in the introductory part of the patent application not including 1, so the introductory
part is a book "::::: 2: 2 :: A1111111 [K dll, 86] vibration There is a band that transmits the air,
said band being enclosed by a vibration absorbing device, generally a vibration damping

The vibration is transmitted to the above-mentioned vibration damping peripheral portion when
the vibration damping horse weaving portion of the 'Kanji's @ already has the same de-sticted
plate portion NO-1it- In the case of S spoofing, its f ? LK x /) tends to reduce the acoustic
sensitivity lK directly somewhat. The purpose of the present invention is O, in which vibration is
transmitted to the peripheral portion of the vibration damping as much as possible. Such purpose
is achieved by the isolation 6 strict or vibration transmission at the peripheral portion of the
vibration damping at-the end of the cast to form an endless mirror on the peripheral portion,
which is subjected to many tests. c4all niece. This is described in the Japanese Patent Application
for the Application of the Invention w 'g, f L' t 'l /%, b (in which the moving vibration is the abovementioned groove cut n 7) J peripheral edge It is due to the fact that the vibration 7MO shape is
stopped to change in the same part as entering. Another object of the present invention is to use
such an improved diaphragm when it is used for a flat loudspeaker I! For example, the singlet or
ta of the diaphragm may be added directly to the signal source 5 in response to the reproduction
of a certain tone 1w note such as a high note 5 and n at least one sound reproduction pan is
provided in the vibration transmission band. If this idea is in the group of loudspeakers and in
each group of loudspeakers, various vibrations l! If it is applied to a band that emphasizes k, f ?
L; b, it is possible to achieve very unique sound effects advantageous to the stereo sound

assembly connected to the electromagnetic assembly can be recommended to be partially piped,
and the material at the connection point with the conductor can be prematurely damaged. Avoid
the bl vs OS split groove members, the back of the plate 1 and the electromagnetic pair! In order

to facilitate the understanding of the present invention, which is provided in the body and 4D)
one narrow band, one specific implementation thereof will now be described with reference to
the attached FIG. As can be seen from the ono of the attached drawing, the vibration plate 1 has a
flat front w 12 and a vibration substantially surrounding a specially shaped special portion 4
similar to a human O wing, as can be seen from the ono of the attached drawing. It has a back
surface t that defines a damped peripheral portion S. The thickness of the specially shaped
portion adjacent to at least the vibration damping peripheral portion 3 is smaller than the
thickness of the peripheral portion 8 and a side wall portion 5 is formed between the two.
Endless groove members connect the profiled portion to the side wall portion 5 to define a
sudden change of direction and to increase the damping or isolation feature with respect to the
vibrations intended to enter the vibration damping peripheral portion 3 And reduce the vibration
transmission feature.
Such vibrations are generated, for example, in the electromagnetic assembly 7 and this
electromagnetic 111X body is not vibration 1 [1 is not as a loudspeaker! If you use it as an
electronic phone, you get a vibration concentration 7 nta p. Since such an electromagnetic aix
body 7 does not fall within the scope of the present invention, it is merely a sign shown by the
arrow / II KI III, and an arrow port is an arbitrary link connecting the electromagnetic assembly 7
and the specially shaped portion 4. A device of the type A is shown schematically, said specially
shaped portion 4 preferably being outside the geometric center of the recess 4 for this
connection purpose. If, for example, the diaphragm should also have a device for emphasizing
certain tones, such as high heights, then the specially shaped part 4 may have endless groove
members 6 and Between the grooves 17t, which has a straight groove 17t, which connects the
recess 9 with the endless groove member 6. The groove 17 has a bottom wall 17 '. A metal band
8, for example an aluminum foil, connects the recess 9 to the perimeter 14 of the specially
shaped part ridge, ie to the endless groove member 6. Conveniently, the metal band -8 is the
bottom wall 17 'of the groove 17. ':: 2 :: ? 2 * m * t * n * to 9, 6 ░, 7 pairs of conductors 10 and
11 are provided. The conductors 10 and 11 are formed on the specially shaped portion 4 (pegs
that end in the mist 9 and are respectively recommended in the miso member 11.130).
Therefore, the conductor a @ jXl / ? @ AF11 & 11 KIRIJJ, "1--v1--Rt--eC1 11-, no-Krwzva Next to
the endless groove member, it is necessary to describe several kinds of endless groove members.
It can have a shape and it is important that the side wall portion 5 define a sudden change of
direction in the turbidity 12114 of the specially shaped portion 4, for example, in the
electromagnetic cylinder 7. It is to avoid the vibration continuing to move to the vibration
damping peripheral part 3. The advantage is that the ridge of groove member 6 is on the front! It
is close to. In the embodiment of FIG. 2, the channel 6 is substantially KV-shaped. In FIG. 3, the
miso member 6 has a polygonal cross section so that several sudden changes in direction are
achieved by means of f'LK. In this embodiment, the formed lid has a retractable sUa material so
that it can be made into a diaphragm 1 'tube, and it will not be rt # i. In the fourth example
embodiment IIIl, the vibration 1 [11 defines seven letters 1f and 1 'almost at right angles. Metal

fortunate to be clean.
When one symbol 7 vibrates at a frequency corresponding to the length of band-8, the signal
generated in the same electromagnetic assembly is directly transmitted to pan r1 at the cO signal
