Support plate.
[Detailed description of the invention] In this article, the sound wave is generated by flowing one
stream of voice to a whistling whistle disposed in the Buddha's kingdom. Is related to the
improvement of There are known conversion devices for electric sound =, for example, those
commonly used in so-called bail type speakers shown in FIG. In this Awa-to-Speech converter,
four permanent magnets 1 and 2. 3 are radially disposed, and a curved magnetic field in the
direction of the arrow is formed at the central portion. At the center jltll of valley wax, pole pieces
5.6 and 7.8 are attached for forming a magnetic path, and at the other pole are attached pole
pieces 9 and 1 o for stocking a valley magnet. A storage place is formed in the dark of the pole
pieces 5 and 6 and the pole pieces 7 and 8, respectively, and in this space, each end of the pick
ring 11 in the form of a film is inserted like gM, It is fixed by a support 12.13 and a nonwrinkling material holder 14.15. As shown in FIG. 2, a ribbon-like four-pole body 16 is deposited
or attached to the diaphragm 11 as shown in FIG. 2. Arrows f in the magnetic field H shown in
FIGS. : When the voice current flows in the direction of DI, the handle plate 11 contracts in the
direction of the arrow pjF in the direction of the arrow S. This acoustic wave is mainly

propagated outward from the central portion of the diaphragm 11, as is apparent from FIG. As
shown in the upper half of the figure, the Bail system's swaying sound R converter has the
stylized characteristic that the frequency characteristics become flat because the ribbon-like
conductor 16 and the diaphragm 11 follow one another and move along. , Driving all over: @ S:
has a good feeling that the characteristics are good and efficient. However, since the central part
FiMi pole piece N of the peristaltic plate 11 does not face each other, it is only intended to be
excited by one leakage flux, so the efficiency of the central part is particularly reduced and the
total number of magnetic fluxes of permanent magnets Even if there are many problems, the
efficiency is scary, and because the permanent magnets are arranged radially, there was a
hundred defects when the shape became dog-like. The present invention improves the efficiency
by arranging the relationship between the bellows-like sliding plate and the drive magnet and the
magnetic circuit configuration of the drive magnet, thereby improving the efficiency and making
it an assembly and assembly wheel. An apparatus is provided. FIG. 3 shows (3) an embodiment of
the sound writing apparatus according to the present invention. In the figure, a bellows-like #
plate is a plate with two valleys (30a) and two peaks f30b alternately for performing constant
stretching vibration. Both ends of the diaphragm (3) are fixed by a foot member 1311 to 1311,
and as shown in FIG.
Conductors consisting of @ 5 tas body parts (32a) (32b) and (32C), these conductor parts (32a)
(32b) and (32c) are approximately the flat grew side surface (30c) of a swing # I &- It is located
at the center, and the direction of the voice current flowing in this conductor is arranged to flow
in the opposite direction between the adjacent conductor parts, ie, (32a) and (32b) and (32b) and
(32c). Reference numeral ls3 denotes a magnet such as ferrite, which is disposed as shown in
FIG. 3 so as to face the conductor portions (32a) (a2b) and (32C) on both sides of the diaphragm.
That is, on the upper surface of the moving plate-on the lower surface side, on the lower surface
side, the N pole of each magnet (d) is the same as the conductor portions (32a) (32b) and (32c) It
is arranged in parallel to the plate. (4) Note that the dotted arrow direction in the figure indicates
the direction of the magnetic field, and the voice '! [KIIIi is configured to be orthogonal to the
flow direction. ? Is a connecting portion made of a magnetic material, for holding the magnets
on the upper and lower sides of the moving plate ? in parallel and for connecting magnetically,
and on the upper (2) side, between the magnets In the N pole or -10,000 lower surface +1111, S
* between the magnets are connected respectively. 3 [9 is an air flow hole formed in the
connection portion (b), provided for suction and emission of air generated by suction and
generation of air generated by expansion and contraction movement of the busy plate ? It is a
thing. 13Iri supporting plate supports the fixing member t311 @ 11 so that the conductor
portions (32a, 32b, 32c) are positioned approximately in the middle between the plurality of
magnets arranged on both sides of the vibration & (d) It is fixed to both ends Fi connected part
(goods). The support plate may also be formed of a magnetic material. FIG. 4 is a partial plan
view of FIG. 3 (9), in which the same reference numerals indicate the same knots. When the
conductor 1 (5) in FIG. 3 or the conductor (a2 a) shown in FIG. The conductor part (32a) (32a)

(here, the conductor part (32c) flows from this side to the other side of the paper web and it
becomes the point-arrow direction of the direction riaa of the magnetic field). 32b) (32c) receive
a force F in the direction of the solid thick arrow in FIG. Accordingly, since the conductor
portions (32a) and (32b) H are attracted to each other, the air in the half portion of the facing
image @ plate mountain is compressed and radiated to the outside through the air flow holes
(solar).
Also, the conductor portion (32b) (! l: (32c) move away, and draw air into the flat part of shooting
& (7). Thus, when an audio current is supplied to the conductor, the diaphragm-stretches and
vibrates according to the audio current. The oscillating air flow generated by this transmission is
radiated to the outside through the flow holes. In addition, as shown in FIG. 5, it is shown in FIG.
5 whether or not one silk conductor has been disposed one by one in the flat ridge portion of the
silk wound plate on both sides of one more lamella in silk 3. For example, the diaphragms (3ua)
and (30b, (6)) are configured in 2IIl #, and for example, three conductor portions (32ai) and
(32a2) for the inner surface of these diaphragms, respectively, (32a3) (32bl) (32b2) (32b3)
(32cl) (32c2) (32c3) may be disposed. Further, FIG. 6 shows another embodiment according to
the present invention, which is a combination of only a plurality of voice-note devices shown in
FIG. To explain in detail, an acoustic device having a configuration as shown in FIG. 3 (in FIG. 6
(a), it is indicated by-enlightenment. 2), the magnetic poles of the magnet are arranged so as to
be reverse to the direction of the magnetic field in the valley acoustic device. That is, the magnets
provided at each sound writing frame and the bowl, for example, (40a), (41a), f40d) and (41a '),
are closely packed in the connecting portion 43 so that the magnetic poles are reversed. And, as
shown in FIG. 6 (a), the bellows-like imaging plate (44+) is formed so as to be able to vibrate as
shown in FIG. 6 (a) through the interval portion-provided on the support plate + 40B (41A) and
(41B). Each sound V device ? and emotion etc. 1 'J: Connection member-is integrally configured.
My father, Fig. 6 (b) is a connection diagram showing the connection of the conductor parts (46a)
(46b) and (47a) (47b) provided on the bellows-like moving plate 1 (No. 1 (7)) is there. In the
same figure, for example, the voice current derived from the voice amplifier portion causes the
lead portion 19 + f-a to flow through the conductor portion 446a) (46b) in the direction of the
arrow n1. It is intercepted to flow in the direction of the arrow. Therefore, the voice current or
the conductor part (46a) (46b) and f47a) (47b)! When flowing in the direction of the arrow of 6
[1 fb], the force F in the direction of the arrow in FIG. 6 (a) is received, so the bellows-like
diaphragms provided in each air-saving acoustic transducer ? and 141 are compressed together
The air of the facing transmission surface is radiated to the outside through the air gap. As
explained above, the present invention is the adjacent snakes I1 of the diaphragm!
?? lllllIII], and it is located in the central part of the diaphragm as in the prior art because it is a
kind of signal line that interrogates N ? and S ? for a plurality of conductors flowing in
opposite directions. Since the valley (8) conductor is excited by the hollow conductor instead of

exciting the conductor by the ratio lc leakage flux, the imaging plate can be uniformly excited
over the entire area, and the efficiency can be increased. Furthermore, in the present invention,
on the other side 1 of the moving plate, the magnetic conductor different from -111i in the other
of the above-mentioned vibrating plate is respectively opposed to the conductor in the same or
chronic chronicity. The arrangement of the agile magnets in such a way as to face each other, as
well as the configuration of the book that magnetically couples all other magnetic mutual 1-ii1 of
these magnets, so that the magnetic circuit can be configured simply and rationally, It has the
advantages of being able to simplify assembly and manufacture and of further strengthening the
nest, and the like. @ 4 Brief Description of Figure (2) Fig. 1 is applicable to conventional bail
