[Description of the invention] Description of the invention Name of the invention Loudspeaker
speaker 2 The scope of the present invention required range In order to focus the magnetic flux
on the opposite surface of the magnetic pole, an iron plate for magnetic pole and an annular ring
for magnetic pole A magnetic circuit having an iron plate, and a movement plate in which a spiral
continuous coil portion is formed by a conductor welded or attached on at least one side, and the
iron movement plate generates a magnetic flux generated in the magnetic path A speaker for
roaring sound, characterized in that the central part and the peripheral part are close to the
magnetic circuit so as to be substantially parallel and close to a @. a home page system relates to
a speaker for bird sound for reproducing a signal of 8 Kdx to 50 KHz 48-35342-02 O band
among the reproduced horsepower number band. In order to reproduce the 8 KHz-50 KH x O
ultra high frequency band, it is necessary to make the mass of the vibration system extremely
light and to make the rigidity of the drive mechanism, the diaphragm and the OIl body extremely
steep. Therefore, in the conventional general structure, reproduction of the above-mentioned
super-high frequency band is impossible. As a special example, there is a ribbon speaker having a
drive mechanism and a diaphragm formed in the same direction. However, since the structure of
this ribbon speaker is the same as the diaphragm and the drive wire ring, the electric impedance
is small at a very low level, generally 1 O -1,-, S). A meeting with a width of 11 KII requires a
transformer for impedance matching. For this reason, it is easy to use 48-35342-03 as a
combination of food sheet / soil 0j11 wave resistance 4 I 惟 O, and to flatten the frequency

characteristics of the matching transformer in the target band, Production is difficult because of
the need for special techniques for linear velocity, and it has the disadvantage of high cost. Since
the present invention was made by focusing on point 0, the purpose of the present invention is
an audio frequency band that easily combines the electrical impedance of the speaker and the
output impedance of the amplifier. It is an object of the present invention to provide a speaker
for high-pitched sound which has no influence on the nature of the reproduction. Another object
of the present invention is that it is possible to manufacture p1 inexpensively by being able to
regulate the electrical impedance of the t speaker and the output impedance of the amplifier
without using a combined F lance and sj 48-3834-2 04 A speaker for high-pitched sound that
can be easily blessed. Next, the system 1 embodiment of the present invention will be described
with reference to w & 1111 (1). A horn formed with l (1a), (2) is a fixed equalizer located at the
center of ho y (1) O, and a trapezoidal O-concave (S) is formed at the center of its lower surface It
is done.

center and a channel is formed for the formation of a 9 channel. Daughter Magnets) <5) and

generated magnetic fluxes do not mutually cancel each other and serve as a 1lll voice coil. Note
that iIl, i! In the figure, the diaphragm (8) is shown in which the peripheral portion and the

same as that of the first embodiment and the procedure a, and ma, but in the present
embodiment, the iron plate for magnetic pole (2) (4) is fixed at the top 111c of the pole # 4 &,
and a tapered portion (2 &) is formed opposite to the taber 5 (41) of the pole-like iron song (6)
for the magnetic pole, That is, the only difference is that they are formed upward. This pigeon

Occurs.
Then, a coil 5 (9a) (10s) formed in this magnetic flux and [the vibration I [俤] in the father's form
is allocated, so that a voltage is applied between the coils s (9'1 (loa1) to flow a current). For
example, the coil (kl (10a) K flux acts effectively to cause the vibration of the 1Illl plate (8) to
make a rectangular shape with the magnetic flux, ie, vibrate vertically in FIG. 1.2, thus the tone
(1) In the above, the coil fi11 (9 畠) (10 ml is shown on the both sides of the diaphragm (8) (O
both sides are shown), but the one provided with a piece Tl1 KO In this case, the force F for
driving the diaphragm −) is F = BJI (B is the magnetic flux density, J is the length of the pile O, I
is the current fL flowing through the coil). As shown in the example, install coil II (9m) (10a) on
both sides if the conductor O length is longer. An advantageous obtained by increasing the force
F, also is also O correspondingly becomes possible to reduce the magnetic flux density B. In the
present 'J # proposal, the coil section is integrally formed with the diaphragm as described
above, which can ignore the compliance between the coil section and the diaphragm and has an
effect of increasing O to the high frequency band of the reproduction band, Magnetic coils IIC) A
