DETAILED DESCRIPTION OF THE INVENTION The present invention is a plate drive type
electrokinetic electroacoustic transducer 40 which does not require a matching transformer.
First, the conventional 011f) IIIl IEIl electroacoustic integrator will be described with reference to
FIG. 1 and FIG. Fig. 1, 21! In l, 1 is a CQ-shaped ring, and a stone monument 2 is attached to this
O-ring 1. $ A is a stone 24D top surface with a center boa, 4.4 and 6.5 respectively the abovementioned caustic 10s vs. gangster Ik, what a sec ond magnetic pole,. The magnetic poles 4, 4
and 6, 6 and the magnetic poles 6,... 'And 6, 6-have polarity oa * isi air-eaves 4-e.g. The reference
numeral 7 denotes a diaphragm, and the 01 m working plate ? is held by the magnetic poles
4.4, S, S, 6 and 6 above. The rectangular spiral #O conductor 9 is printed on the insulator film on
the ?O diaphragm 7 To! Because the square spiral part of this rectangular spiral O conductor is
arranged in each of the above-mentioned monumental air spaces, 4! 010, 10.11 11 11 Fi above
the sulfur @ t! The frame 12, 12 is an insulating film which is acidified on the side of the printed
insulating film and O conductor, and the insulating film 12.12 includes a conductor e and The
frames 10 and 11 are electrically isolated. 1s, 1sri and above * 1: 41 rL non-nasal light board on
the side of the above-mentioned 1 Be done. 14, 14 are leads l? ? e apl co O lead 14, 14 ? ?

signal current is passed to the conductor [stock] via the lead wires 14, 14, the non-working board
located in the magnetic sky moves in a horizontal direction KIl, which is O. However, the abovementioned conventional electrokinetic electroacoustic transducer has the following
disadvantages. 1i11 pole 4, 8. ??????????????????? Due to the resonance of
the air layer in the 2 o recessed part of the drawing of the damaged board 7, so-called front car
effect, the sheet is wrinkled in the high region and in the fk area the recessed part 0 air becomes
the added mass and the sound pressure At the same time, the sound pressure frequency
characteristics become uneven. 2 Lead wire 14, 14 Vr take-out must be soldered through S * St
hole 18.16 opened at the corner of Krt @ 16 ░. At that time, solder or contact with magnetic
pole 6.6 easy.
Also, it is difficult to position the magnetic poles 4, 6... And the conductor S on the surface
printed with the conductor of the vibration end printed on the printed surface. It is necessary to
reduce the size of the 4 C, O Tatami 110 rtlt @ Ii4, @ Cabinet and 1141 g, Seki O width, or-East
WtO maximum summer heat-Install a conductor near the nose pole It can not be done and the
efficiency is lower. The present invention cancels the front room effect in the above-mentioned
conventional example, and a sound pressure horseshoe II! It is a simple structure that provides
an electrodynamic electro-acoustic transducer made by self-electrostatic transducer which has a
simple structure and lly property becomes flat, and with the addition of a reed agate. To explain
along with msml + 49th example m. Note that the same numbers as in FIG. 1 and FIG. 1 in FIG. 4
and in FIG. 4 attach the same numbers to the aw and 411 Kk E (16, 1 '7 tim-/ 1 end face attached

nonmagnetic material, and OI! The tumbling furnace 7-Gou's previous work and tl ?-4 was made

with an insulation film thickness of IJ65 $ L and a thickness of 10 ?m or less was applied as an
M-1 conductor 9 to a thickness of about 10 ?m. The sound pressure frequency characteristics
become very flat in the frequency band of 2 KHs to 1.0 KHs as a result of the diaphragm plate 7
of warmth being driven on the entire surface substantially in one plane with the baffle baffle
drawing. As is apparent from Dan 9 @ 6 e 4 A, B, according to the present invention 1, the
conventional example AO @ pole 4. II, 1B and 4. The t7 frame 10.11 and the insulator 12, 12 are
not required, and the structure is simple, and the assembly becomes very heavy. According to the
present invention, according to the present invention, the soldering between the lead 1II 4.14
and the conductor 9 becomes an island, and it has a corner point at which the conductor 9 and
the sheet at t 6.17 ░ / n also disappear In the above embodiment, the magnetic field 71 and the
magnetic pole 71. 1 / h is a separate body from 7/7, and it is good because it is possible to
combine the blasp and the pole. In the present invention 0 electrokinetic electroacoustic
transducer is constructed as described above 61. According to Home III, the following effects can
be obtained as well: fL h 40 'e & h. ) Acupuncture ? ? ? (1) The front room effect is ? ? ? w

setting up is easy. (@ The lead of the conductor and the diaphragm and the soldering of O are
harmful birds, and the conductor, 111 and O sheet can stand still. 4, lIwLD111 single description
