BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a structural explanatory view showing an
embodiment of an electrostatic transducer according to the present invention, and FIG. 2 is an
output characteristic curve diagram for explaining the operation of FIG. 1, FIG. FIG. 4 is a
configuration explanatory view of the main part of another different embodiment. 11 иии и и и и и и и и и

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electrostatic
transducer particularly suitable for electret condensers. In the past, electret condenser cartridges
made of electrostatic charge type sensors have been in practical use, but in this case, m have
remained unresolved in terms of various characteristics and constructional aspects. That is, there
is a tendency that the amount of charging between the electrodes is insufficient or not 4.5) -111.
"It was not necessarily recognized as good in terms of friend S / N%. Moreover, although the
change of the output by the movement of a town movement pole was comparatively large, it
could not be posed as a problem of this W type. Furthermore, K requires a phase correction 10
circuit and! There is a drawback that the circuit configuration is complicated by requiring a
manual amplification circuit to handle No. 1 as Tsushdell. Therefore, this invention is made in
view of the above points, and it is an object of the present invention to provide a very good 1
excellent electrostatic transducer that can easily and surely remove the problems and drawbacks
of the above-mentioned tanks. It is. Hereinafter, an embodiment of the present invention will be
described in detail with reference to the drawings. That is, as shown in FIG. 1, for example, with
respect to a bifurcated pole 11 having a cross-sectional wedge shape movably supported on the
cantilever 10 as a cartritz, it faces each face of the coughable pole 11 and The fixed poles 121 to
124 formed of the first to a4 flat 4 L-shaped electric treads are disposed in the lower part in a
square V-shaped lower part. Here, the fixed poles 121 to 124 formed of the first to fourth flat
plate-like electrets are formed to have a pair l'51 face which is sufficiently larger than each
surface of the movable pole 11 and the right side shown in the drawing The second and third

electret fixed poles 122.123 which are attached to the positive electrode (+) and the left side VC
shown in the figure are the first and fourth electret fixed 1fj 121 ░ 124 and the other pole (-)
Let's assume that the book is being imprisoned. The electrostatic transducer constructed as
described above is used, for example, as an electrostatic capacitor cartridge, and in this case, EO
<connected f shown in the same figure. That is, oTwJ and others 11 are grounded, and the first
and third electret fixed poles JffiJ, JZJ are commonly connected to the R channel FIT transistor +
ma13, and the second and fourth electret fixed poles 1 x 2.124 Commonly to the L channel -j, the
FET transistor non-junction circuit J41C is connected to 1110 + 1 L ? ?-Next, the operation will
be described. As shown in FIG. One electret fixed pole 121 or 122 located at tn co-A has an
output characteristic indicated by a curve #A and an output ? indicated by a curve B with an
electret solid 'l Ц pole 123 or 124 of another force In this case, the output timing shown by curve
C, which is a combination of these curves A and B, is Lw for each common pair. Only and it
serves as a R-channel -? output characteristics.
By this action, it is ensured that the change of the output is reduced with respect to the
movement of the movable electrode 11, and this n is the change curve of the music 1M1Af or B
corresponding to the conventional output time. This is clear when comparing with the changing
range of the curve C which is the physical properties of the projecting blade according to the
present invention, which is synthesized from these, and the reduction gjJ effect is remarkable. In
addition, all channels are connected to each other in a differential manner, and all pairs of
electret fixed poles 121 and 123 or 122 and 124 are covered in common, and -f: n? One piece,
7: 4t и C, sufficiently thicker than each opposing face of pole 11! Opposite! Since i [l is formed 1,
1 and so on, it is ensured that the charge capacity between each electrode is increased to
contribute to the improvement of the S / N characteristic by 7 r, and the phase correction circuit
And differential amplification for densification-there is an advantage that one path may be
essentially eliminated. In the third embodiment, as another embodiment, one electret counter
arrangement 321 to 324 is planarly arranged in the form of a letter, and these are arranged in
the same manner as the seven cantilever n-cantilever 39. It shows the case where it faces the
three town reed pole pieces 31) -314. As an example of the same width as FIG. 4, two OT
reference pole pieces 41J and 412 identical to the cantilever 40 are sandwiched by two electrets
swaying drops 421.423 or 422.424 facing each other. If you say like wearing! It shows the case
of one arranged in a straight line. Also in the case of FIGS. 3 and 4, it is possible to achieve the
same function and effect as in the case of the chopstick example, and since it can be described
according to @V, details will be omitted. ?????? According to this invention, the fixed pole
of a predetermined number of logarithms is used as a pair of fixed poles of the second type,
which are polarized to different polarities with respect to the movable pole. It is possible to
simplify the conventional deficiency and provide a very good Sakai-shi type transformer nousa
that can be surely removed. Needless to say, the present invention is not limited to the
embodiment described above and shown in the drawings, and various modifications can be made
without departing from the scope of the present invention.
