Detailed Description of the Invention The present invention improves the means of support and
the O4 yore with regard to six transformers? 9 transformers have been put to practical use using
conventional electrets, lN "", A- / edge. This transducer is constructed, for example, as shown in
FIG. 1, and can be used as a speaker or a microphone. That is, 11.12 is the 11th fixed electrode,
and a large number of through holes X are provided, and the 1% second fixed electrode 11.12 #
'i faces each other. In each case, a film according to 17 ░ 13 ░ 14 is provided. This first one.
The vibrating membrane 15 is disposed in parallel between the second fixed electrodes 11.22.
The vibrating film 15 is previously provided by being stretched on one surface of the metal
support frame 16. When the diaphragm 15 is disposed between one fixed electrode J 7 ░ 12 as
shown in FIG. When the vibrating membrane 15 is disposed between the fixed pole 11 and 12, a
ring as a spacer on the other side, that is, the side opposite to the support frame 161111 Spacer
17 is provided. A conventional transducer is constructed as described above, and when a signal is
applied between the imaging film 15 and, for example, the fixed electrode 12, the diaphragm
vibrates and can be used as a speaker, and conversely, the diaphragm 15 is used. When vibrated
by sound waves, the diaphragm 11 and the fixed electrode 7? , And can be used as a microphone
by converting as a change in capacitance of JJR +. However, according to the above conventional
transducer, the distance between the vibrating membrane 15 and the fixed electrode is different
from the distance m between the vibrating membrane 15 and the fixed electrode. In the case
where the directional characteristics are 80-character characteristics that are symmetrical in the
directions of 0 ░ and 180 ░, the above-mentioned conventional transducers make each of the
devices electrically external. Lead wires were connected to the '11' poles of the pigeons to be led
out and drawn out to the outside. It is not good in terms of performance to draw a long lead wire
which is extremely complicated, such as a combination of soldering of a lead and a case, etc. The
present invention has been made in view of the above-mentioned circumstances, and in addition
to improving the directivity characteristics, a transducer .lamda. Embodiments of the present
invention will now be described in detail with reference to FIGS. 2 to 4 which is intended to be
provided. That is, in FIG. 2, it is a cylindrical case made of an insulating material having elasticity
of 19 degrees.
The external shape of the case 19 is as shown in FIG. 8 in the case of a person, for example, and
the both collar portions in the axial direction are appropriately bent toward the central direction!
L piece 19 turtle s19 moth is formed. An inner case 20 is disposed immediately inside the case
19. The inner case 20 is also made of an insulating material, but is sufficiently harder than the
outer case 19. Further, the inner diameter of the inner case 20 and the inner shape of the outer
case 19 are set so as to match the outer diameter and @ 4. An engagement means is provided
which doubles as a part and restricts displacement in the rotational direction. That is, this
engagement means is a cylinder of the outer case. -From the wall part of the concave part
notched into a notched part 19 $ and a convex part 20 'integrally formed so as to project on the
outer circumference of the cylindrical wall of the inner case 200 so as to coincide with the cutout
1jI @ This convex part 20 snow has a groove 20. at its center. The inner case 20 also has a
cylindrical shape, and a locking piece fill bent in the central axis direction at one edge in the axial
direction. A ring-shaped spacer 21 is fitted in the inner case 2 # as shown in FIG. 2 so that the
first fixed electrode is overlapped with the spacer 21 as shown in FIG. The first fixed electrode U
has an outer diameter that matches the inner diameter of the inner case 20. Then, a large
number of through holes Y are provided, and the electret 22. Is provided in the form of a film.
The fixed electrode U has its electret surface side directed upward. Then, the ring-shaped spacer
23 as described above is further fitted thereon. 7). J Next, a vibrating film 24 is disposed so as to
be superimposed on the space 2 J. Since the vibration film 24 is provided in advance in the ringshaped support frame 25 so as to be stretched, it is fitted together with the support frame 25.
The outer diameter of the support frame 25 is also the same as that of the above-described
spanners 21 and 23, but as shown in FIG. A protrusion 25m which is led out of the case via a
portion is integrally formed on a part of the outer periphery thereof. Next, a second electrode is
fitted so as to be superimposed on the support frame 25. The second fixed electrode is also
provided with an electret 36m on the surface on the moving film 24 side and a large number of
through holes Y. The fixed electrode of @ 2 is distributed as shown in FIG. If so, the electret 26.
The side surface is inserted into the support frame 25 so as to approach the photographing
motion and smell 24, and a stepped portion 26 is formed in the thickness T direction of the fixed
electrode e. The fixed electrode has a small diameter portion and a large diameter portion in the
thickness T direction, and the small diameter portion is included in the supporting frame 25 so
as to bring the electret 261 closer to the vibrating film 24. be able to. Next, on the upper surface
of the second fixed electrode 26, a spacer 27 similar to the above spacer 23 is superimposed.
Then, the inner case 2o and the measurement electrode and the like housed in the case 20 are
collectively housed in the outer case 19 as a unit 0 in this case, the locking pieces 19t, 19 of the
outer case 19 . However, the above-described internal case 2o and spacer 27 etc. are pressed and
held together. As shown in FIG. 4, the terminal 28.29 is provided at each of the fixed electrode
ridges and the lead edge 1 with respect to one unit sized as described above. The fixed electrode
weir. It is arranged so as to be pressed against one side in a vertical direction with respect to the
bridge, and is fixed to the ship-like support base 30.31 by screws 32.33 and the like. Therefore,
the terminals 211 and 29 can determine the degree of snow and support the unit. Support M and
Y 28.29, unity and y. As shown in @ 4 (b) and (Q) K, the method for bonding varnish f is as
follows. May be formed on the locking piece 191. Furthermore, as shown in FIG. 1114 (a) as a
terminal, a folding piece 36 ░ that can be folded into the locking piece 1fh of the case and a
lead-out portion 36t that extends the terminal 36 in the perpendicular direction are integrally
formed. In the case of using this terminal, use the terminal as shown in FIG. 4 (и), and long-extend
the projection 25 of the support frame 25 of the diaphragm 25 and the diaphragm as shown in
FIG. Then, as shown in FIG. 4 (f), in the present invention, the printed board 38 is provided with
the opening SSl and the assembly SS is easy. Frontage 38. And the pressing pieces 311. , 3g, unit
