barley bowl has a diaphragm plate, such as Ripun slide, fine ll-alt ', duralmin foil, etc. and an Ow
plate as a diaphragm, and the diaphragm is held by the electrode in the up and down direction
Kffll. Then, I wrote a small note on the left and right both sides and gave Il prosperity K11ll with
a fixed magnetic pole. It therefore has various disadvantages. That is, it is large at the 1st K and
the center part of the potter's wheel elillifffi, and small and small at the upper and lower
electrodes. Because of the number 2111L and the diaphragm 1Ihll−, various resonances occur
and the amount is large. The sound pressure body vhKIIIIIl of the II # front plate is received
through the air gap existing in the gap between 餉 JK, the diaphragm and the am on the left and
right sides thereof. The present invention addresses these drawbacks. That is, the first object of
the present invention is to obtain an electronic vibration * such as to make it possible to move
the piston 1 without having the entire diaphragm Iktr. The second object of the present invention
is that the sound pressure before and after the diaphragm is influenced by each other to obtain a
one-to-one type of acoustic conversion. In the following, the present invention will be described

in detail K1m1. Fig. 1 1ck is a diaphragm, which is a thin plate of aluminum, Jura, Min, etc., and
as shown in Fig. 2, many e! ! It has a convexity. In the embodiment, it is possible to obtain a
strength such that the vibration fno can vibrate the piston, or a trve shape, so that each convex is
formed. Necessary company that is not necessarily continuous. 2 is an edge portion provided on
the outer periphery of the diaphragm 1, and has a corrugated shape as shown in FIG. A magnetic
pole 3 is provided on the left and right sides of the vibration plate 1 'for applying a magnetic
field to the vibration plate 1. It is an insulating member in which the four company manufactured
111f7 and the magnetic pole 3 are continuous. The electrodes are sanded electrodes # 111 on
the upper and lower sides of the 111111 plate 1, and exchange current with the diaphragm 1
through the knee edge s2.
For example, in the case of using the microphone as a microphone, when sand is received from
the diaphragm 1 pressure, 1 is integrally coupled with the paper surface of FIG. したがってl!
An electromotive force is generated due to the vibration of the magnetic pole 2 and the vibration
of the magnetic field 2 diaphragm 1 of 3 and k, and the electricity m flows in the vertical
direction on the surface of the diaphragm IKF1 to obtain an output from the electricity @ 5,5. As
described above, according to the present invention, the diaphragm is very thin and is very ugly.
In order to move, if the distortion is directivity without a small amount of t3, one acoustic
conversion S is obtained. Also, since the edge portion is provided, the sound pressure
interference of the j1 ml plate is eliminated, and a device with high sound pressure sensitivity
can be obtained.
