DESCRIPTION JPS5298436
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a schematic view of a conventional flat plate
type electro-acoustic transducer, and FIG. 2 is a cross-sectional view showing an embodiment of
the flat plate type electro-acoustic transducer according to the present invention. It is a side view.

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a flat plate-todevice converter, and more particularly to an improvement of its diaphragm. Recently, the entire
vibrating surface can be uniformly driven as compared with the conventional electro-acoustic
transducer, so that a speaker, headphone, microphone made of a flat plate shape that can be
regenerated by ideal perfect piston vibration. , Etc. That is, this flat head cedar electric-speaker
converter has a predetermined polarity between a pair of magnets II, 12 as shown in FIG. S э L

metal foil 132 equipped with a swing! It is the one that casts motion control. While the magnetic
field like the broken line illustrated by e & ? ? 1 stone 11.12 is beasting, by making the current

conventional flat-plate wL air-neck 4 is made of aluminum as a gold leaf foil in its staring and
tearing, and this is coated on a film base, the whole film 1 It is said that the uniform
omnidirectional movement of the yarn plate tends to be inhibited as a result of unevenness on
the surface and non-uniform thickness due to the presence and absence of the metal foil. It had a
drawback. Therefore, the present invention has been made in view of the above points, and is an
extremely good flat plate electro-acoustic system comprising a diaphragm improved to simply
and surely remove the above-mentioned conventional defects. The purpose is to break the
converter. An embodiment of the present invention will be described in the following with

reference to the drawings. That is, as shown in FIG. 2, it has the property of location, and is kept
between the nine pairs of magnets 11.22 on a vibrator base such as a synthetic resin film 231
etc., uniformly using a semiconductor material layer 232 such as germanium or silicon. The
thickness is coated, and in the semiconductor material layer 232, for example, quadruple
material 233 such as acinogen is wave numbered by electric or mechanical means so as to
partially form a predetermined conductive pattern. Thus, the diaphragm U formed to have a
uniform thickness as a whole is disposed. Since the flat speaker thus configured in this way has
its JtR function & L1 formed as a whole in a uniform thickness, that is, in terms of strength, it is
as shown by the broken line by the magnet 21.22. The vibration based on the acting force given
by flowing an electric current such as a voice signal to the electric material 233 having a
predetermined conductive pattern in a stable magnetic field is uniformly driven as a whole of the
peristaltic plate 23 Consequences are those that become mouth oil.
In the above description, the vibration plate is made of a synthetic resin film as a base and Jdending a conductive material such as aluminum to a uniform thickness, and a portion thereof is
mechanically machined or the like. 1 'insulation-"the conductive pattern of the F9T bond is
formed by' 2 [i] It is superior to form a uniform thickness as a whole even if it is cut, the point is
that the moving body base upper opening conductive layer and Substantial v

in the range of-well, not insisting on the other hundred in this series. Therefore, as detailed
above, according to the present invention, it is possible to suppress undesirable fractional
vibration to the mouth's fishing by diving completely without a whole (9) weir as a whole, and
furthermore, it is shown to Oo Since the assembly and handling can be simplified, the cost can be
reduced and FC can be improved to improve the cost, and it is possible to use a diaphragm that
can be removed easily and reliably with the conventional defect: r5. A flat plate electro-acoustic
transducer can be provided.
