BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a cross-sectional view of a conventional ion
speaker. FIG. 2 is a cross-sectional view of the ion speaker according to the present invention.
FIG. 3 is a perspective view of another embodiment according to the present invention. Figure 175-6-7735 (2) Figure 5 correction Figure 5-Figure 2 Figure 2 Figure 3 Figure 3 is corrected as
follows. FIG. 76-
The present invention relates to the structure of an iono-speaker, and further, is characterized in
that the gas to be ionized is enclosed in the inside of the diaphragm, and the onon odor which is
a drawback of the ion-speaker. In order to prevent this, FIG. 1 shows the structure of a
conventional ion speaker. With the electrode (1) provided at the center of the cylindrical
insulator (5). The high electric charge 1-E is totally applied between the electrode (1) and the
annular electrode (2) arranged at a small distance by a direct current high-electrostatic discharge
# (4) to ionize air between the two electrodes. Further, by superimposing an AC signal by the
signal # (5) through the transformer <6) on this DC high voltage, the ionized air is excited by
exciting the ionized air by the horn (7). It emits sound by the This type of speaker has an
advantage of being able to perform sound reproduction well up to extremely high frequencies
because the vibration system mass is zero as compared to the generally widely used
electrodynamic speaker and the like. However, on the other hand, since ionized air generates
ions, it has a disadvantage that it suffers from onion odor in use. Furthermore, the conditions of
excitation are affected by the weather conditions such as the humidity of the air to be ionized,
and there is a drawback that the operation start is not constant. The present invention provides
an ion speaker in which the above-mentioned conventional drawbacks are eliminated, and it will
be described from FIG. 2 that (1) is an electrode and is provided at the center of a cylindrical
insulator (3). Is an annular electrode disposed outside the insulator, and a high voltage is applied
between the electrode (1) and the annular electrode (2) by a DC high voltage power supply (4).
(5) is a signal source, and the signal voltage is superimposed on the DC high voltage through the
transformers (2) and (6). (7)はホーンである。 The above construction is identical to the
construction according to FIG. 1, but differs from FIG. 1 in FIG. 2 in that the ionization region (8)
between the electrode (1) and the annular electrode (2) is enclosed. Like the diaphragm (9) there
are six points. In the above-described structure, the processes until gas ionization and ion
excitation are the same as in FIG. 1 except that l) oscillates at the point where the ionized gas
totally oscillates. こ。 Therefore, although the condition that the vibration system mass which is
the most characteristic of the ion speaker becomes zero is considered, the above-mentioned
diaphragm (9) is extremely thin and lightweight polymer resin (for example, polyamide resin,
phenol tree W1. Polyester resin etc.) Sound of the audio frequency band by selecting one thin

7あ、。 l Fig. 6 shows another embodiment of the present invention and shows an ion speaker
comprising insulators + s +, (d and electrodes 11 <+ facing the center of these insulators, (2))
facing each other with an interval of 2 (7) is a diaphragm provided in a cylindrical shape so as to
surround the above-mentioned insulating outer peripheral edge and seal the ionization region
(8). In the present invention, as described above, since the gas to be ionized is sealed inside the
diaphragm, since the ionized gas is not directly bound to the atmosphere, 1 ozone odor can not
be transmitted, and it is sealed. Since the conditions of other gases do not need to be affected by
atmospheric humidity etc., stable operation can be obtained at all times. Fist Explanation FIG. 1 is
a cross-sectional view of a conventional ion speaker. FIG. 2 is a cross-sectional view of the ion
speaker according to the present invention. FIG. 3 is a perspective view of another embodiment
according to the present invention. Utility model registration applicant 7 曾 ス ク ス ッ ク ス 株
