DETAILED DESCRIPTION OF THE INVENTION The present discussion relates to an i-type acoustic
system and an i-type converter for achieving an increase in sound output V. It is composed of a
pair of fixed i-marks and movable 11 & (iQi board), which are installed opposite each other at a
fixed distance from the electrostatic type 1 air sound box like a rarity. Oh, I'm accompliced I
applied between both% pole! In the female covenant Force the turtle and repulsive force to be
applied from one's own, and let the movable tl pole (swing plate) radiate the vibration of the
vibrating one's ji-c sound by the action of suction or repulsion in the direction of the electrode.
ing. By the way, in order to increase the sound output (sound pressure) of the electrostatic type 1
air flow, it is possible to make the distance between the turtles as narrow as possible or to make
the surface frame of the 11 yarns as possible. It can be achieved by making it large. However, in
this case, the method of narrowing the distance between the two 'S poles of the former as much
as possible is that the swing width of No. 1/11 (1kR1, plate) becomes limited and the relation
between the table and the torsion is integrated. As it is, it is not surprising that it is a very
effective method. Therefore, conventionally, the latter method of increasing the area of the
vibration system as much as possible is adopted to increase the acoustic output (f pressure), but
even in the case of this method, i '+ 1 ? of the Th & system There is a problem that the
directionality gets worse significantly if you go over and over. Therefore, as described above, it is
preferable to radiate the culture output in the vibration direction based on the basic Iconfiguration, since there is a constant O rise in that 9) j sound output (sound pressure) 11; It is
strongly hoped that this limit can be overcome and 'sound output' (sound pressure) can be
increased as much as possible. The present invention has been made in view of the above points,
and is an extremely good 3-to-1 electric f * f converter that can increase the sound output as
much as possible without causing any adverse effects. It is assumed that the age of providing.
The following is a detailed description of the present invention with reference to the drawings.
That is, in FIG. 1, 11.12 is a fixed electrode disposed in a foreign country, and 1314 is in contact
with each of the inner and outer poles 11 and 12 for a predetermined period of time with a Ц #.
Yes 4 free pay (1 board). And two pairs of -fi & 11.13 and 12.14 are respectively provided with
the spacer member 16 common to one end, each of the predetermined! confession 1. Oa & 11
poles (elite) z 3.14 are fixed without glazing so as to have a predetermined interval, and the other
ends remaining are movable 11 'of the respective inner bowls! As shown in the drawing, the
spacer 16 is fixed by h ? (1 m + Jk) Js and a pair of hoods 161 which is equal to one side of the
forefoot of the foot 14.
Here, assuming that the one-leg electrodes 11.12 are provided with the electrets l12 and 122 of
the negative electrode charge in the case shown in the respective 11j of the respective back
electrodes JJJ and JJJ on the outside, no source of deviation is used. Although the main points
are shown, the present invention is not limited to this as will be described later. In addition, the
above-mentioned fixation is now 11 ░ 12 and kt & 13 + "are connected in common
corresponding to both ends of the signal source 17. Now, at the first base of the pole where I-J,
14 are connected in common, the movable 113 ░ 14 is negative in the half cycle where the pole
No. 11 is negative.? negative band i electret) 11 j. What is in the condition of regular zone 1 is
canceled by 122 and 1 me both fix 1i '! The air vibration in the direction of the arrow shown by
the co-KW line, which is repelled by tIL 11112, causes air exclusion, that is, t-wave propagation
to the outside from the opening 161 ? provided at the center of the spacer cylinder 16Ill. And,
when the conversion source 17 takes a half year old different from the above, K is opposite to the
lively work provided one, and the movable-pole (swing 1 plate) 13.14 is a fixed electrode 11. The
air vibration in the direction of the arrow indicated by the dashed line drawn together with zxK
and caused thereby causes the air suction, that is, the propagation of the sound wave from the
outside of the rod 161. Here, the island port portion 161 which propagates or radiates the sound
wave in the direction orthogonal to the four vibration directions is to bring about an increase of
the V echo power (accumulated pressure) obtained sufficiently small with respect to the area of
the vibrating thread. Even if the surface of the vibrating yarn is increased as much as possible,
the apparent radiation area of this pair can be made sufficiently small to be determined by the
area of the drow 5161. As in the prior art It is a book that can gain as much as possible
accompaniment output without bringing about the deterioration of directivity and so on. Of
course, the present invention is not limited to only the above-described actual examples, and it is
possible to carry out one type of modification without changing the gist of the present invention.
For example, as shown in FIG. 11182, a fixed electrode 11 '. With regard to 12 ', let the electrets
JJ2' m112 'be different from each other, and make the fixed t & 11' or 11 correspond to the
movable electrode (vibrant 1 soft) 13 'or 14' at both ends of the signal source 11 'respectively. It
may be commonly maintained, and in some cases, the shaker plate may be equipped with an
electret, and in any case, if it is a common electrode or diaphragm provided with no electret. It is
better to use bias tS instead.
Also, as shown in # I8 doctor two pairs of own weight & JJ '. Each end is fixed to 11 and Jj 'and J
/ by a spacer member 16' in substantially the same manner as in one arrangement, and one
other end is inclined and fixed to an end by a member 16 ' Well, in this case it can be of the socalled horn type. Furthermore, as shown in the fourth example, a multiple structure can be made
based on the configuration as shown in FIG. 1 and sharing a part, and in this case, the direction
of the radiation product is alternated as shown. It may be 4 or 1 bl. As described above,
according to the present invention, the output can be increased as much as possible without
causing the evil of the problem, and the town r111 diaphragm is inserted inside. Since this
construction is used, the electret will not come out III particularly when using electrets on either
side of both Im poles, and there is also the advantage that no separate retaining plate is required.
It is possible to provide a simple electric type electric noise converter 1. и и 14 ms description of
