DETAILED DESCRIPTION OF THE INVENTION In the present invention, the example JL uses an

membrane 20 into the space. The back surface fixed electrode base SI is disposed at the edge of
the back surface group IIIIl constant electrode array, and a back surface volume 6 close to fL @

electrostatic speaker. Rounding K makes the air gap 4.4 ′ of the first-listed speaker very small
(about o, og− 彌 ˜0.3 m / IIN) Or, the speaker unit itself has to increase the volume of the
moving system to increase the volume velocity. The pigeon which has made the air gap 4.4 ′
smaller, vibration I! It is impossible to take a large vibration amplitude of 2, and as a result of the

Even when the sound pressure improvement is achieved, the% is too hot (1 to 1 and therefore the
number of fluids that start to deteriorate is reduced). As described above, the speaker for
warning the pressure drop improves the sound pressure for 1 h and the hand N also causes
deterioration of the directivity characteristics (1? However, at the expense of directivity
characteristics, the air gap 14.4 'is made smaller, the vibration system area is heated up, and the
sound pressure on the front axis is increased to make it IA-shaped! It can be said that the sound
pressure on the frontal axis has been increased using h ゐ, that is, sharp directional
characteristics. By attaching the horn to the electrostatic type speaker K, the radiation resistance
by the horn can be extremely effectively increased, and the control mode can be made resistance
control. In contrast to the electrodynamic type speaker, the vibration type system is extremely
large (20 to 3 o) and therefore it is an electrostatic type large constriction. The sound power
characteristics are output by the resistance 餉 1lllvc f and the f, and the sound to which the
sound power characteristics are to be distributed is output. However, although the horn O
radiation resistance is greatly required <Sic <th <and (when the horn o @ e effect is large heat (if
the effect is increased), the resistance control area company is expanded, but the on-axis sound

1111! In the conventional structure, the problem is Y-Ikh. 8 ', i6 °. The present invention is a
defect of the above-mentioned conventional O electrostatic layer horn speaker, tampering with
the finger characteristics and the on-axis sound pressure characteristics, the horn and Speaker
unit vlll N! The purpose is to smooth out the islets, and a plurality of chopsticks speaker units
should be arranged side by side with each other in a suitable angle summer tube 4 in accordance
with the design purpose of each unit. It is a combination of multi-cellular horns with throats of
different aperture ratios. The following is an example of the + X idea: c @ X @ + 0 in FIG. 2 which
will be described together with FIG. 3) IK 3111) 101.102 ri electrostatic lid speaker unit, these

is a mounting plate for attaching the horn to a speaker box or the like, and can be understood
from ζO take ( ( パ パ
■ speaker output is the first m G speaker airt). It is
necessary to make the arrangement angle f11 freely even if the two O-speaker units 101 and
102 are extremely close to + Cm because spring can be extremely thin (eight or less can be
divided by light). Absent.
* When connecting a horn to the electrostatic layer speaker, it is not desirable to squeeze the
horn like a dynamic 1g horn speaker from the sound pressure sensitivity 0 point, and therefore,
the throat product of the horn will become large. It is effective to make the speaker unit thinner.
Because the area of the electrodynamic horn speaker is small, the angle θ (ao0 or more) is set to
4 as in the case of the horn and the speaker unit egaw because the area is small! It is extremely li
to sum up! ilImである。 That is because the electrodynamic speaker unit is large. Taking
advantage of the feature of thinning of the electrostatic 1 speaker, one horn gives a large number
of throat fins, and couples the speaker unit to the waist W of it. In the case of K1 or 彎 softly the
horn is different from tffc. It is possible to make a circle by selecting the arrangement angle of t,

the directivity characteristic is also a storm (not at B 'and at a frequency K which is not the case).
The characteristics A and B of the present invention can flatten the on-axis sound pressure
characteristics as desired, and the directivity is also greatly altered compared to the prior art. A
'is a 300 direction sound pressure characteristic of the speaker of the present invention, B is an
on-axis 00 sound pressure characteristic of the conventional example, and B' is a 300 direction
sound IF1 of the conventional example.
As described above, when combining the tm speaker unit and the horn as described above, a
plurality of lids are used in the mouth electrostatic lid horn speaker to make the most of the thin
features of the electrostatic type Sbi-Kaet, The speaker units are arranged in close proximity to
the angle of 4 It 1, and each speaker unit has a horns fight--even one-even one! According to the
present invention, according to the present invention, it is possible to obtain the following effects:
