DETAILED DESCRIPTION OF THE INVENTION This invention relates to the fluidization of all S
class signals, in particular pronounced words. The source of 1 *, body) number amplification by
power jet 4-! The reason is that it is known per se, which is a book originally produced by two
poles and different techniques. One of them uses a constant flow jet and adopts Hm of jet
deflection. French patent? The method described in lp, 1, 531, 690 is famous. The other
technology is that the power of the jet is variable, and there is a conventional siren as an
example, but in this siren, the flow section of the flow is changed by the adapter Shiiko It is
customary that the above-mentioned flow changes take place in a discontinuous manner between
the extremes and minima. Although the technique # of the straw 211 class # has produced the
pulse streaks of which the power e level of the sound which is the output to date is I20,000 Wat
IC [L 7] so large) and is comparable to each other, The functions of these two techniques are very
different in the operating frequency nodal voice. S of the siren that has been known since ancient
times? However, the book can not achieve even the upper limit Fi 500 Hz of this frequency
range, so the inertia is increased due to such restrictions, and also the force · · · · · · "hato-"
residual noise is large, it is inevitable for the fluid current method- It is. Such a system to which
the above-mentioned technique is applied is # 'i unsuitable for a pneumatic lightning
loudspeaker. Because two Nematic fist loudspeakers are first of all, their poor frequency range
should span the spectrum of the words to be pronounced, ie 300 Hz to 3000 Hz, and secondly
transmitted This is because it is required that the S / N ratio, which reflects the clearness of the
signal and the Fi openability, must not be smaller than 10 dB over the entire range of this
operation 7 range. This invention implements the method described in the above-mentioned
patent F in a complex manner, in particular a generalization of the method for generating the
sound wave, especially for the transmission of the governmental business by voice, and on the
other side. To provide a noise generator. The sound generator described in French Patent No.
1,531, 690 can achieve a complete jet deflection Il # l] by a slight shift of the movable deflection
element, thus low inertia It has the advantage of This occurrence @ as a loudspeaker 6 1?
Fearing is made possible by incorporating an amplifier 111 circuit which excites the transducer
coils based on signals from the electronic transformers and microphones or sources.
According to a first embodiment of the invention, amplification of such signals is carried out by
means of an "n" stage connection, in which stage the movable elements of the first stage Fif
converter and the pressure are The interaction between the fluid flow and the subsequent series
of steps consists of the conventional fluid amplification working by either jet deflection or jet
tension principle. It is preferable that tK # i and the generation of compression residue be
achieved by a turbo jet type device, which reduces the size of the device to obtain extremely high
power. According to an embodiment of the '# J2 type of this invention, the pneumatic
amplification means is the result of the simultaneous action of a series of identical sirens
delivered by a common turbojet generator. . In a preferred form of embodiment of the invention,
the loudspeaker which has been Pled in the range of = 7-utility model registration-is a shop-book
for the partial change of the power flow. The type of variation used here is one with low inertia
and high fiml amplitude, ie allowing one re-transmission at the same time with a high signal to
noise ratio with a faithfulness of the speech spread It is a thing. The current of the flow, in this
invention, the transmission of the sound waves to the surrounding media-through the conduit of
I-this flow, which consists of the flow f with respect to the average flow it-is a pneumatic onepass and transformation A single stage li characterized in that the vessel and it is sectioned by
one wall it! r It is something that is called bamboo. That is, a pneumatic circuit is provided, which
is extended by the diffusion means at the wall of the wall, the diffusion itself being extended by
the flJ scientific horn-and also of the wall of this wall On the other side, the converter shall have
its anvil, element, one annular ring, jl xt niji, and this pottery body protruding from the wall of Ek
into the plane of the throat of an annular ring 8-le This movable obstacle is F 41 on top by a
continuous elastic link! It is connected to the. In addition, the wall may be provided with holes,
which allow free flow of fresh air induced by the fluid flow side to the surface of the wall
(thereby a release effect) ), So that efficient cooling of the coil takes place naturally allowing the
heated gas to be used as a primary fluid. The reliability of the coil derived from the fact that the
salani, the coil and the conductive element for excitation thereof are completely insulated, and
the coil / the circuit connection method for reducing the stress due to the number of coils to the
minimum. To about this coil can be compared to a high degree of amplitude.
Another small percentage of power and light loudspeakers can require only a small 11, river
pneumatic hoar that can easily be generated by a compact contained source of compressed air,
so Loudspeaker can be made portable and loses in doors 9-11! にある。 At the respective side of
the wall 1 will be given a clear understanding of the three unconstrained, exemplary
implementation W of the invention described in the following with reference to the attached
drawings. The completed t-biaxial circuit 2 and the T converter 6 are shown. The two-nematic 10
□ path 2 squeezes the nozzle 4 extended by the horn 5. Diffusion 11 having a cross-sectional
shape Together with i6, the nozzle 4 defines an annular conduit 7, the four tubes passing
through the throat 8 and 2, in its plane, the annular obstruction 9! ! 111 are being scolded.
Upstream of the throat 8 there is provided a circular manifold 10, which is formed with a
uniform row of holes 12 on the base to be fed from the chamber 11 V can be fed from the
introduction pipe 16. The 0J mist barrier body 9 is connected to @ 1 via a continuous elastic link
22 made of an elastomer, and this wall 1 has an outer ring 24 and an inner 11 ring 26.
According to the conventional embodiment, the converter 6 includes a permanent magnet 14
which makes the annular air cap 16 1 & 1 and an electromagnetic coil 17 is provided in the
longitudinal direction in the lO-1-1.d + 1 air gear knob. The coil has a winding 1118 connected to
a terminal 19, which is raised to apply an electrical signal through the 2 # i blade 21. This
electrical signal is either microphone 56 or Chi 7 recorder 577! But it is converted into a signal
by the conversion of the input voice signal 55, which is also beaten by amplification in the
amplifier 58 provided in the latter stage). Applied. The whole converter is triggered 7? An
opening 26 may be provided in the cylindrical case 25 to provide an opening 26 for suctioning
the nine warts 27. The Kononema Nanok ラ ウ ド loudspeaker works in the manner described in
pJF. Correspondence to the signal flowing through the coil 18 The obstacle 9 is to move in the
plane of the throat 8 to modulate the power flow section based on the decoy value corresponding
to the average flow rate, and the pre-evening flow rate with the throat 8 in the absence of a
signal. (The width of the signal to be determined by the position of the obstacle 9 and determined
to be transmitted is changed by the fluctuation of the straw flow because of L4. is there.
This driving fluid 9 at the surface of the wall 1 generates a considerable flow tube of the induced
air in the wall 1 on which the transducer 6 is located. FIG. 2 shows the% characteristics of the
invention, in particular including the downstream part of the channel of the induced air 27, the
channel with the air cap 16 of the wedge-shaped stone being extended first. A coil 17 is movably
mounted within the air cap, after which the passage is bifurcated therefrom. Holes 29 equally
formed along the edge of coil 17 to simultaneously equalize the pressure on both sides of the
coal wall allow 9 air to flow freely inside and out of this coil. This induced stream 27 passes
through the holes 60 formed equally along the edge of the self-contained j-ring 24 of the wall 1
'Ik! It originates from the iIi controller 6 and merges with the driving air flow at one stroke of the
throat 8. Accurate positioning of the coils 12-17 in the fIi-shaped air cap 16 of the magnet 14 is
preferably performed by a rod with 24 m positioning. One of them is disposed in the center 61 of
the inner 1111 ring 24 and the other, i.e. 62, is provided on the outer ring 26 and these outer
and inner rings 26 and 24 are ring-shaped b66 and #r It is attached to the fixed integral 15 by
the diffusion means 6 which has the following cross-sectional shape. With further reference to
FIG. 2b, the movable obstacle 9 is provided with a recess for winding the winding 18 and a
winding end is formed at its gating end, this winding is excited by the elastic blade 21 [41]. And
one of the ends of these blades 21 # i is soldered to the final winding 64 of this winding & 18.
The flade 21 is disposed in the coil 17 and embedded in the housing and embedded in the
annular seal 22, and each of the other ridges is connected to the signal input terminal 19 for
excitation in the following manner: The blade 21 is connected to the terminal 19 in such a way
that it does not come into contact with the metallurgical component of the converter 6 during
production 1 and that the stress applied to the soldering is reduced to a minimum stratification
of 13-fields. Preferably. The six pneumatic loudspeakers delivered with respect to FIG. 1 and FIG.
2 provide outstanding flight. That is, when the pneumatic-power pair acoustic ratio can reach 15
× in the subsonic zone, the efficiency of the S / N ratio of 25 dB is achieved at 4. For a generator
with an effective generator pressure of 1.5 bar, a mass flow rate of 6097 s, and an electrical
power of white noise and about 150 watts, such loudspeakers are C) giving a power of 300
wattage w / t, where the S / N ratio is approximately 20 dB, the efficiency in this case is about
8%, and the induced air flow rate is almost 10 r / s.
Furthermore, if all other conditions are equal, the power of the blue tatami changes
approximately linearly with both the power and the pneumatic power. The fluid amplifier shown
in Fig. 3A in Section 3 is a noise generator of power i! It is something to be done. The generator
comprises a turbopode 14-return nib L et 65 having a single flow filter 6 from which a secondary
flow is taken and fed to a cascaded fluid amplifier. The first uptake 67 takes place upstream of
the burnout 68 and this uptake is fed to the annular conduit 69 # 1. The output flllK of the
conduit 69 is controlled by the transducer 6 in which the annular obstacle 9 is arranged and
excited by the input signal. For a particular position of the obstruction 9 at the output Ill of the
annular groove 969, the jet of fluid drawn in this way is collected in the chamber 40 and from
there it advances into the air along the arrow 41. For another position of the obstruction 9 at the
output 111 of the conduit 69, this jet enters the 4W 42, which conduit elevates the hole 46 in
the second. This second power flow is uniformly taken from the main flow 66 and delivered from
the intake conduit 45 to the annular groove '144. At output @ 46 of annular conduit 44, the
second power flow described above is alternately deflected into conduits 46 and 47. Conduit 46
discharges the jet into the air along arrow 48, while conduit 47 passes control hole (fluid signal)
through hole 4915-- "main fi 36? To discharge. Depending on whether a fluid signal is present,
this mainstream is an exhaust channel! It escapes through conduit 51 through 50 or cascaded
vanes 52. The implementation shown in FIG. 4M is a schematic illustration of a group 56 of five
identical sound generators 59, which may ring a single amplification stage, with these generators
Fi tubes 54. It is fed from a common turbojet 65 via the manifold made. The acoustic power of
such equipment is the result of the individual acoustic power of each generator, and the overall
efficiency is equal to the efficiency of each individual generator # 1.
