main emphasis on the sound conversion rate and the matching of the vibration plate and air is on
the effect of sound on the sound waves due to the shape of the F-n inner wall, which has a
serious relationship with sound quality. I was not interested. If this point is explained in the

S. Nag Og A's horn I is a horn that fulfills all the requirements of the 'exponential horn'. The
conventional nail-on nails are not so extreme, but they have the same tendency of tendency
except for circular and positive d-shaped cross sections. Round and square + ji-n have no
drawbacks due to their own reasons, but they are inferior in sound diffusion and directivity,
resulting in medium 11 intense beak-4f. <The cedar horn is an intermediate horn between the
round and square horns and the lower horn. EndPage: 1 Radial (radial) horns have a tendency to
spread and have directivity, and tend to be used for 2 years and 4 years. A radiation horn is
illustrated by a diagram. FIG. 3 is a standard of the radiation horn of an ant scale, and the width /
4 at each measurement point of this horn is a line (3) of one chart (1). The large reason that the
line (3) is formed shows an unequal magnitude of 1 squeezing pressure at each h measurement
point below P2 except for the valley type which shows pressurization from the upper and lower
surfaces in P /. This limits the improvement of the diffusivity and directivity, which is the
purpose of the radiation type horn, and results in the generation of acoustic disturbance.
Further, in the cross-sectional view of FIG. 3 (b), the distance between the upper surface wall (3)
and the lower surface wall (a) between P?-p and 2 + I is gradually narrowed. (The direction of
the side wall (corner than the horn center first) (The direction of the side wall) The purpose of
the strong mlJ-like sound wave diffusion, but the side pressure from the previous one's +
111111a 41) limits the effect to seven. Deterioration of sound and vibration due to forced
diffusion is recognized. This clear-cut is done to remove the entry point of the horn, and each
curved surface of the horn does not disturb the flow of the sound wave and increase the
diffusivity to the salt point by not applying unequal pressure. This is a rectangular horn for the
purpose of improving directivity, improving resolution, and improving sound quality, which will
be described with reference to FIG. 17 and the embodiment of FIG. 2 and Table 1 of FIG. In the
horn of FIG. 17, assuming that the long side is the width and the short side is the height, width /
height (assuming this is Rn), Rn is mourning (1) (i). Let ? of Rn of each measurement point form
an arithmetic progression which increases sequentially from the throat (2) of the horn and let the
increase rate be d, and n be the measurement point number--n-a-1-1 (N? /) d... (Formula /) can
be expressed. Substituting a = /, ?, d = ? 6 into this equation gives (a) of Table (1), and a line (1)
of Table (1) with a graph. As a result of actual injection & = /, j7, ?2 ? d ? ?j7, if tL <, and d is
smaller than ??, the diffusivity and directivity deteriorate. ???? ?????? The distance
between the top wall (3) F and the wall (g) thicker than 7 impairs the narrow sound quality, but
the horn throat (, 2) ly? If the surface is circular, or if I ? in the sound path keeps changing until
it becomes a square near P?, a = / ? / a = 01. Use it until /. Rn at each measurement point of
the horn in FIG. n-/ Rn = a + (n-/) d + bc (c n /, 6> 0) и и и-and--------- ing. If this equation V?a = /

@ (2, 2) in 1A (1). Wholesale at point P / Tho is smaller, and the cross section of the horn's throat
(2) is b = 0 at b = 0 in (? ?)) and exclusively according to (b) (form /) (m /) v ' i can be included
in i). The horn in FIG. 17 is a straight line in @ (1) of Table A (1), and indicates that each surface
of the horn is sound and straight and there is no unequal pressure difference.
The horn in Fig. 2 is the line (2) in the diagram (/), and the 7 @@ shows the spreading of the area
of the horn horn and the pressure from the upper and lower surfaces of the sheep's horn too,
showing the spreading of sound wave diffusion. Follow Apart from the four disadvantages
mentioned above, the disadvantages of the conventional horn can be ruled out. Also, it can be
recognized that the horn of the octograph has 'Qtl' in diffusivity and directivity as compared to
the horn in FIG. In addition to these, as a reference example, as a result of carrying out a horn
having each flare of a double a-line, a parabola ? circle and an ellipse, it turned out that it has
each feature. In the implementation of the straw horn, it is possible to obtain the best result by
selecting an equation that forms a flare that conforms to the difference in the conditions for
expanding the horn cross section and substituting the optimal number. In Fig. 17 to Fig. 3, since
it is customary to spread the vicinity of the opening and measure the diffusion of sound in this
way for the production of each side (b), an enlarged state of the vicinity of the opening is shown.
