Description 21: ultrasonic horn 41) circular inner opening from the throat to the opening end A
tubular body is connected to the throat of the horn whose diameter gradually expands, and the
proximal end of the tubular body is attached, and the inner peripheral barrel of the middle
portion of the tubular body 7 is inside the throat of the horn Ultrasonic horn provided with a
partition plate having a circular hole having a smaller diameter than the diameter of the bore and
the inner bore of the cylindrical body
72, the claims
118, Detailed Description of the Invention In the conventional ultrasonic horn, as shown in FIG.
1A), the ultrasonic transducer d1 is placed on the throat portion a of the horn O whose internal
diameter gradually increases 71 toward the opening end from the throat portion 1 a. , And with
respect to the central axis e of the horn 0 1. The result of actually measuring the sound pressure
in the direction 1-forming an angle of f degrees at the throat portion a of the ring C is as shown
in Fig. 1 11 1 11 and the sound pressure 9 largely increases as the angle f increases. . The
present invention eliminates the above-mentioned conventional drawbacks as described above,
and the embodiments of the present invention will be described below in terms of physical
aspects-1 A horn whose inner diameter gradually increases from the throat 2 toward the open
end 8 is a cylindrical body whose tip is connected to the throat 2 of the horn 1 and a horn is
formed on the inner peripheral barrel of the middle thereof. A partition plate 6 having a circular
hole 5 whose diameter is smaller than the inner diameter of the throat portion 2 of 1 is provided,
and at the base end of the cylindrical body 4 a piezoelectric crystal piece is suitably attached with
a pair of electrodes. The acoustic transducer 7 is mounted. And, in FIG. 2, the inner diameter of
the tip end side of the partition plate 6 of the cylindrical body 4 is made the same as the inner
diameter of the throat portion 2 of the horn], and the partition plate 6 of the cylindrical body 4 In

this embodiment, the length between 7 is set to 1 of the wavelength of the ultrasonic wave
emitted by the ultrasonic transducer 7 and the inner diameter is set to 2 times the wavelength of
the ultrasonic wave, as shown in FIG. In FIG. 2, the partition plate 6 of the cylindrical body 4 and
the ultrasonic transducer 7 on the open side of the ultrasonic transducer 7 are reduced in
diameter 8I! Let L be the partition & 6II be the enlarged aperture 8bvcL, and the inner aperture
of the reduced aperture 8a be the same as the inner aperture of the throat 2 of the horn 1 the
same EndPage: 1 and its length be emitted by the ultrasonic transducer 7 The ultrasonic
wavelength of 20 wavelengths was reduced to half, and the inner diameter of the enlarged
aperture portion 8b9 was increased to y2 times the wavelength of the ultrasonic waves, and the
length was increased to 8/4 of the wavelength. In the example 1. In FIG. 4, both ends between
the partition plate 6 of the 1WJ-shaped body 4 and the ultrasonic transducer 7 in FIG. 2 are
reduced diameter portions 3a and g'a and the center is enlarged diameter portion 8b. Let the
inner diameter of each of the reduced diameter portions 8 '* 8'a be the same as the inner
diameter of the throat portion 2 of the horn], and their respective lengths are the wavelength of
the ultrasonic wave emitted by the ultrasonic transducer 7 In the embodiment in which the
internal diameter of the enlarged diameter portion 11.8b is x2 times the wavelength of the
ultrasonic wave and the length thereof is 1/4 B. is there. In addition, in the case of FIG. 8 and FIG.
4, in order to make it easy to mold-mold the cylindrical body 12, 4, the cylindrical body or the
cylindrical body piece 4a, 4b is divided into two, and the cylindrical body piece 4a, The
cylindrical body 4 is constituted by connecting 4b to each other.
7.2 The invention is as described above, 41 in FIG. 2, the throat of the horn l with respect to the
central axis 1 & 1 of the horn 1. The result of the sound pressure n in the direction of making an
angle of 0 degrees in the part 2 is as shown in FIG. 5, and when the angle α becomes a
predetermined value or more, the sound pressure H becomes smaller and 1 does not increase or
decrease significantly. In the case of FIG. 8 and FIG. 4, the same result is obtained. As described
above, according to the present invention, the tubular body is connected to the throat portion of
the horn whose circular inner diameter gradually expands from the throat portion toward the
opening end, and the proximal end of the tubular body is attached. It is understood that it is
apparent from the measurement results because the inner peripheral barrel of the middle part of
the rod body is provided with the partition plate having the circular hole whose diameter is
smaller than the inner diameter of the throat of the horn As a result, there is an effect that can
provide an excellent ultrasonic horn with directional characteristics.
4. Brief description of the drawings Fig. 1 k) is a cross-sectional view of a conventional ultrasonic
horn, Fig. 1 is a characteristic diagram of the conventional ultrasonic horn, and Figs. 2 to 4 are
different embodiments of the present invention. FIG. 5 is a characteristic view of the ultrasonic
horn of the present invention. 1 is a horn, 2... A throat portion, 8 is an open end, 4 is an I
cylindrical body, 5 is a circular hole, 6 is a partition plate, and 7 is an ultrasonic vibration mover.
