DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an ultrasonic
wave moving apparatus suitably used for a transducer or ultrasonic cleaner used in air or water.
A thick disk or cylinder having a diameter-to-thickness ratio of 1: 0.2 to 1.4 is used as the
vibration radiator 1, and an arbitrary surface of the radiator 1, for example, the upper end
surface 1a is a Langevin type vibrator or the like. Ultrasonic transducer 2 directly or integrally
via vibration transmitting rod 3 having half-wavelength integral multiple length 1-A +. In the
ultrasonic vibration apparatus of the conventional structure shown in FIG. 1 which is coupled,
when the ultrasonic vibrator 3 is excited by the oscillator 4, it vibrates from the vibrating
radiator 1 and emits omnidirectional waves from all outer surfaces. To present or aim. Depending
on the application, it may again be possible to use only ultrasound emitted from the surface 1 of
the vibrating radiator, for example the lower end 1b or the side IC. In such a case, it should be
used as a sound wave emitting surface of the imaging radiator (ultrasonic waves are emitted
wastefully from the outer surface excluding the lower end surface 1 b or the side surface IC).
There was a drawback that the sound loss was not reduced. The proposal is used as the sound
emitting surface of the imaging radiator. . The above-mentioned conventional defects are
eliminated by covering the wrinkles on the outer surface of the surface other than the mold
surface via the acoustic wave reflecting air gap layer. That is, as shown in FIG. 12, when using the
lower end surface 1b of the vibration radiator 1 as the sound wave emitting surface, the sound
waves are respectively applied to the outer surface excluding the radiation surface 1b, ie, the
upper end surface 1a and the side surface 1c of the imaging radiator. Reflective gap layer 6a.
Recesses 1, 1 and 1 / (for forming 6C (/ are cut to form an annular cover integral 5a and a

cylindrical cover integral 52-C from above from above) Bound to Further, as shown in FIG. 3,
when the side surface IC of the vibration radiator 1 is used as a sound wave radiation surface, the
cover integrals 5a and 5C may be attached to the upper end surface 1a and the lower end
surface 1b of the vibration radiator, respectively. . In addition, the sound wave emitting surface of
the vibration radiator is removed (the sound wave reflection void layer formed between the outer
surface and the cover covering the outer surface blocks the radiation of ultrasonic waves
generated on the outer surface of the radiator). In the embodiment of FIG. 2, the air gaps 1i 5a
and 5C are formed by cutting the recesses 81a 'and IC' on the outer surface of the vibration
radiator, but as shown in FIG. The void layers 6a and 6b can also be formed by cutting off the
concave grooves 5a '55bI. As described above, since the present invention is the one in which the
cover is integrated with the sound wave emitting surface of the vibrating radiator via the sound
wave reflecting air gap layer on the 58th surface, the ultrasonic radiation from the unfertile door
surface of the vibrating radiator The acoustic loss is small fA <fJ, and it is effective to be able to
emit high-power ultrasonic waves from any sound wave emitting surface.
