For example, as shown in FIG. 6, in an ultrasonic generator in which a large number of ultrasonic transducers 1 are arranged concentrically at equal intervals on a solid plate 3, a focal point 11 is set on the central axis of the plate 3. In order to form this, it is necessary to sequentially increase the delay amount of the drive signal applied to each ultrasonic vibrator 1 as the ultrasonic vibrator approaches the central axis of the flat plate 3 in the radial direction.

That is, since each ultrasonic transducer is oriented to an initial focal point in advance, the phase of the signal that drives the ultrasonic transducer is adjusted to 5! Even if the focal point is formed at a new position by adjusting the height, the sound pressure in the main lobe of each ultrasonic transducer will be concentrated at that focal point. Compared to an ultrasonic treatment device equipped with a vibrator that can change the focal position, it is possible to control the focal position extremely efficiently.
