Abstract
Ultrasound oscillators emit ultrasonic waves. An ultrasonic driving part drives the ultrasound oscillators such that the ultrasonic waves propagates in a first direction D1 from one side toward the other side and propagates in a second direction D2 opposite to the first direction D1 in a structure S. The ultrasonic driving part drives the ultrasound oscillators by changing frequencies of the ultrasound oscillators such that a current value flowing through the ultrasound oscillators is a maximal current value.
