Beschreibung
Zusammenfassung:	An acoustic-wave generating device includes a drive circuit and a power auxiliary circuit. The drive circuit includes a capacitor chargeable via a direct-current power supply, and a drive switch to cause power to be supplied from the capacitor to an acoustic-wave source which produces heat through energization to generate acoustic waves. The power auxiliary circuit is operable to supplies power to the drive circuit to avoid a decrease of power supplied to the acoustic-wave source in an operation of generating a series of acoustic waves from the acoustic-wave source through switching of the drive switch.
