| Abstract(in English) | The author is studying an ultrasonic source that integrates each element of an aerial high-intensity ultrasonic source, namely, a horn, a resonance rod for longitudinal vibration, and transverse vibrating plates. In this paper, to form the more powerful aerial standing wave sound field, simulation analysis using the finite element method was performed so that the distance between the vibrating plates would be one wavelength of sound waves in the air. Next, an actual ultrasonic wave source was manufactured, and its electrical characteristics, vibration characteristics, and sound pressure distribution characteristics were measured. The ultrasonic source formed a powerful standing wave sound field in the air, even though the total length was half the wavelength of the longitudinal vibration. For an input electric power of 10 W, a high sound pressure in the standing wave sound field of about 6 kPa was obtained (sound pressure level of about 169 dB). |
