Transverse vibrating plate ultrasonic vibration source integrated with horn

Abstract

This paper describes the development of a compact ultrasonic vibration source that has a transverse vibrating plate that can achieve large displacement amplitudes. An ultrasonic vibration source was designed, in which the ultrasonic vibrator excluding the transducer was approximately the same length as the transducer (half the wavelength of the longitudinal vibration). Therefore, the ultrasonic vibrator was integrated with the transverse vibrating plate and the amplitude expansion horn. The design method for integrating the ultrasonic vibration source was clarified, and the vibration characteristics of the vibration source were investigated. The ultrasonic source was used to atomize droplets, demonstrating its practical utility.
