ABSTRACT:
An ultrasonic vibrating device for atomizing a liquid by acoustic vibrations generated using a vibrating plate mounted to a piezoelectric vibrator. The piezoelectric vibrator consists of a piezoelectric ceramic and a pair of electrodes positioned thereon and on both end surfaces perpendicular to the thickness direction of the piezoelectric ceramic. The vibrating plate is provided with a lot of holes, the area of each hole opening on a top surface being different from the area of its other opening. The piezoelectric vibrator being efficiently vibrated in response to an alternating current voltage, whose frequency is almost matched to the resonance frequency of the piezoelectric vibrator. This vibration is transmitted to the vibrating plate causing the vibrating plate to also vibrate. A liquid introduced to the vibrating plate is effectively atomized by way of the vibrating plate and the holes thereon.
