ABSTRACT:
An ultrasonic liquid ejecting apparatus for discharging liquid droplets comprises a housing including a chamber for holding liquid therein having an intake port connected to a liquid supply container. A bimorph vibrator system is provided comprising a vibrating member secured to the housing in pressure transmitting relation with the liquid in the chamber and a piezoelectric transducer secured to the vibrating member for inducing a displacement therein to discharge a small quantity of liquid through an nozzle opening formed in the vibrating member. A circuit is provided for exciting the transducer at a frequency corresponding to the resonant frequency of the vibrator system.
