ABSTRACT:
A liquid spraying device including an elongate first vessel closed at one of its ends by a first free face of a piezoelectric transducer capable of emitting waves into a liquid filling the vessel, and open at its end remote from the piezoelectric transducer. The piezoelectric transducer includes a second free face opposite its first free face, and wherein an elongate second vessel is disposed symmetrically to the first vessel relative to the piezoelectric transducer, the second vessel being closed at one of its ends by said second free face of the piezoelectric transducer, which is thus also capable of emitting waves into a liquid filling the second vessel, said second vessel being open at its end remote from the piezoelectric transducer.
