    摘要： An inkjet ejector has been developed that enables the ejector to be operated at a frequency greater than 80 kHz. The inkjet ejector includes a body layer in which a pressure chamber is configured with an outlet having a volume that is less than a predetermined volumetric threshold, a flexible diaphragm plate disposed on the pressure chamber to form a wall of the pressure chamber, a piezoelectric transducer having a bottom surface attached to the diaphragm plate, and an inlet layer in which an inlet channel is configured to connect the pressure chamber to a source of liquid ink, a cross-sectional area of the inlet channel at the pressure chamber divided by a length of the inlet channel being greater than a predetermined linear threshold.

    摘要： A printer fluid dispensing subassembly has a fluid dispensing body having at least one transducer and at least one ink channel, and a compliant polymer aperture film having an array of apertures to direct fluid toward a substrate, the polymer aperture film bonded to the fluid dispensing body as an external layer of the fluid dispensing body, the polymer aperture film arranged to form a wall of a manifold in the fluid dispensing body and to attenuate acoustic energy. A printer fluid dispensing subassembly has a compliant polymer aperture film having an array of apertures to allow fluid to exit the fluid dispensing subassembly, and a fluid dispensing body bonded to a back surface of the polymer aperture film such that the polymer aperture film forms a wall of a fluid manifold, the film being arranged such that a side of the polymer opposite the fluid dispensing body is air. A printer has an ink supply, and a printhead to receive fluid from the ink supply and form images on a substrate by selectively actuating an array of transducers in a fluid dispensing subassembly, the fluid dispensing subassembly including a compliant polymer aperture film having apertures through which fluid is forced in response to the actuating of the transducers, the polymer aperture film arranged to attenuate acoustic energy from the actuating of the transducers.
