Claim 15:
16. A fluid ejecting device, the device comprising,
a housing configured to receive the fluid to be ejected;
a flexible aperture disposed on the housing and a pin fixed to the housing, the flexible aperture being deformable to define i) a closed configuration such that the aperture receives at least a portion of the pin, and ii) an open configuration where the pin is disengaged from the aperture; and
an actuator connected to the housing and configured to induce vibrations to the housing to generate fluid momentum in the fluid contained within the housing such that the fluid i) elastically deforms the flexible aperture to the open configuration such that the pin disengages from the flexible aperture and fluid flows through the aperture.
