Patent attributes
A manifold component for a droplet ejection head, the manifold component comprising: a mount for receiving an actuator component that provides one or more rows of fluid chambers, each chamber being provided with a respective at least one actuating element and a respective at least one nozzle, the at least one actuating element for each chamber being actuable to eject a droplet of fluid in an ejection direction through the corresponding at least one nozzle, each row extending in a row direction; a manifold chamber, which extends from a first end to a second end, and widens from said first end to said second end, the second end providing fluidic connection, in parallel, to at least a group of chambers within said one or more rows and being located adjacent said mount; and at least one port, each port opening into the manifold chamber at the first end thereof; wherein at least one portion between the first end and second end of the manifold chamber is shaped as a hyperbolic acoustic horn.
