Ink jet print head acoustic filters

摘要

The ink jet print head defines a plurality of operating plates (136,152) held together in a superimposed relationship forming an ink jet print head defining a plurality of ink manifolds (160), ink inlets (102), ink drop-forming orifices (108) and a plurality of acoustic filters (254,260). The acoustic filters are a plurality of compliant areas connected by an acoustic filter constriction (272) aperture and a plurality of separate compliant areas all connected to ink manifolds for suppressing unwanted frequencies during print modes.
