Fluid ejector including mems composite transducer

An inkjet printhead comprising:

• a fluid ejector comprising:
• a substrate, first portions of the substrate defining an outer boundary of a cavity and second portions of the substrate defining a fluidic feed;
• a MEMS transducing member, a first portion of the MEMS transducing member being anchored to the substrate, a second portion of the MEMS transducing member extending over at least a portion of the cavity, the second portion of the MEMS transducing member being free to move relative to the cavity;
• a compliant membrane positioned in contact with the MEMS transducing member, a first portion of the compliant membrane covering the MEMS transducing member, and a second portion of the compliant membrane being anchored to the substrate;
• partitioning walls defining a chamber that is fluidically connected to the fluidic feed, wherein at least the second portion of the MEMS transducing member is enclosed within the chamber;
• and
• a nozzle disposed proximate to the second portion of the MEMS transducing member and distal to the fluidic feed;
• a mounting member comprising an ink passageway, the ink passageway being fluidically connected to the fluidic feed;
• and
• a sealing member configured to seal around the fluidic feed and the ink passageway.

An inkjet printer comprising:
