Abstract: PURPOSE: An inkjet head and a manufacturing method thereof are provided to prevent the vibration of a piezoelectric actuator from being transferred to a reservoir housing. CONSTITUTION: An inkjet head comprises a restrictor, an ink chamber, a head body(110), and piezoelectric actuators. The restrictor is extended from a reservoir for storing ink. The ink chamber stores the ink supplied from the restrictor. The head body comprises nozzles(118) for discharging the ink to outside. The piezoelectric actuators are installed in the head body to be located at both sides of the ink chamber. The piezoelectric actuators transfer vibration to both surface of the head body.

Abstract: PURPOSE: An inkjet head and a manufacturing method thereof are provided to prevent crosstalk since a restrictor for supplying a plurality of connecting paths is installed and thus a pressure wave, which is generated in an ink chamber in vibration of an actuator, is cancelled. CONSTITUTION: An inkjet head comprises a manifold(122), an ink chamber(112) and a restrictor. The manifold stores the ink, which is incoming from the outside. The ink chamber receives the ink from the manifold and externally discharges it through the nozzle. The restrictor is formed in order to connect the manifold to the ink chamber. The restrictor supplies a plurality of connecting paths. The connecting paths are formed in a circle form and to be symmetrically arranged.
