<p>A print head comprises a pressure chamber in fluid communication with a nozzle and an actuator structure in operative communication with the pressure chamber for generating a pressure wave in the pressure chamber. The actuator structure comprises a membrane, wherein a first surface of the membrane forms a flexible wall of the pressure chamber and a piezo actuator, wherein the piezo actuator is arranged on a second surface of the membrane, the second surface being opposite of the first surface, such that the membrane is deformed at the position of the piezo actuator upon actuation of the piezo actuator. In the print head, the membrane is pivotably clamped between a first structure layer and a second structure layer such that the membrane pivots at the location of clamping upon deformation of the membrane due to actuation of the piezo actuator.</p> |
