Abstract

The invention provides an inkjet head, an inkjet recording device and a manufacturing method of a vibration damping component. The inkjet head is provided with the components of pressure chambers which are arranged in more than two rows; a common ink chamber which is communicated with the pressure chambers through ink inlets of the pressure chambers; and a vibration damping component which is configured in the common ink chamber and is provided with a vibration damping frame and a flexible film. At least the surface, which faces the ink inlets, of the vibration damping frame is made of the flexible film. The pressure in a chamber which is composed of the vibration damping frame and the flexible film is negative.

Description

technical field [0001] The present invention relates to an inkjet head, an inkjet recording device, and a method for manufacturing a damping member, and in particular, to an inkjet head, an inkjet recording apparatus, and an inkjet recording apparatus capable of reducing the influence between columns of pressure chambers caused by crosstalk. Apparatus and method of manufacturing a vibration-damping component. Background technique [0002] Inkjet heads sometimes have uneven ejection performance due to pressure waves generated by driving. This is because a pressure wave generated in a pressure chamber by driving propagates to another pressure chamber communicated with a common ink chamber, and so-called crosstalk occurs in which the emission characteristics of the pressure chamber through which the pressure wave propagates fluctuates. [0003] Conventionally, as a technique for reducing the influence between pressure chambers caused by crosstalk, the following technique has b...
