    摘要: An inkjet recording head includes a base member, an ink channel unit, a plurality of piezoelectric elements, and a dynamic vibration absorber. The ink channel unit is formed with a plurality of nozzle holes and a plurality of ink pressure chambers. The ink channel unit includes a diaphragm that defines part of each ink pressure chamber. Each piezoelectric element has one end fixed to the base member and another end attached to the diaphragm. Each piezoelectric element generates displacement in a displacement direction for deforming the diaphragm to eject ink droplets through a corresponding one of the plurality of nozzle holes. The dynamic vibration absorber is mounted on the base member for damping vibrations of the base member due to a resonance, the resonance occurring in a frequency range less than or equal to a predetermined frequency.

    摘要: An inkjet recording head includes: a nozzle plate having nozzles arranged in a row; a plurality of pressure generating chambers communicating to the nozzles, the plurality of pressure generating chambers including a first pressure generating chamber and a second pressure generating chamber; a diaphragm formed on one face of the pressure generating chamber; a common ink chamber for supplying the ink to the plurality of pressure generating chambers; and a piezoelectric element for displacing the diaphragm. The first pressure generating chamber is disposed on one side of the nozzles and a second pressure generating chamber is disposed on the other side. The first and second pressure generating chambers are opposed to each other across the nozzles so that the central lines of the first and second pressure generating chambers are almost coincident.
