Patent ID: 8905524

Claim:
A liquid ejecting head comprising: a nozzle plate with a plurality of nozzles defined therein; a plurality of pressure generation chambers, each in fluid communication with one of the nozzles; a manifold substrate comprising a plurality of manifolds, each configured to supply liquid to at least one of the pressure generation chambers; a plurality of electric elements configured to change pressure of liquid within the pressure generation chambers to thereby eject the liquid via the nozzles; a vibrating element configured to vibrate in response to pressure changes in the liquid within the manifolds; a plurality of cavities provided on the vibrating element at positions that correspond to positions of the manifolds and disposed parallel to the nozzle plate, the plurality of cavities including a first cavity and a second cavity; and an atmosphere exposure channel that provides fluid communication between the first cavity and the atmosphere; wherein at least the second cavity is in fluid communication with the atmosphere exposure channel via the first cavity.
