Abstract:
A liquid discharge head includes a nozzle plate in which a plurality of nozzles to discharge a liquid is formed in a nozzle array direction, a channel plate including partition walls to form a plurality of individual chambers communicating with the plurality of nozzles, respectively, a diaphragm bonded to the channel plate to form a wall of the plurality of individual chambers, and a plurality of electromechanical transducers bonded to the diaphragm to deform the diaphragm to generate a pressure in the plurality of individual chambers, and a cycle of vibration of natural vibration generated in the liquid in the plurality of individual chambers is equal to or larger than a cycle of a primary mode of lateral vibration of the plurality of electromechanical transducers in the nozzle array direction.
