Abstract
A liquid discharge head includes: multiple nozzles; multiple individual chambers respectively communicating with the multiple nozzles; a common chamber communicating with each of the multiple individual chambers; multiple fluid restrictors between each of the multiple individual chambers and the common chamber; and multiple actuators driven to cause a liquid in the multiple individual chambers to be discharged from the multiple nozzles, a meniscus formed at each of the multiple nozzles has a natural period of vibration different from each of: a resonant period of the common chamber; half of the resonant period of the common chamber; and a quarter of the resonant period of the common chamber.
