摘要： A head unit includes a liquid discharge head and circuitry. The liquid discharge head includes a nozzle plate having a nozzle, a liquid chamber to store a liquid to be discharged from the nozzle, a valve body in the liquid chamber, a valve body coupler coupled to the valve body, and a driver to drive the valve body coupler to move the valve body. The valve body is movable between a contact position at which the valve body contacts the nozzle plate to close the nozzle and a separated position at which the valve body is separated from the nozzle plate to open the nozzle. The circuitry moves the valve body between the contact position and the separated position to open and close the nozzle in a first operation, and applies vibration to the valve body while the valve body is temporarily held at the separated position in a second operation.

摘要： Provided is a liquid droplet forming device including: a liquid container capable of containing a liquid; a membranous member disposed at a bottom of the liquid container and including a discharging hole; a deforming unit capable of deforming the membranous member; and a driving unit configured to drive the deforming unit by outputting a discharging signal for deforming the membranous member to discharge the liquid or a suppressing signal for suppressing residual vibration of the membranous member, wherein the suppressing signal is a signal based on natural vibration period T0 of the membranous member, wherein an amplitude of the suppressing signal is lower than or equal to an amplitude of the discharging signal, and wherein interval time Ti from when outputting of the discharging signal is ended until when outputting of the suppressing signal is started satisfies a formula: Ti=(m−½)×T0, where m represents a positive integer.
