1. An electronic device, comprising:
a pump system containing a pair of pumps, each of which contains a vibration actuator vibrated by an electromagnetic drive and can discharge fluid according to vibration of the vibration actuator; and
a wearable supply target into which the fluid is supplied from the pump system,
wherein the pump system has:
a vibration suppression mode in which the pair of the pumps are driven so that the vibration of the vibration actuators of the pair of pumps cancel each other, and
a vibration generation mode in which the pair of the pumps are driven so that the vibration of the vibration actuators of the pair of pumps are superimposed on each other.
