Abstract
A pump system contains a pair of pumps each of which contains a vibration actuator vibrated by electromagnetic drive and can discharge fluid due to drive of the vibration actuator. The pump system has a vibration suppression mode in which the pair of the pumps are driven so that vibration of the vibration actuators of the pair of pumps is cancelled 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 is superimposed with each other.
