Pump system and electronics device

A pump system, comprising:

• a pair of pumps, each of which contains a vibration actuator having an elongated movable body which can perform reciprocating rotation around a shaft portion by electromagnetic drive, a pair of sealed chambers connected to a suction port and a discharge port, movable walls respectively displaced by the vibration actuator to change volumes of the pair of sealed chambers, and a housing containing the vibration actuator, the pair of sealed chambers and the movable walls therein, and which can discharge fluid due to the vibration actuator,
• wherein each of the pair of pumps can be vibrated by the reciprocating rotation of the movable body,
• wherein the pump system has:
• a vibration suppression mode in which the pair of pumps are respectively driven by AC voltages whose phases are shifted from each other by 180°,
• a first vibration generation mode in which the pair of pumps are respectively driven by in-phase AC voltages, and
• a second vibration generation mode in which the pair of pumps are respectively driven by AC voltages whose phases are shifted from each other by 90°, and
• wherein the vibration actuator further has:
• a shaft portion provided on the housing for supporting the movable body so that the movable body can perform the reciprocating rotation with respect to the housing and serving as a rotational center of the reciprocating rotation of the movable body,
• a pair of magnets respectively fixed to both end portions of the movable body, and
• a pair of coil core portions provided on the housing so as to respectively face the pair of magnets.
