Abstract
A pump contains a sealed chamber, a movable wall for changing a volume of the sealed chamber, and a vibration actuator which can be electromagnetically driven for displacing the movable wall to discharge fluid in the sealed chamber to an outside of the sealed chamber. Further, three axes perpendicular to each other are respectively defined as an X axis, a Y axis, and a Z axis. When a direction along the X axis is defined as an X axis direction, a direction along the Y axis is defined as a Y axis direction, and a direction along the Z axis direction is defined as a Z axis direction, an outer shape of the pump is a concave shape in a planar view from the Y axis direction.
