摘要： Provided is a suction device that can suppress sound and vibration during use. A suction device includes a flow-passage forming section (1) having a suction port (20) from which fluid is sucked, a discharge port (29) from which the fluid is discharged, and a flow passage (2) which is sealed from an outside except at the suction port (20) and the discharge port (29) and through which the fluid flows, and a piezoelectric driving part (33) that generates a flow of the fluid in the flow passage (2). The piezoelectric driving part (33) includes a diaphragm (37) and a piezoelectric element (34) as a moving part that transmits driving force to the fluid. The moving part is entirely disposed inside the flow passage (2).

摘要： A fluid control device (101) includes a vibrating plate unit (160), a driver, and a flexible plate. The vibrating plate unit includes a vibrating plate (141) with first and second main surfaces, a frame plate (161) surrounding the vibrating plate (141), and a link portion (162) linking the vibrating plate and the frame plate and elastically supporting the vibrating plate against the frame plate. The driver (142) is on the first main surface of the vibrating plate, and vibrates the vibrating plate. The flexible plate having a hole (152) faces the second main surface of the vibrating plate (141), being fixed to the frame plate (161). At least a portion of the vibrating plate (141) and the link portion (162) are thinner than the thickness of the frame plate so that the surface of the portion of the vibrating plate and the link portion, on the side of the flexible plate, can separate from the flexible plate.

摘要： A fluid control device (101) includes a vibrating plate unit (160), a driver (142), and a flexible plate (151). The vibrating plate unit (16) includes a vibrating plate (141) including a first main surface and a second main surface, and a frame plate (161) surrounding the surroundings of the vibrating plate (141). The driver (142) is provided on the first main surface of the vibrating plate (141), and vibrates the vibrating plate. The flexible plate (151) has a hole (152) formed thereon. Furthermore, the flexible plate (151) faces the second main surface of the vibrating plate (141), and adheres to the frame plate by the adhesive agent (120) that contains a plurality of particles (121) arranged such that the plurality of particles are interposed between the flexible plate and the vibrating plate.
