    • A fluid control device includes a vibrating plate unit, a driver, a flexible plate, and a base plate. The vibrating plate unit includes a vibrating plate including first and second main surfaces, and a frame plate surrounding the surrounding of the vibrating plate. The driver is bonded to the first or the second main surface of the vibrating plate and vibrates the vibrating plate. The flexible plate includes a hole provided therein, and is bonded to the frame plate so as to face the vibrating plate. The base plate is bonded to the main surface of the flexible plate on a side opposite to the vibrating plate. A size relationship between the coefficients of linear expansion of the material of the base plate and the frame plate is equal to a size relationship between the coefficients of linear expansion of the material of the vibrating plate and the driver.
    • 流体控制装置包括振动板单元,驱动器,柔性板和基板。 振动板单元包括包括第一和第二主表面的振动板和围绕振动板周围的框架板。 驱动器结合到振动板的第一或第二主表面并使振动板振动。 柔性板包括设置在其中的孔,并且与框架板接合以面对振动板。 基板在与振动板相对的一侧与柔性板的主表面接合。 基板的材料和框架板的线膨胀系数之间的尺寸关系等于振动板的材料和驱动器的线膨胀系数之间的尺寸关系。

    • A fluid control device includes a vibrating plate unit, a driver, and a flexible plate. The vibrating plate unit includes a vibrating plate with first and second main surfaces, a frame plate surrounding the vibrating plate, and a link portion linking the vibrating plate and the frame plate and elastically supporting the vibrating plate against the frame plate. The driver is on the first main surface of the vibrating plate, and vibrates the vibrating plate. The flexible plate having a hole faces the second main surface of the vibrating plate, being fixed to the frame plate. At least a portion of the vibrating plate and the link portion 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.
    • 流体控制装置包括振动板单元,驱动器和柔性板。 振动板单元包括具有第一和第二主表面的振动板,围绕振动板的框架板和连接振动板和框架板并将振动板弹性地支撑在框架板上的连杆部分。 驱动器位于振动板的第一主表面上,并振动振动板。 该柔性板具有面向振动板的第二主表面的孔,固定在框架板上。 振动板和连杆部分的至少一部分比框架板的厚度薄,使得振动板的部分的表面和连接部分在柔性板的侧面上的表面可以与柔性的 盘子。

    • A small-sized, low-profile fluid pump having high pumping capabilities includes an actuator and a planar section including a metal plate. The actuator includes a disk-shaped piezoelectric element attached to a disk-shaped diaphragm. As a result of application of a square-wave or sine-wave drive voltage, the actuator performs a bending vibration from the central portion to the peripheral portion. The peripheral portion of the actuator is not restrained. The actuator performs a bending vibration in the state in which it is in proximity to the planar section while facing the planar section. A center vent is provided at or in an area adjacent to the center of an actuator facing area of the planar section that faces the actuator.
    • 具有高泵送能力的小尺寸,低轮廓流体泵包括致动器和包括金属板的平面部分。 致动器包括附接到盘形隔膜的盘形压电元件。 作为施加方波或正弦波驱动电压的结果,致动器从中心部分到周边部分执行弯曲振动。 致动器的周边部分不受约束。 致动器在面向平面部分的同时在平面部分附近的状态下执行弯曲振动。 中心通气口设置在与面向致动器的平面部分的致动器面向区域的中心相邻的区域处或其中。
