Into synchronous distressed structure, the synchronous distressed structure is equivalent to the substrate 101 of known techniques, but the flow plate of the synchronous distressed structure
21 and flex plate 22 have a variety of embodiment aspects defined in various embodiments in the present invention, and this is various specific
Synchronous distressed structure can be maintained at a required specific gap between the oscillating plate 230 of relative piezo-activator 23
Within (chamber that i.e. certain depth δ is formed), therefore even if when fluid control device 2 is towards the development of microminiaturization, each component
Size design and carry out towards microminiaturization, by the synchronous distressed structure remain to easily this above-mentioned be intended to maintain to have between the two
It is easy to have certain gap, (no matter should because aligning the synchronous distressed structure for the non-planar base that area has reduced using it
It is deformed into bending, cone-shaped, various curved, irregular etc. shape) aligned with a flat board, and no longer it is two large area
Flat board contraposition, but the flat board of the small area of a non-planar base and a large area aligns, therefore can reduce easily between the two
