A microporous vibration device can be applied to an atomizer or a filter, and mainly comprises a vibration element and at least one hydrophobic microporous membrane. The vibration element is an annular structure body with a through hole at its center, and the hydrophobic microporous membrane is covered to one side of the vibration element to completely cover the through hole. The hydrophobic microporous membrane is a biaxially oriented membrane and obtained by using hydrophobic powders subjecting to a mixing, stirring, setting, baking and rolling, of which the surface is formed with a plurality of micro pores corresponding to a set pore size in order to reduce expensive cost of traditional nozzle sheet that adopts metals or polymer sheets and must be processed by physical deposition, laser drilling, etc., so as to greatly reduce manufacturing cost and be mass produced. Moreover, compared to the nozzle sheet manufactured by the conventional process, the set pore size is smaller, thereby improving usage effect.一種微孔振動裝置,供應用於霧化器或過濾器,其主要包括一振動元件及至少一疏水性微孔膜。其中該振動元件係中心具有一穿孔之圓環狀結構體,且該疏水性微孔膜覆設於該振動元件之一側面以完全遮蔽該穿孔。該疏水性微孔膜係使用疏水性粉料經混合、攪拌、靜置、烘焙及壓延之一種雙向拉伸膜材,其表面形成對應一設定孔洞尺寸的複數個微孔洞,以降低傳統噴孔片採用金屬或是高分子聚合片材必須使用物理沈積、雷射鑽孔等製程的昂貴成本,故能大幅降低製造成本且大量製造;並且,該設定孔洞尺寸相較於傳統製程而製得之噴孔片更小而提昇使用效果。1‧‧‧微孔振動裝置11‧‧‧振動元件111‧‧‧穿孔12‧‧‧疏水性微孔膜121‧‧‧微孔洞122‧‧‧結點123‧‧‧原纖13‧‧‧結構件14‧‧‧支撐材141‧‧‧肋條
