Diaphragm pump adjustment portion for adjusting resonant frequency of diaphragm

Abstract

[Object] To provide a technology or the like capable of improving driving efficiency of a diaphragm pump. [Solving Means] A diaphragm pump (10) according to the present technology includes a first diaphragm (1a), a second diaphragm (1b), and an adjustment portion (11). The first diaphragm (1a) includes a first member including a first elastic portion (5a), and a first drive unit that elastically deforms the first elastic portion (5a) by drive of the first drive unit. The second diaphragm (1b) includes a second member that includes a second elastic portion (5b) and forms a space (13) with the first member, a fluid flowing in the space, and a second drive unit that elastically deforms the second elastic portion (5b). The adjustment portion (11) is provided to at least one of the first diaphragm (1a) or the second diaphragm (1b) and is for adjusting a resonant frequency of the at least one of the first diaphragm (1a) or the second diaphragm (1b).
