Abstract: A micro-gas pressure driving device includes a miniature gas transportation module, a covering plate and a tube plate. The miniature gas transportation module includes a convergence plate, a resonance membrane and a piezoelectric actuator. When the piezoelectric actuator is activated to feed a gas into an input tube of the tube plate, the gas is sequentially transferred through a first input chamber, a second input chamber, an inlet, a convergence channel and a central opening of the convergence plate, a central aperture of the resonance membrane, and transferred downwardly through the piezoelectric actuator and an output chamber, and outputted from an output tube of the tube plate. The first input chamber is arranged between the covering plate and the input tube. The second input chamber is defined between the covering plate and the convergence plate. The output chamber is defined between the tube plate and the piezoelectric actuator.
