Electronic device and fluid driving device

The invention discloses a fluid driving device which comprises a shell and an oscillation membrane. The shell is provided with a fluid space, a liquid inlet channel, a liquid outlet channel and a gas port. The oscillation membrane can be arranged in the fluid space in an oscillation mode, and the fluid space is divided into a liquid flow channel and a gas flow channel which are not communicated with each other. The liquid flow channel and the gas flow channel are used for containing liquid and gas respectively. The liquid inlet channel and the liquid outlet channel are communicated with the liquid flow channel, and the gas port is communicated with the gas flow channel. When the oscillation membrane is driven to generate oscillation to compress the gas flow channel, the oscillation membrane drives the liquid to enter the liquid flow channel from the liquid inlet channel and drives the gas to flow out of the gas flow channel from the gas port. When the oscillation membrane is driven to generate oscillation to
