An exemplary inflatable keyboard includes an inflatable bag, a flexible printed circuit board (FPCB), an inflating unit electrically connected with the FPCB, an inflating button and a USB interface connects to a host device. The inflatable bag includes a faceplate portion and at least one key. An inlet valve and an outlet valve mounted on the inflatable bag. The FPCB receives a startup signal and a shutdown signal via the USB interface, used as an inflate signal and a deflate signal respectively. The inflating button produce an inflate signal and a deflate signal respectively when the inflating button is actuated by a user. The inflating unit includes a pressure gauge, an air pump, and a valve control device. The inflating unit configured for inflating the inflatable bag to the inflated state upon receiving an inflate signal, and allowing deflation of the inflatable bag upon receiving a deflate signal.
