    Abstract: The invention provides a message generating apparatus for an electronic equipment. The message generating apparatus includes a look-up table, a first/sucked device, a pressure-sensing device, a processing module, and an interface module. The first/sucked device accommodates a liquid. The pressure-sensing device is installed inside or outside the first/sucked device. The processing module is electrically connected to the look-up table and the pressure-sensing device respectively. The interface module is electrically connected to the processing module, and capable of connecting to an input port of the electronic equipment. The pressure-sensing device senses a pressure of the liquid, and generates a pressure signal in response to the sensed pressure. The processing module determines one of the messages in accordance with the pressure signal and the look-up table, and transmits the determined message through the interface module to the input port.
