Terminal device and pressure touch method

The invention provides terminal equipment and a pressure touch method. The terminal device comprises: a cavity is formed by the touch screen and the shell, an air pressure sensor and a processor; theair pressure sensor is arranged in the cavity and is used for detecting the air pressure in the cavity when the touch screen or the shell is subjected to pressing operation; the processor is used fordetermining the pressure of the pressing operation according to the air pressure change value and one or more pressure calculation coefficients, wherein the one or more pressure calculation coefficients comprise deformation coefficients corresponding to the position of the pressing operation, and the deformation coefficients are coefficients used for indicating the deformation quantity of the screen. The pressing force of the user on the terminal equipment is determined by utilizing the air pressure change value in the cavity, the size of the terminal equipment does not need to be increased, and the cost of the termina
