A mobile phone includes a base, a screen connected to the base, and a control panel; the base has a signal receiving plate, and a slide block on the upper side, which can slide on the base in any direction; the control panel has a connecting hole on a lower side, and it is joined to the slide block with the connecting protrusion being passed through the connecting hole; the control panel can be positioned such that when the control panel is slid on the base, the signal source will move within the signal receiving plate for the signal receiving plate to receive signals from the signal source; thus the control panel can function like a mouse; the control panel can be turned to such a position as not to cover the signal receiving plate, thus allowing one to input signals by means of touching the signal receiving plate.
