Mobile terminal

A mobile terminal comprising:

• a case having an inner space, a metal surface and a plurality of holes formed on the metal surface, the plurality of holes communicating with an outside of the case and the inner space;
• a capacitive sensor positioned in the case, spaced apart from the metal surface, and facing the plurality of holes, the capacitive sensor acquiring a variation of an electrostatic capacitance;
• and
• a controller generating a control signal,
• wherein the plurality of holes acquires a touch input of a user,
• wherein the electrostatic capacitance includes:
• a first electrostatic capacitance generated between the user and the capacitive sensor through the plurality of holes;
• and
• a second electrostatic capacitance generated between the metal surface and the capacitive sensor,
• wherein the controller generates a control signal when the capacitive sensor acquires a variation of the first electrostatic capacitance and a variation of the second electrostatic capacitance, and
• wherein the mobile terminal further comprises:
• an input module installed at the case and a button having the plurality of holes, the input module acquiring the touch input of the user.
