Patent ID: 8577421

Claim:
A mobile terminal comprising: a main body comprising a microphone; a screen display unit comprising speaker-and-receiver units at both ends thereof, the screen display unit being disposed in the main body in such a manner that the screen display unit can slide and rotate with respect to the main body; a control unit that controls each of the speaker-and-receiver units according to a style formed by the screen display unit and the main body; a style detection unit that detects a style formed by the screen display unit and the main body; a first and second amplification units that amplify a broadcast signal or a recorded sound signal; a third amplification unit that amplifies a telephone call signal; and a switch unit that switches a connection between the first, second, and third amplification units and either of the speaker-and-receiver units according to the style based on an instruction from the control unit, wherein during a voice telephone call, in a case of a style in which both the speaker-and-receiver units and the microphone are arranged on the same line with a maximum distance therebetween, the control unit switches the switch unit so that a speaker-and-receiver unit farther from the microphone is operated as a receiver and puts the first and second amplifier units into a non-operated state so that another speaker-and-receiver unit is turned off, in a case of a style in which the screen display unit is disposed perpendicularly to the main body, the control unit puts the third amplifier unit and the microphone into a non-operated state, and in a case of a style in which both the speaker-and-receiver units and the microphone are arranged on the same line with a minimum distance therebetween, the control unit switches the switch unit so that a speaker-and-receiver unit farther from the microphone is operated as a receiver and puts the first and second amplifier units into a non-operated state so that another speaker-and-receiver unit is turned off.
