Abstract
A flip-up type mobile telephone terminal enables a user to answer an incoming call even without opening a flip. A speaker unit includes first and second speakers installed at front and rear sides of the flip, respectively, facing the opposite directions. The speaker unit further includes a partition intervening between the first and second speakers to prevent interference therebetween. A flip-open sensor senses an open state of the flip. A controller detects the open state of the flip through the flip-open sensor, and switches a voice output path to the first speaker when the flip is closed and to the second speaker when the flip is open. A microphone device is installed in a bottom of the body.
