P portable electronic device (1) comprising a first flap (5) and a second flap (4). The first flap extends longitudinally along a first axis (d1). The portable electronic device also comprises a first audiophonic portion (3), and a second audiophonic portion (2) having the same function as the first audiophonic portion. The audiophonic portions are arranged in such a way that their orthogonal projections on the first axis of which are distinct, so as to obtain a stereo effect in the direction of the first axis. The orthogonal projections of the audiophonic portions to a second axis (d2) substantially perpendicular to the first axis of which are distinct, so as to obtain a stereo effect in the direction of the second axis. / p
