ABSTRACT:
A folding electronic device includes an operation unit, a display unit, a memory unit, a pair of speakers, a detection switch, and a switch. A plurality of information input keys are arranged on the operation unit. The display unit is integrated with the operation unit so as to be foldable, and displays at least image information. Sound source data is stored in the memory unit. A pair of speakers for a left channel and a right channel can be driven in a closed state in which the display unit is folded. The detection switch detects the open state in which the display unit is not folded or the closed state in which the display unit is folded. The switch switches paths through which the sound source data stored in the memory unit is output to the pair of speakers on the basis of an output from the detection switch.
