Abstract An audio output circuit in an electronic apparatus equipped with a composite display function where a plurality of pictures can be displayed on composite screen regions of a single display screen. The circuit includes an audio signal switching circuit for selectively switching audio signals relative to the pictures displayed on the individual screen regions and outputting the selected audio signal to a speaker. The circuit also includes a simultaneous audio output switching circuit for selecting a plurality of audio signals out of those relative to the pictures displayed on the individual screen regions and then outputting the selected audio signals simultaneously through a plurality of speakers. Thus any audio signal(s) relative to the picture(s) displayed on the individual screen region(s) can be heard either selectively or simultaneously through the speaker(s).
An audio output circuit in an electronic apparatus equipped with two loudspeakers and a composite display function for displaying a plurality of pictures on composite screen regions of a single display screen, said circuit comprising: simultaneous audio output means for selecting two audio signals corresponding to two of said plurality of pictures displayed on said composite screen regions, and outputting the selected two audio signals simultaneously to said two loudspeakers.
