DESCRIPTION JP2001290559
[0001]
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a
portable information processing apparatus such as a notebook computer having an audio output
function.
[0002]
2. Description of the Related Art In recent years, with the improvement of the performance of
information processing apparatuses, a function called multimedia that processes video and audio
has come to be equipped. Under such circumstances, portable information processing
apparatuses such as notebook computers have come to have a speaker section which is an audio
output function for reproducing high-quality sound.
[0003]
Hereinafter, a portable information processing apparatus having a conventional voice output
function will be described. FIG. 7 is an external perspective view showing a conventional example
of a notebook computer which is a portable information processing apparatus having an audio
output function. In the figure, reference numeral 101 denotes a main body of the notebook
computer, 102 denotes a liquid crystal display device rotatably attached to the main body 101,
and 103 denotes speaker units disposed on the left and right of the liquid crystal display device
