ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to a portable computer, more particularly to a portable computer having a movable loudspeaker unit.
2. Description of the Related Art
A portable computer is usually installed with a CD-ROM drive for playing an audio disc. However, a conventional portable computer has a loudspeaker unit fixed in a mainframe module or a display panel module thereof. When an audio disc is played, audio output radiates in a fixed direction so that the user cannot adjust the direction of the audio output toward him. When the display panel module covers the mainframe module, the audio output is interrupted so that an external loudspeaker unit is needed to hear the audio output.
SUMMARY OF THE INVENTION
Therefore, the main object of the present invention is to provide a portable computer having a movable loudspeaker unit which can be adjusted to face the user.
Another object of the preferred invention is to provide a portable computer having a movable loudspeaker unit which can still provide an audio output even though a display panel module is closed.
According to the present invention, a portable computer includes a mainframe module, a display panel module, a loudspeaker unit and a connecting unit. The mainframe module has a rear side and a cavity. The display panel module has a rear side connected pivotally to the rear side of the mainframe module for moving between a closed position and an opened position relative to the mainframe module. The loudspeaker unit has a loudspeaker enclosure disposed movably inside the cavity, and a loudspeaker mechanism received in the loudspeaker enclosure. The connecting unit is connected to the loudspeaker enclosure, and is mounted movably to the mainframe module inside the cavity for permitting the loudspeaker enclosure to move outwardly or inwardly of the cavity.
