ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to a portable computer, more particularly to a portable computer which can detachably receive a loudspeaker module.
2. Description of the Related Art
A conventional portable computer usually has the tweeter and/or woofer loudspeaker units integral therewith. The following are some of the drawbacks of the conventional portable computer:
1. The loudspeaker units are fixed to the portable computer and cannot be replaced by other kinds of loudspeaker units.
2. The sound effect provided by the loudspeaker units is poor since the resonating space of the loudspeaker mechanism is limited by the interior of the portable computer.
SUMMARY OF THE INVENTION
Therefore, the main object of the present invention is to provide a portable computer that is adapted for use with a detachable loudspeaker module.
Another object of the present invention is to provide a portable computer that is adapted to detachably receive a selected one of a loudspeaker module, a battery module and a disk drive module.
According to the present invention, a portable computer is adapted to detachably receive a loudspeaker module which includes front and rear walls opposite to each other in a first longitudinal direction, a guided wall interposed therebetween, a loudspeaker unit disposed therein and proximate to the front wall to deliver transduced sound therethrough, and a connecting member of a male-and-female electrical connector assembly disposed to extend rearwardly and outwardly of the rear wall, and connected electrically to the loudspeaker unit. The portable computer comprises a mainframe module.
The mainframe module includes upper and lower major walls, a keyboard, first and second side walls, a guiding wall and a mating connecting member. The upper and lower major walls are opposite to each other in a first transverse direction. The keyboard is disposed on the upper major wall. The first and second side walls are respectively interposed between the upper and lower major walls, and are opposite to each other in a second longitudinal direction transverse to the first transverse direction. The first side wall defines a receiving cavity extending towards the second side wall in the second longitudinal direction and terminating at an inner abutment wall which is spaced apart from the first side wall in the second longitudinal direction. The guiding wall is disposed to bound the receiving cavity in the second longitudinal direction, and is adapted to slidably guide the guided wall so as to bring the first longitudinal direction to be aligned with the second longitudinal direction and to bring the rear wall towards the inner abutment wall. The mating connecting member is adapted to form together with the first connecting member, the male-and-female electrical connector assembly. The first mating connecting member is disposed to extend forwardly and inwardly of the inner abutment wall, and is adapted to register with and to fit matingly and snugly with the connecting member when the rear wall is slidably guided by the guiding wall to push against the inner abutment wall.
