First Claim
Patent Images
1. A notebook computer comprising:
- a first housing having an expansion slot; and
a woofer module installed in the expansion slot for generating a low-frequency signal, the woofer module capable of removing from the expansion slot, the woofer module comprising;
a second housing;
a speaker unit positioned in the second housing far generating the low-frequency signal;
a predetermined room positioned in the second housing for resonating the low-frequency signal;
a bass reflex duct positioned in the second housing, the bass reflex duct being used for connecting an output vent of the predetermined room and an output vent of the second housing so that the low-frequency signal is outputted from the output vent of the second housing; and
an absorbing member disposed on the second housing to alleviate the vibration caused by the woofer module.

Abstract
A woofer module is used for outputting alow-frequency audio signal, and can be inserted into and removed from anexpansion slot of a portable computer. The woofer module has a housing, a speaker unit positioned inside the housing for generating the audio signal, a predetermined space positioned inside the housing for resonating the audio signal, and a bass reflex duct positioned inside the housing which is connected to an output vent of the predetermined space and an output vent of the housing for transmitting the audio signal from the output vent of the housing to an ambientenvironment.
