Abstract

The invention discloses a notebook computer, comprising a first loudspeaker set, a second loudspeaker set, a power detection unit and a sound source unit. The power detection unit is used for detecting whether the notebook computer uses an external power supply currently so as to output detection results. The sound source unit is coupled to the first loudspeaker set, the second loudspeaker set and the power detection unit. The sound source unit drives the first loudspeaker set for sounding. Moreover, the sound source unit can determine whether to drive the second loudspeaker set according to the detection results.

Description

technical field [0001] The present invention relates to a notebook computer (Notebook Computer), and in particular to a notebook computer with double stereo (Double Stereo). Background technique [0002] In order to increase the sense of reality and presence for users listening to music or viewing multimedia files, the development of sound effect technology has gradually evolved from mono (Mono) technology to stereo (Stereo) technology, so that users can hear more through speakers. Real sound quality effects. Since humans rely on a pair of ears to listen to the surrounding sounds at the same time, the so-called stereophonic technology is to configure a speaker (Speaker) on the left and right sides of the user, wherein the speaker on the left plays the audio from the left channel. , while the speaker on the right plays audio from the right channel. In this way, users will be able to enjoy the stereo effect as if they were on the scene. [0003] At present, in addition to b...
