Abstract:
The invention relates to a portable device with an enhanced stereo image, and more particularly a device in which an unsymmetrical placement of loudspeakers is compensated by means of electronic adjustment of the phase and level of the sound. The present invention provides a device (1) comprising a sound source outputting audio channels in stereo, a sound reproduction system delivering electronic sound signals based on the audio channels to at least two loudspeakers (2, 3) for sound reproduction with a stereo image. The device further comprises means for adjusting the level and phase of one of the sound signals to one loudspeaker (2).
