ABSTRACT:
An audio or video apparatus has a housing, a loud-speaker and an acoustic channel. The loud-speaker acoustically cooperates with the channel. One end of the channel opens into an aperture in a side of the apparatus. The dimensions of the loud-speaker and acoustic channel and the positioning thereof within the housing are chosen so as to provide an apparatus that is compact and at the same time produces improved audio reproduction.
