Claim:
1. An apparatus comprising: a casing; a first substantially horn shaped structure located within the casing and configured to couple and amplify sound from a first speaker of a further apparatus configured to be coupled to the casing; and a second substantially horn shaped structure located within the casing and configured to couple and .amplify sound from a second speaker of the further apparatus, wherein the first substantially horn shaped structure and the second substantially horn shaped structure each comprise a mouth portion with a physical separation dimension greater than a physical separation dimension of a first speaker outlet and a second speaker outlet of the further apparatus; a detector on the further apparatus, the detector configured to determine the first speaker and the second speaker of the further apparatus are coupled to the first substantially horn shaped structure and the second substantially horn shaped structure, respectively, on the apparatus; a digital signal processor on the further apparatus, the digital signal processor configured to output an audio signal to the first speaker and to the second speaker dependent on the detector, the digital signal processor being configured to modify at least one of a frequency response and a loudness of the audio signal dependent on the detector; and an indicator on the apparatus and configured to be detected by the further apparatus such that the audio signal can be tuned based on the digital signal processor when the indicator is detected; wherein the further apparatus is a portable apparatus comprising at least the first speaker and the second speaker; and wherein the sound from the first speaker and the second speaker is amplified through the first substantially horn shaped structure and the second substantially horn shaped structure, respectively, and wherein stereo sound quality from the first speaker and the second speaker is improved due to a widening of a separation distance between the first speaker and the second speaker due to the first substantially horn shaped structure and the second substantially horn shaped structure.
