Title (EN) METHOD AND APPARATUS FOR PROVIDING AN EXPANDABLE ACCOUSTICAL VOLUME
(FR) MÉTHODE ET APPAREIL PROCURANT UN VOLUME ACOUSTIQUE EXPANSIBLE
Abstract:
(EN) A speaker system with an inner element movable in relation to an outer element, where an expanded position is one in which the inner volume of the housing is large and where a speaker is exposed for providing audio. In a contracted position, the volume is smaller and the speaker is protected inside the outer element. This may be provided in a media player (MP3 player) which in the contracted mode provides a signal for headphones, but which in the expanded mode provides the signal to the speaker of the speaker system.
(FR) Système à haut-parleur possédant un élément intérieur mobile en relation avec un élément extérieur, où une position expansée est une position selon laquelle le volume intérieur de l’enceinte est grand et où un haut-parleur est exposé pour fournir des sons. En une position contractée, le volume est plus petit et le haut-parleur est protégé à l’intérieur de l’élément extérieur. Ceci peut figurer dans un lecteur de média (lecteur MP3) qui, en mode contracté, fournit un signal à des écouteurs mais qui, en mode expansé, fournit le signal au haut-parleur du système à haut-parleur.
