Abstract

Cette invention a pour objet un terminal portable, par exemple un téléphone portable, dont le traitement, incluant un traitement à sortie vocale, présente une portabilité et une qualité sonore perfectionnées. Ce terminal portable possède un haut-parleur (20) composé d’un boîtier d’arrimage (21) et d’un boîtier de mouvement (22). Ce boîtier de mouvement (22) passe d’une position bloquée dans le boîtier d’arrimage (21) à une position de projection depuis un téléphone portable (10). Lorsque le boîtier de mouvement (22) se trouve dans cette position de projection, l’espace interne dans le boîtier de mouvement (22) et l’espace d’arrimage dans le boîtier d’arrimage sont combinés pour former une même caisse de résonance.
