The invention provides for a closeable radio communications device ( 1 ) comprising a housing ( 21 ) having at two portions ( 22,23 ) pivotally mounted to each other to allow relative movement of the portions between a closed position and an opened position. There is a spacing projection ( 30 ) on one of the two portions ( 22,23 ), the spacing projection ( 30 ) being configured such that when the housing ( 21 ) is in the closed position an acoustic chamber ( 31 ) is formed by an inner surface ( 32 ) of the projection and facing surfaces ( 27,28 ) of the respective portions ( 22,23 ). A speaker ( 5 d) mounted inside the housing ( 21 ) is in operative communication with the acoustic chamber ( 31 ).
