摘要 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 (5d) mounted inside the housing (21) is in operative communication with the acoustic chamber (31).
