Abstract: A method (200) and apparatus (100) that synchronizes audio levels of a device and an audio accessory is disclosed. In at least one embodiment, the apparatus (100) includes a housing (110) and a local speaker (130) coupled to the housing. The apparatus also includes a wireless speaker interface (180) coupled to the housing. The wireless speaker interface can be configured to send an audio signal to a remote separate speaker module wirelessly coupled to the wireless speaker interface and can be configured to send and receive volume level status data to and from the remote separate speaker module. The apparatus further includes a volume adjustment user interface (160) that can receive a user input to adjust the volume level of the remote separate speaker module. The apparatus additionally includes a controller (120).

Abstract: 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).
