The unit is circular with a domed top (5). The sound from the speaker (2) is directed by baffles (8,9) through holes (10) in the top so the sound only produces maximum power over a limited angle (11). Directional microphones (13) are located in the sides of the unit connect to the outside of the unit through vents (12). There is a connector recessed into the domed top to allow connection to a charger and to the communications system by such as a mobile phone.
