A single speaker is utilized for private mode operation when the second housing element (202) is in the substantially open position and speakerphone operation when the second housing element (202) is in the substantially closed position. An internal opening (209), a first sound (270), and a second sound port (211) port sound such that the inside of the first housing element (202) acts as an acoustical suspension enclosure to improve audio quality in the speakerphone mode of operation.
