Abstract:
1. A mobile communication device comprising: telephone circuitry having a front side, the front side of the telephone circuitry having a top end including a speaker and a bottom end including a microphone; and a housing having a top shell including a speaker interface and a bottom shell including a microphone interface, the top shell and the bottom shell being disconnectable; each interface including a gasket that allows sound penetration while preventing the entry of water and contaminants; the bottom shell having a unitary keypad interface sealed to the bottom shell with conductive areas that interface with contacts on the telephone circuitry; wherein the housing is adapted to substantially enclose the telephone circuitry when the top shell and the bottom shell are mated in a direction along a length of the telephone circuitry from the top end with the speaker to the bottom end with the microphone, at a parting line perpendicular to the mating direction and arranged such that a circumference and surface area to be sealed between the top and bottom shell is minimized.
