ABSTRACT:
Disclosed herein is a cellular telephone that does not include an integrated microphone and an integrated speaker but that instead requires use of an externally connected microphone and speaker to facilitate voice communication. By omitting any integrated microphone and integrated speaker, the cellular telephone may have increased surface area usable for other purposes, such as a display or keypad. Further, the cost to manufacture the cellular telephone could be incrementally lower than the cost to manufacture a comparable cellular telephone having an integrated microphone and integrated speaker.
