Abstract

An improved mobile electronic device 100 with a unique thin and cost-effective form and design can have a large display 170 and a large full qwerty keypad 138 on the outward surface and can have a capacitive touchpad 186 on the inward surface of the flip 102 or slide that facilitates navigation on the display and can detect and recognize the flip or slide position within the mobile electronic device. A pattern of capacitive traces or wires 202 can be laid out within the layers of a printed circuit board to detect a user's finger gestures without enlarging or adversely impacting the size of the mobile electronic device. The attractive mobile electronic device can also provide for the use of a speaker port 196 underneath a removable battery door 194 and a way to seal a port under a battery door for audio enhancement.
