Wolfson Microelectronics WM7121 Top Port Analogue Silicon Microphone

Wolfson Microelectronics WM7132 Bottom Port Analogue Silicon Microphone

Motoroogle again shows off its novelty; the X's vibrator motor is soldered right to the motherboard. The wonders never cease.

Like any good warrior, we hold onto the ears EMI shields of our enemies.
