HTC ThunderBolt Teardown: 3.5mm headphone jack, notification LED, and microphone
The 3.5mm headphone jack, notification LED, and a small, brass-colored sensor are soldered to the HTC ThunderBolt's main PCB. The sensor looks nearly identical to the microphone mounted along the bottom edge of the main PCB. I assume this sensor is also a microphone.
