Here's some pictures of a beta setup for a microphone and speaker attachment to use with VOIP. I've yet to finalize a design for the case, which will be silicone, and the speaker will retain it's specs but be rectangular instead of circular. The speaker is 8 ohm 0.5 watt and the board has an amp and battery, so you could listen to music as well. Let me know what you think, ideas, etc. I'll give details to anyone interested, but the hardware only costs $7.00 US on ebay. If you've got rudimentary soldering skills and some wire, you're good to go.
