Micro Earpiece
From HeatSync Labs Wiki
Overview
The idea is to make that impossibly small radio that fits inside your ear. Here is a breakdown of how it could work:
- Your cell phone is the transmitter/receiver. This sits in your pocket connected to whomever you wish to talk to.
- The phone connects via bluetooth or a headset wire to an induction transmitter that is worn around your neck.
- The necklace is actually a wire loop that acts as an antenna coil.
- In your ear is an earpiece with an induction receiver than can pick up the transmission from the transmitter.
- The microphone you speak into is clipped to the inside of your shirt.
