Micro Earpiece

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.
