How to build a tiny earpiece

  1. Apr 4, 2007 #1

    I'd like to design and build an ear piece 'induction receiver'. It would function as a loudspeaker which would fit inside the ear, and would receive a signal from a bluetooth transmitter which would be worn around the neck. So, a mobile phone call could be heard in the ear piece as the bluetooth transmitter would send a signal to the ear piece.

    I'd like to build the induction receiver ear piece to be as small as possible, so it can fit inside the ear completely... about 3mmX3mmX7mm would be good. I'm just looking for information on the anatomy of an induction receiver, how it works and what parts are needed to build one. I'm guessing the largest component of the earpiece would have to be the battery. Any advice would be greatly appreciated, thanks!
