Step 13: Speakers and Headphone Jack
To make Beemo's surround sound head speaker sides, I used a 2 1'' diameter speaker. I then used around 5 '' flexible earphone wire to join the two in parallel (connecting each of the positive leads together as well as both of the negative leads together). The way the speakers are soldered on the Game Boy Color's circuit board is negative on the top and positive on the bottom. Replace their half inch speaker with the new dual speakers.
For the headphone port, I wanted the headphone one to be placed very stylishly so took a tip from Apple and moved it from the bottom of the Game Boy, to the inside top of Beemo so it could be inserted like an iPod's. I pretty much simply unsoldered it from the Game Boy Color's circuit board and then soldered each lead (5) to long 6'' wire.
