Im following this instructable http://www.instructables.com/id/3-Emergency-Solar-Radio/?ALLSTEPS to make my own solar radio, and im trying to use some laptop internal speakers i salvaged and trying to wire them to a 3.5 mm headphone jack but its not working, what should i do? pic looks alot like mine (i salvaged mine from a lenovo x220 tablet)
The output of a headphone jack can only power the very small speakers found in headphones.

Strange since it works when I attach the wires to this.

Then you fucked something up.
i had one of those dollar-store radios where the 3.5mm jack was purposely wired without a ground, such that the output was mono, effectively putting the 2 headphone speakers in series.
i'm not suggesting this is your case, it's just one of the possibilities that you can figure out much quicker by doing trial an error than asking strangers for help.
Alpha toss
They are mono speakers running stereo which is why it works with the adapter. Take one speaker out and it will work without the adapter. get a y jack male female female from radio shak snip ends wire problem solved.
