Introduction: Hack a Cheap Wireless Handset to Output Via External Speaker
Disclaimer: I am not responsible for any kind of damage done.
A short 10 minute hack to tap into the earpiece output. This cheap handset has no speakerphone capability; hurts my ears like crazy after using it for a while.
I didn't care about impedance or anything, just solder wires to the earpiece connection on the circuit board. I used an old 3.5mm plug and a JST connector to connect the phone to my iPod dock. Volume was a little low so I had to ramp it up a little. Otherwise, it works fine:)
