I have read about the need to have a duplex coil in a telephone to block the sound of your own voice from reaching your ear...the reason given on a few websites I have found is that the original design of the telephone had the microphone and speaker wired together.
So here is my question...
Why did the original telephone have this design feature? Why did they wire it this way?
