This is a good example in where my electronics hobby was put to good use this evening,
We had a phone call on the answering machine at home, and the person was very soft spoken, and with the base unit volume all the way up we just could not make out the message, left on the machine.
Therefor, I got out my calculator and pen and pad, and whipped up this circuit.
I designed it for 8v. to run off a portable 9 volt battery, so I could make it on my breadboard and carry it upstairs to the phone base unit.
I just placed the input spkr. against the phone base, then played the message on the machine, and it came out loud enough to be able to hear it standing away from the output spkr. about 3 ft. It had substantial volume and the sound quality was very good.
