Atypic amplifier design project

[gwuber]

Hello everybody,

I want to build an amplifier for a friend of mine who is an artist playing with sound : he uses amplifiers with a speaker connected in the inputs and outputs. And he had several devices burnt already.
So I'd like to make a specific amp for such a practice, but I know too little electronics.

Any advices ?

Thanks !

so he uses a little loudspeaker as microphone, for input
then an amplifier feeding another speaker

what we need to be able to make recommendations is
some data or brand of these speakers
especially the one used at the input!

a good way here, is maybe to use a readymade amplifier IC
... a so called Chip Amp:

... with 2 power supply pins
... with 2 input pins
... and 1 output pin
--------------- simple as it gets

see more info and stuff in the chip amp forum:
