keychain sound mods

[[email protected]]

Hi all,

Was wondering if anyone here is familiar with those little toy devices
for your keychain that when you push a button, it gives you some sort
of sound or phrase.

What I'm looking for is how to easily access the preamplifier signals.
I want to add my own sounds and phrases to the unit.
It has the features I'm looking for: cheap, small, low power
consumption, and loud.
I know these things usually have a custom blob IC, but i'm hoping the
amplifier sections can be accessed.

The types of units I'm talking about are like the "Yak-Bak", the
Napoleon Dynamite movie phrase thing, the multicolored 8-button sound
effecter, etc.

Any helpful advice would be appreciated. (except for 'build your own
amplifier' (why reinvent the wheel?))

Hi Rich,

I am hoping that just the recorded sounds are on that chip, and if i
input my own line level audio signal to certain traces (or discrete
components) I can get it to directly play it at higher volume... sort
of like adding an auxillary jack to a stereo receiver, it bypasses the
main source of the sounds (AM/FM, etc.) and just amplifies what coming
in externally...

Hope that helps,
