I have a Sparkjet voice synthesis chip, and am anxious to "play".
I was wondering... could I just wire the Speakjet output (and ground) directly to the input of a "cheap and cheerful" set of PC active speakers? (I.e. a set of speakers with an itegrated amplifier, independent power supply... the "everyday" sort that you can buy in simple form for about $15, (and upward at many price/ fidelity points) (for playing music, games sound effects, etc) at any computer store...
... the sort you just plug into.... a) the computer's "audio out" socket and b) the household electricity.)
The Sparkfun documentation suggests some 27k resistors, 0.01uf caps, and a 50k pot which I don't have. Do I REALLY have to go find those before I can (safely!) play? (I appreciate that I will get BETTER sounds out of it with the resistors/ caps.)
In an alternate circuit, they just connect a "120 ohm speaker/ earphones", "max 25ma" directly to the chip. Would simple "MP3 player" earphones be suitable?
Thoughts appreciated, but lest I fry the output of the Sparkfun through impatience, please make clear if you are "quessing it would probably be okay", or pretty sure, from a position of knowledge!
