Dear Everyone,
I was wondering is it possible to activate a crystal 20KHz by just applying a direct DC power supply in series with it?

Dear Everyone,
Is it possible to activate a crystal (20KHz) by just directing a DC voltage in series with it?
no.
remember it is still just a rock.
u can use a cmos inverter to make it activate.
In Series? I think not, maybe with some other device in parallel.You can probably use a semiconductor multivibrator, any tunable sci, or cmos depending on what you're trying to achieve.
what is your application ?

What do you mean? What kind of a crystal?

My application is just to activate a speaker with an impedance of 8 ohm and 0.3W. An ocillatory wave should do the activation.
well, if that's the case;
we use to use 1.5 - 9 vdc cells to test them, you should get a click.
wait a minute, did you ever own a volx vvagon ? a ford pick up?
did i do that for you once ? };-)
don't leave it touch too much, once you've established your purpose.

No. See
You can get a pre-packaged oscillator which contains the crystal and the oscillator circuit. You supply DC power to two pins, and a third pin provides the output. However, these might be hard to find in
20 KHz; most of them start at 32 KHz and go up from there.You might also ask in sci.electronics.basics .
