How can I increasing output voltage/amplify my laptop's sound card
headphone jack. Tia sal2

Greetings All

I'm generating different sound waves using my laptop
and outputting the sound via my laptop's sound card headphone jack.

I need to increase the output voltage / amplify the output
signal to at least 5v while not adding to much noise to the
signal. What's the best way to go about this?
Preamp/Amplifier/mixer Can anyone recommend a low cost solution?

thanks sal2

Sorry it this is repeated had problems with my posting server

At the risk of being overly obvious, what's wrong with
simply connecting the line-level outputs to an amplifier?
If cost is a concern, your local Radio Shack, Circuit City,
etc. no doubt have some cheap amps to choose from.

Laptops don't usually have a line out, but the headphone output should be accepted by a standard domestic amp.

A little boy squirrel and a little girl squirrel were chattering and playing around when up comes a fox.
The girl squirrel dashed up a tree, but the boy squirrel stood his ground.
"You're pretty brave," said the fox. "Usually squirrels are afraid of me and run to the nearest tree!"
"Listen, bud," snarled the boy squirrel. "Did you ever try to climb a tree when you were in love?"

Try a Boostaroo headphone amp, which RS calls a 33-118.

if you're going that route, might try the FIIO amp; they're selling
all over ebay for like $4 plus postage from the far east. i got mine
from an outfit called justforlive2008, and it arrived within less than
a week for $3.59 postage, right to the house without my having to go
to the store. that's cheaper than us postage, and faster.

I only compute 2v for that device. Meaning its power supply should develope at least
6 volts with the 1.5 v battery.

good point, you're not going to get 5 volts with an aa battery as
power source. i'm an idiot, just ignore me babbling in the corner from
now on....

I might be going in totally the wrong direction here, but I'm sure that
someone will correct me. If you're just looking for increased voltage
(not increased power), what about an audio transformer?

supply should develope at least 6 volts with the 1.5 v
battery.

The Boostaroo is similarly limited by the 2 AA cells that it runs off of.

I modified mine with some wooden dowels that simulate AA cells, so that it
runs off of 5 vdc from an external source. However, its still limited to
just under 2 vrms output. Nevertheless, it helps.

Plan B - try a Behringer headphone amplifier:
