Project Description:
Hello Guys and gals !

I need a CHEAP no fuzz design that can be mass produced .

I need a ultrasonic generator with two output channels of atleast 50W or more.
We need to find a balance for price and power, the highest bang for the lowest buck ....

There need to be a stereo audio input so i can supply audio signal for the amplifier .
im using the bolt on type of ultrasonic transducer that needs high voltage so there must be an inductor / capacitor stepup circuit onboard.

Im going to use this board for a type of directional audio ( deliver infrasound by ultrasound, not in air btw), read up on LRAD and the type of modulation used.
i would if possible like someone that can create a built in modulation for this purpose.

Here is a snip about LRAD :
Snip "
There is one more way to experiment with ultrasonic air transducers like this one, and that is to try replicate the effects of LRAD(tm). For that you'd need two transducers. LRAD(tm) works on a principle that when you cross two ultrasonic beams (say 20 and 25 kHz), you generate the difference between the two (5kHz sound) originating at the point where the two beams cross. Or you could use two same frequencies (23kHz and 23kHz) and FM modulate one of them with voice or audio. And another way of doing that is to phase-shift one of the 23kHz tones instead of frequency-modulating it. That delivers sound to long distances and makes it appear that the sound originates right next to you or inside your head, even though you're dozens of yards away from the transducers. And with more power, distances of hundreds of yards can be reached, which is what LRAD(tm) does.
" end snip.

If you dont understand how ultrasound and LRAD works, dont bid.
If you think you can charge 1000 dollars, dont bid,

Give me bids, ideas and questions.

The highest bang for the lowest buck wins.

I would like a hourly budget AND a estimate what the end price would be .
