I want to build an electronic device that transmits ultrasound

[JoshHolloway]

I want to build an electronic device that transmits ultrasounds (I guess that is in the LF frequency range [?]).

Does anyone know where I can find a kit that creates ultrasounds?

 

[JoshHolloway]

Or does anyone know where I could find schematics of how to build something like that?

I guess what I really mean is an Ultrasound Pulse Generator.

Ultrasound is high frequency.

What do you want to do with it?

 

[JoshHolloway]

To shut a neighbors dog up! Essentially I want to build an electronic dog whistle.

I googled ultrtasonic transmitter kit, and got lots of hits. Here's the hit list:

I'm not sure ultrasound will work for quieting the neighbor's dog, though. There are more conventional ways to do that, including talking to the neighbor. And in the end if nothing else works, at least in the US, there is small claims court where you can keep taking the owner to court and winning judgements against them. Talking to the neighbor to work things out usually works, though.

Ya, but how fun is that? I really just want to build it.

So berkeman, could I build this thing and put a speaker on it to transmit the sound frequency at 24kHz?

Nifty little widget. You don't connect an external speaker -- the piezo transducer elements are the silver round things that are included in the kit. That looks like a good starting point.
