Maybe you did but I' ve put it on the wrong place. Do you know something about free ultrasonic transducers?

Most manufacturers will send out 1 or 2 free samples if you give them a business name and address.

I know that but I couldn't find on net manufactorers that produce those low cost ultrasonic transducers. Those which looks like small microphones. If you know some firm that produces them please send me their web address.
Thanks.
