20-25 kHz transducers
Hi to all.
I'm working on a position tracker that uses ultrasonic transducersfor a program by my university. According to my plans it should work with ultrasounds of about 20-25kHz. However, I am having difficulty finding the microphones/speakers I need for that kind of frequency. I know that components like these were used in early car alarms but can't be found anymore. Can anyone point out a site or a store that might carry such stuff? Thanks! |
