I have used piezo tweeters that come in 3-way speaker systems to generate ultrasonic signals. I think some of them have respose well above the 20KHz range. Maybe upto 50KHz.

I do not know how good are they for reception.

Devantech SRF sensors or Polaroid Senscomp sensors are good plug-in solutions.
