I would like to find a sonic chip that emits sonic or ultra sonic noise and mount into my pvc bracelets. Can someone tell me where to buy very small emmiters? under one inch in diameter? Thank you. Diane C

Well, I am not sure how much help they will be. When one makes a device that emits sound, too small, it doesn't perform well, normally.
