Does anyone know what kind of speakers I would need, and what type of circut to produce sound waves above the range of human hearing (maybe somewhere in the range of 30-40Khz) I need to be able to produce the tones and know that they are accurate to within 4Hz. I also need to hook them up to a timer. (I'm a novice when it comes to circut design)

Any advice on design or sources for parts or information would be most appreciated.
