Do you have a schematic for it? So how long will the "transducer" be on with your creation of 100kilohertz.

post a schematic of your astable or a description of the values used and where they are connected to the 555. Also, what is connected to the output? You might be loading it down. Check your signal directly at the output of the 555 with nothing connected to see if you have the correct signal. If so, then you need to isolate it from the load with a little more hardware.
