Shattering Glasses?
I'm designing a system for shattering wine glasses with high intensity sound, but my design doesn't "feel" right to me, and I need somebody to tell me if I've forgotten something important. I need an oscilloscope to measure the resonant frequency of the glass and a frequency generator to produce it. I need stereo speakers and a stereo amplifier powerful enough to generate the sound to break the glass. But how do I correctly get the signal from the frequency generator into the stereo amplifier. Do I need a pre-amp, or do I just wire it straight in? If I need a pre-amp, how do I spec it, on the outputs of the freq generator and the input of the amplifier? What if I'm using a receiver with the pre- amplifier and the amplifier built-in? Can I just use the pre-amp that was intended for the turntable? |
