Not really Epilot. A common speaker is a single transducer and can transmit energy from about 30hz all the way up to and past 20khz. I'm not sure why you find the multiple frequency concept so hard to understand. In order to understand anything on the frequency domain it has to be integrated over time. The number of samples and the length of time over which they're taken determine the ability to perceive difference in frequencies. It's easiest to understand in that if you have only one sample (5 volts) you have NO reference to base a frequency off of. If you have two samples over time, say 5 volts and then one second later 1 volt you then have a reference to base a possible frequency off of. You need to read up on basic quantization. Even an 'analog' circuit has the same limitations.
