I've always been fascinated by technology, and by the way technology has come so far so quickly. But one simplicity that has always fascinated me even more is how a simple cone and magnet can produce an infinite array of timbre.
If I play an oboe it sounds like an oboe. No matter how much I might change the shape and design of the oboe, it always sounds like an oboe, because I'm still using just the two reeds to blow through.
The speaker is the same, it only always has the cone and magnet.
How then can it sound like a trumpet one moment, and by a simple electronic signal change, sound like a xylophone, or a gong, or a fiddle? How does this happen? Does anyone know? Or is it just one of those mysteries of science? I know it has something to do with waves, but I don't see how the cone is capable of producing certain vibrations.
