In Reply to: RE: "Mechanical movement dissipates the energy as heat." posted by geoffkait on August 27, 2007 at 02:52:25:
you are such a strong believer in the Beltist explanations. And my thanks to Rick for carrying on.
When you apply an electrical current to a quartz oscillator, what do you think happens? The quartz is essentially electrically non conductive. The field emanating from the wire creates an oscillation (mechanical) in the quartz crystal. The piezo effect does not only work in one direction with mechanical pressure effecting a voltage change, and the possibility of a reversal can not occur.
So therefore the analysis is simple emf fields create a mechanical movement in a piece of quartz and, if that crystal is allowed to move, that energy is dissipated as heat by the motion of the crystal. Frankly I don't know where you got the acoustical energy part, because I frankly do not remember ever stating that.
I've actually spoken to a couple of PHD's and done some minor research into the subject, nothing extensive, but a simple search through Google will probably yield similar findings.
