I am looking for equations which would describe sound that a speaker produces.
If I understood the principle how a speaker works correctly, there are a permanent magnet and an electromagnet.
As alternate current flows trough a wire, the poles of electromagent constantly swich places. When current flows in one direction, the magnet repels the electromagnet, when the current flows in another direction, the magnet atttracts the electromagnet, so the electromagnet oscillates.
The frequency at which it oscillates probably depends only on the frequency of the signal, but what the amplitude of the sound (loudness) depends on? Does anyone know any equations with explanations?
(if I am wrong about anything here please tell me so)
