The speaker doesn't just push out, it pulls in too. The audio signal is alternating current. For parts of the signal which are above 0, the P output device is active, for parts of the signal below 0, the N output device is active.
Actually, the P device is run slightly into the negative (even though it is very inefficient to do so), and the opposite for the N. This minimizes zero-cross distortion.
Thanks. I'm really not trying to be a pest and am just curious. I hope you don't think otherwise with all my silly questions.
Considering that, I've been trying to find information regarding the operation of a voice coil to describe just how electrical current flows through the windings to position the driver to the fixed magnet. I'm not having much success. Can someone either point somewhere, or explain this?
