Hey i know someone has asked this but can you use dc current for a loudspeaker? If you have a split ring commutator doesent that create an ac effect?

It's possible, although you'll need to add all this random crap to the loudspeaker.

Your only examining a part of the loudspeaker anyway, just say it needs AC.

Most books i have used have focused on the motor effect and how the voice coil and the external magnetic field affects the volume and pitch. This qsn is usually about 4marks the most it can give is 5marks.
