Question:

An electromagnetic microphone has a construction similar to that of the speaker shown in Figure 6.7.2, except that there is no applied voltage and the sound waves are incoming rather than outgoing. They exert a force fs on the diaphragm whose mass is m, damping is c, and stiffness is k. Develop a model of the microphone, whose input is fs, and output is the current i in the coil.
