Yes, you can say so.

In fact, there are sensors in all microphones, one of them is the moving coil transducer whose structure principle that is splicing a light metal coil in the elastic diaphragm; Due to the coil is in a field of permanent magnet, as the elastic diaphragm vibrates, the microphone will output electrical signal.

PS: So long as the elastic diaphragm viabrates, the metal coil will generate induction current corresponding with the changing of the magnetic flux; Apart form that, the frequency of induction current is the same as the sound signal.
