You have got things generally correct but what creates the sound is not the coil but the conical diaphragm which is connected to the coil. The coil is constrained in a very powerful magnetic field in a circular slot in a circular permanent magnet. The variation of the audio signal causes variation in the magnetic field of the coil. The reactions between the magnetic field of the coil and the permanent field of the magnet moves the diaphragm and this vibrates creating sound waves.
