In the design of a loudspeaker, one intuitively seeks a critically damped alignment. We must consider the electrical resistance of the coil, magnetic field strength, mechanical resistance, mechanical compliance, and mass (diaphragm + acoustic load) of the system.
The electrical resistance, magnetic field strength, and mass of the system are easy to calculate and verify. The mechanical resistance and compliance are more difficult.
If the design uses an acoustic suspension (ie enclosure), we must consider the compliance and resistance of the air within the enclosure.
I believe the linearity of the compliance of the air can be calculated from the derivative of PV=nRT.
However, I'm unsure how to calculate the resistance (viscous damping, correct me if I'm wrong) of the air within the enclosure.
Thanks,
