Hey guys, I am a Master's Student and I have a simulation project where I need to model a pair of in-ear headphones. I am struggling to get any dimensional/material property data and I would love it if I could get some help.

I chose the JBL T110 earphones but if anyone has details for any other model, I can change. If available, I would like:
1. Drawings of the permanent magnet and voice-coil with diaphragm (or approximate dimensions)
2. Material properties of the diaphragm (or material names, all I can find is that they are made of paper or plastic, nothing more detailed)
3. Magnetic field strength of the permanent magnet, in Tesla (or usually used field strengths in some earphones)

Thank you!
