hello, attached you will find a few speed feedback loudspeaker arrangements using a Dual Voice Coil (DVC) speaker driver, with one of the two coils being used as speed sensor. For maximizing the speed feedback, the loudspeaker needs to be current driven. The simulation results look interesting. See attached pictures. Can somebody help me refining the simulations, taking into account the electromagnetic cross-coupling effect of the two coils ? Thanks. Steph. Use the .zip at your will.
