Here's the circuit of an amplifier where the speaker is used as a microphone:

And this is my TINA simulation:

1) I'm not even sure I understood the circuit right. Especially, regarding split voltage source.
2) When I check the simulation in TinaTI is gives me these errors:
The .TSC file is here in case you want to use it.
Thank you!

I do not understand these errors, can someone please explain what's wrong with it?- Pin Prim1 of Ideal Transformer TR1 is floating (This node will be grounded)
- Pin Prim1 of Ideal Transformer TR1 is floating (This node will be grounded): Pin 2 of Loud-speaker SP1 is floating (This node will be grounded)
- Pin Prem2 of Ideal Transformer TR1 is floating
- Pin Prem2 of Ideal Transformer TR1 is floating: Pin 1 of Loud-speaker SP1 is floating
The .TSC file is here in case you want to use it.
Thank you!
