npub1zdp33shl69xr0uq3x8n5gsjykq9upycwh6nqm02c3f6x0frrn0dq42vqv8 (npub1zdp…vqv8) I think Armature is a fixed magnet. Then when the audio signal flows through the coil, it generates a magnetic field which changes as the music changes. This field then pushes and pulls against the armatures magnetic field, shaking the coil. In this diagram, that movement is transferred to the membrane by that pin you identified. The membrane can shift more air, making the noise louder.
