How is sound converted to vibration on a controller?

An audio-to-haptic algorithm (such as RA2H) analyzes the audio stream in real time and drives the LRA with a matched haptic signal at ~18ms latency.

Can audio-to-haptic run on phones?

Yes — RA2H runs on Android, Windows and RTOS, so the same approach works on phones, controllers and embedded devices.
