Abstract:
A system and method for performing speaker load diagnostics. A digital signal processor generates a diagnostic tone that is provided to the speaker. The diagnostic tone is generated using an oscillator internal to the digital signal processor. The digital signal processor receives current and voltage data from the speaker based on the diagnostic tone, and processes the current and voltage data to determine whether a fault condition exists in the speaker.
