I agree, but in this case the only innovation I see is applying a known solution to protect large inductor coils (transformers, motors) to protect smaller, inductor coils (speaker drivers).
Apple can patent their actual model all they want (for example by adding the driven air as a cooling term), but the idea, generally, of building a model to estimate the temperature is prior art.
