    Could be the low speed sound that Toyota added to these models to warn pedestrians that you are in Silent Running mode. It comes from a speaker on the front driver's side and quits when you stop.

    It’s not. because it happens on either low speed or fast speed. And it comes from outside

    More information informs the issue. At any speed I would look at a wheel hub (bearing) first, brakes second.
