Trademark “Sound Driver”

Princess Caroline Murat has registered the trademark for her “Sound Driver” idea for own, individually played or sung musical themes rising and falling with the speed of electric engines in cars and boats to gently advise arrival towards pedestrians, or just for fun.

Princess Caroline’s 4xGrandmother and direct ancestor, also Princess Caroline Murat had the idea for the first wristwatch in 1805 but was unable to patent it. In 2025 Princess Caroline celebrates her trademark in Paris.
