US Patent 10150425 Vehicle speaker systems and methods

Vehicle speaker systems described herein enable different people to simultaneously hear different sounds while traveling in the same vehicle (without using headphones). This revolutionary result is based on novel speaker configurations and uses. Some vehicle audio systems include a first speaker system located above a first seat of a vehicle and configured to emit a first sound based on a first audio file. Vehicle audio systems can also include a second speaker system coupled to the vehicle and configured to emit a second sound based on a second audio file that is unrelated to the first audio file while the first speaker system emits the first sound.
