US Patent 10313795 Vehicle audio system

A method for generating sound by one or more sound panels in a vehicle, and a sound system are provided. The method includes receiving, by an acoustic exciter coupled to one of the one or more sound panels, a first audio signal. The first audio signal includes a first frequency range. Each of the sound panels is formed of a material having a respective flexural modulus. The method further includes generating, by each of the sound panels, a sound signal comprising a respective range of sound pressure vibrations dependent on the flexural modulus of the sound panel, variations of dimensions of the sound panel, and the first audio signal received by the acoustic exciter.
