  • Patent number: 10257613
    Abstract: A signal input module receives at least one of an entertainment audio signal and a telephony audio signal from vehicle sound circuitry. A level control module executes gain level control logic to balance the entertainment audio signal and a telephony audio signal according to a ratio. A gain control signal is applied to at least one of the entertainment audio signal and the telephony audio signal. A routing module mixes the entertainment audio signal and the telephony audio signal and routes the mixed signal to an output channel associated with a speaker.

  • Patent number: 9602948
    Abstract: A motor vehicle audio system, and a method of operating such a system. There is at least one rear far-field speaker that is located behind a front seat of the motor vehicle, and at least one near-field speaker located in front of the far-field speaker and close to an intended position of a listener's head. There is an audio signal processor configured to detect when the rear far-field speaker is shut off while the near-field speaker remains on, and in response automatically increase the output energy of the near-field speaker.

  • Patent number: 8031880
    Abstract: A signal processor for use in a vehicle audio system provides multiple operating modes. A first mode provides substantially equal total sound pressure levels at each seating location. A first equalization pattern provides a substantially similar frequency response at each of the seating locations, and a first balance configuration provides substantially similar balance patterns at each of the seating locations. A second mode provides greater sound pressure levels at a first seating location than at other seating locations. A second equalization pattern results in a frequency response at the first seating location that is substantially smoother than the frequency responses at other seating locations, and a second balance configuration results in the balance pattern at the first seating location being substantially more balanced than the balance patterns at other seating locations.

  • Patent number: 7653203
    Abstract: A surround audio system for a vehicle with a plurality of operating modes. The vehicle includes seating locations. The audio system includes a plurality of input channels including surround channels. The audio system further includes a plurality of operating modes. A first operating mode is characterized by substantially equal perceived loudnesses at each of said seating locations, an equalization pattern developed by weighting frequency responses at each of said seating locations substantially equally, and a balance pattern developed by weighting sound pressure level measurements at each of said seating locations substantially equally.

  • Patent number: 7483539
    Abstract: The invention features a dual-mode audio system for an automobile which in one mode is configured for play while the doors to the automobile are closed, and in a second mode, is configured for play while a door, such as a tailgate, is opened. Additionally, the invention also features a battery monitor which monitors the operating condition of the battery and may estimate the energy capacity of the battery. The system may also take power conservation measures if the system determines that the engine is not running or the operating condition of the batter reaches a predetermined state. The invention also features a remote control integrated within a key fob for controlling the audio system. The invention features various orientations for mounting a pair of loudspeakers within an automobile which directly radiate sound out of a rear opening of the automobile.
