摘要： Double-talk detection systems and methods are provided that include a plurality of microphones and array processing to detect when a vehicle occupant is speaking. One or more array processors combine the microphone signals to provide a primary signal and a reference signal. The responses of the primary signal and the reference signal are different in the direction of an occupant location. A comparison of energy content is made between the primary signal and reference signal to selectively indicate double-talk based on the comparison.

The backrest portion includes an enclosure for receiving at least a portion of an acoustic transducer. The vehicle seat also includes an acoustic channel having a first end that is configured to be fitted around a driver of the acoustic transducer in an acoustically sealed configuration, and a second end. The second end is opposite the first end and disposed at a location closer to the seat headrest portion than the seat backrest portion. The acoustic channel is configured to radiate acoustic energy from the acoustic transducer through the second end.

摘要： 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.

摘要： The technology described in this document can be embodied in a headrest for a vehicle-seat, the headrest including a first acoustic assembly and a second acoustic assembly. The first acoustic assembly includes a first set of one or more acoustic transducers, and is configured to radiate acoustic energy from a first portion of the headrest in a first radiation pattern. The second acoustic assembly includes a second set of one or more acoustic transducers, and is configured to radiate acoustic energy from a second portion of the headrest in a second radiation pattern. The first acoustic assembly and the second acoustic assembly are configured such that the first radiation pattern and the second radiation pattern are substantially different from one another, and generate an asymmetric radiation pattern for the headrest.

摘要： An automobile audio system includes a signal processor configured to receive and process audio signals from a source and provide processed audio signals to an amplifier, a first headrest including a headrest speaker and coupled to a driver's seat, a first fixed speaker positioned near a left corner of the vehicle's cabin forward of the headrest, a second fixed speaker positioned near a right corner of the vehicle's cabin forward of the headrest, and a headrest accessory port located in a passenger's seat. The port is configured to connect the audio system to a second headrest speaker. The processor uses a first set of parameters for processing the received audio signals when the first headrest speaker is connected and the second headrest speaker is not connected, and a second set of parameters for processing the received audio signals when both the first and second headrest speaker are connected.
