Abstract: A vehicle comprises a car seat comprising a seating area and a backrest, wherein the seating area is arranged at a lower end of the backrest, and a low frequency speaker configured to emit sound at frequencies of between 20 Hz and 200 Hz, wherein the backrest comprises a rigid frame, a flexible suspension system, and upholstery, wherein the suspension system is suspended in the frame and covered by the upholstery such that, when an occupant of the vehicle is seated on the car seat, at least a portion of the upholstery is arranged between the suspension system and the occupant. The low frequency speaker is arranged in the backrest and attached to the suspension system, wherein the low frequency speaker is arranged on a backside of the suspension system that faces away from the seating area.

Abstract: A chair includes a seating area and a backrest, wherein the seating area is arranged at a lower end of the backrest, a low frequency speaker configured to emit sound at frequencies of between 20 Hz and 200 Hz, and a coupling mechanism, wherein the coupling mechanism is configured to change between at least two different states, wherein, in a first state, the low frequency speaker is coupled to the chair via at least one acoustical path such that vibrations are transmitted from the low frequency speaker to the chair via each of the at least one acoustical path, wherein the vibrations can be perceived as tactile feedback by a user seated on the chair, and, in a second state, each of the at least one acoustical path is interrupted such that no or almost no vibrations are transmitted from the low frequency speaker to the chair.

Abstract: An audio system and a corresponding method for generating a virtual soundstage in a vehicle interior are described. A speaker array with at least a first and second central speaker is used, which is arranged centrally between two vehicle seats. In addition, pairs of seat speakers are located near the head regions of the occupants. A signal processing unit receives an input signal and controls the speakers. The central speakers are controlled with inverted and time-shifted signals in order to generate zero points in the radiation characteristics. These are directed at the ear regions of the head regions and thus center the perception of the virtual soundstage. The seat speakers create spatial sound envelopes around the head regions. By combining the central speaker array with targeted control and side seat speakers, an optimized seat-position-centered sound reproduction with an immersive sound impression is achieved.

Abstract: An audio system arranged in a listening environment in a vehicle comprises an audio unit configured to output audio signals, a first loudspeaker arranged in a first headrest of the vehicle, a second loudspeaker arranged in the first headrest, a third loudspeaker arranged in the first headrest, and a fourth loudspeaker arranged in the first headrest, wherein each of the first, second, third, and fourth loudspeaker receives the audio signals from the audio unit and is configured to reproduce the audio signals. Each of the first loudspeaker, the second loudspeaker, the third loudspeaker, and the fourth loudspeaker is arranged in predetermined positions within the headrest when a passenger is seated in front of the headrest.

Abstract: A computer-implemented method performed by an audio system including a processor and a plurality of loudspeakers, comprises receiving an audio signal to be output to a listener, obtaining a first Head Related Transfer Function (HRTF) corresponding to a first predefined listening pose of the listener, obtaining a second HRTF corresponding to a second predefined listening pose of the listener, determining, for each of the plurality of loudspeakers a respective loudspeaker signal using the audio signal, the first HRTF, and the second HRTF, and simultaneously outputting, via the plurality of loudspeakers using the loudspeaker signals, a first sound signal for the first predefined listening pose corresponding to the first HRTF and limited to a first predefined spatial zone, and a second sound signal for the second predefined listening pose corresponding to the second HRTF and limited to a second predefined spatial zone different from the first predefined spatial zone.

Abstract: A system and method for generating a virtual soundstage in a listening environment having a compact speaker array centrally positioned in a listening environment. A listener is sitting offset from the speaker array and the virtual soundstage is generated in front of a listener. A signal processing unit is configured to receive an incoming audio signal, to process left and right channel signals of the incoming audio signal to generate a null, and to steer the null toward one ear of a listener thereby generating a virtual sound source that is offset from the center of the listening environment. Virtual sound sources are generated in front of, to the left of, and to the right of the listener.
