Abstract
What is disclosed is a loudspeaker reproduction system for a vehicle having a first loudspeaker array and a second loudspeaker array. The first loudspeaker array is configured to generate a first stereo or virtual multi-channel sound field, wherein the first loudspeaker array is aligned towards a driver position of the vehicle. The second loudspeaker array is configured to generate a second stereo or virtual multi-channel sound field, wherein the second loudspeaker array is aligned towards a front passenger position of the vehicle.
Claims15
A loudspeaker reproduction system for a vehicle, the loudspeaker reproduction system comprising:
- a first loudspeaker array configured to generate a first stereo or virtual multi-channel sound field, wherein the first loudspeaker array is aligned towards a driver position of the vehicle;
- and
- a second loudspeaker array configured to generate a second stereo or virtual multi-channel sound field, wherein the second loudspeaker array is aligned towards a front passenger position of the vehicle,
- wherein the first loudspeaker array and the second loudspeaker array each comprise exactly two loudspeakers;
- and
- wherein the loudspeaker reproduction system is configured
- to reproduce one stereo signal using the first loudspeaker array and the second loudspeaker array, wherein the two loudspeakers of the first loudspeaker array are used to reproduce right and left channels of the stereo signal, respectively, wherein the two loudspeakers of the second loudspeaker array are used to reproduce right and left channels of the same stereo signal, respectively;
- or to reproduce one virtual multi-channel signal using the first loudspeaker array and the second loudspeaker array, wherein the loudspeaker reproduction system is configured to convert the virtual multi-channel signal in a two channel signal and to reproduce the two channel signal using the first loudspeaker array and the second loudspeaker array, wherein the two loudspeakers of the first loudspeaker array are used to reproduce right and left channels of the two channel signal, respectively, wherein the two loudspeakers of the second loudspeaker array are used to reproduce right and left channels of the same two channel signal, respectively.

A method, comprising:
- generating a first stereo or virtual multi-channel sound field with a first loudspeaker array aligned towards a driver position of a vehicle;
- and
- generating a second stereo or virtual multi-channel sound field with a second loudspeaker array aligned towards a front passenger position of the vehicle;
- wherein the first loudspeaker array and the second loudspeaker array each comprise exactly two loudspeakers;
- and
- wherein generating the first stereo or virtual multi-channel sound field and generating the second stereo or virtual multi-channel sound field comprises
- reproducing one stereo signal using the first loudspeaker array and the second loudspeaker array, wherein the two loudspeakers of the first loudspeaker array are used to reproduce right and left channels of the stereo signal, respectively, wherein the two loudspeakers of the second loudspeaker array are used to reproduce right and left channels of the same stereo, respectively;
- or reproducing one virtual multi-channel signal using the first loudspeaker array and the second loudspeaker array and converting the virtual multi-channel signal in a two channel signal and reproducing the two channel signal using the first loudspeaker array and the second loudspeaker array, wherein the two loudspeakers of the first loudspeaker array are used to reproduce right and left channels of the two channel signal, respectively, wherein the two loudspeakers of the second loudspeaker array are used to reproduce right and left channels of the same two channel signal, respectively.

A non-transitory digital storage medium having stored thereon a computer program for performing a method, comprising:
- generating a first stereo or virtual multi-channel sound field with a first loudspeaker array aligned towards a driver position of a vehicle;
- and
- generating a second stereo or virtual multi-channel sound field with a second loudspeaker array aligned towards a front passenger position of the vehicle;
- wherein the first loudspeaker array and the second loudspeaker array each comprise exactly two loudspeakers;
- and
- wherein generating the first stereo or virtual multi-channel sound field and generating the second stereo or virtual multi-channel sound field comprises
- reproducing one stereo signal using the first loudspeaker array and the second loudspeaker array, wherein the two loudspeakers of the first loudspeaker array are used to reproduce right and left channels of the stereo signal, respectively, wherein the two loudspeakers of the second loudspeaker array are used to reproduce right and left channels of the same stereo, respectively;
- or reproducing one virtual multi-channel signal using the first loudspeaker array and the second loudspeaker array and converting the virtual multi-channel signal in a two channel signal and reproducing the two channel signal using the first loudspeaker array and the second loudspeaker array, wherein the two loudspeakers of the first loudspeaker array are used to reproduce right and left channels of the two channel signal, respectively, wherein the two loudspeakers of the second loudspeaker array are used to reproduce right and left channels of the same two channel signal, respectively,
- when said computer program is run by a computer.
