Abstract

The aspects disclosed herein are related to providing a stereoscopic audio environment that is based on speaker position and/or orientation. Once the speaker (or groups of speakers) are identified by the above-described techniques, the audio signal uniquely delivered to each of the speakers may be customized to produce an optimal sound environment.

Claims

1. A system for producing a stereoscopic sound, comprising:

a signal processor situated at a centralized location in an installation room;

at least one loudspeaker, the at least one loudspeaker being arranged at a distance from the centralized location,

wherein

the at least one loudspeaker is configured receive an audio signal and data from the signal processor,

the signal processor is configured to;

determine a position and orientation of the at least one loudspeaker, and

generate the data to be communicated with the audio signal for the at least one loundspeaker based on the determined position and the determined orientation, and

communicate the data and the audio signal to the at least one loudspeaker.

2. The system according to claim 1, wherein the signal processor is further configured to determine the position and orientation automatically.

3. The system according to claim 1, wherein the signal processor as well as the at least one loudspeaker are arranged within a system of coordinates with an origin of coordinate being defined as the centralized location.

4. The system according to claim 1, wherein the signal processor and the at least one loudspeaker are connected to each other wirelessly.

5. The system according to one of claims 1, further comprising

at least two or more loudspeakers, the at least two or more loudspeakers being configured to receive the audio signal and a unique data signal, wherein

the signal processor is further configured to:

determine a position and orientation for each of the at least two or more loudspeakers, and

generate the unique data to be communicated with the audio signal for each of the at least two or more loudspeakers based on the determined position and the determined orientation, and

communicate the unique data and the audio signal to the at least two or more loudspeakers.

9. The system according to claim 1, wherein the signal processor and the at least one loudspeaker are connected to each other wirelessly.

10. The system according to one of claims 1, further comprising

at least two or more loudspeakers, the at least two or more loudspeakers being configured to receive an unique audio signals, wherein

the signal processor is further configured to:

determine a position and orientation for each of the at least two or more loudspeakers, and

generate a unique audio signal for each of the at least two or more loudspeakers based on the determined position and the determined orientation, and

communicate the audio signal to the at least two or more loudspeakers.

11. The system according to claim 5, wherein the unique data includes the determined position and the determined orientation.

12. The system according to claim 11, wherein each of the at least two or more loudspeakers includes a unique signal processor, and the unique signal processor is configured to modify the audio signal based on the received determined position and the determined orientation.

13. The system according to claim 5, wherein the signal processor is implemented in a head unit of a vehicle.

14. The system according to claim 5, wherein the signal processor employs an automatic technique to perform the determination of position and orientation.

15. The system according to claim 10, wherein the signal processor employs an automatic technique to perform the determination of position and orientation.

16. The system according to claim 1, wherein the audio signal is object-based.

6. A system for producing a stereoscopic sound, comprising:

a signal processor situated at a centralized location in an installation room;

at least one loudspeaker, the at least one loudspeaker being arranged at a distance from the centralized location,

wherein

the at least one loudspeaker is configured receive an audio signal the signal processor,

the signal processor is configured to;

determine a position and orientation of the at least one loudspeaker, and

generate the audio signal for the at least one loundspeaker based on the determined position and the determined orientation, and

communicate the audio signal to the at least one loudspeaker.

7. The system according to claim 6, wherein the signal processor is further configured to determine the position and orientation automatically.

8. The system according to claim 6, wherein the signal processor as well as the at least one loudspeaker are arranged within a system of coordinates with an origin of coordinate being defined as the centralized location.

17. The system according to claim 6, wherein the audio signal is object-based.
