Abstract

An acoustic zoning system for a vehicle includes one or more speakers mounted in the vehicle, and a zoning control module that establishing one or more smartphone usage zones in the vehicle. The zoning control module includes a smartphone detection module operable to detect an audible interaction with a smartphone of at least one of a plurality of occupants of the vehicle, and a speaker control module operable to control at least one of the one or more speakers to substantially acoustically isolate the one of the plurality of occupants from another of the plurality of occupants of the vehicle.

Claims

1. An acoustic zoning system for a vehicle comprising:

one or more speakers mounted in the vehicle; and

a zoning control module for establishing one or more smartphone usage zones in the vehicle, the zoning control module comprising;

a smartphone detection module operable to detect an audible interaction with a smartphone of at least one of a plurality of occupants of the vehicle; and

a speaker control module operable to control at least one of the one or more speakers to substantially acoustically isolate the one of the plurality of occupants from others of the plurality of occupants of the vehicle.

2. The acoustic zoning system according to claim 1, further comprising:

a microphone arranged in the vehicle for receiving audio signals.

3. The acoustic zoning system according to claim 2, wherein the zoning control module includes a microphone control module operable to filter audio passing into the microphone.

4. The acoustic zoning system according to claim 2, wherein the smartphone detection module is operatively connected to the microphone, the smartphone detection module being operable to identify a smartphone conversation based on audio signals received at the microphone.

5. The acoustic zoning system according to claim 2, further comprising:

a pairing system operable to pair a smartphone with one or more vehicle systems, the smartphone detection module being operably coupled with the pairing system.

6. The acoustic zoning system according to claim 5, wherein the microphone forms part of a smartphone positioned in the vehicle.

7. A method of establishing smartphone usage zones in a vehicle comprising:

detecting use of a smartphone in the vehicle;

determining a location of the smartphone in the vehicle;

defining a smartphone usage zone at the location of the smartphone; and

controlling one or more speakers in the vehicle to substantially confine audible interactions with the smartphone to the smartphone usage zone.

8. The method of claim 7, further comprising:

controlling the one or more speakers to substantially limit exposure of acoustic emissions from other occupant zones passing into the smartphone usage zone.

9. The method of claim 7, wherein detecting use of the smartphone includes capturing an image smartphone usage.

10. The method of claim 7, wherein detecting use of the smartphone includes sensing smartphone usage through a vehicle-smartphone link.

11. The method of claim 7, further comprising:

attenuating audible signals from the smartphone usage zone passing towards a driver'"'"'s zone of the vehicle.

12. A computer program product for acoustically zoning a vehicle based on smartphone usage, the computer program product comprising a non-transitory computer readable storage medium having program instructions embodied therewith, the program instructions being executable by a computer processor to cause the computer processor to:

detect use of a smartphone in the vehicle;

determine a location of the smartphone in the vehicle;

define a smartphone usage zone at the location of the smartphone; and

control one or more speakers in the vehicle to substantially confine audible interactions with the smartphone to the smartphone usage zone.

13. The computer program product of claim 12, wherein the program instructions are executable by the computer processor to cause the computer processor to control the one or more speakers to substantially limit exposure of acoustic emissions from other occupant zones passing into the smartphone usage zone.

14. The computer program product of claim 12, wherein the program instructions are executable by the computer processor to cause the computer processor to capture an image of smartphone usage when detecting the use of the smartphone.

15. The computer program product of claim 12, wherein the program instructions are executable by the computer processor to cause the computer processor to filter audible signals from other occupant zones passing into a microphone of the smartphone.
