Abstract

A speaker system comprised of more than one speaker, which utilizes the known characteristics and location of each speaker to enhance low frequency (low (bass) frequency) performance of the system.

First claim

What is claimed is:

1. A device comprising:
at least one computer memory that is not a transitory signal and that comprises instructions executable by at least one processor for:
accessing characteristics of plural speakers having respective locations within a space;
modeling multiple speaker configurations;
determining whether a modeled speaker configuration satisfies at least one low (bass) frequency criterion;
establishing the modeled speaker configuration at least in part by automatically setting speaker parameters including identifying individual speakers using respective network addresses, and/or by outputting a suggested configuration to a user, the suggested configuration including at least one suggested speaker location; and
modeling plural equalization of at least a first to model respective boots of an output of the first speaker at a frequency corresponding to a minimum cone excursion of the first speaker.

2. The device of claim 1 , wherein the instructions are executable for establishing the modeled speaker configuration at least in part by automatically setting speaker parameters.

3. The device of claim 2 , wherein the speaker parameters include equalization.

4. The device of claim 1 , wherein the instructions are executable for establishing the modeled speaker configuration at least in part by outputting a suggested configuration to a user.

5. A device comprising:
at least one computer memory that is not a transitory signal and that comprises instructions executable by at least one processor for:
accessing characteristics of plural speakers having respective locations within a space;
determining whether a modeled speaker configuration satisfies at least one low (bass) frequency criterion:
establishing the modeled speaker configuration at least in part by automatically setting speaker parameters including identifying individual speakers using respective network addresses, and/or by outputting a suggested configuration to a user, the suggested configuration including at least one suggested speaker location, wherein the speaker parameters include equalization; and
responsive to a determination that no modeled speaker equalization combination satisfies the at least one low (bass) frequency criterion, modeling plural candidate speaker locations in the space, and otherwise not modeling plural candidate speaker locations in the space.

6. The device of claim 1 , wherein the instructions are executable for:
receiving at least one test signal from at least one measurement microphone; and
using the test signal to determine a modeled speaker configuration.

7. Method comprising:
accessing characteristics of a multi-speaker system;
modeling multiple speaker configurations of the system;
determining whether a modeled speaker configuration satisfies at least one low (bass) frequency criterion;
establishing the modeled speaker configuration at least in part responsive to a determination that the modeled speaker configuration satisfies the at least one low (bass) frequency criterion, wherein the speaker parameters include equalization; and
responsive to a determination that no modeled speaker equalization combination satisfies the at least one low (bass) frequency criterion, modeling plural candidate speaker locations in the space and otherwise not modeling plural candidate speaker locations in the space.

8. The method of claim 7 , wherein the modeled speaker configuration is established at least in part by automatically setting speaker parameters.

9. The device of claim 1 , comprising the at least one processor.

10. The method of claim 7 , wherein the modeled speaker configuration is established at least in part by outputting a suggested configuration to a user.

11. Method comprising:
accessing characteristics of a multi-speaker system;
modeling multiple speaker configurations of the system;
determining whether a modeled speaker configuration satisfies at least one low (bass) frequency criterion;
establishing the modeled speaker configuration at least in part responsive to a determination that the modeled speaker configuration satisfies the at least one low (bass) frequency criterion; and
modeling plural equalizations of at least a first speaker to model respective boosts of an output of the first speaker at a frequency corresponding to a minimum cone excursion of the first speaker.

12. The method of claim 7 , comprising:
receiving at least one test signal from at least one measurement microphone; and
using the test signal to determine a modeled speaker configuration.

13. System comprising:
at least one computer readable storage medium bearing instruction executable by as processor Which is configured for accessing the computer readable storage medium to execute the instructions to configure the processor for:
controlling a speaker system comprised of more than one speaker;
using characteristics and locations of each speaker to enhance low (bass) frequency performance of the system at least in part by distributing low (bass) frequencies among plural speakers; and
modeling plural equations of at least a speaker to model respective boosts of an output of the first speaker at a frequency corresponding to a minimum cone excursion of the first speaker.

14. The system of claim 13 , wherein the the intructions configure the processor for executing the act of using by configuring the processor for:
accessing characteristics of plural speakers having respective locations within a space;
modeling multiple speaker configurations;
determining whether a modeled speaker configuration satisfies at least one low (bass) frequency criterion; and
establishing the modeled speaker configuration at least in part by automatically setting speaker parameters including identifying individual speakers using respective network addresses, and/or by outputting a suggested configuration to a user, the suggested configuration including at least one suggested speaker location.

15. The system of claim 14 , wherein the modeled speaker configuration is established by the processor when executing the instructions at least in part by automatically setting speaker parameters.

16. The system of claim 15 , wherein the speaker parameters include equalization.

17. The system of claim 14 , wherein the modeled speaker configuration is established by the processor when executing the instructions at least in part by outputting a suggested configuration to a user.
