Audio power management
First Claim
Patent Images
1. A method for controlling the power consumption of an audio system of a computer, comprising:
- monitoring a parameter that is unrelated to the audio system operation and is indicative of a power conservation opportunity associated with power being delivered to the computer,triggering an audio power management event in response to the parameter, andaltering the low frequency spectral power components of the audio system in a manner that reduces the power consumption of the audio system while continuing to provide intelligible audio output.

Abstract
Power consumption of an audio system of a computer is controlled, in response to an audio power management event, by altering the operation of the audio system in a manner that changes the power consumption of the audio system.

14. Audio power management apparatus, comprising:
-
an audio system; and an audio power manager coupled to the audio system, where the audio power manager monitors a parameter that is unrelated to the audio system operation and is indicative of a power conservation opportunity associated with power being delivered to the computer, and alters the low frequency spectral power components of the audio system in response to an audio power management event triggered in response to the parameter in a manner that reduces the power consumption of the audio system while continuing to provide intelligible audio output. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29)

30. A computer system comprising:
-
a microprocessor; an audio system coupled to the microprocessor; and an audio power manager coupled to the audio system, where the audio power manager monitors a parameter that is unrelated to the audio system operation and is indicative of a power conservation opportunity associated with power being delivered to the computer, and alters the low frequency spectral power components of the audio system in response to an audio power management event triggered in response to the parameter in a manner that reduces the power consumption of the audio system while continuing to provide intelligible audio output.
