Automatic volume reduction

摘要

Systems and methods of controlling output volume in mobile devices may include an apparatus having logic to detect a limited power delivery condition of a battery of a mobile platform. The logic may also transmit a hardware alert to an audio controller of the mobile platform in response to the limited power delivery condition, wherein the hardware alert is to instruct the audio controller to conduct a speaker volume reduction to an audible level. In one example, the logic enables the use of one or more high power speakers such as stereo integrated hands free speakers in the mobile device.

主权项

1. A mobile platform comprising:
an integrated hands free speaker module, wherein the integrated hands free speaker module is integral with the mobile platform; an audio controller coupled to the integrated hands free speaker module; a battery; a processor; and logic coupled to the processor, the battery, and the audio controller, the logic to,
detect a limited power delivery condition of the battery while audio content is being output via the integrated hands free speaker module,transmit a hardware alert to the audio controller in response to the limited power delivery condition, wherein the hardware alert is to instruct the audio controller to conduct a speaker volume reduction with respect to the integrated hands free speaker module, and wherein the speaker volume reduction is to cause an audible level of the audio content being output to be reduced to decrease load on the battery from a first load level while the audio content is being output to a second load level while the audio content is being output, andtransmit an interrupt to the processor based on the speaker volume reduction, wherein the processor is to conduct one or more of an additional speaker volume reduction and a speaker volume increase based on a platform power state in response to the interrupt.
