MOBILE DEVICE WITH AUTOMATIC VOLUME CONTROL

摘要

A mobile device includes a speaker configured to produce output, a proximity sensor configured to generate distance data, an orientation sensor configured to generate orientation data, and a processing circuit. The processing circuit calculates a distance between the mobile device and a region proximate to a user's ear based on the distance data, calculates an angular orientation of the mobile device with respect to the region based on the orientation data, and adjusts the speaker output based on the calculated distance and angular orientation.
