Electronic apparatus equipped with function for notifying acceptance of operation, method of controlling electronic apparatus, and storage medium

Abstract

An electronic apparatus capable of reducing a time lag between an operation on an operation section and notification of acceptance of the operation. An audio codec section and a speaker perform notification indicating reception of the operation according to the operation performed on the operation section. A PLL circuit supplies the audio codec section and the speaker with a clock signal for causing the audio codec section and the speaker to operate. A system controller detects an approach of a finger for operating the operation section, to the operation section. Further, the system controller starts the PLL circuit or increases a clock frequency supplied from the PLL circuit, when the system controller detects that the distance between the finger and the operation section has become equal to or smaller than a first distance.
