Electronic apparatus that allows speaker volume control based on surrounding sound volume and method of speaker volume control

When power is turned on, a speaker volume control section (141) obtains the volume of surrounding sound from a microphone (191) and then determines the output volume of a speaker (192) from the volume of surrounding sound. The speaker volume control section (141) then displays the value of the output volume of the speaker (192) thus determined on an LCD (15). After that, the speaker volume control section (141) monitors whether or not an operation of changing the speaker volume is performed and, when such an operation is not performed for a predetermined period of time, presents the determined speaker volume to a sound controller (19). When an operation of changing the speaker volume is performed, the speaker volume control section (141) presents a volume specified by the user to the sound controller (19).
