First, an audio signal is output to the speaker 11 of the portable electronic device 1 (S1). Here, it
is assumed that music data is reproduced. When the plug of the headphone 2 is inserted into the
headphone jack 133 during the reproduction of music data (S2: YES), the control unit 151 refers
to the hard disk drive 148 and confirms the presence or absence of the setting value for the
headphone volume. When the set value of the headphone volume is stored in the hard disk drive
148 (S3: YES), the control unit 151 outputs a control signal to the audio output unit 146 so as to
perform audio output at the set volume. The audio output unit 146 outputs audio to the
headphones 2 at the set volume (S4).
[0058]
In addition, when the set value of the headphone volume is not stored in the hard disk drive 148
(S3: NO), the control unit 151 performs an audio output at the same volume as the volume
output to the speaker 11. Output control signal to The audio output unit 146 outputs audio to
the headphone 2 at the same volume as the speaker 11 (S5).
[0059]
FIG. 14 is a second flowchart showing the operation of the portable electronic device in the
09-05-2019
15
embodiment of the present invention.
[0060]
First, an audio signal is output to the headphones 2 of the portable electronic device 1 (S11).
Here, it is assumed that music data is reproduced. If the plug of the headphone 2 is removed
from the headphone jack 133 during the reproduction of music data (S12: YES), the control unit
151 refers to the hard disk drive 148 and confirms the presence or absence of the setting value
for the speaker volume. When the set value of the speaker volume is stored in the hard disk drive
148 (S13: YES), the control unit 151 outputs a control signal to the audio output unit 146 so as
to perform audio output at the set volume. The voice output unit 146 outputs voice to the
speaker 11 at the set volume (S14).
[0061]
When the speaker volume of the setting value is lower than the headphone volume and the user
operates any switch after switching the audio output to the speaker 11 (S15: YES), the controller
151 fades in. At the speaker output, the volume of the speaker 11 is increased to the same
volume as the headphone volume (S16). When the user does not perform the switch operation,
the voice is output to the speaker 11 at the set volume (S15: NO).
[0062]
Further, when the set value of the speaker volume is not stored in the hard disk drive 148 (S13:
NO), the control unit 151 confirms the presence or absence of the fade-in speaker output setting
in the hard disk drive 148. When the setting of the fade-in speaker output is stored in the hard
disk drive 148 (S17: YES), the volume of the speaker 11 is increased by the fade-in speaker
output to the same volume as the headphone volume (S16).
[0063]
09-05-2019
16
In addition, when the setting of fade-in speaker output is not stored in the hard disk drive 148
(S17: NO), the control unit 151 outputs a control signal to the audio output unit 146 so as to
perform audio output at the same volume as the headphone volume. Do. The audio output unit
146 outputs audio to the speaker 11 at the same volume as the headphone volume (S18).
[0064]
(Effects of the Embodiment of the Present Invention) According to the embodiment of the present
