monaural sound emission based on an instruction from the CPU 821. As a result, the sound
emission state from the first speaker 800A and the second speaker 800B is changed from
stereophonic sound emission to monaural sound emission (ST108).
[0103]
The second sound adjustment unit 833 starts stereophonic sound emission from the first speaker
800A and the second speaker 800B on the mobile phone 1 side based on an instruction from the
CPU 821. Thereby, stereophonic sound emission is started from the first speaker 800A and the
second speaker 800B (ST109).
[0104]

straight line ZB onto the plane P in the state where the mobile phone 1 is placed on the stand
900 in this manner. 2 orthogonal to the straight line Z2.
[0111]
By placing the mobile phone 1 on the stand 900, the charging terminal group 19 and the feeding
terminal group 911 are electrically connected (ST205). Then, sensor 827 detects that mobile
phone 1 has been placed on cradle 900 (ST 206).
[0112]
The CPU 821 instructs the switching unit 835 to set the output destination of the audio data to
both the first sound adjusting unit 831 and the second sound adjusting unit 833. Furthermore,
the CPU 821 instructs the first sound adjustment unit 831 to change from stereophonic sound
emission to monaural sound emission, and instructs the second sound adjustment unit 833 to
start stereophonic sound emission ( ST 207).
[0113]
The first sound adjusting unit 831 changes the sound emission state from the first speaker 800A
and the second speaker 800B on the mobile phone 1 side from stereophonic sound emission to
10-04-2019
33
monaural sound emission based on an instruction from the CPU 821. As a result, the sound
emission state of the first speaker 800A and the second speaker 800B is changed from
stereophonic sound emission to monaural sound emission (ST208).
[0114]
The second sound adjustment unit 833 starts stereophonic sound emission from the first speaker
800A and the second speaker 800B on the mobile phone 1 side based on an instruction from the
CPU 821. Thereby, stereophonic sound emission is started from the first speaker 800A and the
second speaker 800B (ST209).
[0115]
Then, after the predetermined time has elapsed, the CPU 821 instructs the first sound adjusting
unit 831 to emit the sound in which the low range is emphasized (ST210).
[0116]
The first sound adjusting unit 831 processes the audio data so that the bass range is enhanced
based on the instruction from the CPU 821, and emits the voice in which the bass range is
enhanced from the first speaker 800A and the second speaker 800B. Let

second speaker 800B of the mobile phone 1 is reproduced by sound emission (ST302).
[0123]
Next, stereophonic sound emission is continued in a state where the cellular telephone device 1
is in the first closed state shown in FIGS. 5 and 12A (ST 303). Specifically, stereophonic sound
emission continues in a state in which the first straight line Z1 connecting the first speaker 800A
and the second speaker 800B is parallel to the horizontal direction ZX. In this state, the sound of
the first channel emitted from the first speaker 800A is emitted to the outside from the first
speaker hole 810A, and the sound of the second channel from the second speaker 800B is
emitted to the outside from the second speaker hole 810B. An acoustic space is formed as sound
and as stereophonic sound emission.

side is stopped (ST310).
[0130]
Further, based on an instruction from the CPU 821, the second sound adjusting unit 833 changes
the sound emission from the first cradle side speaker 910A and the second cradle side speaker
910B from monaural sound emission to stereophonic sound emission. The sound emission state
from the first cradle side speaker 910A and the second cradle side speaker 910B is changed
from monaural sound emission to stereophonic sound emission (ST311). As a result,
stereophonic sound emission from the first speaker 800A and the second speaker 800B on the
mobile phone 1 side is switched to stereophonic sound emission from the first cradle side
speaker 910A and the second cradle side speaker 910B.
