  The CPU 821 instructs the switching unit 835 to output the audio data to both the first sound adjustment unit 831 and the second sound adjustment 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 ( ST207).

  The first sound adjustment 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 monaural sound emission based on an instruction from the CPU 821. Thereby, the sound emission state from first speaker 800A and second speaker 800B is changed from stereophonic sound emission to monaural sound emission (ST208).

  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 first speaker 800A and second speaker 800B (ST209).

  Then, after a predetermined time has elapsed, the CPU 821 instructs the first sound adjustment unit 831 to emit a sound in which the low frequency range is emphasized (ST210).

  Based on the instruction from the CPU 821, the first sound adjustment unit 831 processes the audio data so that the low frequency range is emphasized, and emits the audio with the low frequency range emphasized from the first speaker 800A and the second speaker 800B. Let The sound in which the low frequency range is emphasized is emitted from the first speaker 800A and the second speaker 800B. Thereby, the stereophonic sound emission from the first speaker 800A and the second speaker 800B on the mobile phone 1 side is switched to the stereophonic sound emission from the first cradle side speaker 910A and the second cradle side speaker 910B.

  According to the other embodiments described above, when the mobile phone 1 is placed on the cradle 900, the sound emitted by the speaker on the mobile phone 1 side is switched to the sound emitted by the speaker on the cradle 900 side, and the mobile phone 1 By controlling so that the stereophonic sound is not simultaneously emitted from the side speaker and the 900th side speaker, it is possible to suppress deterioration of the acoustic space and sound quality when sound emission is switched.

  According to the other embodiments described above, since there are few steps for switching the stereophonic sound emission on the mobile phone 1 side to the stereophonic sound emission on the stage 900 side, the deterioration of the sound space and the sound quality are suppressed. Switching can be done in a short time.

  Moreover, according to other embodiment mentioned above, since the sound of the low frequency range with a low directivity is emitted from the speaker by the side of the mobile telephone 1, the sound quality in acoustic space can be improved.

  Further, according to the other embodiment described above, the low-frequency sound output from the first speaker 800A on the mobile phone 1 side is emitted from the external space via the space portion 950 formed in the cradle 900. Therefore, the woofer effect can be obtained and the sound quality in the acoustic space can be further improved.

  Specifically, as shown in FIGS. 12A and 12B, the space 950 includes a first opening 951 formed in the placement surface 902 and a second opening 952 formed in the bottom surface 903. It is formed to connect. The space portion 950 functions as a resonance tube. The first opening 951 is formed at a position close to the first speaker hole 810A in a state where the mobile phone 1 is placed. The second opening 952 is formed at a predetermined position on the bottom surface 903. Here, the position of the second opening 952 is not particularly limited as long as it is exposed to the external space, and may be formed on the side surface or the back surface. When the music is played with the mobile phone 1 placed on the placement unit 901, the sound emitted from the first speaker 800A is emitted from the first speaker hole 810A, and the emitted sound is emitted. Is transmitted to the space 950 through the first opening 951. The sound propagated to the space portion 950 is emitted from the second opening 953 to the external space while resonating.

Other aspects in the operation of the acoustic system S will be described with reference to FIGS.
First, in the state shown in FIG. 2, a predetermined music is selected from the music list displayed on the display 30 by the operation key group 11, and reproduction is instructed (ST301). Thereby, the music instructed to be reproduced from the first speaker 800A and the second speaker 800B of the mobile phone 1 is reproduced with stereophonic sound emission (ST302).

  Next, stereophonic sound emission is continued in a state in which the cellular phone 1 is folded to the first closed state shown in FIGS. 5 and 12A (ST303). Specifically, stereophonic sound emission is continued in a state where 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. Sound space is formed as a stereophonic sound emission.

  Subsequently, as shown in FIG. 12B, the mobile phone 1 is placed on the cradle 900 in a horizontal direction so that the first straight line is parallel to the vertical direction ZY (ST304). Thus, in a state where the mobile phone 1 is placed on the cradle 900, the first straight line Z1 is orthogonal to the second straight line Z2 obtained by projecting the straight line ZB onto the plane P.

  When mobile phone 1 is placed on cradle 900, charging terminal group 19 and power supply terminal group 911 are electrically connected (ST305). The sensor 827 detects that the mobile phone 1 is placed on the cradle 900 (ST306).

  The CPU 821 instructs the switching unit 835 to output the audio data to both the first sound adjustment unit 831 and the second sound adjustment unit 833. Furthermore, CPU 821 instructs second sound adjustment unit 833 to start monaural sound emission (ST307). Here, since the first sound adjusting unit 831 is not instructed to change the sound emission state, the stereophonic sound emission is continued in the first speaker 800A and the second speaker 800B on the mobile phone 2 side.

  The second sound adjusting unit 833 starts monaural sound emission from the first cradle side speaker 910A and the second cradle side speaker 910B on the cradle 900 side based on an instruction from the CPU 821. Thereby, monaural sound emission is started from the first cradle side speaker 910A and the second cradle side speaker 910B (ST308).

  Then, after a predetermined time has elapsed, the CPU 821 instructs the switching unit 835 to output only the second sound adjustment unit 833 to the audio data. Furthermore, CPU 821 instructs second sound adjustment section 833 to change the sound emission state from monaural sound emission to stereophonic sound emission (ST309).

  The switching unit 835 changes the output destination of the audio data to only the second sound adjustment unit 833 based on an instruction from the CPU 821. Thereby, stereophonic sound emission from the first speaker 800A and the second speaker 800B on the mobile phone 1 side is stopped (ST310).

  Further, the second sound adjustment unit 833 changes the sound emission from the first cradle side speaker 910A and the second cradle side speaker 910B from monaural sound to stereophonic sound based on an instruction from the CPU 821. 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). Thereby, the stereophonic sound emission from the first speaker 800A and the second speaker 800B on the mobile phone 1 side is switched to the stereophonic sound emission from the first cradle side speaker 910A and the second cradle side speaker 910B.

  According to the present embodiment, when the mobile phone 1 is placed on the cradle 900, the sound emission by the speaker on the mobile phone 1 side is switched to the sound emission by the speaker on the cradle 900 side, and the speaker on the mobile phone 1 side is switched. However, by controlling so that the stereophonic sound is not simultaneously emitted from the speaker on the 900th side, it is possible to suppress deterioration of the sound space and sound quality when sound emission is switched.
