  In the acoustic system S, the audio data output terminal 19c and the audio data input terminal 911c are electrically connected and the control data output terminal 19d and the control data input in a state where the mobile phone 1 is mounted on the cradle 900. Terminal 911d is electrically connected. In the acoustic system S, the charging terminal 19a and the power supply terminal 911a (not shown in FIG. 11) are electrically connected in a state where the mobile phone 1 is placed on the cradle 900. Each component will be described below.

  The operation key groups 11 and 33 can select a song and specify the volume of the song, and can fast forward or reverse a song being played.

  The CPU 821 outputs control data to the memory 823, the decoder 825, the switching unit 835, the first sound adjustment unit 831, and the second sound adjustment unit 833. As control data, data of a volume setting value for setting the volume of sound emitted from each speaker, data for specifying an output destination such as audio data in the switching unit 835, and a range of sound generated by each speaker The range setting value data for designating can be exemplified.

  Here, the CPU 821 outputs predetermined control data when receiving detection data output from the sensor 827 when it is detected that the mobile phone 1 is placed on the cradle 900. Specifically, the CPU 821 sends the audio data to the switching unit 835, the first sound adjustment unit 831 on the first speaker 800A and the second speaker 800B side, the first table side speaker 910A and the second table side speaker. Control data including an instruction to be output to both the second sound adjustment unit 833 on the 910B side is output.

  Then, the CPU 821 includes a control including an instruction to output the audio data only to the second sound adjustment unit 833 on the first cradle side speaker 910A and the second cradle side speaker 910B to the switching unit 835 after a predetermined time has elapsed. Output data. That is, the CPU 821 causes the switching unit 835 to stop outputting audio data to the first sound adjustment unit 831 on the first speaker 800A and the second speaker 800B side after a predetermined time has elapsed.

  In addition, the CPU 821 reduces the volume of sound emitted from the first speaker 800A and the second speaker 800B as time elapses within a predetermined time, and the first cradle side speaker 910A and the second cradle side. The volume setting value is changed so that the volume of the sound emitted from the speaker 910B increases. Specifically, the CPU 821 decreases the volume setting value output to the first sound adjustment unit 831 and increases the volume setting value output to the second sound adjustment unit 833 over time within a predetermined time. . Thereby, sound emission can be smoothly switched from the first speaker 800A and the second speaker 800B side to the first cradle side speaker 910A and the second cradle side speaker 910B side.

  Here, the upper limit of the volume setting value output to the second sound adjustment unit 833 is set to the volume setting value output to the first sound adjustment unit 831 when the mobile phone 1 is placed on the cradle 900. be able to. In addition, the upper limit of the volume setting value output to the second sound adjustment unit 833 is the sound emitted from the first speaker 800A and the second speaker 800B when the mobile phone 1 is placed on the cradle 900; The volume setting value can be set so that the volume of sound emitted from the first cradle side speaker 910A and the second cradle side speaker 910B is the same.

  Further, the CPU 821 causes the switching unit 835 to output audio data to both the first sound adjustment unit 831 and the second sound adjustment unit 833, and outputs the audio data to the first sound adjustment unit 831 and the second sound adjustment unit 833. The volume setting value can be changed. Specifically, the CPU 821 causes the mobile phone 1 to generate sound from both the first speaker 800A and the second speaker 800B and the first cradle side speaker 910A and the second cradle side speaker 910B. Volume setting values that are the same as or lower than the volume of sound emitted from the first speaker 800A and the second speaker 800B before being placed can be output.

  When the detection data notifying that the mobile phone 1 is separated from the cradle 900 is received from the sensor 827 within a predetermined time, the CPU 821 instructs the switching unit 835 to the first sound adjustment unit 831 even after the predetermined time has elapsed. Can be instructed to continue outputting the audio data. That is, in this case, the CPU 821 continues to emit sound from the first speaker 800A and the second speaker 800B even after a predetermined time has elapsed. Thereby, the stop of sound emission due to the mobile phone 1 being detached from the cradle 900 can be suppressed.

  In addition, when receiving detection data notifying that the mobile phone 1 has been placed on the cradle 900 again from the sensor 927 within a predetermined time, the CPU 821 further passes the predetermined time from the redetection to the switching unit 835. Until the first sound adjustment unit 831 continues to output audio data. That is, the CPU 821 continues sound emission from the first speaker 800A and the second speaker 800B until a predetermined time further elapses after redetection. Thereby, after the state in which the connection of each terminal is uncertain, such as the state in which the mobile phone 1 is shaking, has been cured, the audio data is transmitted to both the first sound adjustment unit 831 and the second sound adjustment unit 833 for a predetermined time. The sound emission can be switched without interrupting the sound.

  The memory 823 stores the audio data of the encoded music. The memory 823 outputs the encoded audio data to the decoder 825 based on an instruction from the CPU 821. The decoder 825 decodes the encoded audio data output from the memory 823 and outputs the decoded audio data to the switching unit 835.

  The switching unit 835 outputs audio data and control data to the first sound adjustment unit 831 and / or the second sound adjustment unit 833 based on an instruction from the CPU 821. In a state where the mobile phone 1 is not placed on the cradle 900, the switching unit 835 causes the first sound adjustment unit 831 to output audio data and the like. Then, in a state where the mobile phone 1 is placed on the cradle 900, the switching unit 835 outputs audio data or the like to the first sound adjustment unit 831 and / or the second sound adjustment unit 833 based on an instruction from the CPU 821. To do. Specifically, the switching unit 835 outputs audio data only from the first speaker 800A and the second speaker 800B (mobile phone 1) side, and outputs audio data from the first speaker 800A and the second speaker 800B ( Both the mobile phone 1) side and the first cradle side speaker 910A and the second cradle side speaker 910B (the cradle 900) side.

  The first sound adjustment unit 831 causes the first speaker 800A and the second speaker 800B to emit a predetermined sound based on the audio data and the control data. Specifically, the first speaker 800 </ b> A is composed of a musical composition based on the audio data with a sound in a range based on a range designation value that designates a range included in the control data at a volume based on a volume setting value included in the control data. And the second speaker 800B emits sound. In addition, when the switching unit 835 outputs audio data only to the second sound adjustment unit 833 after a predetermined time has elapsed, the first sound adjustment unit 831 emits sound from the first speaker 800A and the second speaker 800B. Stop.

  Similarly, the second sound adjustment unit 833 causes the first cradle side speaker 910A and the second cradle side speaker 910B to generate a predetermined sound based on the audio data and the control data. Specifically, the first pedestal is composed of a musical composition based on the audio data with a sound in a range based on a range specification value that specifies a range included in the control data at a volume level based on a volume setting value included in the control data. The side speaker 910A and the second cradle side speaker 910B emit sound. Here, when the switching unit 835 outputs the audio data not only to the first sound adjustment unit 831 but also to the second sound adjustment unit 833, the second sound adjustment unit 833 includes the first cradle side speaker 910A and the second sound adjustment unit 833. A predetermined sound is emitted from the cradle side speaker 910B at a volume based on the volume setting value included in the control data. In addition, when the switching unit 835 outputs the audio data only to the second sound adjustment unit 833 after a predetermined time has elapsed, the second sound adjustment unit 833 includes the first cradle side speaker 910A and the second cradle side speaker. Continue to emit sound from 910B.

  The sensor 827 detects that predetermined power is supplied from the power supply terminal 911a via the charging terminal 19a, and detects that the mobile phone 1 is placed on the cradle 900. The sensor 827 similarly detects that the mobile phone 1 placed on the cradle 900 is separated from the cradle 900. When the sensor 827 detects that the mobile phone 1 is placed on the cradle 900, the sensor 827 outputs detection data to that effect to the CPU 821. In addition, when the sensor 827 detects that the mobile phone 1 is separated from the cradle 900, the sensor 827 outputs detection data to that effect to the CPU 821. As described above, when the CPU 821 receives the detection data output from the sensor 827, the CPU 821 sends an instruction to switch the output destination or a changed volume setting value to the switching unit 835 and the second sound adjustment unit 833. Output control data including.

  Subsequently, the operation of the acoustic system S will be described with reference to FIGS. FIG. 12 is a front view illustrating each aspect of the acoustic system S. FIG. 13 is a flowchart illustrating an aspect of the operation of the acoustic system S. FIG. 14 is a flowchart illustrating another aspect of the operation of the acoustic system S.

An aspect 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 (ST1). Thereby, the music instructed to be reproduced from the first speaker 800A and the second speaker 800B of the mobile phone 1 is emitted by the stereophonic reproduction (ST2).

  Next, reproduction is continued in a state in which the cellular phone 1 is folded to the first closed state shown in FIGS. 5 and 12A (ST3). Specifically, a straight line ZA connecting the first speaker 800A and the second speaker 800B is projected onto a predetermined plane P parallel to the straight line ZA (a plane parallel to the front surface in FIGS. 12A and 12B). The reproduction is continued in a state where one straight line Z1 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. The sound space is formed as a stereophonic reproduction.

  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 (ST4). 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 (ST5). The sensor 827 detects that the mobile phone 1 is placed on the cradle 900 (ST6).

  The CPU 821 instructs the switching unit 835 to switch the output destination of the audio data to the first sound adjusting unit 831 and the second sound adjusting unit 833 (ST7). That is, the CPU 821 emits sound from both the first speaker 800A and the second speaker 800B and the first cradle side speaker 910A and the second cradle side speaker 910B.

  In addition, the CPU 821 sets the first sound adjustment unit 831 and the second sound adjustment unit 833 based on the volume setting value output to the first sound adjustment unit 831 when the mobile phone 1 is placed on the cradle 900. A smaller volume setting value is output (ST8). Specifically, the volume of sound emitted from the first speaker 800A and the second speaker 800B and the first cradle side speaker 910A and the second cradle side speaker 910B is set so that the mobile phone 1 is placed on the cradle 900. When set, the CPU 821 outputs a volume setting value that is less than or equal to the volume of the sound emitted from the first speaker 800A and the second speaker 800B to the first sound adjustment unit 831 and the second sound adjustment unit 833, respectively. .

  The CPU 821 decreases the volume setting value output to the first sound adjustment unit 831 and increases the volume setting value output to the second sound adjustment unit 833 as time elapses within a predetermined time (ST9). That is, the CPU 821 reduces the sound emitted from the first speaker 800A and the second speaker 800B as time elapses within a predetermined time, and at the same time, the first cradle side speaker 910A and the second cradle side speaker 910B. Increase the sound emitted from the.

  Then, after a predetermined time has elapsed, CPU 821 instructs switching unit 835 to set the output destination to only second sound adjustment unit 833 (ST10). Thereby, the sound emission from the first speaker 800A and the second speaker 800B on the mobile phone 1 side is switched to sound emission from the first cradle side speaker 910A and the second cradle side speaker 910B without interruption.

Subsequently, another aspect in the operation of the acoustic system S will be described with reference to FIGS. 12 and 14.
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 (ST11). Thereby, the music instructed to be reproduced from the first speaker 800A and the second speaker 800B of the mobile phone 1 is emitted by the stereophonic reproduction (ST12).

  Next, reproduction is continued in a state in which the cellular phone 1 is folded so as to be in the first closed state shown in FIGS. 5 and 12A (ST13). Specifically, the reproduction is continued in a state where the first straight line Z1 obtained by projecting the straight line ZA connecting the first speaker 800A and the second speaker 800B onto the plane P 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. The sound space is formed as a stereophonic reproduction.

  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 (ST14). 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 (ST15). The sensor 827 detects that the mobile phone 1 is placed on the cradle 900 (ST16).

  The CPU 821 instructs the switching unit 835 to switch the output destination of the audio data to the first sound adjusting unit 831 and the second sound adjusting unit 833 (ST17). That is, the CPU 821 emits sound from both the first speaker 800A and the second speaker 800B and the first cradle side speaker 910A and the second cradle side speaker 910B.

  In addition, the CPU 821 sets the first sound adjustment unit 831 and the second sound adjustment unit 833 based on the volume setting value output to the first sound adjustment unit 831 when the mobile phone 1 is placed on the cradle 900. A smaller volume setting value is output (ST18). Specifically, the volume of sound emitted from the first speaker 800A and the second speaker 800B and the first cradle side speaker 910A and the second cradle side speaker 910B is set so that the mobile phone 1 is placed on the cradle 900. When set, the CPU 821 outputs a volume setting value that is less than or equal to the volume of the sound emitted from the first speaker 800A and the second speaker 800B to the first sound adjustment unit 831 and the second sound adjustment unit 833, respectively. .

  CPU 821 instructs switching unit 835 to continue outputting audio data to first sound adjustment unit 831 when cellular phone 1 is separated from cradle 900 within a predetermined time (ST19). Thereby, sound emission from the first speaker 800A and the second speaker 800B is continued even when the mobile phone 1 is separated from the cradle 900.

  Further, when the sensor 827 detects again that the mobile phone 1 separated from the cradle 900 is placed on the cradle 900 again, that is, the sensor 827 places the mobile phone 1 on the cradle 900 again. If detected, the CPU 821 instructs the switching unit 835 to continue outputting the audio data to the first sound adjustment unit 831 and the second sound adjustment unit 833 for a predetermined time (ST20). In other words, even if a predetermined time elapses when the mobile phone 1 is first placed on the cradle 900, the CPU 821 first continues for a predetermined time after the mobile phone 1 is placed on the cradle 900 again. The switching unit 835 is instructed to output audio data to the sound adjustment unit 831 and the second sound adjustment unit 833.

  Then, after a predetermined time has elapsed, CPU 821 instructs switching unit 835 to use only the second sound adjustment unit 833 as the output destination (ST21). Thereby, the sound emission from the first speaker 800A and the second speaker 800B on the mobile phone 1 side is switched to sound emission from the first cradle side speaker 910A and the second cradle side speaker 910B without interruption.

  According to this embodiment, when the mobile phone 1 is placed on the cradle 900, the cradle 900 is made to emit sound for a predetermined time from both the speaker on the mobile phone 1 side and the speaker on the cradle 900 side. By emitting sound only to the speaker on the side, sound emission can be switched without interrupting the sound. In addition, when the mobile phone 1 is placed on the cradle 900, sound is superimposed and emitted from both the speaker on the mobile phone 1 side and the speaker on the cradle 900 side, so that sound emission can be switched without a sense of incongruity. it can.

  Further, according to the present embodiment, when the mobile phone 1 is placed on the cradle 900, the volume of sound emitted from the speaker on the mobile phone 1 side is reduced as time passes, and the cradle Since the loudness of sound emitted from the speaker on the 900 side is increased, sound emission can be switched more smoothly.

  Further, according to the present embodiment, when the mobile phone 1 is separated from the pedestal within a predetermined time, the sound emission from the speaker on the mobile phone 1 side is continued even after the predetermined time has elapsed, so that the sound emission is stopped. Can be suppressed.

  In addition, according to the present embodiment, when the mobile phone 1 that is separated from the cradle 900 is placed on the cradle 900 again, the mobile phone 1 is further carried for a predetermined time from when the mobile phone 1 is placed on the cradle 900 again. Since sound emission from the speaker on the telephone 1 side is continued, sound emission can be switched without interrupting the sound. In other words, both the first sound adjustment unit 831 and the second sound adjustment unit 833 are further set for a predetermined time after the connection of each terminal is uncertain, such as when the mounted mobile phone 1 is shaking. By outputting audio data, sound emission can be switched without interrupting the sound.

  As mentioned above, although preferred embodiment of this form was described, this invention can be implemented with a various form, without being limited to embodiment mentioned above. In the present embodiment, the switching unit 835 is disposed only on the mobile phone 1 side, but is not limited thereto, and may be configured by the mobile phone 1 and elements disposed on the cradle 900 side. For example, an amplifier that outputs audio data to a speaker on the cradle 900 side and that can switch between outputting and not outputting audio data to the speaker based on an instruction from the CPU 821 is provided on the cradle 900 side in the switching unit 835. It can be further arranged as an element. In this case, it can be configured such that the switching unit 835 always outputs audio data and the amplifier outputs audio data to the speaker on the stage 900 side according to an instruction from the CPU 821.
