When the microcomputer 22 of the second smartphone 21 receives the ring tone file transmitted from the server 11, the microcomputer 22 stores it in the storage unit 23 (S115).

  Subsequently, when the microcomputer 22 of the second smartphone 21 operates the touch panel 26 by the user and receives a command to set a ringtone file as a ringtone of a message (for example, an SMS message), the microcomputer 22 receives a command in S115. The ring tone file received and stored is set as a file to be played when a message is received (S120). Specifically, the setting is stored in the storage unit 23 by rewriting the file name to be played when a message arrives with the file name of the ringtone file received and stored in S115.

  Subsequently, it is assumed that a message is transmitted from the first smartphone 21 to the second smartphone 21 (S125). The microcomputer 22 of the second smartphone 21 that has received the message receives the message and stores it in the storage unit 23 (S130), and also sets the set ringtone file, that is, the ringtone file set in S120. Playback is started (S135). When the second smartphone 21 starts playing the ring tone file, the output of the audio signal (reproduced ring tone file audio signal) from the connector terminal 25 of the second smartphone 21 is started at the same time. .

  This audio signal is input to the accessory device 31 connected to the connector terminal 25 of the second smartphone 21. In the attachment device 31, the audio signal amplification amplifier 33 amplifies the audio signal, and the analysis unit 38 of the microcomputer 35 inputs the audio signal amplified by the audio signal amplification amplifier 33 and includes it in the inaudible sound portion of the audio signal.

When the detection of the ID is successful, the control unit 36 of the microcomputer 35 specifies one of the plurality of light emission patterns stored in the storage unit 37 as the light emission pattern corresponding to the ID. And the control part 36 controls the output voltage and timing to LED41, referring the value of the timer 39 so that LED41 light-emits at an appropriate timing with the specified light emission pattern.

(2) Operation example 2
Next, an operation example 2 of the content file distribution system 3 will be described using the ladder chart of FIG. In the operation example 2, after the ringtone file is received and stored by the first smartphone 21 transmitted from the server 11, the ringtone file is attached to the message and is transferred from the first smartphone 21 to the second smartphone 21. A case where a ring tone fill is transmitted and transmitted by the second smartphone 21 will be described.

  When the touch panel 26 is operated by the user and the microcomputer 22 of the first smartphone 21 receives an instruction to download the ringtone file from the server 11, the microcomputer 22 transmits the ringtone file specified by the user to the wireless communication unit 24. Through the server 11 (S205).

Upon receiving the request, the control unit 12 of the server 11 reads the requested ringing tone file from the storage unit 13 and transmits it to the first smartphone 21 via the communication unit 14 (S210).
When the microcomputer 22 of the first smartphone 21 receives the ring tone file transmitted from the server 11, the microcomputer 22 stores it in the storage unit 23 (S215).

  Subsequently, the microcomputer 22 of the first smartphone 21 attaches the ring tone file received from the server 11 to a message (for example, a message exchanged between users in a message exchange application) when the touch panel 26 is operated by the user. When the instruction to transmit to the second smartphone 21 is received, the ringtone file specified for the message input by the user is attached and transmitted to the server 11 (S220).

  The control unit 12 of the server 11 that has received the message with the ring tone file attached refers to the destination information of the message and transfers it to the destination (S225). In this example, the data is transferred to the second smartphone 21.

  The microcomputer 22 of the second smartphone 21 that has received the message to which the ring tone file is attached from the server 11 receives the message and stores it in the storage unit 23 (S230), and reproduces the attached ring tone file. Is started (S235). When the second smartphone 21 starts playing the ring tone file, the output of the audio signal (reproduced ring tone file audio signal) from the connector terminal 25 of the second smartphone 21 is started at the same time. .

  This audio signal is input to the accessory device 31 connected to the connector terminal 25 of the second smartphone 21. In the attachment device 31, the LED 41 is caused to emit light by performing the same operation as in the case of the operation example 1 described above.

(3) Configuration of Ring Tone File Next, an example of the configuration of non-audible sounds and audible sounds in the ring tone file will be described with reference to the configuration diagrams of FIGS. 5 (A) to 5 (E).

  FIG. 5A shows an example of a ringtone file in the case where a non-audible sound and an audible sound are mixed from the start to the end of the ringtone for both the left sound and the right sound. Note that even when such inaudible sounds and audible sounds are mixed, a technique such as a voice watermark is used so that the presence of the inaudible sounds does not affect the hearing state of the audible sounds.

  In FIG. 5B, in the left sound, a non-audible sound and an audible sound are mixed from the start to the end of the ringtone, while the right sound is an audible sound from the start to the end of the ringtone ( It is an example of a ringtone file in the case where it is composed of a sound of a normal music or the like and does not include an encoded ID.

  FIG. 5C shows a monaural sound, which has a non-audible sound for a certain period of time (for example, several seconds) from the start of the ringtone, and after that, an audible sound (a sound of a normal musical piece or the like encoded) This is an example of a ringtone file with a sound that does not include an ID.

  In FIG. 5D, the left voice has a non-audible sound for a certain time from the start of the ring tone, but is silent after that, and the right voice is silent for a certain time from the start of the ring tone. After that, an example of a ringtone file having an audible sound (a sound of a normal music or the like and not including an encoded ID) is shown.

  In FIG. 5E, the left voice has a non-audible sound from the start to the end of the ringtone, and the right voice is silent for a certain period from the start of the ringtone, but after that the audible sound ( It is an example of a ringtone file having a sound of a normal music or the like and not including an encoded ID.

In either example, it can be confirmed that the non-audible sound is reproduced from the start of the ring tone.
(4) Operation Timing at Incoming Call Next, the operation timing of the smartphone 21 and the attached device 31 before and after the incoming call is received by the smartphone 21 and the reproduction of the ringtone file is started will be described with reference to the timing chart of FIG. To do. 6 (A) and 6 (B) use the ring tone file having the configuration of FIG. 5 (D), and FIG. 6 (C) shows the ring tone file having the configuration of FIG. 5 (A). Is used.

(4-1) When there is an incoming call at the time of non-sleep FIG. 6A shows an operation example when there is an incoming call when the smartphone 21 is in a non-sleep state (during normal operation).

  The power pin line is 5 V when in the non-sleep state (during normal operation), and power is supplied from the smartphone 21 to the accessory device 31, and there is no change before and after the incoming call.

  In addition, the control pin line has been turned on from the beginning (a state in which an audio signal is output from the connector terminal 25). Then, when the control unit 36 of the attachment device 31 confirms that the non-audible sound part included in the left sound of the ringtone file has ended, or that the end code is included in the non-audible sound, etc. Switch the control pin line to the off state. Then, immediately after receiving it, the microcomputer 22 of the smartphone 21 switches the output destination of the audio signal from the connector terminal 25 to the speaker 28.

In addition, the control unit 36 of the attachment device 31 switches the control pin and starts the light emission of the LED 41 by the light emission pattern based on the detected ID.
As a result, the audible sound portion of the ringtone file is output from the speaker 28 of the smartphone 21 without the leading portion being lost. In addition, the start of reproduction of the audible sound part and the start of light emission of the LED 41 are synchronized.

(4-2) When there is an incoming call during sleep FIG. 6B shows an operation example when there is an incoming call when the smartphone 21 is in the sleep state (during energy saving operation). At the time of sleep, the power pin line is 0 V, and the power supply from the smartphone 21 to the accessory device 31 is cut off. As soon as an incoming call arrives, the sleep state changes to the non-sleep state, and after a slight time lag, the power pin line becomes 5V, and power supply from the smartphone 21 to the attached device 31 is started. Thereby, the attachment device 31 becomes operable.

  In addition, the control pin line is in an off state during sleep (a state in which an audio signal is output from the speaker 28 of the smartphone 21), but power supply from the smartphone 21 to the accessory device 31 is started and the accessory device 31 is turned on. When it becomes operable, the control unit 36 of the accessory device 31 switches the line of the control pin from the off state to the on state. Then, with a slight delay, the microcomputer 22 of the smartphone 21 switches the output destination of the audio signal from the speaker 28 to the connector terminal 25. As a result, the attachment device 31 can receive the input of the audio signal and detect the ID included in the non-audible sound portion. When the control unit 36 of the attached device 31 confirms that the non-audible sound part included in the left sound of the ringtone file is over or that the end code is included in the non-audible sound, the control pin 36 Return the line to off. Then, immediately after receiving it, the microcomputer 22 of the smartphone 21 switches the output destination of the audio signal from the connector terminal 25 to the speaker 28.

In addition, the control unit 36 of the attachment device 31 switches the control pin and starts the light emission of the LED 41 by the light emission pattern based on the detected ID.
As a result, the audible sound portion of the ringtone file is output from the speaker 28 of the smartphone 21 without the leading portion being lost. In addition, the start of reproduction of the audible sound part and the start of light emission of the LED 41 are synchronized.

(4-3) When an audible sound enters from the beginning of the ringtone FIG. 6C shows a case where there is an incoming call when the smartphone 21 is in a sleep state (energy saving operation) and the ringtone file It is an operation example when there is an audible sound from the head part. As described above, the operations of the smartphone 21 and the accessory device 31 when returning from the sleep state to the non-sleep state (normal operation state) are as described in (4-2) above. In the case of FIG. 6C, after the incoming call is received, the ringing tone file starts to be played before the control pin changes from the OFF state to the ON state and the output destination of the audio signal is switched from the speaker 28 to the connector terminal 25. As a result, an audible sound is output from the speaker 28. When the control pin is switched from the off state to the on state in order to detect the ID included in the audio signal of the incoming file, the output of audible sound from the speaker 28 is temporarily stopped. Thereafter, the control pin is switched from the on state to the off state, and the output of audible sound from the speaker 28 is started again.

  In other words, the user feels uncomfortable because a part of the reproduced sound is missing and heard by the user during the reproduction of the ring tone file. In particular, when returning from the sleep state to the normal operation state, since various programs operate on the microcomputer 22 of the smartphone 21, the operation load of the microcomputer 22 increases, and the output destination of the audio signal after the state of the control pin is switched. In some cases, it takes time to switch, and in this case, the beginning of the ringing tone file starts playing and there is a high possibility that a part will be lost.

Therefore, it is preferable to have a configuration as shown in FIGS. 5C to 5E, that is, a configuration in which a audible sound is not included at the head of the ringtone file.
[Effect of the embodiment]
According to the content file distribution system 3 of the above embodiment, the ringtone file that reproduces sound that is good for the user of the smartphone 21 is distributed to the accessory device 31 connected to the connector terminal 25 of the smartphone 21. Data (ID that can identify the light emission pattern) targeting the attached device 31 can be input. In addition, it is not necessary to separately provide terminals for allowing the smartphone 21 and the accessory device 31 to input data to the accessory device 31.

  Since the ring tone file is transmitted from the server 11, an administrator of the server 11 can input arbitrary data to the attachment device 31. In addition, since the accessory device 31 includes the LED 41 and the LED 41 emits light based on the light emission pattern at the time of incoming call, the smartphone 21 can also know the incoming call from the light emission. Further, the accessory device 31 can emit light by a plurality of types of light emission patterns, which are specified by the ID included in the non-audible sound portion of the incoming file. For this reason, it is possible to produce various light emission effects. Moreover, since the light emission pattern itself is specified by the ID instead of the information indicating the light emission pattern itself, it is possible to easily emit light with a complicated light emission pattern.

  In addition, the connector terminal 25 of the smartphone 21 switches whether to reproduce sound based on the audio signal from the speaker 28 provided in the smartphone 21 or to output the audio signal to the accessory device 31 connected to the connector terminal 25. There is a control pin that accepts an input for. Then, the ring tone file as shown in FIGS. 5C to 5E is used (the ring tone file having a structure in which the audible portion is not included at the head), and the attachment device 31 is permitted. The state of the control pin is switched before the reproduction of the listening part is started, and the reproduction sound based on the audio signal is output from the speaker 28. For this reason, without interrupting the beginning of the reproduced sound heard by the user of the smartphone 21, the ID can also be input to the attachment device 31 while being reproduced from the speaker 28, and the LED 41 can be caused to emit light with a light emission pattern based on the ID.
