Further, the voltage is boosted to a predetermined voltage by the booster circuit 5c. The electric power after boosting is charged into the power storage unit 3 by the charge control unit 4. Further, the DC power for supplying the microphone power supplied from the other device 500 via the conductive portion 1d is charged to the power storage unit 3 by the charge control unit 4 without performing power conversion. Note that the DC power for supplying the microphone power may be boosted by the booster circuit 5 c and then supplied to the power storage unit 3.

  Next, the configuration of the functional unit 104 will be described.

  Here, the flow of each signal when charging the power storage unit 3, when supplying power to the functional unit 104, and when transmitting data will be described.

  In FIG. 5, the power for supplying power to the functional unit 104 is indicated by a thick solid line. When the connector 101 is connected to the other device 500 via the connection unit 102, the L signal and the R signal from the other device 500 are converted into predetermined DC power by the circuit unit 5 and supplied to the function unit 104. The On the other hand, when the connector 101 is not connected to another device 500, the charge control unit 4 discharges the power charged in the power storage unit 3 and supplies it to the functional unit 104. Note that even when the connector 101 is connected to another device 500, when the charge amount of the power storage unit 3 is sufficiently large, power may be supplied from the power storage unit 3 to the functional unit 104. Further, when the connector 101 is connected to another device 500, the power of the microphone signal is supplied to the function unit 104 in addition to the L signal and the R signal or instead of the L signal and the R signal.

  In FIG. 5, data received from the other device 500 and data transmitted to the other device 500 are indicated by thin solid lines. When the function unit 104 has data in the storage unit 12, the function unit 104 transmits the data as a microphone signal via the conductive unit 1 d in the connection unit 102. In addition, the function unit 104 receives data from the other device 500 as the L signal and the R signal via the conductive units 1 a and 1 b in the connection unit 102. When data is received from another device 500, the control unit 10 controls the circuit unit 5 so as not to convert it into DC power. At this time, the data received from the other device 500 is sent to the functional unit 104 without being subjected to power conversion.

  FIG. 6A shows an external view of the electronic device 100 of the present embodiment. The holding portion 103 of the connector 101 is disposed adjacent to the root portion of the connecting portion 102 and is formed to have the shape of an animal head. The functional unit 104 provided further adjacent to the holding unit 103 is disposed so as to be folded back in the distal direction of the connection unit 102. The functional unit 104 is formed to have the shape of an animal torso. FIG. 6B shows a state where the connection unit 102 of the electronic device 100 is inserted into the earphone jack 501 of another device 500. In a state where the electronic device 100 is attached to the other device 500, the function unit 104 is arranged to be parallel to the display unit of the other device 500. Therefore, even if the electronic device 100 is connected to the other device 500, a prominent protruding portion does not occur, so that it is difficult to affect the portability of the other device 500.

  FIG. 7 is a block diagram showing a data flow when the electronic device 100 of the present embodiment is connected to another device 500. The control unit 10 of the functional unit 104 transmits the data signal output from the other device 500 in the form of the left audio signal (L signal) and the right audio signal (R signal) via the conductive units 1a and 1b of the connection unit 102. And receive. The data received by the control unit 10 is, for example, an operation start command for the sensor 11b, a data read command from the storage unit 12, and the like. When receiving an operation start command for the sensor 11b from another device 500, the control unit 10 transmits a measurement start command for the sensor 11b to the sensor microcomputer 11a included in the sensor unit 11. In addition, when data is present in the storage unit 12, the control unit 10 transmits the data via the conductive unit 1d of the connection unit 102 in the form of a microphone (MIC) signal.

  The sensor 11b included in the sensor unit 11 can be, for example, an acceleration sensor, a gyro sensor, or an atmospheric pressure sensor. By mounting these sensors, for example, functions such as walking state detection, running state detection, bicycle running state detection, vehicle state detection, sleep state detection, or atmospheric pressure state detection can be realized. Alternatively, the sensor 11b included in the sensor unit 11 may be an ultraviolet light amount sensor, an illuminance sensor, a temperature sensor, a humidity sensor, a distance measurement sensor, or a sugar content sensor. Furthermore, the sensor 11b included in the sensor unit 11 may be a vital sensor such as a pulse sensor, a blood flow sensor, or a blood pressure sensor.

  On the other hand, when the other device 500 transmits data to the electronic device 100, the transmission data generation unit 503 first modulates the data from the control unit 502 by a predetermined method, adds an error correction code, and transmits the data. Generate credit data. Next, the sound converter 504 converts the transmission data that is a digital signal into an audio signal (L signal and R signal) that is an analog signal. Finally, the sound transmission unit 505 performs amplification of the audio signal, matching of the output impedance, and the like, and outputs the result to the electronic device 100 side. The output audio signal is sent to the functional unit 104 via the conductive units 1 a and 1 b included in the connection unit 102 of the electronic device 100. Further, when the other device 500 receives data from the electronic device 100, the transmission data from the functional unit 104 of the electronic device 100 is transmitted in the form of a microphone signal that is an analog signal via the conductive unit 1d. The data is input to the recording unit 508 of the device 500. The recording unit 508 performs buffering or the like on the received signal and sends it to the sound analysis unit 507. The sound analysis unit 507 performs A / D conversion or the like of the microphone signal that is an analog signal, and transmits the converted signal to the reception data generation unit 506. The reception data generation unit 506 decodes the output from the sound analysis unit 507 by performing error correction, demodulation, and the like to generate reception data. The decrypted received data is used by the control unit 502 to operate a predetermined application.

  Next, a control example during charging and data transmission / reception of the electronic device 100 of the present embodiment is shown in a flowchart in FIG.

  The control unit 10 of the electronic device 100 determines whether or not the connector 101 is connected to another device 500 (step S101). This determination of connection can be made, for example, by notifying from the other device 500 that two members provided in the insertion port of the earphone jack 501 of the other device 500 are short-circuited by the insertion of the connector 101. If it is determined in step S <b> 101 that the connector 101 is connected to another device 500, the control unit 10 causes the charge control unit 4 to start charging control of the power storage unit 3. On the other hand, when the control unit 10 determines that the connector 101 is not connected to the other device 500, the control unit 10 cannot charge the power storage unit 3 and transmit / receive data, and thus ends the process.

  When the connection with the other device 500 is detected, the charging control unit 4 determines whether or not the power storage unit 3 is in a fully charged state (step S102). Whether or not the battery is fully charged in step S <b> 102 depends on the type of power storage unit 3. For example, in the case of a lithium ion battery, full charge can be determined by managing the charging voltage and charging current.

  If it determines with the electrical storage body 3 not being a full charge in step S102, the charge control part 4 will start charge using a microphone (MIC) signal first (step S103). When the connector 101 is inserted into a four-pole earphone jack 501 having a so-called plug-in power-compatible microphone terminal, a predetermined voltage for supplying power to the microphone is applied to the conductive portion 1d corresponding to the microphone terminal of the connection portion 102. Supplied. Charging is performed by supplying this predetermined voltage to the battery 3. Note that the charging control unit 4 monitors the voltage applied to the conductive unit 1d. The charging control unit 4 starts charging the power storage unit 3 only when a predetermined voltage is observed at the microphone terminal.

  On the other hand, if it is determined in step S102 that the power storage unit 3 is in a fully charged state, the control unit 10 executes steps relating to data transmission (after step S107) without executing steps S103 to S106 relating to charging.

  When step S103 is executed, the control unit 10 determines whether or not the conductive units 1a and 1b of the connection unit 102 are receiving audio signals (L signal and R signal) (step S104). When determining that the audio signal is not received, the control unit 10 requests the other device 500 to output the audio signal (step S105). The request for the audio signal is performed, for example, when the control unit 10 transmits a command for requesting the output of the audio signal as a microphone signal to the other device 500 via the conductive unit 1d. When charging control unit 4 is in a state of receiving an audio signal (Yes in step S104), charging control unit 4 starts charging electric storage unit 3 from the audio signal (step S106). Since the audio signal is an analog AC signal, it is possible to perform power conversion into a predetermined DC voltage suitable for charging by performing AC / DC conversion, waveform shaping, and boosting as described above. .

  Next, the control unit 10 determines whether there is untransmitted data in the storage unit 12 (step S107). In the present embodiment, the data in the storage unit 12 is, for example, a measurement result measured by the sensor 11b. When determining that data is present in the storage unit 12, the control unit 10 transmits a connection signal to the other device 500 via the conductive unit 1d (step S108). The connection signal is a signal for requesting connection to another device 500 in order to transmit data included in the electronic device 100. On the other hand, when determining that the data does not exist in the storage unit 12, the control unit 10 executes step S111 without executing steps (steps S108 to S110) related to data transmission.

  When the other device 500 is operating normally, upon receiving the connection signal transmitted by the electronic device 100 in step S108, the control unit 502 of the other device 500 sends a data request signal to the electronic device 100. Send. After executing step S108, the control unit 10 of the electronic device 100 determines whether a data request signal has been received (step S109). When determining that the data request signal has been received, the control unit 10 transmits the data in the storage unit 12 to the other device 500 (step S110). On the other hand, when determining that the data request signal has not been received, the control unit 10 transmits the connection signal again (returns to step S108) and waits until the data request signal is received.

  When the transmission of the data in the storage unit 12 is completed, the control unit 10 determines whether or not the power storage unit 3 is in a fully charged state (step S111). When controller 10 determines that power storage unit 3 is fully charged, the charging operation is terminated (step S112). Next, the control unit 10 waits until a predetermined time has elapsed from the execution of step S107 (step S113). That is, the control unit 10 determines whether or not there is data in the storage unit 12 every predetermined time, and when there is data, transmits it to the other device 500.

  If it is determined in step S113 that the predetermined time has elapsed, the control unit 10 determines whether or not the connector 101 of the electronic device 100 is connected to another device 500 (step S114). The determination in step S114 can be performed by the same method as the determination in step S101. If the control unit 10 determines that the connector 101 is still connected to the other device 500, the control unit 10 returns to step S107 and determines the presence / absence of data in the storage unit 12. On the other hand, when determining that the connector 101 and the other device 500 are not connected in step S114, the control unit 10 ends the process.

  Note that the control unit 10 continues measurement by the sensor 11b for 10 to 12 hours, for example, for 10 to 12 hours without immediately stopping the operation of the electronic device 100 even when the electronic device 100 is not connected to another device 500. The measurement result is stored in the storage unit 12. And the control part 10 monitors the charge amount of the electrical storage body 3 simultaneously via the charge control part 4, and when charge amount becomes below a predetermined value, operation | movement of the function part 104 is stopped, The electronic device 100 is shifted to the standby state. By performing such control, the electronic device 100 can operate the functional unit 104 by discharging from the internal power storage unit 3 even when power is not supplied from the other device 500. Thereby, the electronic device 100 can operate the functional unit 104 with the minimum necessary power.

  As described above, according to the present embodiment, the electronic device 100 includes the functional unit 104, the power storage unit 3, and the connector 101, and at least a part of the power storage unit 3 is arranged inside the connector 101. did. As a result, since the power storage unit 3 is disposed inside the connector 101 that has not been used as a location for the power storage unit 3 until now, an increase in the volume of the entire electronic device 100 can be reduced while the power storage unit 3 is provided.

  Further, according to the present embodiment, the power storage unit 3 is configured to be disposed particularly inside the connecting portion 102. Thereby, the increase in the volume of the electronic device 100 by providing the electrical storage body 3 can be reduced.

As a result, the power storage unit 3 can be charged simply by inserting the connection portion 102 of the electronic device 100 into the jack of another device 500.

  Further, according to the present embodiment, charging from the other device 500 to the power storage unit 3 starts charging when the electrical connection between the connector 101 and the other device 500 is detected. It was configured as follows. Thereby, charging can be started at an appropriate timing.

  Further, according to the present embodiment, when the connector 101 and the other device 500 are electrically connected, power is supplied from at least one of the other device 500 or the power storage unit 3, and the connector 101 is connected to the other device. When electrically disconnected from 500, the power storage unit 3 is configured to supply power. Accordingly, the electronic device 100 can be operated independently without depending on the other device 500, and thus the user does not need to always operate the other device 500. Therefore, power required for the operation of the functional unit 104 can be reduced.

  The connection part 202 has the electrical storage body 23 and the four conductive parts 21 inside the housing 26 made of a conductive member. The connection unit 202 can be, for example, a USB (Universal Serial Bus) Type-A Plug. FIG. 11B shows a more detailed configuration when the connecting portion 202 is viewed from the distal end side. Four conductive portions 21 are arranged at equal intervals in the longitudinal direction of the casing 26 inside the casing 26 having a rectangular opening. In FIG. 11B, a power storage unit 23 is disposed on the left side of the conductive portion 21. In the region where the power storage unit 23 is disposed, a member that insulates the casing 26 and the conductive portion 21 is disposed in a normal USB Type-A Plug. By disposing the power storage unit 23 in the region where the insulating member is disposed, an increase in the volume of the electronic device 200 can be suppressed even if the volume of the power storage unit 23 is increased. Note that, as in the first embodiment, only a part of the power storage unit 23 may be arranged inside the housing 26.

  Another device 600 to which the electronic device 200 is connected is provided with a USB receptacle 601 into which the connection unit 202 is inserted. In this embodiment as well, the specification of the connection unit 202 can be changed according to the interface of the other device 600.

  The connection unit 202 (USB Type-A Plug) according to the present embodiment includes four conductive units 21 and is assigned to + 5V, data (+), data (−), and GND, respectively. + 5V is a DC voltage, and data (+) and data (−) are AC signals having opposite polarities. Therefore, when the power storage unit 23 is charged, the data (+) and data (−) signals of the present embodiment are used instead of the L signal and the R signal in the first embodiment, and the present embodiment is used instead of the microphone signal. By using + 5V of the form, it is possible to perform charging as in the first embodiment. Note that data transmission / reception is not required via an analog signal as in the first embodiment, and digital data can be directly transmitted / received between the electronic device 200 and another device 600.

  As described above, when the conductive portion 21 is covered by the casing 26 having a relatively large volume, such as the connection section 202 (USB Type-A Plug) of the present embodiment, It is possible to accommodate the power storage unit 23 having a large volume inside. With this configuration, an increase in the volume of the electronic device 200 can be reduced while the power storage unit 23 is provided.
