The DRAM 23 is used by the main controller 20 for temporary storage of data during calculation. The USB controller 24 is connected to a USB cable. The hard disk device 25 stores a large number of music files in a predetermined format such as MP3. The wireless transmission / reception module 26 is activated when wirelessly connected to other devices directly or via a network.

  The main controller 20 reads the music data from the hard disk device 25, demodulates and decodes it, and sends the processed digital signal to the DAC 27 when reproducing the music on the hard disk device 25. The DAC 27 converts the digital signal into an analog signal and outputs the analog signal to the audio output terminal (jack) 28. The vibration sensor 29 is composed of, for example, an acceleration sensor, and detects mechanical vibration transmitted to the portable digital player 10.

  FIG. 3 shows an example of how the portable digital player 10 is used by the user 33. The user 33 puts the portable digital player 10 in the bag 34 and gets in or gets out of the car 35.

  FIG. 4 is an explanatory diagram of an in-vehicle LAN (Local Area Network) 41 constructed in the passenger compartment of the automobile 35. The head unit 39 is connected to the in-vehicle LAN 41 together with the access point 42 by wire. The speakers 40 are respectively provided on the left and right sides of the passenger compartment of the automobile 35, and are supplied with audio signals of music from the head unit 39, and output the reproduced sound of the music to the passenger compartment. After the portable digital player 10 is brought into the vehicle interior, it is wirelessly connected to the access point 42 by the operation of the wireless transmission / reception module 26. The user 33 operates the head unit 39 in the passenger compartment to output the reproduction sound of the music of the hard disk device 25 of the portable digital player 10 from the speaker 40 in the vehicle and can listen to it.

  The user 33 inserts the sound emission part of the earphone 12 into his / her ear and plays the music of the portable digital player 10 on the portable digital player 10 while getting into the automobile 35, as shown in FIG. There is a case where the player 10 is put in the car 34 and gets into the car 35 without listening to the music. In the former case, it is convenient if the playback sound output is automatically switched from the earphone 12 of the portable digital player 10 to the speaker 40 in the vehicle as soon as the user 33 enters the passenger compartment. Also in the latter case, it is convenient that the music of the portable digital player 10 can be reproduced from the speaker 40 by the user operation on the head unit 39 as soon as the user 33 enters the passenger compartment. The portable digital player 10 realizes this.

  FIG. 5 illustrates various vibrations detected by the vibration sensor 29 of the portable digital player 10 in each state of the portable digital player 10. A typical operation pattern of the user 33 when the user 33 puts the portable digital player 10 into the bag 34 and gets into the car 35 is (a) walking toward the car 35 and then ( b) Stop to open the door of the user 33, then (c) open the door and get into the car 35, then (d) lower the bag 34 to the passenger seat etc., then (E) The engine is started, and then (f) the automobile 35 is run. Therefore, by monitoring the vibration corresponding to such states (a) to (e), it is possible to grasp the movement status and current location of the user 33.

  The vibration V1 in FIG. 5 corresponds to the state of (a), that is, is a detected vibration during the walking period, and has a characteristic that both frequency and amplitude are small and continue for a predetermined time. The vibration V2 corresponds to the state of (d) and is detected when the heel 34 is lowered to a seat or the like, and has a feature that the amplitude is large and the vibration is finished in a short time. V3 corresponds to the states of (e) and (f), that is, engine vibration, and has a characteristic that the frequency is a constant value with a high amplitude, the amplitude is small, and it continues for a predetermined time.

  V1 to V3 can be clearly distinguished from each other. Thereby, for example, when detecting from the vibration detected by the vibration sensor 29 that the user 33 has entered the automobile 35 and the portable digital player 10 has entered the wireless connection area of the in-vehicle LAN 41, individual vibrations or It can be detected from a vibration pattern as a set of individual vibrations. Specifically, for example, when the vibration pattern of V2, the vibration pattern of V1 → V2, the vibration pattern of V1 → V2 → V3, or the start of V3 is detected, the portable digital player 10 is in the wireless connection area of the in-vehicle LAN 41. Judged to have entered.

  Instead of the appearance of the predetermined vibration or the predetermined vibration pattern, the disappearance of the predetermined vibration or the predetermined vibration pattern may be determined as the portable digital player 10 has entered the wireless connection area of the in-vehicle LAN 41. For example, since the user 33 stops when getting into the automobile 35, the end of V <b> 1 may be determined that the portable digital player 10 has entered the wireless connection area of the in-vehicle LAN 41. The end of V3 is presumed to be when the portable digital player 10 leaves the automobile 35. At this time, the wireless transmission / reception module 26 is stopped and the wireless connection with the head unit 39 is automatically disconnected. it can.

  FIG. 6 is a flowchart of the network search method 50 executed in the portable digital player 10. The network search method 50 automatically connects the portable digital player 10 to the head unit 39 of the automobile 35 when the user 33 gets into the automobile 35. The network search method 50 operates, for example, at regular time intervals.

  In S51, the vibration sensor 29 is turned on. Thereby, the vibration sensor 29 is switched to the operating state. In S52, it is determined whether or not the vibration detected by the vibration sensor 29 corresponds to a predetermined vibration, and the process proceeds to S53 as soon as the determination result becomes positive. The predetermined vibration is described above as the vibration when the portable digital player 10 enters the wireless connection area of the in-vehicle LAN 41, for example, the vibration of V2, the vibration pattern of V1 → V2, or V1 → V2 → V3. This is a vibration pattern.

  In S53, the wireless transceiver module 26 is turned on. In S54, connection processing to the in-vehicle LAN 41 as a wireless network is performed. In S55, it is determined whether or not the connection process to the in-vehicle LAN 41 has been completed. If the determination result is positive, the process proceeds to S56, and if not, the process proceeds to S57. If the determination result in S55 is positive, S56 may be skipped and the network search method 50 may be immediately terminated.

  In S56, the power of the vibration sensor 29 is turned off to save power. In S57, the power of the wireless transmission / reception module 26 is turned off, and the process returns to S52. If the determination in S55 is positive, the process proceeds to S56, or the network search method 50 is terminated, the power of the wireless transmission / reception module 26 is kept on, and the portable digital player 10 is wirelessly connected to the head unit 39. Keep the connection. The portable digital player 10 can transmit music data in the hard disk device 25 to the head unit 39 by holding the connection with the head unit 39, whereby the user 33 operates the head unit 39, The reproduced sound of the music can be heard from the speaker 40 in the vehicle.

  FIG. 7 is a block diagram of the portable content processing device 64. The portable content processing device 64 includes a data wireless transmission unit 65, a vibration sensor 66, a search time determination unit 67 and a search unit 68. The portable content processing device 64 can further include wireless connection control means 76, remaining power detection means 78, and notification means 79. The portable content processing device 64 is wirelessly connected to the counterpart content processing device 73 by the operation of the wireless connection module 72 and transmits or receives content data to or from the counterpart content processing device 73 via the wireless connection. Thus, the content related to the content data is made reproducible by the counterpart content processing apparatus 73 or the own device.

  Specific examples of the portable content processing device 64 and the counterpart content processing device 73 are the aforementioned portable digital player 10 (FIG. 1) and the head unit 39 (FIG. 4), respectively. Regarding the content data, the portable digital player 10 and the head unit 39 are on the transmitting side and the receiving side, respectively. And the counterpart content processing apparatus 73 may be the receiving side and the transmitting side, respectively.

  The content of the portable content processing device 64 is not limited to music but may be audio or video other than music. The counterpart content processing apparatus 73 is not limited to being mounted on a vehicle, but may be a hot spot device (eg, a personal computer and a server that distributes music for free or free of charge) that can use a wireless LAN. Good.

  Furthermore, the portable content processing device 64 may or may not be playing the content of its own device immediately before being wirelessly connected to the counterpart content processing device 73.

  The data wireless transmission means 65 wirelessly connects to the counterpart content processing device 73 by the operation of the wireless connection module 72 and performs wireless transmission of content data. The vibration sensor 66 detects vibration transmitted to the portable content processing device 64. The search time determination unit 67 determines whether or not it is a search time for searching the counterpart content processing device 73 based on the detected vibration of the portable content processing device 64. The search means 68 searches the counterpart content processing apparatus 73 by switching the wireless connection module 72 from the stopped state to the activated state at the time determined to be the search time.

  The wireless connection between the portable content processing device 64 and the counterpart content processing device 73 is not limited to the direct wireless connection between them. The counterpart content processing device 73 is connected to the network by wire, but the portable content processing device 64 may be connected to the network wirelessly. The network may be an infrastructure type network or an ad hoc type network.

  The portable content processing device 64 needs to bring the wireless connection module 72 into an operating state when searching for the counterpart content processing device 73, and frequent operation of the wireless connection module 72 is performed wirelessly with the wireless connection module 72. Although there is an advantage that the wireless connection module 72 is quickly found and enters a wireless connection state with the wireless connection module 72 when entering the connection area, the power of the battery 81 is consumed. In the portable content processing device 64, the search means 68 does not search the counterpart content processing device 73 unnecessarily, and the search timing determination means 67 is limited to the case where the vibration sensor 66 detects a predetermined vibration. Since the side content processing device 73 is to be searched, the search frequency of the wireless connection module 72 is greatly reduced, and thereby power consumption of the portable content processing device 64 can be suppressed.

  Based on the vibration detected by the vibration sensor 66, the portable content processing device 64 detects that there is a sufficient possibility that the portable content processing device 64 has entered the area of wireless connection with the counterpart content processing device 73, and the portable content processing device 64 is limited to such time. The partner content processing apparatus 73 is searched. Therefore, although the search frequency is reduced, when the search efficiency is maintained and the wireless connection with the counterpart content processing apparatus 73 is entered, the radio connection with the counterpart content processing apparatus 73 can be quickly established. it can.

  Preferably, the detected vibration includes a vibration pattern as a change in the detected vibration over a predetermined time. Specific examples of the vibration pattern include the vibration patterns of V1 → V2 and V1 → V2 → V3 described above with reference to FIG.

  For example, the predetermined vibration (for example, V2 in FIG. 4), the predetermined engine vibration (for example, V3 in FIG. 4), and / or the mobile vibration detected by the search time determination unit 67 based on the determination of the search time. There is a predetermined vibration (for example, V1 in FIG. 4) during walking of the user who carries the type content processing apparatus.

  Preferably, the search means 68 determines the ID of the network connected for the search of the counterpart content processing apparatus 73, and if the calculated network ID is not a predetermined one, there is no counterpart content processing apparatus for the ID. Judge. For example, there is a case where another person's automobile is parked next to the own vehicle, and the other person's automobile is also equipped with a wireless network. In such a case, the searching means 68 may connect to the other person's automobile network in response to the radio wave leaking from the other person's automobile network. The search for the counterpart content processing apparatus 73 by identifying the network ID can prevent such an adverse effect.

  Preferably, the search time determination unit 67 learns the detected vibration when the counterpart content processing device 73 is found, and the counterpart content based on the comparison between the detected vibration of the learning result and the vibration sensor 66 detected this time. It is determined whether it is time to search for the processing device 73. In order to avoid missing the portable content processing device 64 in the wireless connection range with the counterpart content processing device 73, the width of coincidence with the reference vibration to be compared with the detected vibration is first Is set relatively large. As a result, the search frequency of the partner content processing apparatus 73 by the search means 68 increases, and the power consumption of the battery 81 is correspondingly large. As learning progresses, the width of the match between the detected vibration and the reference vibration decreases, and the search frequency can be reduced while the search success rate is kept high, thereby suppressing the power consumption of the battery 81. .

  Typically, the counterpart content processing apparatus 73 is an in-vehicle device. The search time determination means 67 determines whether or not the portable content processing device 64 has been brought into the vehicle from outside the vehicle based on the vibration detected by the vibration sensor 66. The search time for the processing device 73 is set. The search for the head unit 39 in the automobile 35 by the portable digital player 10 is an example of this.

  The portable content processing device 64 preferably includes wireless connection control means 76. If the counterpart content processing apparatus 73 is found as a result of the search by the search means 68, the wireless connection control means 76 maintains the wireless connection module 72 and maintains the wireless connection with the counterpart content processing apparatus 73. .

  When the wireless connection control unit 76 maintains the wireless connection with the counterpart content processing device 73 and the state of no access to the portable content processing device 64 from the counterpart content processing device 73 reaches a predetermined time value or more, The operation of the connection module 72 is stopped and the wireless connection with the counterpart content processing apparatus 73 is disconnected. Thus, even after the wireless connection is established with the counterpart content processing device 73, if it is determined that the wireless connection is useless, the operation of the wireless connection module 72 can be stopped to save power.

  In disconnection of a wireless connection accompanying the passage of a no-access state greater than or equal to a predetermined time value, the searching means 68 is connected to the counterpart content processing apparatus 73 after disconnecting another predetermined time from the counterpart content processing apparatus 73. May be reconnected. As a result, it is possible to avoid as much as possible the disconnection of the wireless connection when the transmission / reception of the content data is started again with the counterpart content processing apparatus 73.

  The portable content processing device 64 can include a remaining power detection unit 78 and a notification unit 79. The remaining power detection means 78 detects the remaining power of the battery 81 as a power source for the portable content processing device 64. The notification unit 79 notifies the counterpart content processing device 73 of information related to the remaining power level when the remaining power level is less than or equal to the predetermined value. The battery 81 is, for example, a rechargeable type or a dry cell type. The wireless connection control means 76 stops the operation of the wireless connection module 72 and disconnects the wireless connection with the counterpart content processing apparatus 73 after the notification means 79 notifies the counterpart content processing apparatus 73. If the wireless connection between the portable content processing device 64 and the counterpart content processing device 73 is disconnected without such notification, the user misunderstands that the portable content processing device 64 is out of order, and the vibration sensor 66. In some cases, the portable content processing device 64 may be intentionally hit so as to be detected by vibration. This notification can suppress such a useless action and prevent a user from being suspicious.

  Preferably, the search means 68 detects whether or not the portable content processing device 64 stays in the automobile based on whether or not the vibration detected by the vibration sensor 66 corresponds to a predetermined engine vibration. In a period in which the processing device 64 remains in the vehicle, the re-search for the in-vehicle device is repeated until the in-vehicle device is found. Since engine vibrations are vibrations specific to the vehicle interior, it is possible to accurately grasp that the portable content processing device 64 is in the vehicle by detecting engine vibrations. The portable content processing device 64 may temporarily be unable to wirelessly connect to the counterpart content processing device 73 due to a temporary cause such as the counterpart content processing device 73 being turned off. Thus, when the counterpart content processing apparatus 73 is restored, the portable content processing apparatus 64 can be quickly connected to the counterpart content processing apparatus 73.

  Further, preferably, the search unit 68 limits the repetition of the re-search for the in-vehicle device within a predetermined time or a predetermined number of times. The search means 68 may extend the time interval for repeating the re-search of the counterpart content processing apparatus 73 as time passes.

  Preferably, the wireless connection control unit 76 maintains the connection with the in-vehicle device regardless of the remaining power of the battery 81 during the period when the portable content processing device 64 is supplied with power from the external power source. As a result, when there is no concern about the power failure of the portable content processing device 64, the portable content processing device 64 is continuously wirelessly connected to the counterpart content processing device 73, and the content data is transferred to the portable content processing device. 64-transmission / reception between the content processing apparatuses 73 on the other side can ensure reproduction without trouble.

  FIG. 8 is a flowchart of the control method 90 for the portable content processing apparatus. The portable content processing device control method 90 wirelessly connects to the counterpart content processing device 73 by the operation of the wireless connection module 72 to perform wireless transmission of content data. The portable content processing device control method 90 is activated at regular time intervals, for example, during a stop state period (= non-power supply period) of the wireless connection module 72.

  In S91, based on the vibration detected by the vibration sensor 66, it is determined whether or not it is a search time for searching the counterpart content processing apparatus 73. In S92, based on the determination result of S91, if the determination result is positive, the process proceeds to S93, and if not, the portable content processing apparatus control method 90 is terminated. In S93, the wireless connection module 72 is switched from the stopped state to the activated state, and the counterpart content processing device 73 is searched. If the portable content processing device control method 90 is terminated in S92, the wireless connection module 72 is continuously maintained in the non-powered state and maintained in the stopped state.

  The processes of S91 and S93 correspond to the functions of the search time determination unit 67 and the search unit 68 of the portable content processing device 64, respectively. Therefore, the specific modes described for the functions of the search time determination unit 67 and the search unit 68 can also be applied as specific modes for the processing of S91 and S93.

  The functions of the remaining power detection means 78 and the notification means 79 of the portable content processing apparatus 64 described with reference to FIG. 7, and the search time determination means that cooperates with the remaining power detection means 78 and the notification means 79. 67, it is possible to construct a method comprising steps for executing processing corresponding to the functions of the search means 68 and the wireless connection control means 76, respectively. Specific modes of the functions of the search time determination unit 67, the search unit 68, the wireless connection control unit 76, the remaining power detection unit 78, and the notification unit 79 in such a cooperative function are as follows. It is applicable also as a concrete aspect about.
