And Dohon connection determination unit 18, is configured to include a.

  The main control means 11 includes a ROM for storing a control program corresponding to various functions, a RAM as an execution area of the program, and a CPU for executing the program, and a program corresponding to a user operation input from the user interface means 12 Is executed to control operation processing of various functions such as a voice call function, a music playback function, and a personal information management function. For example, when an instruction to reproduce music data is given from the user interface means 12, the main control means 11 instructs the reproducing means 16 to read out and reproduce the music data stored in the storage means 15. .

  The user interface unit 12 is an input / output unit configured to include a key input unit such as a numeric keypad, a voice input / output unit such as a microphone and a speaker, and a display unit such as an LCD (Liquid Crystal Display).

  The call control means 13 is a circuit for controlling the operation of the wireless means 14 based on an instruction given from the main control means 11, and is a circuit that implements hardware processing for transmission / reception signals or a voice call (telephone function). The peripheral circuit necessary for the is included.

  The wireless unit 14 is a circuit for performing frequency setting, modulation / demodulation, and the like of a transmission / reception signal based on an instruction given from the call control unit 13. For example, a rod antenna excellent in portability and storage property is preferably used as the antenna connected to the wireless unit 14.

  The storage means 15 is a means for storing music data obtained by downloading from a server connected to a network, for example, a non-volatile semiconductor memory such as a flash memory or a magnetic storage medium such as a hard disk. It is configured. In addition, the storage unit 15 may be an external recording medium such as a memory card. In this case, the mobile terminal device 10 allows the storage unit 15 to be detachably mounted.

  Based on the instruction given from the main control means 11, the reproduction means 16 reads the music data stored in the storage means 15, and decodes the music data by a predetermined algorithm to generate an analog electric signal. The generated analog electrical signal is sent to the headphone 30 via the headphone connection means 17.

  The headphone connecting means 17 is a connector for attaching / detaching the headphones 30 to / from the output terminal of the reproducing means 16, and the terminal shape is arbitrary.

  The headphone connection determination means 18 constantly monitors the connection state of the headphones 30 in the headphone connection means 17, and if it is determined that the headphones 30 have been removed from the headphone connection means 17, notifies the main control means 11 to that effect.

  The headphone 30 is an earpiece worn on the user's ear, and is detachably connected to the mobile terminal device 10 via the headphone connection means 17. When the music data is played back by the mobile terminal device 10, the headphones 30 are connected to the headphone connection means 17. As a result, the user can listen to desired music via the headphones 30.

  In FIG. 1, when the main control means 11 determines that the headphones 30 have been removed from the headphone connection means 17 during the reproduction of the music data, the main control means 11 pauses the reproduction of the music data, and the headphones 30 reconnects to the headphone connection means 17. When it is determined that the connection has been established, the reproduction is resumed from a predetermined reproduction start position. The reproduction start position may be simply resumed from the position where the reproduction was paused, but the reproduction start position may be set by the user in advance. This will be described with reference to FIGS.

  FIG. 2 is a flowchart for explaining an example of music data reproduction pause processing and reproduction resume processing by the mobile terminal device 10 shown in FIG. Note that the flow shown in this example starts from a state in which the headphones 30 are connected to the headphone connection means 17.

  First, the mobile terminal device 10 determines whether or not the headphones 30 have been removed from the mobile terminal device 10 (headphone connection means 17) by the headphone connection determination means 18 (step S1), and determines that the headphones 30 have not been removed. If it is determined (in the case of NO), the determination process is continued in step S1. On the other hand, when it is determined in step S1 that the headphones 30 have been removed (in the case of YES), this is notified to the main control means 11.

  Next, the main control means 11 determines whether or not the music data is currently being reproduced by the notification from the headphone connection determination means 18 (step S2), and if it is determined that the music data is not currently being reproduced (NO) ), Even if the headphones 30 are removed, there is no need to automatically stop the reproduction of the music data, so the subsequent steps S3 to S6 are skipped, and the series of processes is terminated. If it is determined in step S2 that the music data is currently being played back (in the case of YES), the main control means 11 instructs the playback means 16 to pause the playback of the music data ( Step S3). The reproduction means 16 temporarily stops the music data according to the instruction from the main control means 11.

  Next, the main control means 11 performs a process of determining a position at which the reproduction of the music data is resumed (step S4). Here, for example, a position at which music data is paused is set as a reproduction restart position.

  Next, the mobile terminal device 10 determines whether or not the headphones 30 are connected to the mobile terminal device 10 (headphone connection means 17) again by the headphone connection determination means 18 (step S5), and the headphones 30 are not connected. Is determined (in the case of NO), determination processing is continued in step S5. On the other hand, when it is determined in step S5 that the headphones 30 are connected (in the case of YES), the main control means 11 is notified of this.

  Next, the main control means 11 resumes the reproduction of the music data from the reproduction resume position (here, the paused position) determined in step S4 by the notification from the headphone connection determination means 18 (step S6). In this example, the post-processing of step S6 is finished. However, after the reproduction is resumed in step S6, the process may return to step S1 and the following steps may be repeated.

  Here, the process for determining the reproduction restart position in step S4 may be executed after step S5. Further, the process for determining the playback restart position in step S4 and the playback pause process in step S3 may be reversed. In this case, the reproduction of the music data is paused after the reproduction restart position is determined.

  As described above, during playback of music data, when the headphones 30 are removed from the headphone connection means 17, the music data is temporarily stopped, and when the headphones 30 are connected again to the headphone connection means 17, Playback resumes from the playback resume position. For this reason, the user can suspend the music simply by removing the headphones 30 and can resume the reproduction just by connecting the headphones 30. Thus, the user performs the reproduction start operation after connecting the headphones 30 as in the prior art. There is no need, and the operation can be simplified. It is also possible to prevent unnecessary battery consumption due to forgetting to stop music playback.

(Second Embodiment)
FIG. 3 is a block diagram illustrating a configuration example of the mobile terminal device according to the second embodiment of the present invention. The mobile terminal device 10 of this embodiment includes a main control unit 11, a user interface unit 12, a call control unit 13, a wireless unit 14, a storage unit 15, a playback unit 16, a headphone connection unit 17, and an ear wearing determination unit 19. Configured. The ear wearing determination means 19 is provided instead of the headphone connection determination means 18 in the first embodiment. Here, the same parts as the portable terminal device 10 of the first embodiment (main control means 11, user interface means 12, call control means 13, wireless means 14, storage means 15, reproduction means 16, headphone connection means 17) Are denoted by the same reference numerals as those in FIG. 1, and the description thereof is saved.

  The ear wearing determination means 19 constantly monitors whether or not the headphones 30 are attached to the user's ears, and if it is determined that the headphones 30 have been removed from the user's ears, it notifies the main control means 11 accordingly. . The headphone 30 also includes ear mounting detection means 31 that is a sensor for detecting whether the headphone 30 is mounted on the user's ear. When detecting that the headphones 30 have been removed from the user's ear, the ear wearing detection means 31 sends an output signal for notifying the fact to the ear wearing determination means 19.

  The ear wearing determination unit 19 determines whether the headphones 30 are worn on the user's ear based on the output signal from the ear wearing detection unit 31. The ear wearing detection means 31 may be a mechanical sensor or an optical sensor, but the detection method is not particularly limited.

  In FIG. 2, when the main control means 11 determines that the headphones 30 have been removed from the user's ears based on the output signal from the ear wearing detection means 31 during the reproduction of the music data, the main control means 11 temporarily reproduces the music data. When it is determined that the headphones 30 have been put on the user's ear again, the reproduction is resumed from a predetermined reproduction start position. As in the first embodiment, the playback start position may be restarted from the position where the playback has been temporarily stopped, but the playback start position may be set in advance by the user.

  FIG. 4 is a flowchart for explaining an example of music data reproduction pause processing and reproduction resume processing by the mobile terminal device 10 shown in FIG. Note that the flow shown in this example starts from a state in which the headphones 30 are attached to the user's ears.

  First, the mobile terminal device 10 determines whether or not the headphone 30 has been removed from the user's ear by the ear wearing determination unit 19 (step S11), and when the headphone 30 has not been removed from the user's ear. (In the case of NO), the determination process is continued in step S11. On the other hand, if it is determined in step S11 that the headphones 30 have been removed from the user's ear (in the case of YES), this is notified to the main control means 11.

  Next, the main control means 11 determines whether or not the music data is currently being reproduced by the notification from the ear wearing determination means 19 (step S12), and if it is determined that the music data is not currently being reproduced (NO) ), Even if the headphones 30 are removed from the user's ears, it is not necessary to automatically stop the reproduction of the music data, so the subsequent steps S13 to S16 are skipped, and the series of processing ends. If it is determined in step S12 that the music data is currently being played back (in the case of YES), the main control means 11 instructs the playback means 16 to pause the playback of the music data ( Step S13). The reproduction means 16 temporarily stops the music data according to the instruction from the main control means 11.

  Next, the main control means 11 performs a process of determining a position at which the reproduction of the music data is resumed (step S14). Here, for example, a position at which music data is paused is set as a reproduction restart position.

  Next, the mobile terminal device 10 determines whether or not the headphone 30 is mounted on the user's ear again by the ear mounting determination unit 19 (step S15), and determines that the headphone 30 is not mounted on the user's ear. If (NO), the determination process is continued in step S15. On the other hand, if it is determined in step S15 that the headphones 30 are attached to the user's ear (in the case of YES), this is notified to the main control means 11.

  Next, the main control means 11 resumes the reproduction of the music data from the reproduction resuming position (here, the paused position) determined in step S14 by the notification from the ear wearing determination means 19 (step S16). In this example, the processing after step S16 is ended. However, after the reproduction is resumed in step S16, the processing may return to step S11 and the following steps may be repeated.

  Here, the process for determining the reproduction restart position in step S14 may be executed after step S15. Further, the process for determining the playback restart position in step S14 and the playback pause process in step S13 may be reversed. In this case, the reproduction of the music data is paused after the reproduction restart position is determined.

  In this way, during playback of music data, when the headphones 30 are removed from the user's ears, the music data is paused, and when the headphones 30 are connected again to the user's ears, predetermined playback resumes. Playback resumes from the position. For this reason, the user can pause the music simply by removing the headphones 30 from the ear, and can resume the playback just by attaching the headphones 30 to the ear. There is no need to perform a start operation, and the operation can be simplified. It is also possible to prevent unnecessary battery consumption due to forgetting to stop music playback.

  FIG. 5 is a diagram illustrating an example of a position where reproduction is resumed after music data is temporarily stopped. In the figure, m1 is the current (pause) music data, m2 is the previous music data, S is the pause position, and R is the playback resume position. Hereinafter, description will be made based on FIG. 3 described above.

  5A, when the music data m1 is being reproduced, when the headphones 30 are removed from the user's ear, the reproduction of the music data m1 is stopped. The position at this time is set as a reproduction stop position S. In this example, the playback stop position S is set as the playback restart position R. Then, when the headphones 30 are put on the user's ear again, the music data m1 is reproduced from the reproduction restart position R.

  In FIG. 5B, when the headphone 30 is removed from the user's ear during the reproduction of the music data m1, the reproduction of the music data m1 is stopped at the reproduction stop position S. In this example, a position before a certain time (can be set by the user) from the reproduction stop position S is set as a reproduction restart position R. Then, when the headphones 30 are put on the user's ear again, the music data m1 is reproduced from the reproduction restart position R.

  In FIG. 5C, when the headphone 30 is removed from the user's ear during the reproduction of the music data m1, the reproduction of the music data m1 is stopped at the reproduction stop position S. In this example, when the previous music data m2 includes a position before the reproduction stop position S for a certain time (which can be set by the user), the start position of the music data m1 is set as the reproduction resume position R. Then, when the headphones 30 are put on the user's ear again, the music data m1 is reproduced from the reproduction restart position R.

  In FIG. 5D, when the headphone 30 is removed from the user's ear during the reproduction of the music data m1, the reproduction of the music data m1 is stopped at the reproduction stop position S. In this example, when the reproduction stop position S is included in the music data m1, the head position of the music data m1 is set as the reproduction resume position R. Then, when the headphones 30 are put on the user's ear again, the music data m1 is reproduced from the reproduction restart position R.

  FIG. 6 is a diagram illustrating another example of a position where reproduction is resumed after music data is paused. In the figure, m1 represents current (paused) music data, m3 represents the next music data, S represents a pause position, and R represents a playback resume position.

  In FIG. 6A, when the headphone 30 is removed from the user's ear during the reproduction of the music data m1, the reproduction of the music data m1 is stopped at the reproduction stop position S. In this example, when the reproduction stop position S is included in the music data m1, the start position of the next music data m3 is set as the reproduction resume position R. Then, when the headphones 30 are put on the user's ear again, the next music data m3 is reproduced from the reproduction restart position R.

  In FIG. 6B, when the headphone 30 is removed from the user's ear during the reproduction of the music data m1, the reproduction of the music data m1 is stopped at the reproduction stop position S. In this example, when the reproduction stop position S is included within a certain time (can be set by the user) from the end position of the music data m1, the start position of the next music data m3 is set as the reproduction resuming position R. Then, when the headphones 30 are put on the user's ear again, the next music data m3 is reproduced from the reproduction restart position R.

  In FIG. 6C, when the headphone 30 is removed from the user's ear during the reproduction of the music data m1, the reproduction of the music data m1 is stopped at the reproduction stop position S. In this example, when the reproduction stop position S is included in the fade-out section of the music data m1 (that is, the volume level gradually decreases), the start position of the next music data m3 is set as the reproduction resume position R. Then, when the headphones 30 are put on the user's ear again, the next music data m3 is reproduced from the reproduction restart position R.

  As described with reference to FIGS. 5 and 6, in step S <b> 4 in FIG. 2 or step S <b> 14 in FIG. 4, the main control unit 11 performs processing for determining a position at which reproduction of music data is resumed. It should be noted that it is possible to arbitrarily set the position at which reproduction is resumed by user setting. As described above, since the music reproduction restart position can be set in advance, the user can resume music reproduction from a desired position when the headphones are worn.

  Here, for example, when the music that was being listened to at a high volume is paused, if the volume level is maintained as it is, the playback of the music will start at a high volume when playback is resumed, which will surprise the user. It can happen. In order to deal with such a case, a method as shown in FIG. 7 below may be used.

  FIG. 7 is a diagram illustrating an example of music data reproduction restart processing. When the reproduction of the music data m1 and m3 shown in FIG. 5 and FIG. 6 is resumed, the volume level is gradually increased (fade in) and controlled to reach a predetermined volume level. The volume level can be set by the user, but may be returned to the volume level at the time of pause, for example. The control of the volume level when resuming playback is executed by the main control means 11. Thereby, when the reproduction of the music is resumed, it does not start suddenly at a loud volume, and the user is not surprised.

As described above, according to the present invention, when headphones are removed from a user's ear or the like while listening to music with a mobile terminal device having a music playback function, the music being played back at that time is displayed. When stopped, and when headphones are attached again, playback of music that has been stopped can be resumed, eliminating the need for the user to operate the pause button / pause release (play) button each time the headphones are removed. The operation can be simplified.
In addition, since the music playback resume position can be set in advance, the user can resume music playback from a desired position when the headphones are worn.
