  Hereinafter, an embodiment of the present invention will be described.

<First embodiment>
FIG. 1 is a diagram showing a portable media player 10 according to the present embodiment. The portable media player 10 includes a main body 11 and an earphone 21.

  The main body 11 includes an arithmetic processing device 12, a storage device 13, a display 14, and operation buttons 15. The earphone 21 includes a speaker 22 and a motion sensor 23, and is connected to a connection terminal of the main body 11 via a cord 30.

  The arithmetic processing unit 12 is a central unit that performs various processes of the portable media player 10. Specifically, the arithmetic processing unit 12 receives an instruction from the user via the operation button 15 or the motion sensor 23, and turns on the power from the sleep state (the display 14 is stopped). Note that the arithmetic processing unit 12 shifts to a sleep state, for example, stops display on the display 14 when a predetermined time elapses without receiving a predetermined operation from the user.

  The arithmetic processing unit 12 receives an instruction from the user via the operation button 15 or the motion sensor 23, and executes predetermined processing such as playback or stop of the digital music file. The predetermined processing executed by the arithmetic processing unit 12 is defined by processing data 40 stored in a ROM described later. Details of such processing will be described later. The display 14 may have a touch panel, and in this case, the arithmetic processing device 12 may receive an instruction from the user via a touch operation on the touch panel.

  Further, the arithmetic processing unit 12 displays predetermined image information indicating the processing content on the display 14.

  Such an arithmetic processing unit 12 includes a CPU (Central Processing Unit) that executes various processes such as numerical operations, a RAM (Random Access Memory) that temporarily stores programs, data, and calculation results, programs, A ROM (Read Only Memory) for storing data and the like, and an I / F (interface) for connecting each piece of hardware such as the storage device 13 and the motion sensor 23 to the arithmetic processing unit 12 are provided. The CPU, RAM, and ROM are connected to each other by a bus. Moreover, these may be integrated into one IC (Integrated Circuit) chip.

  FIG. 2 is a diagram showing an example of the processing data 40 stored in the ROM. In the processing data 40, the movement (for example, the tilt direction and the number of signal acquisition) 41 of the earphone 21 detected by the motion sensor 23 and the processing content 42 by the arithmetic processing device 12 are recorded in association with each other.

  For example, as shown in the figure, the process of turning on the power is associated with “acquiring the signal indicating the rightward inclination twice in the sleep state”. Further, “a signal indicating a rightward inclination in a state where the power is on is acquired twice” is associated with a process of a sleep state. Further, “acquisition of a signal indicating a leftward inclination” is associated with a process called item selection. Further, “acquisition of a signal indicating a rightward inclination” is associated with a process of reproducing digital data (for example, music file, moving image data, etc.). In addition, “acquire a signal indicating a forward tilt” is associated with a process of determining a selection item. Further, “acquiring a signal indicating a rightward inclination during reproduction” is associated with a process of stopping reproduction. In addition, “acquiring a signal indicating a leftward tilt during reproduction” is associated with a process of skipping the next song. Further, a process of “acquiring a signal indicating a forward tilt during reproduction” is associated with a process of volume (volume) Up. The arithmetic processing unit 12 executes a predetermined process according to the movement (tilt direction or vibration) of the earphone 21 based on such a definition of the processing data 40.

  The ROM stores image information indicating a predetermined process defined by the process data 40. FIG. 3 is a diagram illustrating a processing mark that is image information. As shown in the figure, the processing mark stores a playing mark 51 indicating that playback is in progress, a stop mark 52 indicating that playback is stopped, and a skip mark 53 indicating skipping to the next song. Has been. The arithmetic processing unit 12 displays a processing mark on the display 14 when executing the processing defined by the processing data 40. As shown in FIGS. 1 and 5, the display 14 may display image information indicating a tilt state in a predetermined direction detected by the motion sensor 23 during music reproduction or the like.

  In addition, a decoder is stored in the ROM. The decoder is software for playing back a digital music file compressed in a predetermined format. The decoder decompresses and decrypts the encrypted and encoded digital data. The decoder plays back the decrypted digital music file. Note that the decoder is not necessarily software, and may be configured by hardware mounted on a microchip, for example.

  The storage device 13 is composed of at least a readable / writable recording medium such as a nonvolatile memory card. The storage device 13 stores music files, moving image data, still image data, and the like.

  The display 14 is composed of a small monitor capable of displaying at least character information. The type of monitor is not limited. The display 14 displays the processing mark, predetermined character information, date / time information (clock display) indicating the date and time, and the like.

  The operation button 15 is hardware for transmitting an instruction from the user to the arithmetic processing device 12. Specifically, the operation button 15 receives an instruction from the user to execute a function provided in the portable media player 10 such as playing or stopping a music file, displaying a moving image or a still image.

  The speaker 22 incorporated in the earphone 21 outputs music or melody that can be recognized by hearing by converting music such as a music file stored as digital data into physical vibration.

  The motion sensor 23 is a sensor that can detect an operation, a direction of inclination, a size thereof, and the like by measuring a displacement (movement) of an object. FIG. 4 is a wearing image diagram of the headphones 60 in which the motion sensor 23 is built. FIG. 5 is a diagram in which the image diagram of FIG. 4 is drawn three-dimensionally. The motion sensor 23 is configured by, for example, a three-dimensional acceleration sensor that can measure acceleration in each of three axes (X axis, Y axis, and Z axis). The detection method of the three-dimensional acceleration sensor may be any method such as a capacitance type or a piezoresistive type.

  The motion sensor 23 does not necessarily need to be configured by a three-dimensional acceleration sensor, and may be configured by a gyro sensor as long as it can detect the movement of an object, and is a six-axis sensor that combines the three-dimensional acceleration sensor and the gyro sensor. There may be.

  Further, the motion sensor 23 may be constituted by a vibration sensor. The vibration sensor is a sensor that outputs a predetermined signal when detecting vibration of the mounted object. As the vibration sensor, an appropriate sensor may be mounted according to the characteristics of the vibration to be detected (the magnitude of vibration, the frequency band, etc.). The vibration sensor is not limited to a detection method such as a capacitance type or an eddy current type.

  Such a motion sensor 23 generates a signal indicating the direction in which the object has moved and an output value proportional to the magnitude and acceleration of the movement.

  The motion sensor 23 includes a mechanical mechanism and an electronic circuit integrated on a single silicon wafer using a MEMS (micro electro mechanical systems) technology developed in recent years, that is, a semiconductor manufacturing technology. By being composed of integrated functional devices (acceleration sensor, gyro sensor, etc.), it is effective for miniaturization of the portable media player 10.

  In the present embodiment, since the motion sensor 23 is built in the earphone 21, when the user of the portable media player 10 tilts his / her neck, the output is proportional to the direction of tilt and the speed and magnitude of the motion. A signal indicating the value is output to the arithmetic processing unit 12. Therefore, the arithmetic processing device 12 can receive a user instruction by a signal output from the motion sensor 23. Note that the motion sensor 23 may be mounted only on one earphone 21 or may be mounted on both earphones 21. Further, the portable media player 10 may perform information transmission with the headphones 60 by wireless communication. Furthermore, the function of the portable media player 10 may be built in the headphones 60.

  Next, functional blocks of the portable media player 10 will be described. The functional block of the portable media player 10 is constructed by executing a predetermined program read by a CPU mounted on the arithmetic processing unit 12. Therefore, the ROM stores a program for executing processing of each functional unit.

  The functional blocks of the portable media player 10 are classified according to main processing contents in order to facilitate understanding of the functions of the portable media player 10 realized in the present embodiment. Further, the present invention is not limited by the classification method of each function or its name. Note that each configuration of the portable media player 10 can be classified into more components according to the processing content. Moreover, it can also classify | categorize so that one component may perform more processes.

  The functional unit of the portable media player 10 may be constructed by hardware. Further, the processing of each functional unit may be executed by one hardware or may be executed by a plurality of hardware.

  FIG. 6 is a functional block diagram of the portable media player 10. The portable media player 10 includes a control unit 71, a playback unit 72, and an item selection unit 73.

  The control unit 71 is a central functional unit that performs various processes of the portable media player 10. Specifically, the control unit 71 receives a user instruction via the operation button 15 and the motion sensor 23, and outputs a signal instructing a predetermined process to another functional unit or device.

  Further, the control unit 71 turns on the portable media player 10 according to the acquired signal. In addition, the control unit 71 increases or decreases the volume (volume) according to the acquired signal.

  Further, the control unit 71 determines the selection of the menu item according to the acquired signal.

  The playback unit 72 is a functional unit that plays back music files, moving image data, and the like. Specifically, the playback unit 72 decompresses and decrypts a target music file and reproduces these digital data. Further, the playback unit 72 stops playback of a music file or the like in accordance with a user instruction.

  The item selection unit 73 is a functional unit that selects a menu item in accordance with a user instruction. The menu items are divided into a plurality of hierarchies. For example, in the uppermost first hierarchy, large-scale menu items such as “music”, “moving image”, and “still image” are stored. Further, the second hierarchy stores middle category menu items associated with the items of the first hierarchy. For example, menu items such as “album”, “artist”, “genre (for example, jazz, classic)”, and “age” are stored in the second hierarchy associated with “music”. The “moving image” item and the “still image” item are also stored in association with the middle class items. The item selection unit 73 selects any one of these menu items according to an instruction from the user. Note that such menu items for each hierarchy are stored in the ROM in advance.

  The music file includes predetermined information such as an album name, artist name, genre, and age, and the control unit 71 identifies a specific music file by creating a reference list storing these information. be able to. That is, when “album” is selected by the item selection unit 73, the control unit 71 can identify an album stored in the storage device 13 and specify a recorded music file. When “artist” is selected by the item selection unit 73, the control unit 71 can specify the music file stored in the storage device 13 for each artist. Similarly, when “genre” or “age” is selected, a specific music file is specified based on these pieces of information. Therefore, when the user selects these menu items, the control unit 71 can specify a music file to be reproduced.

  The functional blocks of the portable media player 10 according to this embodiment have been described above.

  Next, processing executed by the portable media player 10 will be described. FIG. 7 is a flowchart showing the power-on process. Such processing is started when the portable media player 10 enters a sleep state.

  The control unit 71 monitors whether or not a signal for instructing power ON is acquired from the user via the motion sensor 23 (step S001). Specifically, the control unit 71 determines whether or not a signal indicating a rightward inclination has been acquired twice. Whether or not the signal is acquired twice is determined by whether or not the second signal is acquired within a predetermined time (for example, within 3 seconds) after the first signal acquisition.

  When the signal indicating the rightward tilt is acquired twice (Yes in step S001), the control unit 71 turns on the power of the portable media player 10 (step S002) and ends the power-on process. On the other hand, when such a signal is not acquired (No in step S001), the control unit 71 continues to monitor acquisition of a signal for instructing power ON.

  Next, playback processing of the portable media player 10 will be described. FIG. 8 is an example of a flowchart showing such processing. The reproduction process is started when the portable media player 10 is turned on.

  The controller 71 monitors whether or not a signal has been acquired from the motion sensor 23 (step S011). When the signal is acquired (Yes in step S011), the control unit 71 determines whether or not the output value of the signal is greater than a predetermined threshold (step S012). The process proceeds to step S013. On the other hand, when the signal is not acquired from the motion sensor 23 (No in step S011) or when the output value of the acquired signal is smaller than the threshold value (No in step S012), the control unit 71 moves the process to step S011. Return and monitor for signal acquisition again.

  Note that the control unit 71 acquires an interrupt request signal output when the motion sensor 23 detects a tilt in a predetermined direction, or performs an interval timer every predetermined time (for example, 0.3 seconds to 0.5 seconds). The presence or absence of signal acquisition is monitored by determining the presence or absence of signal acquisition.

  In step S013, the control unit 71 executes a reproduction process according to the inclination direction of the earphone 21 indicated by the signal. Hereinafter, each case of such processing will be described.

  (1) When the signal acquired from the motion sensor 23 indicates a leftward tilt, the item selection unit 73 selects a menu item. Specifically, the item selection unit 73 selects menu items in the first layer such as “music”, “moving image”, and “still image” by sequentially sliding each time such a signal is acquired. For example, when the selection of “music” is confirmed, the item selection unit 73 selects a lower-level second-level menu item associated with “music”. In this case, each time such a signal is acquired, the item selection unit 73 selects menu items in the second hierarchy such as “album”, “artist”, “genre”, and “age” by sequentially sliding them.

  (2) When the signal acquired from the motion sensor 23 indicates a forward tilt, the control unit 71 determines the menu item selected by the item selection unit 73. For example, when “music” in the first hierarchy is selected, when such a signal is acquired, the control unit 71 determines “music” as the selected menu item. When the selected menu item is confirmed, the control unit 71 notifies the item selection unit 73 that the menu item to be selected has been moved to a lower hierarchy.

  (3) When the signal acquired from the motion sensor 23 indicates a rightward tilt, the playback unit 72 uses predetermined digital data (music file, moving image file, still image file, etc.) selected by the item selection unit 73. ). Specifically, the playback unit 72 extracts the selected music file or the like from the storage device 13 and plays it.

  (4) If the signal acquired from the motion sensor 23 indicates a rightward tilt during playback of digital data (music file, video data, etc.), the playback unit 72 stops playback of the music file or the like. .

  (5) If the signal acquired from the motion sensor 23 indicates a leftward tilt during playback of digital data (music file or video data), the playback unit 72 skips the song being played and Play the song. For example, when the menu item selected by the item selection unit 73 is “album”, the reproduction unit 72 reproduces the next song recorded in the album. When the “genre” of jazz is selected by the item selection unit 73, the playback unit 72 rearranges the titles of the songs whose attributes are jazz in ascending order (or descending order) and plays them in order.

  (6) During the reproduction of digital data (music file, moving image data, etc.), if the signal acquired from the motion sensor 23 indicates a forward tilt, the control unit 71 increases the volume (volume). Specifically, the control unit 71 increases the volume step by step each time such a signal is acquired.

  The audio media player 10 may be configured to set a plurality of modes. In each mode, a motion type and a reproduction processing type that are different for each mode are set. For example, in the first mode, motion and playback are performed so that a music file is played when a forward tilt is detected and a music is skipped when a right tilt is detected. The type of playback processing is determined and set. On the other hand, in the second mode, for example, a playback process is executed in which music is skipped when a forward tilt is detected and a music file is played when a right tilt is detected. The type of motion and playback processing is set in.

  According to such a portable media player 10, various functions can be executed with a simpler operation that does not require a button operation. In particular, by tilting the head (neck) to which the earphone 21 is attached, it is possible to execute processing such as playback sensibly, so the portable media player 10 is more user-friendly than complicated button operations. Can be provided.

  Note that the portable media player 10 according to the present embodiment may execute predetermined processing based on the tilt direction detected by the motion sensor 23, movement in a predetermined direction, the number of vibrations, and a combination thereof. For example, when the motion sensor 23 detects a predetermined number of times (for example, three times) of vibration within a predetermined time (for example, within 3 seconds) after detecting a tilt in the right direction, the playback unit 72 displays a music file or the like. May be played.

  In addition, the operation (tilt, vibration, operation direction, etc.) associated with the power-on process and the reproduction process may be set as appropriate. For example, the process data 40 may be stored in a storage medium such as a ROM.

<Second embodiment>
In the above-described embodiment, the motion sensor 23 is built in the earphone 21, but in the second embodiment, a wristwatch-type wristband 100 that is fixed to the wrist is provided as an accessory of the portable media player 10. Then, by incorporating the motion sensor 23 in the wristband 100, a predetermined instruction can be output to the portable media player 10 according to the movement of the arm.

  FIG. 9 is a view showing the wristband 100 according to the second embodiment. A portable media player 10 according to this embodiment includes a main body 11, an earphone 21, and a wristband 100, and the wristband 100 and the main body 11 are connected by a sensor cable 102. In addition, the same structure as 1st embodiment attaches | subjects the same code | symbol, and abbreviate | omits description.

  The wristband 100 has a band main body 101 and a sensor cable 102. The band main body 101 includes a motion sensor 23 and a display 14 that displays processing marks for predetermined processing (playback, stop, etc.). The sensor cable 102 is a communication cable for outputting a signal indicating the tilt direction and output value detected by the motion sensor 23 to the arithmetic processing unit 12 of the main body 11.

  The motion sensor 23 is built in the band main body 101 attached to the arm, and detects the tilt direction and the size of the wristband 100 due to the movement of the arm. Further, the motion sensor 23 generates a signal indicating the detected tilt direction of the wristband 100 and an output value proportional to the acceleration of the operation, and outputs the signal to the arithmetic processing unit 12 of the main body 11 via the sensor cable 102. .

  Note that the portable media player 10 according to this modification has a process acceptance mode set in order to prevent the motion sensor 23 from malfunctioning due to the wristband 100. That is, the control unit 71, the reproduction unit 72, and the item selection unit 73 do not execute a predetermined process such as a reproduction process unless the process acceptance mode has been entered.

  Next, the mode transition process according to the second embodiment will be described. FIG. 10 is an example of a flowchart showing such processing.

  The control unit 71 monitors whether or not a signal for shifting to the process reception mode is acquired from the motion sensor 23 (step S021). Specifically, the control unit 71 acquires a signal indicating that the motion sensor 23 is substantially horizontal, and the motion sensor 23 is moved a plurality of times in the horizontal direction (for example, within 3 seconds) (for example, within 3 seconds). (Twice) It is monitored whether or not a signal indicating a shake motion is acquired.

  When a signal indicating such movement is acquired (Yes in step S021), the control unit 71 shifts to a process reception mode (step S022), and shifts the process to step S023. In addition, since the process after step S023 is the same as that of step S011-step S013 which concerns on the above-mentioned embodiment, description is abbreviate | omitted.

  According to such a configuration, processing such as power-on processing and playback processing can be executed in accordance with the movement of the user's arm. Specifically, the control unit 71 shifts to the process reception mode when the user swings the arm horizontally in the front-rear direction several times in the horizontal direction. Thereafter, when the user tilts his arm to the right, the playback unit 72 plays back digital data such as a music file. If the user tilts his arm leftward, the item selection unit 73 selects a menu item.

  According to the portable media player 10 according to the second embodiment, the power-on process and the playback process can be executed by a simpler operation that does not require a button operation. In particular, since a process such as reproduction can be instructed according to the motion of the motion sensor 23 mounted on the wristband 100, the user can perform a more sensible operation.

  In addition, the inclination direction for shifting to the process acceptance mode and the combination thereof (in the above example, the movement in the horizontal direction + the horizontal direction a plurality of times) are not particularly limited. For example, the control unit 71 has tilted a predetermined number of times (for example, three times) in a predetermined direction (for example, leftward) within a predetermined time after acquiring a signal indicating that the motion sensor 23 is substantially horizontal. May be shifted to the processing acceptance mode. Further, for example, the motion sensor 23 may shift to the process acceptance mode by alternately detecting the inclination in the right direction and the left direction twice.

  In addition, when the control unit 71 acquires a signal indicating the horizontal state of the motion sensor 23 by the user leveling his / her arm in the front-rear direction, the process reception mode may be entered.

<Modification>
In the portable media player 10 according to the second embodiment described above, the reproduction process is performed by the motion sensor 23 built in the wristband 100. However, the process that can be executed in the present invention is limited to the reproduction process described above. It is not a thing. In the portable media player 10 according to the modified example, predetermined arrangement processing is added to the music of the music file to be played in accordance with a signal acquired from the motion sensor 23 of the wristband 100.

  Specifically, the portable media player 10 changes the tempo, key, pitch, and pitch of the music to be played in response to a user instruction via the wristband 100. Further, the portable media player 10 applies vibrato or echo to the music to be played in response to a user instruction via the wristband 100. In addition, the portable media player 10 uses and scratches the sampled phrase in accordance with a user instruction via the wristband 100.

  These arrangements can be realized by an existing effector (which provides an acoustic effect) or an equalizer that can change the frequency characteristics of the audio signal. The effector and equalizer can be realized by existing software. Therefore, for example, the ROM of the portable media player 10 only needs to store software for realizing the functions of the effector and the equalizer.

  FIG. 11 is a diagram showing the arrangement processing data 110. Arrangement processing data 110 is stored in a recording medium such as a ROM in association with an operation 111 (for example, an operation such as a tilt direction or rotation) of the wristband 100 and an arrangement processing 112. Specifically, “acquiring a signal indicating rotation in the right direction” is associated with a process called tempo Up. Also, “acquiring a signal indicating rotation in the left direction” is associated with a process called tempo down. Further, “acquisition of a signal indicating horizontal movement in the upward direction” is associated with a process called a key Up. In addition, “acquire signal indicating horizontal movement in the downward direction” is associated with a process called key down.

  Further, “acquisition of a signal indicating horizontal movement in the left direction” is associated with a process called pitch Up. Further, “acquisition of a signal indicating horizontal movement in the right direction” is associated with a process called pitch down. Further, “acquiring a signal indicating movement in the upper left direction” is associated with a process called pitch Up. Further, “acquire a signal indicating movement in the upper right direction” is associated with a process called pitch down.

  Further, “acquisition of a signal indicating movement in the vertical upward direction after acquiring a signal indicating horizontal” is associated with a process of applying an echo. Further, “acquiring a signal indicating fine vertical movement” is associated with a process of applying vibrato.

  Further, “acquisition of a signal indicating a large vertical movement” is associated with a process of reproducing a sampled phrase. Further, “acquiring a signal indicating movement in the horizontal direction” is associated with a process called scratch.

  Note that the control unit 71 determines a fine vertical movement or a large vertical movement based on the magnitude of the output value of the signal.

  Next, an arrangement process of the portable media player 10 according to the modification will be described. FIG. 12 is a flowchart showing such processing. The arrangement process is started with the reproduction of the music file.

  The control unit 71 monitors whether or not a signal for shifting to the arrangement processing reception mode is acquired from the motion sensor 23 (step S031). Specifically, the control unit 71 acquires a signal indicating that the motion sensor 23 is substantially vertical, and the motion sensor 23 is moved a plurality of times in the vertical direction (for example, within 3 seconds) (for example, within 3 seconds). (Twice) It is monitored whether or not a signal indicating a shake motion is acquired.

  When a signal indicating such movement is acquired (Yes in step S031), the control unit 71 shifts to an arrangement process reception mode (step S032), and shifts the process to step S033.

  In step S033, the control unit 71 monitors whether or not a signal has been acquired from the motion sensor 23. When the signal is acquired (Yes in step S033), the control unit 71 determines whether or not the output value of the signal is larger than a predetermined threshold (step S034). The process proceeds to step S035. On the other hand, when the signal is not acquired from the motion sensor 23 (No in Step S033) or when the output value of the acquired signal is smaller than the threshold (No in Step S034), the control unit 71 moves the process to Step S033. Return and monitor for signal acquisition again.

  In step S035, the control unit 71 performs an arrangement process according to the movement of the acquired signal. Hereinafter, each case of such processing will be described.

  (1) When the signal acquired from the motion sensor 23 indicates a leftward rotation, the control unit 71 outputs an instruction signal for increasing the tempo of the music to the reproduction unit 72. When the signal acquired from the motion sensor 23 indicates a rightward rotation, the control unit 71 outputs an instruction signal for down the tempo to the reproduction unit 72.

  (2) When the signal acquired from the motion sensor 23 indicates an upward horizontal movement, the control unit 71 outputs an instruction signal to the reproduction unit 72 to up the music key. When the signal acquired from the motion sensor 23 indicates a horizontal movement in the downward direction, the control unit 71 outputs an instruction signal to down the music key to the reproduction unit 72.

  (3) When the signal acquired from the motion sensor 23 indicates a horizontal movement in the left direction, the control unit 71 outputs an instruction signal for increasing the pitch of the music to the reproduction unit 72. Further, when the signal acquired from the motion sensor 23 indicates a horizontal movement in the right direction, the control unit 71 outputs an instruction signal for down-ranging the musical piece to the reproduction unit 72.

  (4) When the signal acquired from the motion sensor 23 indicates movement in the upper left direction, the control unit 71 outputs an instruction signal for increasing the pitch of the music to the reproduction unit 72. When the signal acquired from the motion sensor 23 indicates the movement in the upper left direction, the control unit 71 outputs an instruction signal for down-sending the music pitch to the reproduction unit 72.

  (5) When the signal acquired from the motion sensor 23 indicates the movement in the vertical upward direction after acquiring the signal indicating the horizontal level, the control unit 71 sends an instruction signal for echoing the music to the playback unit 72. Output. When the signal acquired from the motion sensor 23 indicates fine vertical movement, the control unit 71 outputs an instruction signal for applying vibrato to the music piece to the reproduction unit 72.

  (6) When the signal acquired from the motion sensor 23 indicates a large vertical movement, the control unit 71 uses a sampled phrase of music. Specifically, every time such a signal is acquired, the control unit 71 reproduces a predetermined phrase sampled in advance in a ROM or the like. That is, the control unit 71 simultaneously reproduces the phrase sampled from the music file being reproduced by the reproduction unit 72 in response to the acquisition of the signal.

  Note that sampling and selection of a phrase that has been sampled may be performed by assigning a predetermined action (for example, moving the arm greatly in the lateral direction or protruding in the front-rear direction).

(7) When the signal acquired from the motion sensor 23 indicates the movement in the horizontal direction, the control unit 71 outputs a scratch instruction signal to the reproduction unit 72.

  According to such a portable media player 10, various functions can be executed with a simpler operation that does not require a button operation. In particular, since music can be arranged according to a signal from the motion sensor 23 built in the wristband 100, the music can be freely arranged and enjoyed while dancing.

  The motion sensor 23 may be mounted only on the wristband 100 with one hand, or may be mounted on the wristband 100 that is a pair with both hands. Further, in the case of the wristband 100 that forms a pair with both hands, different arrangement processes 112 may be associated with the movement of the right hand and the movement of the left hand.

  When the gyro sensor is included in the configuration of the motion sensor 23, the portable media player 10 may execute a predetermined process corresponding to the rotation (twist) direction with respect to the axial direction and the number of times. good. For example, when the reproduction unit 72 acquires a signal indicating that the rotation has been made once in the left direction from the motion sensor 23, the reproduction unit 72 reproduces the music file. Further, for example, when acquiring a signal indicating that the rotation has been performed once in the right direction, the control unit 71 outputs a menu item selection instruction signal to the item selection unit 73.

  In addition, when the motion sensor 23 includes a vibration sensor, the control unit 71, the playback unit 72, and the item selection unit 73 of the portable media player 10 can perform a corresponding playback process according to the magnitude and number of vibrations. May be executed. Furthermore, the control unit 71 and the playback unit 72 may increase or decrease the playback speed of the music file according to the vibration timing (rhythm) acquired from the wristband 100, and a predetermined sound such as a drum sound or a cymbal sound according to the rhythm. May be inserted.

  The operations (the number of vibrations and the combination of the numbers) associated with the power-on process, the reproduction process, and the arrangement process may be set as appropriate, and may be stored in the ROM or the like as the process data 40.

  In the portable media player 10 according to the above-described embodiment and modification, the control unit 71 may output voice guidance indicating the contents of the power-on process, the reproduction process, and the arrangement process to the speaker 22. Specifically, when playing back a music file, the control unit 71 outputs voice guidance indicating the processing content such as “plays back” to the speaker 22. Note that the phrase of the voice guidance may be stored in advance in a recording medium such as the storage device 13.

  In this way, the user can immediately determine whether or not the intended instruction has been executed.

  Moreover, a microphone may be mounted on the portable media player 10 according to the above-described embodiments and modifications so that external sound or the like can be recorded. Specifically, when a recording instruction is received from the user via the motion sensor 23 (for example, by acquiring a signal indicating that the user has moved left and right a plurality of times), the control unit 71 transmits external sound to the storage device 13 or the like. Stored in a recording medium.

  Further, a portable camera such as a CCD (Charge Coupled Device) camera or the like may be mounted on the portable media player 10 according to the above-described embodiments and modifications so that a photograph can be taken. Specifically, when the control unit 71 receives a shooting instruction from the user via the motion sensor 23 (for example, by acquiring a signal indicating that it has moved up and down a plurality of times), the control unit 71 captures an image with the built-in CCD camera. The image data is stored in a recording medium such as the storage device 13.

  Even with such a portable media player 10, various operations can be performed sensibly without the need to operate the operation buttons 15.

  Further, the arrangement processing such as changing the tempo of the music or applying the vibrato is executed according to the movement of the wristband 100 according to the above-described modification, but the present invention is not limited to this. Specifically, the arrangement process may be executed when the motion sensor 23 mounted on the earphone 21 according to the first embodiment described above detects the operation of the earphone 21.

  The portable media player 10 includes a mobile phone, a smartphone, a tablet terminal, and the like as target devices.
