Hereinafter, embodiments of the present invention will be described in detail for each example.

FIG. 1 is a block diagram illustrating a music reproducing device according to the first embodiment.
The music reproducing device includes an arithmetic processing device 10, a storage device 20, an acoustic circuit 30, an OK key 33, a skip key 34, a display 35, a USB terminal 36, and the like. The arithmetic processing apparatus 10 includes a memory management unit 11, a data selection unit 12, a reproduction unit 13, an evaluation reception unit 14, an attribute data generation unit 15, and a rule update unit 16. These means comprise a computer program that gives a certain function to a computer built in the music generation device.

  The storage device 20 stores selection rules 21, evaluation information 22, and music data 23. The music data 23 includes, for example, information such as a music title 24, music information 25, a reproduction group 26, evaluation information 27, and reproduction priority 28 as attribute data. The acoustic circuit 30 operates when the music reproducing device reads the music data 23 from the storage device 20 and reproduces it. A speaker 31 is driven by the acoustic circuit 30. The acoustic circuit 30 outputs an acoustic signal to an earphone (not shown) or the like through the connector 32. The skip key 34 is provided for inputting an instruction to stop the reproduction of the music data 23 and play the next music data. In this embodiment, the OK key 33 and the skip key 34 are used to input information indicating user preferences. The display 35 displays the attribute data of the music data 23 and the like.

  The memory management unit 11 in the arithmetic processing device 10 performs control for writing the music data 23 to the storage device 20. It has a function of managing access to the music data 23 written at the same time. The music data 23 is, for example, data downloaded from a personal computer by connecting a USB terminal 36 provided in the music playback device to the personal computer. Control of transferring the music data 23 to this type of music playback device can be realized by various well-known methods. The data selection unit 12 has a function of selecting any piece of music data from various pieces of music data 23 stored in the storage device 20 based on the selection rule 21 and passing it to the playback unit 13 for playback.

  The reproduction means 13 has a function of transferring the selected music data to the acoustic circuit 30 and reproducing it using the speaker 31 or the like. The evaluation receiving unit 14 has a function of receiving input of evaluation information 22 by operating the OK key 33 or the skip key 34 during the music data reproduction process. The attribute data generating unit 15 has a function of recording the evaluation information 22 received by the evaluation receiving unit 14 in the storage device 20 as attribute data of the music data 23. The rule updating unit 16 has a function of updating the selection rule 21 of the music data 23 using the evaluation information as a parameter based on the evaluation information included in the attribute data of the music data 23. Of the attribute information of the music data 23, the music name 24 and the music information 25 are attribute information added in advance by the editing source of the music. The reproduction group 26 is information that is referred to when the music data 23 belongs to a certain group and is reproduced in a batch for each group. The evaluation information 27 is set to the reproduction priority 28 in the example of FIG. The evaluation information 27 does not have to be included in all the music data 23. It may be included only in some groups. Further, it may be included only in a part of music data in the group.

FIG. 2 is a front view showing the appearance of the music reproducing device.
The music reproducing device 40 shown in the figure has a display 35 on the front and an OK key 33 in the center on the lower side. The OK key 33 may also be used as a button that is pressed for confirmation during music selection or other various operations. Of course, you may provide it specially. The skip key 34 is a key operated in order to jump to the next song while playing a song. This may also be used as a key for other functions. A connector 32 is connected to the side surface of the music reproducing device 40 and an earphone 37 is connected. By operating various keys with such a device, it is possible to select music data stored in a storage device such as an internal hard disk and reproduce it like a tape recorder.

FIG. 3 is a hardware block diagram of the music playback device.
As shown in the figure, in the music reproducing device, there are a CPU (Central Processing Unit) 41, a ROM (Read Only Memory) 42, a RAM (Random Access Memory) 43, an HDD (Hard Disk) 44, and an input / output interface 45. Is provided. A display 35, a key 38, and an AMP (amplifier) 39 are connected to the input / output interface 45. The AMP 39 corresponds to the acoustic circuit 30 already described. The functions of the speaker 31 and the connector 32 are as already described. In this music reproducing apparatus, the CPU 41 reads out music data and performs reproduction control according to the operation program stored in the ROM 42. On the other hand, music is selected according to various information stored in the RAM 43, and further data for rewriting the selection rule 21 is temporarily stored in the RAM 43. The HDD 44 stores music data stored in the storage device 20 shown in FIG.

FIG. 4 is a diagram for explaining the operation of the music reproducing device.
As shown in the figure, the music data 23 stored in the storage device 20 (FIG. 1) is sequentially selected by the data selection means 12 according to the selection rule 21 described later. The selected music data is transferred to the reproduction means 13 and reproduced. The time chart shown on the lower side of the reproduction means 13 shows a state where music is being reproduced with time taken on the horizontal axis. If the OK key 33 or the skip key 34 shown in FIG. 1 is operated during the music data reproduction process, an on / off (ON / OFF) signal is received as evaluation information. In this example, for example, a state where the OK key 33 is pressed three times is shown. Each time the OK key 33 is pressed once, the counter 51 owned by the evaluation receiving means 14 increments the count value 52 and stores it.

  At the same time, the evaluation receiving unit 14 reads the system clock 53 and stores the date data 54. The evaluation receiving unit 14 acquires these pieces of information and passes them to the attribute data generating unit 15. The attribute data generation unit 15 generates evaluation information 27 based on the acquired information. This evaluation information 27 is included in the attribute data of each piece of music data 23 shown in FIG. When new evaluation information is thus included in the attribute data, the playback priority of each piece of music data is updated. In accordance with this, the rule updating means 16 updates the selection rule of the music data.

  In this embodiment, the selection rule handles music data in groups. As shown in FIG. 4, the music data has a playback time zone defined for each group. (A) The group is regenerated between 7 am and 8.30 am on weekdays. (B) The group is regenerated between 8:30 am and 9:00 am on weekdays. For example, (a) group has 10 music data, (b) group has 12 music data, (f) group has 8 music data, and so on. The music data reproduced at 8:35 am shown in the example in the figure has a reproduction priority of +3 and is added to the group (b). The rule update means 16 groups music data having the evaluation information 27 as attribute data based on the reproduction time as described above. Within the same group, music data is played in order of playback priority. In the above example, the music data is grouped based on the reproduction time. In addition, the genre can be used as a reference. In this way, the selection rule is generated according to an arbitrary criterion using the evaluation information as a parameter.

  Note that the music data reproduction start command is automatically issued by the reproduction means or by any key operation. The music data is stored in the storage device in units of music such as songs and instrumental performances, and the type thereof is arbitrary. The acoustic circuit is a circuit having a function of reproducing the music so that the user can actually hear it. Arbitrary circuit configurations such as those using a built-in speaker, those using headphones, and those outputting to an external amplifier can be adopted. The user inputs evaluation information during the music data playback process. The input method of evaluation information is arbitrary. It is optimal to press any button provided on the apparatus, but the pressing method and operation method are arbitrary. The reproduction process is in progress from the start of the reproduction process to the end of the reproduction process. If the user's intention is input to the apparatus during this period, the user's intention for music selection is transmitted to the apparatus. When obtaining the number of times the key has been operated, for example, the number of times the key is turned on / off is cumulatively counted. The more you like, the higher the count value. The reproduction start command is automatically issued by the reproduction means or is issued by a predetermined key operation. That is, automatic regeneration or manual regeneration may be used. Conversely, in order to decrement the count value, a skip key for interrupting the reproduction of the music is used. If the reproduction is interrupted while any piece of music data is being reproduced by the reproduction means, the evaluation information of the music data may be updated so as to lower the reproduction priority.

FIG. 5 is a side view of the main part showing a modification of the music reproducing device.
The earphone 60 shown in the figure is attached to the music reproducing device described with reference to FIG. A reproduction vibrating body 62 is provided inside. Here, the sound is played back. Further, a touch switch 61 is provided on the side surface. For example, a push button type switch that is a touch sensor type switch that turns on and off when touched by a finger may be used. It may be on the side of the earphone 60 or on the back. It may be on one ear or on both ears.

FIG. 6 is a connection diagram of the earphone of FIG. 5 and the main unit.
As shown in the figure, an acoustic signal is input to the playback vibrator 62 from the speaker 31 of the music playback device 40 and driven. On the other hand, the output signal of the touch switch 61 is input to the evaluation receiving means 14 of the music playback device 40. The earphone cord may be configured with three sharing the ground line. If you like the song while playing the song data using the earphone 60, touch the touch switch 61 several times. Although it is quite troublesome to press the switch of the apparatus main body or to operate the remote controller, it is extremely easy to touch the earphone 60. Thus, the intention of the user is accurately transmitted to the evaluation receiving means 14.

FIG. 7 is a flowchart of the playback processing operation for one song of the music playback device.
A process of executing a series of processes such as receiving evaluation information and updating a rule when a music piece reproducing apparatus reproduces a music piece will be described with reference to FIG. First, in step S11, an operation key of the apparatus is operated, and an instruction to reproduce a certain song is accepted. In step S12, according to this instruction, the reproducing means 13 transfers the music data to the acoustic circuit 30, and reproduction is started. In step S13, it is determined whether or not the OK key 33 has been pressed for, for example, 1 second or longer. If it has been pressed, the process proceeds to step S14, and the value of the counter indicating the playback priority is cleared to zero. This is processing for clearing the playback priority according to the intention of the user. Thereafter, the process proceeds to step S15.

  If the OK key 33 is not pressed for a long time, the process jumps from step S13 to step S15. In step S15, it is determined whether or not the OK key 33 is turned on once. If turned on once, the counter is incremented in step S16. In other cases, the process of step S16 is skipped. In step S17, it is determined whether or not the skip key 34 is turned on. If the skip key is turned on, the counter value is decremented in step S18. In other cases, the process of step S18 is skipped.

  In step S19, it is determined whether or not the reproduction is finished. If not completed, the process returns to step S13, and the processes from step S13 to step S19 are continued. Thus, the monitoring of the key operation is continued, and when the reproduction ends, the process proceeds from step S19 to step S20. In step S20, reproduction priority information is generated. The counter value may be used as it is as the reproduction priority value. In step S21, time data is acquired. In step S22, attribute data is generated. In step S23, the attribute data is updated. In this way, the music data 23 reproduced now is updated. As described above, when the OK key 33 is turned on, the reproduction priority is raised, and when the skip key is turned on, the reproduction priority is lowered. On the other hand, when playback is performed but no key is pressed, for example, the playback priority may be automatically reset to the initial value, or the playback priority may be minimized. For example, it is possible to perform control such that a song that has been played once has a lower playback priority than a song that has not been played.

FIG. 8 is an operation flowchart when a group is selected and a specific music piece is reproduced.
First, in step S31, an automatic music selection instruction by key operation is accepted. Next, in step S32, a priority group designation is acquired. The priority group is a process of inputting a user's intention such as genre priority, singer priority, and tempo priority and limiting the group to be reproduced by this. In step S33, time data is acquired from the system clock. In step S34, a group in the corresponding time zone is selected. Select the appropriate group according to the conditions such as 8:30 am to 9:00 am on weekdays.

  For example, a group called Japanese pops is selected from 8:30 am to 9:00 am on weekdays. If there are a plurality of selected groups, in step S35, an average reproduction priority is calculated for each selected group. Then, the average points are compared. In step S36, a reproduction group having the highest average score is selected. In step S37, the playback priority of each piece of music data is read for that group. In step S38, the playback order is set for each piece of music data in the corresponding group.

  Thereafter, in step S39, the playback order is displayed on a display or the like. In step S40, the process waits until there is a reproduction instruction from the user. If the user presses the playback button, the process proceeds from step S40 to step S41. In step S41, the reproduction process is started. Each time a group is played, a playback instruction may be waited, or playback may be continued by successively selecting groups in order of playback priority. Also, the first reproduction instruction may be automatically started by a timer, for example.
