[0041]
Next, the control unit 15 sets the number of music data specified by the user's operation (number of music to be searched Nt) (step S302), and initializes the number N of reproduction candidate songs (step S303). ). Note that the control unit 15 may automatically set a predetermined value for the number of songs Nt to be searched.
[0042]
Next, the control unit 15 sequentially selects music data managed in the reproduction history management table 20 stored in the storage unit 6 using the current position Pos of the vehicle as a search key, and is associated with each music data. The distance D between the reproduction position data being recorded and the current position data is calculated.
[0043]
Next, the control unit 15 determines whether or not the number N of reproduction candidate songs is smaller than the number Nt of songs to be searched (step S305). If this determination is affirmative, the process proceeds to step S306, where reproduction candidate songs are determined. Then, the selected music data is temporarily added to the storage unit and stored as music data of the reproduction candidate music (step S307).
[0044]
On the other hand, when the determination in step S305 is negative (when the number N of reproduction candidate songs reaches the number Nt of songs to be searched), the control unit 15 is associated with the selected music data. It is determined whether or not the reproduction position data is smaller than the reproduction position data farthest from the current position data among the reproduction position data associated with the music data included in the reproduction candidate music (step S308). If this determination is affirmed, the process proceeds to step S309, and the music data associated with the reproduction position data that is farthest from the current position data is deleted from the reproduction candidate songs, and the selected music data is reproduced. A candidate song is temporarily added to the storage unit 6 and stored (step S307).
[0045]
On the other hand, if the determination in step S308 is negative, the control unit 15 proceeds to step S310.
[0046]
Next, the control unit 15 determines whether or not it is the last music data in the reproduction history management table 20 (step S310). If this determination is negative, the next music data is selected, and the processing from step S304 to step S309 is repeated.
[0047]
On the other hand, if this determination is affirmed, the process proceeds to step S311, where the control unit 15 sequentially extracts the music data temporarily stored in the storage unit 6, and the reproduction processing unit 8 reproduces the music data. Then, the process ends.
[0048]
As described above, the music playback device S of the above embodiment designates the number of songs, and is associated with the music data from the music data stored in the storage unit 6 within the number of songs. Since music data that is close to the current playback position and the current position of the vehicle are extracted and played back, music data that is more likely to be viewed at the current position in the past is played back. Therefore, for example, by playing back the music data, it becomes possible to associate a past event that is deeply thought by the user, and it is possible to improve the enjoyment of listening to the user's music.
