As shown in FIG. 6, in step S1, it is determined whether there is a keyword that matches the audio file to be reproduced. Specifically, the tag information of the audio file is acquired, and the determination is performed by comparing the tag information with the association between the keyword stored in the storage unit 5 and the display data (see FIG. 3). If there is a keyword that matches the audio file, the process proceeds to the next step S1, and if there is no keyword that matches the audio file, the process proceeds to step S5.
In step S2, it is determined whether or not there are a plurality of keywords that match the audio file. If there are a plurality of keywords that match the audio file, the process proceeds to step S4. If there is only one keyword that matches the audio file, the process proceeds to the next step S3.
In step S 3, display data associated with the matched keyword is displayed on the display unit 1.
In step S4, the data associated with the matched keyword is displayed on the display unit 1 based on the setting of the display method (see FIG. 5 for details).
In step S5, since there is no display data that can be displayed on the display unit 1, reproduction display is not performed.

FIG. 7 shows the tag information of the audio file.
As shown in FIG. 7, the tag information is arranged in the order of title name, artist name, album name, release date, genre, and composer. Note that the user sets keywords based on the tag information.
When a user performs an audio file playback operation, the audio device 100 according to the present embodiment performs a keyword search on the tag information of the audio file, and if a keyword match is found, the keyword ( For example, display data (for example, ABCD.jpg) associated with ABCD is displayed on the display unit 1. The state of the display is shown in FIG.

FIG. 8 is an example of a screen showing how the display data associated with the keyword is displayed on the display unit 1.
As shown in FIG. 8, the artist name “ABCD”, the title name “EFGH”, the track number “01”, and the playback time “00:05” are displayed on the display unit 1, and the display data “ ABCD.jpg "is displayed.
For example, when an audio file having tag information as shown in FIG. 7 is reproduced, since “ABCD” is included in the artist name, a display screen as shown in FIG. 8 is displayed on the display unit 1.
It should be noted that even when another song of the artist “ABCD” is played, the playback display as shown in FIG. 8 can be performed.

  As mentioned above, although concretely demonstrated based on embodiment which concerns on this invention, this invention is not limited to the said embodiment, It can change in the range which does not deviate from the summary.

For example, in the above-described embodiment, the keyword search target is not particularly limited. For example, it may be possible to set only the “artist name” as the search target.
It is also possible not to select a keyword search condition. In that case, all tag information of the audio file is searched for all the keywords.

Further, in the above embodiment, when “(2) Display high priority” is set as the display data display method, the display data with the highest priority is displayed. The display data may be alternately and repeatedly displayed in descending order.
Alternatively, priority may be set for each keyword, and the keywords may be displayed in the order of priority.

  In the above embodiment, when associating a keyword with display data, association is performed for one display data. For example, association is performed for a folder storing a plurality of display data. It may be. By doing so, a plurality of display data can be associated with one keyword.
