Description

  The present invention relates to a sound reproducing apparatus that informs a user of music information by converting music information such as a song name and an artist name related to a music file to voice information externally and reproducing the converted voice information.

  As a conventional technique, for example, there is an audio reproducing apparatus that synthesizes music information inside an audio reproducing apparatus and informs the user of the music information as audio before the music starts (for example, Patent Document 1).

  According to this audio playback device, when a song that the user wants to listen to is recorded, accompanying information such as the title and artist name of the song accompanying the song is voiced inside the audio playback device and the song is played back. By reproducing the accompanying information voiced at the beginning of the music, it becomes possible to know the accompanying information without looking at the display unit.

  However, in the conventional audio reproducing apparatus, the music information is reproduced before the music is reproduced, and the user cannot know the music information at an arbitrary time. In addition, since voice is generated inside the audio playback device, a control unit with high processing capability must be used, which increases costs.

  Accordingly, an object of the present invention is to provide an audio reproducing apparatus that can obtain music information during reproduction of music without using a control unit having high processing capability.

  One aspect of the present invention is a reception unit that receives a music file and an audio file in which information related to the music file is voiced from a connected information processing apparatus; and the music file that is received by the reception unit And a storage unit for storing the audio file, a playback unit for playing back the music file and the audio file stored in the storage unit, and a playback signal for the music file and the audio file played back by the playback unit are output. An audio output unit that performs playback of the music file when there is an instruction to play the audio file during playback of the music file, and the music file corresponds to the music file. Provided is an audio reproducing device that reproduces an audio file.

  According to this configuration, it is not necessary to synthesize information related to the music file inside the audio reproduction device, and the audio reproduction device can be made without using a control unit having a high processing capability.

  According to the present invention, it is possible to obtain music information while playing music without using a control unit having high processing capability.

(Operation)
Hereinafter, the operation of the sound reproducing apparatus according to the embodiment of the present invention will be described with reference to FIGS.

  FIG. 4 is a flowchart of a process of creating a compressed music file using a PC in the embodiment of the present invention.

  A user creates a music file such as a CD that the user wants to import into the audio playback device 10 as a compressed music file 602 on the PC 30 (s41). The music information as the accompanying information in the form of text related to the captured compressed music file 602 is acquired from the database on the Internet (s42). The text-formed music information associated with the compressed music file 602 is voiced using a voice synthesis function provided in the PC 30 to create a music information audio file 603 (s43). The created music information audio file 603 and compressed music file 602 are transferred from the PC 30 to the audio reproduction device 10 and the process is terminated (s44).

  FIG. 5 is a flowchart of the music information audio file registration process in the audio reproducing apparatus according to the embodiment of the present invention. This will be described with reference to the schematic structure diagram of the management information file in FIG.

  The compressed music file 602, music information audio file 603, and music information created by the PC 30 are transferred to the audio reproducing apparatus (s51). The song name, artist name, etc. of the transferred song information are associated with the compressed song file 602 and added to the management information file 601, and the operation is terminated (s52). As a result, the management information file 601 is organized in association with the compressed music file 602 as shown in FIG.

  FIG. 7 is a flowchart about the reproduction processing of the music information audio file in the audio reproducing apparatus according to the embodiment of the present invention.

  When the information button 102e is pressed while playing the compressed music file 602 (s71) (s72; Yes), the control unit 204 plays the music information audio file 603 related to the compressed music file 602 from the management information file 601. (S73).

  If the information button 102e is not depressed in step s72 (s72; No), the process proceeds to step s74.

  After the music information audio file 603 is reproduced, it is confirmed whether or not the music reproduction is finished. If it is finished (s74; Yes), the operation is terminated.

  Here, when the music reproduction does not end in step s74 (s74; No), the process returns to step s72 and the processing is continued.

  FIG. 8 is a flowchart about the reproduction processing of the music information audio file when reproduction is stopped in the audio reproduction apparatus according to the embodiment of the present invention.

  When playback is stopped (s81) and the information button 102e is pressed (s82; Yes), the control unit 204 plays the music information audio file 603 related to the compressed music file 602 from the management information file 601 and ends the process. (S83).

  If the information button 102e is not depressed in step s82 (s82; No), the process returns to step s81.

  FIG. 9 is a flowchart about the reproduction processing of the music information audio file in the audio reproducing apparatus according to the embodiment of the present invention.

  When the user depresses the information button 102e, the control unit 204 searches the management information file 601 for a music information audio file 603 related to the compressed music file 602 being currently reproduced (s91). When the search is completed, the reproduction of the compressed music file 602 is paused (s92). After being paused, the searched music information audio file 603 is reproduced (s93). When the reproduction of the music information audio file 603 is completed, the reproduction of the compressed music file 602 is resumed (s94).

(Effect of embodiment)
According to the above-described embodiment, even when the user cannot see the display unit 101 of the audio reproduction device 10, the desired information can be obtained at any desired time.
