In addition, when selecting music that suits the driver's preference, it is highly likely that the same music is selected every time, and only music that gets tired of listening is likely to be provided.

Also, the music you want to listen to changes depending on your mood, and the songs you wanted to listen to today don't want to be heard tomorrow or vice versa. You might want to listen to the song you were playing tomorrow. Therefore, it can be said that the music that the user wants to listen to is preferably selected according to the mood of the user.

However, if the user has to select all the songs, the operation becomes troublesome. In particular, mass storage devices such as HDDs have recently become widespread, and data relating to a large number of songs (for example, 1000 songs) can be stored.
It is not easy to select a desired music from among 00 music. In the future, it is expected to develop a technology capable of selecting a music piece desired by a user without troublesome operation.

For example, recently, as shown in FIG. 6, the data of the music itself recorded on the CDs 2-1 to 2-n (hereinafter referred to as music data) and the TOC (Table Of Contents) are stored in the HDD 1.
) Information (for example, the number of songs and the total performance time), and further information related to the CD (for example, the title name, the number of songs recorded, the total performance time of the recorded songs, the name of the singer, the name of each song) (Song name / performance time) is stored.

For music data and TOC information, read data from CD2-1 to 2-n
What is necessary is just to memorize | store in D1, and since there exists the organization 3 which provides these information about the information regarding CD, the information provided from the organization 3 should just be acquired and memorize | stored in HDD1. In addition, it can be judged from the number of recorded songs and the total performance time whether the information on the CD provided by the institution 3 corresponds to which song data is stored in the HDD 1.
For example, information related to a CD (number of music pieces: 16 pieces, total performance time: 51 minutes and 12 seconds) stored in the first title whose title name is “Large Invention” is stored in the second piece of music data ( C
It can be determined that the data corresponds to the music data recorded in D2-2.

By the way, as described above, if a lot of music can be stored in the HDD 1, it becomes possible to listen to music that suits the user's mood, but simply play the music that the user wants to listen to. Just continuing will not be enough to make driving comfortable and make driving fun. For example, if the introduction of music to be played, such as a song program on television or radio, is performed, the production effect is expected to increase.

The information about the CD (number of music pieces: 16 songs, total performance time: 51 minutes 12 seconds) stored in the second title name is “Large Invention” is stored in the second music data (CD2-2). It can be determined that the data corresponds to (recorded music data).

Next, the processing operation [1] performed by the microcomputer 12 in the music playback device 11 according to the embodiment (1) will be described based on the flowcharts shown in FIGS. This processing operation [
1] is an operation performed when the DJ mode is set. The setting of the DJ mode is determined that the user has issued “DJ mode start” based on information obtained from the microphone 17 by the microcomputer 12, for example. This is performed when the remote controller 15 or the display device 16 is operated by the user and it is determined that the user desires to start the DJ mode.

When the DJ mode is set, first, the guidance sentence data and the song introduction basic sentence data are read from the HDD 25 as an initial setting (step S1). Next, the guidance sentence data corresponding to the guidance sentence at the start of the DJ mode is obtained. By selecting and outputting the selected guidance sentence data to the voice synthesizing unit 18, the guidance sentence is outputted as voice from the speaker 20 (step S2). For example,
A guidance sentence such as “Okay, start playing music in DJ mode” is output from the speaker 20.

Note that there are a plurality of types of basic sentence data for introducing songs, which correspond to each genre, and an example is shown below.
For general songs: “Please enter XXXXX (song name) from XXXXX (singer name) and XXXXX (song title) from the album XXXXX (CD title name). "
For Ballad: “Please enter the ballad from XXXXX (the name of the singer) from the year XXXXX (year of release), XXXXX from the album XXX (title name of the CD)”

Next, a selection condition X (here, a piece of music frequently listened to by the user) for selecting a piece of music is set (step S3), and then the destination G is set using the navigation function. It is determined whether or not (step S4).

If it is determined that the destination G is set, next, a time T required to reach the destination G is calculated (step S5), and based on the time T, the destination G can be heard before reaching the destination G. The number of possible songs (number of music selection C) is obtained (step S6), and then the process proceeds to step S8. For example, assuming that the performance time per song is 5 minutes (including the time for introducing a song), and the time required to reach the destination G is 100 minutes, the number of music selection C is set to 20 songs. . On the other hand, if it is determined that the destination G is not set, the selection number C is set to a predetermined number (for example, 20 songs) (step S).
7) Then, it progresses to step S8.

In step S8, a song that satisfies the selection condition X from the songs stored in the HDD 25 (
That is, the user selects a C song that is frequently listened to recently by the user, and then performs step S1.
Go to 1 (FIG. 4). Although not described in detail here, for the reproduced music, the reproduction date and time is recorded in the HDD 25 in association with the music, and the recent situation in which the user's music is being listened to from this information. Judgment can be made.

In step S11 shown in FIG. 4, the order of the music selected in step S8 (FIG. 3) is set, and then the coefficient k is set to 1 (step S12). In addition, the order of music is, for example,
It can be set at random or set so that the new song released first.

Next, information regarding the kth music is read (step S13), and based on the information, basic sentence data corresponding to the genre of the music is selected (step S14), and the selected basic sentence data and the information are selected. Based on this, song introduction sentence data is created (step S15).
At the time of creation, sentence data related to the reproduction order is added.

Thereafter, the created song introduction sentence data is output to the speech synthesizer 18 to output the song introduction sentence as a voice from the speaker 20 (step S16). For example, “First of all, the song of the patent Taro (name of the singer) released in 2002 (the year it was released)
Patent a (song title) from CD title) ”(first song introduction),“ continue 2
001 (Year of release) Ballet of Big Dipper (singer name) released in year 001, please go to Capricorn (song title) from the album constellation (CD title name) "(the second and subsequent songs introduction)," “Between the Big Dipper (singer name) released in 2001 (year of release), the Capricorn (song title) from the album constellation (CD title name)” (the second song introduction) is output. .

Next, the k-th music is reproduced and the music is output from the speaker 20 (step S17).
. Thereafter, it is determined whether or not the reproduction of the k-th music has been completed (step S18). If it is determined that the reproduction of the music has been completed, then 1 is added to the coefficient k (step S19). Is determined whether or not the song selection number C has been reached (step S20). If it is determined that the coefficient k has reached the number of music selection C (that is, the music to be reproduced next is the last music), the process proceeds to step S31 (FIG. 5). On the other hand, if it is determined that the coefficient k has not reached the music selection number C, the process returns to step S13.

If it is determined in step S18 that the music reproduction has not ended yet, it is next determined whether or not the user wants to end the DJ mode based on the information obtained from the microphone 17 (step S21). ). For example, it is determined whether or not a sound such as “DJ mode end” is issued by the user. If it is determined that the user wants to exit the DJ mode, a message such as “I understand. Then, I will exit the DJ mode. Please call me (agent) when necessary” is output from the speaker 20. (Step S22). On the other hand, if it is determined that the user does not wish to end the DJ mode, the process directly returns to step S17 to continue playing the music.

In step S31 shown in FIG. 5, information on the k-th (last C-th) music is read, and then basic sentence data corresponding to the genre of the music is selected based on the information (
Step S32), song introduction sentence data is created based on the selected basic sentence data and the information (step S33). At the time of creation, related sentence data is added at the end of reproduction.

After that, by outputting the created song introduction sentence data to the voice synthesizer 18, the song introduction sentence is outputted as a voice from the speaker 20 (step S34). For example, “Lastly, the last song of the patent Taro (singer name) released in 2002 (the year it was released) is a good song and the assessment v (song name) from the album invention (CD title name)” Output a sentence.

Next, the k-th (last C-th) music is played and the music is output from the speaker 20 (step S35). Thereafter, it is determined whether or not the reproduction of the k-th (last C-th) song has been completed (step S36). If it is determined that the reproduction of the song has been completed, then “all performances have been completed. This completes the DJ mode. Please call me if necessary, and the guidance sentence is output from the speaker 20 (step S37).

On the other hand, if it is determined in step S36 that the music reproduction has not ended yet, it is next determined whether or not the user desires to end the DJ mode based on the information obtained from the microphone 17 ( Step S38). For example, it is determined whether or not a sound such as “DJ mode end” is issued by the user. If it is determined that the user wants to exit the DJ mode, a guidance message such as “I understand. Then I will exit the DJ mode. Please call me when necessary” is output from the speaker 20 (steps). S39
). On the other hand, if it is determined that the user does not wish to end the DJ mode, the process directly returns to step S36 to continue playing the music.
