Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a music reproducing method and apparatus, a music database system and a music database therefor, and more particularly to a music database system and a music database installed on a moving body such as an automobile.

[0002]

2. Description of the Related Art Conventionally, as a music reproducing device for automobiles,
CD players and cassette decks are common. Of these, it is normal to play the songs recorded on the tape in the cassette deck sequentially as they are. In the CD player, in addition to the method of playing them sequentially, the songs are played randomly or only certain songs are played. There is also a method of selecting and playing.

[0003]

However, there is a demand for listening to a local local song from a large number of songs while driving an automobile or the like. In particular, during long-distance travel, we would like to play the local songs of each region as BGM when traveling in that region, or to preferentially provide the local songs of the driving region in a karaoke service on a sightseeing bus. There is a request.

To meet these demands, in Hokkaido, cassette tapes and CDs containing only local songs from Hokkaido
However, there is a problem that cassette tapes, CDs, and LDs must be edited again for each region, and there is a limit to practical use.

Although it is possible to use such local song tapes as long as only old songs are required, it is impossible to select and reproduce local songs for new songs and the like. Further, it is completely impossible with the prior art as described above to automatically determine the region where the automobile is currently traveling and automatically play the local song as BGM.

Therefore, the first object of the present invention is to make it possible to select and play a piece of music, such as a local song, which is related to a specific region, if necessary. The second purpose of the present invention is to automatically select and play a song that is related to the region / region where the vehicle is currently running.

[0007]

According to the music reproducing method of the present invention, the reproduction data of a plurality of songs are stored in association with the position or area on the map, and the position or area on the map is stored. By designating as a search condition, the music data related to the position or area on the map is searched and reproduced.

Further, a music reproducing apparatus of the present invention for specifically implementing the above method reproduces music data storage means for storing reproduction data of a plurality of music and music data given from the music data storage means. In the music reproducing device including the music reproducing means for reproducing, the map related information storing means for associating the music stored in the music data storing means with the position or area on the map and the position or area on the map are searched. A search condition instructing means for instructing as a condition, and a music selecting means for selecting a music to be given to the reproducing means based on the instructed search condition and the stored contents of the map related information storage means. To do.

According to this music reproducing device, when the position or area on the map is instructed by the search condition instructing means, it is associated with the position or area on the map in relation to the stored contents of the map related information storage means. You can select and play the existing songs. In addition, the position or area on the map may be a unit such as (East longitude *** degree, north latitude *** degree), or (east longitude ** degree ~ ** degree, north latitude ** degree ~ ** degree)
Units such as Also, "Hokkaido", "Tohoku",
Units such as "Kanto" can be used, or "Aichi Prefecture",
Units such as "Gifu Prefecture", ..., Units such as "Nagoya City", "Okazaki City", "Toyota City", ...
It can be any unit that represents a point or area.

In particular, a moving object-installed music reproducing apparatus for achieving the second object stores music data storing means for storing reproduction data of a plurality of music and music data given from the music data storing means. In a mobile body-installed music reproducing device configured to reproduce music on a mobile body such as an automobile, the music stored in the music data storage means and the position or area on the map are reproduced. Based on the relation between the map-related information storage means to be associated, the current position acquisition means for acquiring the current position of the moving body, the current position acquired by the current position acquisition means, and the stored contents of the map-related information storage means, And a music selection means for selecting a music piece to be given to the reproduction means.

According to this device, it is possible to acquire the current position of the moving body by the current position acquisition means and select a song associated with the current position. Therefore, it becomes possible to automatically reproduce a local song or the like in the region while moving. In this case, as the current position acquisition means,
Various devices such as so-called GPS navigation and autonomous navigation for acquiring the position of the moving body can be used.

It is to be noted that, in these music reproducing apparatuses, it is preferable that when the music selecting means selects a plurality of music pieces at a time, it also has an order determining means for determining a reproduction order for the plurality of music pieces. . Further, in this case, it is more preferable to include an order determination condition setting changing unit for changing the setting of the order determination condition by the order determination unit.

This is because, for example, the local song is not limited to one song. When such multiple local songs are selected, the order in which they are played may simply be the order in which the data was recorded. This is because a device with a higher degree of satisfaction can be obtained by sequentially reproducing from the beginning, or in the order of enka, folk songs, popular songs, new music, ... According to the preference of the user. In addition, such a reproduction order may be changed by the user.

On the other hand, when the music selection means selects a plurality of music pieces at a time, a music selection list display means for displaying a list of the plurality of music pieces may be provided. By doing so, the order can be arbitrarily selected from the music selection list. Such a device is particularly promising as a karaoke device installed on a sightseeing bus or the like. That is, it is possible to use the karaoke songs which are related to the region where the bus is running on the display or the like, and the tourist can select a song from these to enjoy the karaoke.

Further, the music database system of the present invention stores music data storage means for storing reproduction data of a plurality of music pieces, music data stored in the music data storage means and a position or area on a map. A song is selected on the basis of the map-related information storage means to be associated, the search condition instruction means for instructing a position or area on the map as the search condition, and the stored search information and the stored content of the map-related information storage means. And a music selection means for performing the selection.

According to this music database system,
Since the music data stored in the music data storage means is associated with the position or area on the map, the music can be selected by designating the position or area on the map. Also,
The music database of the present invention includes a song data storage unit that stores reproduction data for a plurality of songs, and a map-related information storage unit that associates the song data stored in the song data storage unit with a position or area on a map. And is provided.

And in this music database,
The map-related information storage unit associates the first information for specifying a song, the second information for specifying a position or area on the map, and the first information with the second information. The third information for determining the relationship may be stored. With this, as long as the search instruction corresponding to the second information is given,
The first information can be accessed through the third information corresponding to the second information, and the music data related to a specific region can be read from the music data storage unit and used for reproduction. It will be possible.

The file name of the music piece data corresponding to the music piece number displayed in is acquired by referring to the music piece identification table 41. The data of the acquired file name is read from the hard disk 20 to the RAM 5, sequentially transferred to the MIDI reproducing unit 13 to generate an audio signal, amplified by the amplifier 15, and output to the speaker 17.

In the "automatic music selection mode", the position / region conversion table 43 is referred to on the basis of the current position information (latitude / longitude) acquired by the current position recognizing unit 9, and the acquired current position is the area including the position. Convert to data (Hokkaido, Tohoku, Kanto, etc.). Next, the music piece identification table 41 is searched based on the area data, and the music pieces to be played are listed. Then, since the listed music pieces are sequentially reproduced, the file name is acquired from the music piece identification table 41. After that, the data is read from the hard disk 20 to the RAM 5 and M
The audio signal is transferred to the IDI reproducing unit 13 to generate an audio signal, amplified by the amplifier 15 and output to the speaker 17.

The feature of this embodiment lies in the processing of the "automatic music selection mode". Therefore, hereinafter, the processing contents of the "automatic music selection mode" will be mainly described. The operation of the CPU 1 will be described with reference to the flowcharts of FIGS. When the power is turned on, the process starts from S1.

At S1, the RAM 5 is initialized. First, the whole is cleared, and the position / region conversion table 43 and the music piece identification table 41 recorded on the hard disk 20 are loaded on the RAM 52 in the table formats shown in FIGS. 3 and 4, respectively. In subsequent S3, the LED 35 of the panel 11 is turned off to indicate that the initial state after the power is turned on is the "music designation mode". In addition, all 4-digit displays of the 7-segment LED 31 are turned off.

In subsequent S5, it is checked whether or not the LOCAL switch 39 has been pressed. If the depression of the switch 39 is detected, the process proceeds to S7, and if not, the process proceeds to S9. In S7, a subroutine SUB1 for performing a process in the "automatic music selection mode" is called. When the process returns from the subroutine SUB1, the process proceeds to S9.

The processing of the subroutine SUB1 will be described with reference to the flowchart of FIG. In the first step S21, the LED 35 is turned on to indicate that the current operation mode is the "automatic music selection mode". After the same process,
The process moves to S23. In S23, the current position information (latitude / longitude) is acquired from the position recognition unit 9. After the process is completed, S
Move to 25.

In step S25, the current position information (latitude / longitude) acquired in step S23 is converted into area division data by referring to the position / region conversion table 43 loaded on the RAM 5. When the data of the area classification including the current position is acquired, the process proceeds to S27. In S27, FLG1 and FLG2 of all the music piece data are initialized to 0 in the music piece identification table 41 loaded on the RAM 5. Next, referring to the table 41, a song having the same regional data as the regional classification acquired in S25 is searched. The search result is set by using FLG1 of the music piece identification table 41. That is, 1 is set to FLG1 of the song having the same regional data as the current position, and FLG of the song having the regional data other than that is set.
Set 0 to 1. After the search process is completed, the process proceeds to S29.

In S29, it is checked whether or not the number of pieces of music data associated with the area including the current position searched in S27 is zero. If it is zero, the music piece associated with the current position cannot be played, so the process proceeds to S45. If it is not zero, the retrieved music piece is played, and the process moves to S31.

In S31, the music piece identification table 41 loaded in the RAM 3 is referred to, and the music piece data in which 1 is set in FLG1 and 0 is set in FLG2 is searched from the beginning, and the data is searched. For example, the same song data is selected as the next performance song, and the process proceeds to S33. If there is no song data that meets the above conditions, the process proceeds to S45.

In S33, the file name of the song data selected in S31 is obtained by referring to the song identification table 41,
The song data is stored in the song data storage unit 2 of the hard disk 20.
Read from 1 to RAM5. The music data read out to the RAM 5 is sequentially sent to the MIDI reproducing section 13 to convert the music data into an audio signal for reproduction. When the performance of one song is completed, the process proceeds to S35.

At S35, FLG2 of the music piece identification table 41 is set to 1 for the music piece data played at S33 to indicate that the same music piece data has already been played. After the processing is completed, the process proceeds to S37. In S37, it is checked whether or not the LOCAL switch 39 has been pressed during the previous performance, and if it has been pressed, the process proceeds to S45.
If the pressing of the LOCAL switch 39 is not detected,
The process moves to S39.

At S39, the current position information (latitude / longitude) is acquired from the position recognition unit 9 again. After the same process is completed, the process proceeds to S41. In S41, the position / region conversion table 43 loaded in the RAM 5 is referred to and the S
The current position information (latitude / longitude) acquired in 39 is converted into information of the area division. When the area division including the current position is acquired, the process proceeds to S43.

In S43, the area classification up to the previous time and S41
Check whether it matches the area classification obtained in. If they do not match, it means that the region boundary was crossed during the previous performance, and the process shifts to S27 in order to re-search again the music data associated with the updated region division. If they match, the process moves to S31 in order to play the unplayed music data from the music data already searched.

In S45, control is entered when it is detected in S29 that there is no unplayed song in the regional block including the current position, or when the pressing of the LOCAL switch 39 is detected in S37. At S45, LE is executed as the end processing of the automatic music selection mode of the performance music associated with the current position.
The light of D35 is turned off. Subroutine SU after the same process is completed
The process returns from B1 to S9 in FIG.

In S9, it is checked whether or not there is a performance request by designating the music number by detecting the pressed state of the ten keys 33 and the ENTER key 34 on the panel 11. If there is a performance request by designating the song number, the process proceeds to S11. If not, the process proceeds to S5.

At S11, the music number designated by the ten keys 33 is displayed on the 7-segment LED 31, and at the same time,
Identify the file name by referring to the song identification table 41,
The corresponding file is read from the music data storage unit 21 onto the RAM 5, and thereafter, the MIDI reproducing unit 13 reproduces the sound and outputs it through the amplifier 15 and the speaker 17 to perform a performance process.

After the power is turned on by the above processing, LOCA
When the depression of the L switch 39 is detected, the current position can be automatically detected, and a song named after the area including the current position can be played. Further, if it is detected that the LOCAL switch 39 is pressed during the performance of a song named after the current position, after the completion of the performance of one song, the subsequent automatic performance is not performed and the numeric keypad 3 is pressed.
It returns to the "song designation mode" in which performance is performed by designating the number from 3. When the song number is designated by the ten keys 33 and the ENTER key 34 on the panel in the "song designation mode" by designating the song number, the music corresponding to the designated song number can be played.

Next, an on-vehicle BGM reproducing system as a second embodiment will be described with reference to FIG. As shown in FIG. 7, this in-vehicle BGM reproduction system is different in that a display 50 is provided in addition to the hardware configuration of the first embodiment. In addition, as shown in FIG.
1 is different in that two LOCAL1 switches 51 and two LOCAL2 switches 52 are provided.

As for the data, as shown in FIG. 9, the storage method of the regional data is changed as the music piece identification table 55. Specifically, a region flag column is provided from Hokkaido to Kyushu, and 1 is set in this column to obtain regional data. A big difference from the first embodiment is that since the recording method of the regional data is adopted as described above, for example, in the case of a song such as "Port Town Bruce" where a number of local port names appear, there are a plurality of regions. It is possible to record that it is related to.

The position / region specifying table is the same as that of the first embodiment. In the second embodiment,
The feature is that it has a "semi-automatic music selection mode" in addition to the "automatic music selection mode". Below, the processing contents of the CPU 1 will be explained focusing on this characteristic part.

In the second embodiment, as shown in FIG.
After the power is turned on, when the initialization and the panel display initialization are executed in S1 and S3 as in the first embodiment, the process proceeds to S5.
It is checked whether or not the LOCAL1 switch 51 has been pressed. When the depression of the switch 51 is detected, the process proceeds to S7 to call the subroutine SUB1. This subroutine SUB1 is a subroutine for performing the processing in the "automatic music selection mode" which is exactly the same as that of the first embodiment.

On the other hand, if the pressing of the LOCAL1 switch 51 is not detected, the process proceeds to S9, and it is checked whether the LOCAL2 switch 52 is pressed. When the depression of the switch 53 is detected, the process proceeds to S11 to call the subroutine SUB2. This subroutine SU
B2 is a characteristic part of the present embodiment, and is a subroutine for performing processing in the "semi-automatic music selection mode".

The processing of the subroutine SUB2 will be described with reference to the flowchart of FIG. In the first step S71, the current position information (latitude / longitude) is acquired from the position recognition unit 9. Then, the process proceeds to S73, and the position / region conversion table 43 loaded in the RAM 5 is referred to S
The current position information (latitude / longitude) acquired in 71 is converted into data for area classification. When the data of the area segment including the current position is acquired, the process proceeds to S75, and 1 is set to the flag of the same region data as the area segment of the current position, based on the song identification table 55 loaded on the RAM 5. Search for the song you are playing. Next, in S77, it is checked whether or not the number of pieces of music data as the search result is zero. If it is zero, you cannot play a song named after your current position.
The process moves to S45. If it is not zero, the process is left as it is, and the process proceeds to S13 of the main routine.

On the other hand, when there is the corresponding music data, the process proceeds to S79, and the music and the music number of the retrieval result are listed and displayed on the display 50 to show this subroutine SU.
Exit B2. After that, as in the first embodiment, the designation of the song number is confirmed in S13, and if it is designated, the reproduction is executed in S15.

In this way, when there is a song named after the current position, it is displayed in a list on the display 50. Therefore, if the passenger specifies a song number from the list, the passenger is named after the current position. You can select and play your favorite song from the songs.

Next, a third embodiment will be described. Third
The embodiment has exactly the same hardware configuration as the second embodiment, and uses the same table data. In the third embodiment, as shown in FIG. 12, on the operation panel 11,
enka switch 61, popu switch 62, fol
A k switch 63 and a cl switch 64 are provided. These switches 61 to 63 are used to select a plurality of songs in the automatic song selection mode and the semi-automatic song selection mode.
It is used to set / change the priority order according to the genre. Then, the cl switch 64 is used when returning the priority order in the order of song numbers, which is the standard state of the present system.

In this embodiment, as shown in FIG.
Between steps S5 and S7 and between steps S9 and S11 of the embodiment, steps S6 and S10 for calling the subroutine SUB3 are added. Subroutine SU
As shown in FIG. 14, B3 first displays a message prompting the designation of the music selection priority order on the display 50 in the processing of S81 and S83, and waits for any of the switches 61 to 64 to be pressed.

Then, the processing of S85 is executed in accordance with the pressed switches 61 to 64 to set any one of the priority conditions of ensemble priority, popular song priority, folk song priority, and song number order. When the priority is set in this way, the subroutine S
UB1 or SUB2 will be called.

In SUB1, when the song selection in S33 is performed, if, for example, enka priority is designated according to this priority condition, the songs are first selected from the ensemble in ascending order of song numbers. After the enka disappears, the songs are selected in order of song number. Here, the difference between enka, popular songs, and folk songs is
It is decided to distinguish by the description method of the file name.

Further, in the SUB2, when displaying the music selection list in S79, the order of placement from the top of the list is determined according to the designation of the priority condition. For example, if priority is given to enka, the ranking is decided in the order of increasing song number from the enka first, and when there is no enka, the ranking is decided in order of song number.

As described above, in the third embodiment, the priority of reproduction or the ranking of the list in the automatic music selection mode and the semi-automatic music selection mode can be set in accordance with one's own preference, so that it can be expected to be used more hobbyistly. . As is apparent from the above description, according to these examples,
The current position can be acquired by receiving radio waves from GPS satellites, and a song named after the current position can be automatically selected and played by searching the music database MDB, or presented as a song selection list. , It is possible to deeply feel the travel feeling while traveling on a trip.

Although some embodiments of the present invention have been described above, the present invention is not limited to these and can be implemented in various modes. For example, not only the BGM reproduction system but also a car-mounted karaoke system can be implemented.

If the vehicle is equipped with a navigation system based on autonomous navigation rather than GPS navigation, the current position specified by the navigation system may be used for conversion into regional divisions. Alternatively,
It may be configured as a karaoke system for a sightseeing bus that manually inputs the area classification such as “Hokkaido”, “Tohoku”, “Kanto”, ...
