Description

  The present invention relates to a karaoke apparatus that performs automatic music selection.

  The music selection operation in a general karaoke apparatus is to check a music number of a desired music with a table of contents in which a music title and a music number are associated with each other, and input the music number from the remote control to the apparatus main body. In addition, a method of randomly selecting and playing music has been proposed.

  On the other hand, a karaoke apparatus having a function of displaying the amount of calories consumed by singing a karaoke song has also been proposed.

  In the above general music selection method, it is troublesome to think about the song to be sung and search for the song number in the table of contents. There was a point. In addition, the conventional random song selection function is a function that simply selects a plurality of songs at random without considering the singer's preferences such as the singer's preference, so the singer's friendliness for the selected song has risen. It was difficult and interesting.

  An object of the present invention is to provide a karaoke apparatus capable of automatically selecting a plurality of karaoke songs without a singer performing individual song selection operations.

This invention stores a plurality of music data for playing karaoke songs, an input means for receiving an operation input including an input of a singer's identification code , and a plurality of karaoke song numbers in order. And a control unit that selects a plurality of karaoke songs at a time in response to a singer's operation input, assigns the identification code to the selected karaoke songs, and registers them in the reserved song list in a lump. The control means performs the karaoke song according to the order of the song numbers stored in the reserved song list, and notifies the singer of the identification code when playing the karaoke song assigned with the identification code. It is characterized by doing.

  In the present invention, a plurality of karaoke songs are automatically selected even if the singer does not perform individual song selection operations. Since the singer does not know which song has been selected, the singer notifies the singer using the singer's identification code when the selected karaoke song is played. Thus, by automatically selecting music on behalf of the singer, the singer can be released from the music selection operation, and a new song with a different taste can be sung. In this case, if vocal data is attached to the karaoke song and the vocalist is automatically output when the singer cannot sing, only the karaoke performance can be performed even if the unknown song is selected. The singer can also practice singing about the vocal output. Moreover, although the range of automatic music selection may be performed from all songs, the possibility of selecting a song that the singer does not know at all becomes low by limiting the genre of the song.

  According to this invention, a singer can automatically select a plurality of karaoke songs without performing individual song selection operations, and the singer can use the singer's identification code when playing the selected karaoke song. So that the singer does not lose track of which song was selected.

  FIG. 1 is a block diagram of a karaoke apparatus according to an embodiment of the present invention. This karaoke device reads out music data stored in a DVD or hard disk 17 set in the DVD changer 4 and inputs the data to the sound source device 18 to form and output musical sounds of karaoke music. The music selection operation in which the user instructs the karaoke device which karaoke song data to select and read is generally performed by transmitting a song number from the remote control device 8 to the karaoke device body 1. Do. In addition, the karaoke apparatus of this embodiment has a calorie selection function for automatically selecting a song that consumes the input amount of calories by singing by inputting the amount of calories the user wants to consume. For this reason, the calorie consumption amount indicating how much calories are consumed by singing the song is stored in the index table in which the song number, song name, genre, etc. are associated.

  In FIG. 1, the karaoke apparatus of this embodiment is a system composed of a plurality of components, and includes a karaoke apparatus main body 1, a control amplifier 2, an audio signal processing apparatus 3, a DVD (digital video disk) changer 4, a speaker 5, and the like.

The control amplifier 2 applies a predetermined effect (vocal effect) to the singing voice, and equalizes and mixes the singing voice and the karaoke performance sound, and then amplifies and outputs them to the speaker 5.

  The audio signal processing device 3 is a device that inputs a singing voice from the control amplifier 2 and applies various effects. Simple effects such as echoes can be applied by the control amplifier 2 alone, but this audio signal processing device 3 performs processing such as correcting pitch shifts and creating and adding harmony songs of other parts. Do. The pitch-corrected singing voice or the newly created harmony singing voice is input to the control amplifier 2 again. Further, in order to detect the pitch and volume of the singing voice when correcting the above-mentioned voice deviation or creating a harmony song, this is input to the CPU 10 as song analysis data. The CPU 10 uses this to score a karaoke song.

 FIG. 2 is a diagram showing the composition of music data for playing karaoke music, the index table, and the reserved music list. FIG. 2A is a diagram showing the composition of music data. The song data includes a header in which the song name, genre, release date, etc. are written, a musical sound track in which performance data is written, a lyrics track in which lyrics data is written, and a back chorus in which back chorus position designation data is written. Track, guide vocal track where guide vocal position designation data is written, peripheral device control track where peripheral device control data is written, guide vocal portion where guide vocal audio data is written, back chorus audio data It consists of a written back chorus. The header is a portion where various data relating to the music data is written as described above, and includes data such as a music title, a genre, a release date, and a performance time of the music. The musical sound track includes a guide melody track storing guide melody data.

  The musical sound track, lyrics track, back chorus track, guide vocal track, and peripheral device control track are all described as sequence data composed of a plurality of event data and timing data indicating the read timing of each event data. Each event data is described in the MIDI format. The sequence program counts timing data at a predetermined tempo clock, and when the count data is counted up, reads the event data that follows it and outputs it to a predetermined processing unit. The timing data may be described by the time from the beginning of the song or by the interval from the immediately preceding event. Since the event data of the musical tone track is data for generating musical tone, it can be described in a general MIDI format. Data other than this is not a normal MIDI message, but this track is also described in a MIDI format as a system exclusive message in order to unify the implementation and facilitate the work process.

  FIG. 2B shows the structure of the index table. The index table is a table for searching for music data corresponding to the user's music selection input. In this index table, index calorie, song number, genre, sex, song name, and actual calorie consumption data are stored for each karaoke song. The actual calorie consumption is the amount of calories that will actually be consumed when the singer sings this song. In addition, this numerical value is displayed by the calorie of a physical unit, and 500 calorie is 0.5 calorie when expressed by Cal (large calorie) which is a unit of calorie of food. This index calorie is a calorie amount that serves as a guide when selecting a song with the calorie song selection function. That is, an index calorie of 500 calories is attached to a karaoke song whose actual calorie consumption is in the range of 450 calories to 549 calories. The song number is an identification code for identifying this karaoke song. The genre is classified into enka, pop, anime, new songs, and so on.

  A single song selection function which is the first calorie selection function will be described. The user inputs the calorie content. The amount of calories input is in units of 100 calories (100, 200, 300,...). The karaoke apparatus searches the index table for karaoke songs whose index calories match the input calorie amount, and displays a list of the song names. The user selects one song from the list.

  Next, the compound music selection function which is a 2nd calorie music selection function is demonstrated. The user enters the total calorie content. This total calorie amount is sufficiently larger than the calorie amount consumed in one song (at this time, the genre may be designated at the same time). Then, the karaoke apparatus selects a plurality of karaoke songs so that the total of the index calories becomes the inputted total calorie amount, registers them in the reserved song list, and plays them sequentially.

  In addition, if you select multiple songs with the multiple song selection function, the same singer will sing continuously if you play this continuously, so put the requested songs of other singers in the reserved song list sign up. And since the singer doesn't know which song was selected by the compound song selection function, the song selected by the compound song selection function is the song and who is the one selected . For example, a symbol (icon) for each user who has performed a song selection operation is determined at the time of song selection operation, and this is displayed together with the song name at the time of song start.

  FIG. 6C shows a reserved music list. In this list, up to 10 requested song numbers can be registered. In addition to storing the icon of the singer who selected the song corresponding to the selected song number, in the case of a song selected by the calorie song selection function, in the order of the song, that is, in what number of all songs Whether or not there is (n / m) is stored.

  3 to 5 are flowcharts showing the operation of the karaoke apparatus, and FIG. 6 is a view showing a display example of the monitor of the karaoke apparatus. FIG. 3 is a flowchart showing the operation in the single music selection mode in which the single music selection function is executed. The operations of the single music selection function and the multiple music selection function described with reference to FIG. 4 are realized by a script executed by the karaoke device, and mode selection and calorie input are performed by pressing buttons displayed on the screen with the remote control device 8. It is executed by selecting with.

  In the single music selection mode, the user operates the remote controller 8 to input the calorie amount (step 101: hereinafter simply referred to as 101). The calorie amount is input in units of 100 calories, and in the case of 500 calories, “5” is input. Further, as shown in FIG. 6A, a plurality of foods (ramen, rice balls, dango) may be displayed, and the singer may select one of them. Then, the calorie amount of the selected food is set as the input calorie amount.

  When the calorie amount is input, the karaoke song that matches the input calorie amount is searched from the index table (102), and the searched song name and song number are displayed in a list on the monitor 6 (103: FIG. 6B). )). The user selects one song from the list (104). When one song is selected, the song number of that song is registered in the reservation list (105). At this time, since it is the single music selection mode, “1/1” is stored in the music order storage area to indicate that it is the first music in the music.

  After that, when the order of the music comes, the music data is read and played. When the performance of this song is finished (106), the actual calorie consumption stored in the index table is displayed (107).

  FIG. 4 is a flowchart showing an operation in the single song selection mode in which a multiple song selection function for selecting a plurality of songs by the total calorie amount is executed. In the multi-tune selection mode, the user operates the remote controller 8 to input the calorie amount (111). The calorie amount input method may be the same as in the single music selection mode. Next, the user selects the genre (112), the calorie consumption curve (113), and the icon (114) of the song. The genre of songs is classified into enka, pops, anime, new songs, etc. as described above. The calorie consumption curve is a curve obtained by graphing the calorie consumption of each song when a plurality of songs selected as shown in FIG. 7 are arranged. As shown in FIG. Curves such as an up type as shown in FIG. 5B and a down type as shown in FIG. Further, the icon is a graphic as shown in FIG. 6C, and the selected icon represents the user who is selecting this compound music. Note that the user ID of the user may be used instead of the icon.

  When the above information is input, the index table is searched based on the total calorie and genre, and a plurality of songs whose sum of index calories is the total calorie amount are selected from the songs of the specified genre (115). Then, the order of the plurality of songs is edited so as to become the selected calorie consumption curve (116), and the list is displayed on the monitor 6 (117). These songs are registered in the reserved song list together with the user ID and the song order (118).

  In this compound music selection mode, a plurality of songs are selected at a time. Therefore, if these songs are registered in the reserved song list at the same time, the same person sings a number of songs continuously. Therefore, in step 118, as shown in FIG. 2C, a plurality of selected songs are registered every other song, and other user's requested songs are registered in the blank order. Good. Also, if the number of selected songs cannot be registered in the reserved song list, the song name and song number of the songs that could not be reserved are stored in other storage areas, and the performance advances and the reserved song list is blank. You can register the remaining songs when you can.

  FIG. 5 is a flowchart showing the performance processing operation of the music registered in the reserved music. When the previously performed music is finished, the first music number in the reserved music list is read (121), and performance preparation for the music is executed (122). If the head of the reserved song list is blank, the song number in the next column is read. The music performance preparation includes an operation of reading music data of the music number from the hard disk or DVD into the RAM and an operation of initializing a sound source so as to form a musical tone of the music. At this time, it is determined whether this song is a reservation with an ID such as an icon that can identify a singer (123). If an ID is added, it is determined whether the ID is the same as the ID of the song played immediately before. (124). If the IDs are the same, the performance is started after the start of the performance is delayed for a certain time in order to make the singer rest (125). During this delay, a message as shown in FIG. In the case of a reserved tune with an ID, an ID is displayed together with the tune name at the start of performance to instruct who is to sing (126: FIG. 6E).

  Thereafter, the performance is started (127), and the voice analysis data obtained by analyzing the voice input in accordance with the performance is input (128). This voice analysis is performed by the voice signal processing device 3, and information such as the pitch and volume of the singing voice is input as voice analysis data. The singing is scored by comparing the voice analysis data with the guide melody data in the performance data (129). When it is found from the input voice analysis data that the singer is not singing at all, the reproduction of the guide vocal is automatically turned on (130, 132). In this embodiment, in the case of a calorie music selection mode in which the singer selects music without directly specifying the song name, there is a possibility that a song not well known by the singer may be selected. The guide vocal is turned on. When there is an input voice, the guide vocal is not turned on even if the pitch is slightly shifted (131). Steps 128 and after are repeated until the music is finished.

  When the music is finished (133), the scoring result is displayed (134), and it is judged whether the scoring result is a predetermined score or more (135). If the score is over a predetermined number, the song is correctly sung and the calorie of this song is consumed (136), and the actual calorie amount of this song is read from the index table and displayed (137), and the song is selected. In the case of the mode song (138), this actual calorie consumption is added to the total calorie consumption storage area (139), a display as shown in FIG. 6 (F) is performed (140), and the operation is terminated. .

  In the above operation, whether or not the calories of the played karaoke song have been consumed is determined by 1/0 based on the scoring result, but it is determined that the proportion corresponding to the score has been consumed and the amount consumed. May be calculated.

  In the calorie selection function, the calorie amount may be input directly by providing a button switch for calorie input on the remote controller.

  Alternatively, an index calorie column may not be provided in the index table, and a karaoke song having a small error between the input calorie amount and the actual calorie consumption amount may be selected.

  Also, this calorie music selection function may be realized as a music selection device dedicated to music selection that is separate from the karaoke device. In this case, the music selection device includes a device for inputting the music selection result to the karaoke device main body like a remote control device.
