Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial Application Field" The present invention relates to a music reproducing device for reproducing music generally called karaoke.

"Prior Art" Generally used karaoke apparatuses use a cassette tape, a record or a compact disc as a storage medium.

The music information stored in these storage media is in a format in which the music itself is stored in real time, although there is a difference between analog and digital.

"Problems to be solved by the invention" Conventional music reproducing devices such as karaoke have a drawback that the sex for singing cannot be changed.

In other words, when a woman sings a song for men, it is too low to sing, and when a man sings a song for women, it is too high to sing.

Therefore, it is convenient to be able to change the pitch of the music to be reproduced to freely switch between the men's version for women and the women's version for men.

However, the conventional music reproducing apparatus cannot change the pitch of the reproduced sound because the music information is stored in the storage medium in real time and the structure for reproducing the information. Even if the playback speed is changed to change the pitch, the tempo and the length of the sound change, and the image of the music changes at this point, which is not practical.

Although a key controller has been put into practical use as a digital external device, the variable range is limited to about 3 degrees because a large variable range affects sound quality. By the way, it is said that the pitch difference between male and female is 5 degrees.

An object of the present invention is to provide a music reproducing device capable of changing only the pitch from male to female and from female to male without changing tempo and sound length.

"Means for Solving Problems" In the present invention, music score information is stored in a storage medium, this music score information is sequentially read out, and this music score information is given to the sound source section and specified by the sound source section based on the music score information. , Pitch, tone,
A music reproducing device having a structure in which a musical tone signal having a length is generated for each musical instrument and the musical tone signal is emitted as a sound by a loudspeaker is used.

In this music playback device, music information is used for male singing in advance,
Gender information for female singing is stored, a gender indicator for displaying the gender information, a gender input means for inputting a gender change command from the outside to set the gender to be used, and score information from this gender input means When a sex different from the singing gender information stored in is input, a music reproduction having a singing gender switching function is provided by providing a sex conversion means for converting the pitch information included in the score information into the input pitch information of the sex. The device is configured.

According to the configuration of this invention, by inserting the IC card or the like storing the score information into the device, the singing gender information stored in the IC card is read out and displayed on the gender indicator.

If the displayed sex does not match the sex of the person who is about to sing, the sex of the person who wants to sing is input from the sex input means.

If the inputted gender information does not match the gender information added to the score information, the controller converts the pitch information in the score information read from the storage means into the inputted pitch information and transfers it to the tone generator section. Perform an action.

Therefore, according to this invention, it is possible to switch only the pitch without changing the tempo, tone color, sound length, etc., and it is possible to play the male singing music as the female singing music, and vice versa. It is possible to provide a music reproducing device capable of playing.

"Embodiment" FIG. 1 shows an embodiment of the present invention. In the figure, reference numeral 1 indicates a musical score information storage means. The musical score information storage means 1 can be, for example, an IC card or a ROM board, and can be detachably attached to the device so that different musical score information can be arbitrarily exchanged.

Reference numeral 2 indicates a controller constituted by a microcomputer, for example. The controller 2 reads the musical score information from the musical score information storage means 1 and transfers the musical score information to the tone generator 3 to control the musical score information.

The tone generator section 3 has a plurality of musical tone signal generators 3A to 3N. The musical tone signal generators 3A to 3N are provided with the musical score information read from the musical score information storage means 1 for each musical instrument, and each musical tone signal generator 3A is supplied.
From ~ 3N, a musical tone signal having a pitch (frequency) and a length specified by the waveform corresponding to the sound of each musical instrument and the musical notation information is generated at the tempo specified by the musical score information.

The tone signals output from the tone signal generators 3A to 3N are mixed by a mixer 4, and the mixed output signal is given to a loudspeaker 7 composed of an amplifier 5 and a speaker 6 and emitted as a sound from the speaker 6. .

A device that stores musical score information in a memory and generates musical tone signals corresponding to a plurality of musical instrument sounds from a sound source section according to the musical score information stored in the memory to reproduce music is commercially available as an automatic musical instrument player conforming to the MIDI standard. There is.

Here, in order to help understanding of the present invention, the musical score information, the musical score information storage means 1 and the sound source section 3 will be briefly described.

As the musical score information, as shown in FIG. 2, each symbol 601, 602, 603, 604, ... 612 of the musical score for playing music is converted into a predetermined digital code to indicate a digital signal sequence.

The order of conversion into digital symbols is performed for each part. That is, the staff A shown in FIG. 2 is the treble part, staff B.
Is the low temperature part. Generally, the treble part shown on the staff A is played by a musical instrument such as a piano, a guitar, a violin, a flute and a clarinet. In the low temperature part shown in staff B, a rhythm, that is, an accompaniment is generally played by a pitchless musical instrument such as a top cymbal, a hi-hat, and a drum. In this example, two parts are shown as an example.However, depending on the song to be played, a staff of a number corresponding to the number of musical instruments used in the song or the number of chorus parts is prepared. Note symbol 601,
.. are converted into digital codes in order from the beginning.

In other words, after converting all staff A into digital code,
Next, the staff B is converted from the beginning into a digital code, this is repeated for the number of parts, and the digital code is written in a storage means such as an IC card or a ROM board.

FIG. 3 shows an example of musical score information. The meaning of each symbol of the musical score information is as follows.

SOT: Identification code that indicates the beginning of the song, DLG: Identification code that indicates the byte length of the song data, TMP: Identification code that specifies the tempo of the song, ST1 to ST12: Note information for each part, INS: Designation of instrument sound, EOC: end of part, EOT: identification code indicating end of music, the musical score information storage means 1 stores, for example, 24 storage areas M ₁ , M ₂ , M ₃ , M ₄ for each part as shown in FIG. ·· M ₂₄ is provided,
The musical score information is stored in the storage areas M ₁ , M ₂ , M ₃ , M ₄ ... M _{24 for} each part.
Memorized in.

The musical score information written in the storage means 1 is sequentially read in parallel from the head address for each part by the controller 2 constituted by a microcomputer. That is, each storage area
M _1, M _2, M ₃ sequentially reads the start address of · · · M _24, when the start address of all the storage areas M ₁ ~M ₂₄ is read, read the second address is for each storage area To be done. In this way, the information of each part is read out in a time division manner and sent to the tone generators 3A to 3N assigned to each part of the tone generator section 3. Tone signal generator
Two types of 3A to 3N are prepared, one for pitched musical instruments and one for silent musical instruments.

When the musical tone signal generators 3A to 3N receive the musical score information of each part, the musical tone signal generators 3A to 3N decode the musical score information and convert it into musical tone signals having the tone color of each part.

In this way, the tone signal generators 3A to 3N output tone signals according to the score information. This tone signal is output in the form of a pulse-modulated signal of a pulse having a duty ratio of 1 / the number of parts as shown in FIG. 5, so it is smoothed by a filter and converted into a low frequency signal, and then is mixed by the mixer 4. After mixing, the mixed output signal is amplified by the low-frequency amplifier 5, and is emitted as sound from the speaker 6.

Here, in this invention, in such a music reproducing apparatus, singing sex information is added to a part of the score information. For example, as shown in FIG. 6, a recording section 601 for singing gender information 601 consisting of, for example, 2 bits is provided before the score information 600.
As an example of the singing gender information 601, “0,1” can be defined as male singing gender information, “1,0” can be defined as female singing gender information, and “1,1” can be defined as duet information. The example of FIG. 6 shows a case in which a plurality of score information 600 is stored in the score information storage means 1, and desired score information is selected from the plurality of score information and reproduced.

When the controller 2 reads the singing sex information 601, the sex information 601 is decoded, the decoding result is given to the sex display 8, and the score information 601 stored in the score information storage means 1 is the male song. It is displayed whether it is for music or for female singing.
As the display method, for example, when the light source 8A is turned on, the one for men is displayed, when the light source 8B is turned on, the one for women is displayed, and when the light source 8C is turned on, the one for duet is displayed. can do.

On the other hand, the controller 2 is provided with sex input means 9. The gender input means 9 includes a switch 9A for changing the female singing score information to the male singing score information and a switch 9B for changing the male singing score information to the female singing score information. By operating the change switches 9A and 9B, the controller 2 operates the gender conversion means 2A, and the sex conversion means
At 2A, the note information ST1 to ST12 (see FIG. 3) included in the musical score information is sequentially rewritten and transferred to the sound source unit 3.

The note information can be rewritten by subtracting 7 or adding 7 to the numerical value for determining the pitch in the musical score information.

In other words, the pitch difference between the male and female versions is about 5 degrees. A perfect 5th degree is a difference of 7 semitones in the pitch table shown in FIG. Therefore, in order to rewrite the male singing information into the female singing information, it is sufficient to add 7 to the numerical value that determines the pitch and transfer it to the sound source section 3. In addition, to rewrite the female singing information into the male singing information, the pitch is changed. Sound source section 3 by subtracting 7 from the value that determines
You can transfer it to.

For example, as shown in FIG. 7, in order to rewrite the C musical note information for men for female singing, it is necessary to rewrite it in G tone which is increased by 7 semitones clockwise.

Further, for example, in order to rewrite the musical score information for female singing in C tone to the information for male singing, it may be rewritten in F tone which is lowered from C tone by 7 semitones in the counterclockwise direction in the pitch table shown in FIG.

When the duet light source 8C is lit on the sex indicator 8, the inputs of the sex changing switches 9A and 9B of the sex input means 9 are ignored, and the musical score information is transferred to the sound source section 3 as it is and played at the same pitch.

The sex converting means 2A is composed of a microcomputer and software for operating the microcomputer. FIG. 8 is a flow chart showing the outline of the software of the sex conversion means 2A.

[Effect of Device] As described above, according to the present invention, the musical score information for female singing is rewritten to the musical score information for male singing, and the musical score information for male singing is rewritten as female singing musical score information as necessary, and the sound source unit 3 is used. You can transfer to and play for men and women, and for women and men.

Therefore, a man can easily sing a song for female singing.
In addition, women can easily sing songs for men, which is a practical effect.

Further, according to this invention, even if the pitch information is rewritten, other information is not rewritten, so that the tempo, tone color, etc. of the music are reproduced as they are, and the image of the original music is not destroyed.
