Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a karaoke apparatus which adjusts a scale according to a singer, and more particularly, it is based on scale data in which a pitch of a vocal part of a selected song is compared with a normal male scale and a female scale. The present invention relates to a karaoke device for converting music data so as to match a predetermined scale.

[0002]

2. Description of the Related Art Conventionally, for example, when a man sings a song of a female singer or a woman sings a song of a male singer, the scale of the song is higher or lower than his own voice. Since it did not fit, it was adjusted by changing to a scale of a level that seems to be appropriate.
That is, the conventional karaoke apparatus is provided with a key control, and the key control adjusts the scale of the song selected and output by the karaoke apparatus. This adjustment of the scale is performed by raising or lowering the scale according to the set value input to the key control, with the scale of the selected and output music as a reference. The key control is set by changing the pitch height in semitone steps.

Therefore, the user of the conventional karaoke apparatus is
If a person with a low voice such as a male tries to sing a song of a woman with a high scale, and if it is judged that the song has a higher scale than his or her own voice, the scale that is judged to be appropriate To lower the scale of the key control, press the flat button to lower the scale of the key control to lower the scale of the selected song. On the other hand, if a person with a high voice such as a woman tries to sing a song with a lower scale, and if it is determined that the song has a lower scale than her own voice, then the scale is raised. Press the button to raise the scale of the song. Then, when the musical piece whose scale has been changed ends, the musical scale returns to the standard again, and when the next person tries to sing, the musical scale is adjusted by pressing various buttons of the key control in the same manner. The scale change by the key control as described above can be changed not only before singing but also while singing a song, each time when the scale of the song is not suitable for one's voice.

[0004]

However, in the key control provided in the conventional karaoke apparatus as described above, the scale changed by judging that the scale is suitable for oneself by changing the scale in semitone steps However, as I thought, I could change it many times without adapting to my voice. In particular, it is difficult to judge whether the scale of the selected song matches the scale of one's own voice. For example, whether a person with a low voice makes a voice at a high pitched part of the song or not. Was difficult to judge. This is because most karaoke users are not familiar with the relationship between the scale of the selected song and the scale that they can utter. Therefore, even if the key control is provided, few people can use it properly, and normally, the key control is often used without changing the scale.

Therefore, it is an object of the karaoke apparatus of the present invention to provide a karaoke apparatus for easily changing the scale of a selected song to a predetermined scale area in order to solve the above-mentioned conventional inconvenience.

Next, the operation of the karaoke apparatus thus constructed will be described. FIG. 3 is a flow chart showing a process of transmitting the musical tone data of the selected music, which is a feature of the present invention, to the MIDI sound source 16, and here, the operation of the scale setting will be particularly described. The scale setting is controlled by the CPU 23 according to the scale setting program 24a of the ROM 24 built in the controller 11. So, first, the karaoke user
A song to be sung is selected by performing a song selection operation on the operation panel 12 of (S1). Then, the scale data of the selected song is read from the hard disk 15 and stored in the data temporary storage memory 25b set in the RAM 25 of the controller 11 (S2). Furthermore, it is confirmed whether or not the key control signal is input (S
3). This key control signal is input by pressing the male voice key 32 or the female voice key 33 on the operation panel 12. In this case, an arbitrary scale may be set by the flat key 34 or the sharp key 35, but such a case is not taken into consideration in the present embodiment.

Therefore, the key control 31 of the present embodiment
For example, if the karaoke user is a man,
When it is determined that the selected song is a female song and the scale is too high to produce a voice, the male voice key 32 of the operation panel 12 is pressed. On the contrary, when it is determined that the music selected by the woman is music by the man and the scale is too low to produce a voice, the female voice key 33 of the operation panel 12 is pressed. Also, when a man sings a song with a lower scale or when a woman sings a song with a higher scale, the male voice key 32 and the female voice key 33 may be pressed respectively, and various modes may be selected depending on the selected song. is there. Then, when it is confirmed that the key control signal is not input (S3: No), the controller 11
The data of the selected song is read from the hard disk 15 and the musical sound data is transmitted to the MIDI sound source 16 as it is (S7).

On the other hand, if it is confirmed that the key control signal is input (S3: Yes), then the scale data stored in the temporary data storage memory 25b is confirmed. That is, it is confirmed whether the scale of the selected song is raised or lowered (S4). And hard disk 1
When the scale data of No. 5 does not indicate any information of "up" or "down" of the scale (S4:
No), hard disk 15 by controller 11
The data of the song selected from is read out, and the musical sound data is transmitted as it is to the MIDI sound source 16 (S7).
On the other hand, when the scale data of the selected song is confirmed (S
4: Yes), the arithmetic program 24b calculates how many scales should be changed to match the scale M or the scale W (S5). Then, the calculation program 24b
Based on the value calculated by the controller 11, the scale of the musical tone data stored in the hard disk 15 is changed by the controller 11 (S6), and the changed data is MI.
It is transmitted to the DI sound source 16 (S7).

If the value of the scale to be changed calculated by the arithmetic program 24b is large, attempting to force it to match the scale M or the scale W will damage the image of the original song. Therefore, if there is a gap of more than a predetermined scale, on the contrary, change the scale in the direction of deviation,
In addition to the data such as "increase" or "decrease", the hard disk 15 has scale data such as "increase one octave" or "decrease one octave" so that the scale is shifted one octave from the scale M or the scale W. Is remembered. Therefore, when a song similar to the above is selected (S
1), the scale data of the selected song is read out and stored in the data temporary storage memory 25b (S2). Then, the change amount is calculated by the arithmetic program 24b so as to be shifted by one octave (S5), and based on the result, the scale of the musical tone data stored in the hard disk 15 is changed by the controller 11 by one octave. (S6), it is transmitted to the MIDI sound source 16 (S7).

Then, when the musical tone data is transmitted to the MIDI sound source 16, the lyrics data which also constitutes the read song data is transmitted to the video mixer 18 and is sent to one of the monitor televisions 3 under the processing described later. It is projected as lyrics. In the MIDI sound source 16 that has received the musical sound data,
The performance signals of the musical instruments are generated by the stored performance sounds of the various musical instruments, and the performance signals of the musical instruments are generated by the musical tone data changed based on the scale data. Then, the performance signal whose scale has been changed is transmitted to the amplifier mixer 4. Also, the song data of the singer is input through the microphone 6 and transmitted to the amplifier mixer 4 similarly to the performance signal, and the voice of the singer is output from the speaker 5 together with the karaoke piece. At this time, the singer can sing while referring to the lyrics displayed on the monitor TV 3. On the other hand, at the same time when the music data is read from the hard disk 15, the video genre data added to the musical sound data is read, the disc player 2 is controlled, and the video reproduction disc of the corresponding video genre is reproduced.

In the video mixer 18, the hard disk 1
The lyrics data read from 5 is synthesized with the NTSC video signal so as to be synchronized with the output of the audio data from the speaker 6, and is transmitted to the video switching circuit 28. By the way, when a karaoke user other than the singer selects to display the list data on the monitor television 3 by operating the remote controller 12a, the controller 11 gives an instruction to read the list data from the karaoke list memory 20. Then, the new song information, the popular song BEST5 at the store, and the requested song order data are read out. The list data thus read is transmitted to the video switching circuit 21.

In the karaoke apparatus of the present embodiment having the above-mentioned structure, it is possible to set the scale suitable for each of the male and female by only one-touch operation of the male voice key 32 or the female voice key 33, and an appropriate scale. It no longer repeatedly raises and lowers the scale before being set to. Further, in the present embodiment, if the highest pitch of the vocal part of the selected song deviates from the scale M or the scale W by a certain amount or more, it is not forcedly adjusted,
On the contrary, the scale is changed by one octave, so it does not spoil the image of the original song, and by shifting by one octave, even if the voice of the scale of the song being played cannot be produced, it is shifted by one octave. By singing in a scale, it is easy to tune with the song being played and you can sing comfortably.

In the karaoke apparatus of this embodiment, the male voice key 32 or the female voice key 33 can be keyed in before or after selecting a song. Further, even if a key is input while the music is flowing, the scale can be changed. Also,
The two keys of the male voice key 32 and the female voice key 33 are used to uniformly adjust the scale based on the scale M or the scale W, but a user who wants to adjust the scale more finely is equipped with a conventional karaoke device. It is also possible to adjust by using the flat key 34 or the sharp key 35 as in the case of the above.

Next, referring to FIG. 4, in the karaoke apparatus of the second embodiment, the musical tone data of the selected song is the MIDI sound source 1.
6 is a flowchart showing a process of being transmitted to No. 6. The karaoke apparatus of the present embodiment has the same configuration as that of the first embodiment, but is characterized in that the scale stored in the hard disk 15 in the karaoke apparatus of the first embodiment. That is, in the data, the number of scales higher or lower than the scale M and the scale W is stored. Therefore, its configuration will be described using the first embodiment.

In the karaoke apparatus of this embodiment, the scale setting is performed as follows. The scale setting is controlled by the CPU 23 according to the scale setting program 24a of the ROM 24 built in the controller 11. Therefore, first, the karaoke user operates the operation panel 12 of the commander 1.
Select the song you want to sing by performing the song selection operation of (S
11). Then, the scale data of the selected song is read from the hard disk 15 and stored in the data temporary storage memory 25b set in the RAM 25 of the controller 11 (S12). Further, it is confirmed whether or not the key control signal is input (S13). Therefore, when it is confirmed that the key control signal is not input (S13: No), the controller 11 reads the data of the selected song from the hard disk 15, and the musical tone data is directly transmitted to the MIDI sound source 16. (S16).

On the other hand, if it is confirmed that the key control signal is input (S13: Yes), then the scale data stored in the hard disk 15 is confirmed. That is, it is confirmed whether the highest pitch of the vocal part of the selected music is higher or lower by comparing with the scale M and the scale W stored in the scale data memory 25a (S14). Then, the scale of the musical tone data stored in the hard disk 15 is changed by the controller 11 based on the confirmed scale difference of the scale data (S15), and the changed data is stored in the MIDI sound source 16
(S16).

If the scale value to be changed is large, if the scale M or scale W is forcibly adjusted, the image of the original song will be damaged. Therefore, also in the present embodiment, when there is a deviation of a certain scale or more, the scale is changed in the opposite direction so that the scale is shifted one octave from the scale M or the scale W to the hard disk 15. The scale of the stored musical sound data is changed (S15), and the changed data is stored in the MIDI sound source 16.
(S16). Then, the selected music piece is reproduced in the same manner as in the first embodiment.

According to the karaoke apparatus of this embodiment, as in the case of the first embodiment, an appropriate scale can be set only by one-touch operation, and in addition, the difference between the scale M and the scale W is stored. Therefore, the scale setting operation can be performed quickly.

Although one embodiment of the present invention has been described above, the karaoke apparatus of the present invention is not limited to that of this embodiment, and various modifications can be made without departing from the spirit thereof. For example, the normal male voice scale and female voice scale may be obtained by taking in the voice data of the person who uses the karaoke apparatus and averaging them.
