Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a karaoke device,
In particular, the present invention relates to a karaoke device that enables a singer and an audience to enjoy karaoke performance together.

[0002]

2. Description of the Related Art A technical problem in a karaoke apparatus is how a singer can easily and reliably sing a melody in accordance with a karaoke accompaniment, and a karaoke singer by a singer can The most important issue is how effectively they can be heard.

Regarding the former of the above problems, in order for the singer to easily sing in accordance with the melody,
When recording a karaoke accompaniment on a recording medium in advance, a melody by playing a musical instrument sound called a so-called guide tone is recorded, and the singer sings according to the guide tone, so that the melody of the melody can be changed. It was known that it was possible to sing karaoke without removing it.

However, even if this guide tone is useful for beginners of karaoke singing,
This is not necessary for a karaoke singing expert, and since the guide tone overlaps with the singing and is heard by the audience, the quality of the singing is degraded, and the latter subject is newly introduced. There was a problem.

For this reason, it has been proposed to reduce the volume of the guide tone as much as possible. However, if the volume of the guide tone is reduced, the volume of the guide tone becomes insufficient.
Beginners were inviting problems that they could not sing well according to the melody or that the timing of singing when singing could not be timed.

In order to deal with such various problems,
A karaoke device disclosed in Japanese Utility Model Publication No. 1-162164 has been proposed.

The karaoke apparatus disclosed in the above publication is further provided with an input means for instructing whether or not to play a guide tone (melody part), and the guide tone is operated by operating this input means. The control signal is given to the controller to instruct whether or not to perform. Then, the controller outputs musical score information for playing the guide tone based on the command signal from the input means to play the guide tone or to play the guide tone. The output of the score information is stopped so that the guide tone is not played.

Therefore, the singer can selectively perform the guide tone or not perform the guide tone by operating the input means.
It was possible to set the beginner to play the guide tone and the expert to not play the guide tone.

[0009]

However, in the karaoke playing device disclosed in Japanese Utility Model Laid-Open No. 162162/1982, a highly skilled and advanced singer sings without performing the guide tone. And can obtain a sufficient singing effect, but for a moderately skilled singer,
As with beginners, they have to play the guide tone and sing, and because the guide tone overlaps with the singing and is heard by the audience, it is evaluated as a beginner's singing, which makes the singer dissatisfied. was there.

Further, when the reason why a beginner cannot sing well due to karaoke accompaniment is analyzed, not only is the melody of the music unclear, but it is difficult to obtain the rhythm,
Or, when the obligato volume is too high, it tends to be difficult to sing. Therefore, there is a problem that a beginner cannot sing well by simply raising or lowering the volume of the guide tone.

On the other hand, in the karaoke accompaniment in which the volume of guide tone, rhythm, or obligato is set according to the beginner's singing skill, an effective karaoke performance that makes the audience hear that the singing is good is performed. There was a problem that it could not be provided.

The present invention has been made in view of the above-mentioned various problems of the prior art, and an object of the present invention is to provide guide tones in a karaoke accompaniment depending on the skill level of the singer. The present invention aims to provide a karaoke device that controls the volume of each part such as rhythm or obligato so that the singer can easily sing along with the karaoke accompaniment regardless of the skill level.

Further, an object of the present invention is for a singer to play the volume of each part such as a guide tone, rhythm or obligato in a karaoke accompaniment in a volume balance that is easy to sing, and for the audience. The present invention provides a karaoke device which plays the volume balance of each part such as guide tone, rhythm or obligato in the karaoke accompaniment so that the karaoke song by the singer can be effectively heard.

Here, the obligato means a part of a melody different from the melody to be sung.

[0015]

In order to achieve the above object, the karaoke apparatus of the present invention comprises accompaniment data reading means for reading accompaniment data composed of a plurality of parts,
A volume setting means for setting the volume of each part constituting the plurality of parts, a volume control means for controlling the volume of each part based on the setting of the volume setting means, and a volume control means for controlling the volume. The output means outputs the accompaniment data read by the accompaniment data reading means according to the volume.

Further, according to the present invention, accompaniment data reading means for reading the accompaniment data composed of a plurality of parts, a plurality of output means for outputting the accompaniment data read by the accompaniment data reading means, and a plurality of these output means. At least one of the output means is provided with a volume control means for controlling the volume of each of the plurality of parts.

[0017]

In the former case of the present invention, the volume of each part of the accompaniment data can be controlled according to the skill level of the singer. Therefore, for beginners, the volume of the guide tone part and the rhythm part is increased and the volume of the obligato part is decreased to set the volume balance so that karaoke singing is easy. On the other hand, for experienced players, the volume of the guide tone part and the rhythm part should be reduced, and the volume of the obligato part should be increased so that the audience can hear the karaoke song effectively. Set to balance.

In the latter of the present invention, a plurality of output means are provided as output means for accompaniment data. Since the volume control means controls the volume of each part of the accompaniment data with respect to at least one of the plurality of output means, the volume of the guide tone part or the rhythm part is increased and the obligato・ Set the volume balance so that it is easy to sing, such as reducing the volume of parts, and use it for accompaniment when a beginner sings. When the other output means is used for the audience, the singer can easily sing the karaoke song, and the audience can also listen to the karaoke performance with good volume balance.
