DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a karaoke room capable of producing a space where a singer sings and a space where another customer is listening to a singing.

[0002]

2. Description of the Related Art A karaoke box is a typical place for installing a karaoke apparatus. The karaoke box is a private room with a karaoke box installed, and in some cases, a small special stage was installed or a lighting device such as a spotlight or a mirror ball was installed to excite the karaoke singing.

[0003] Also, acoustically, not just an echo,
Filters with reverberation characteristics of various spaces such as halls
In some cases, the sound output from a speaker can be made to have acoustic characteristics as if singing in a place such as a hall.

[0004]

However, the above-mentioned special stage or lighting device merely serves to visually excite karaoke singing, and has the same effect of acoustically exciting singing as a general private room. There was no.

[0005] In the simulation of the reverberation in the above various spaces, the acoustic characteristics that are easy for a singer to sing and the acoustic characteristics that are easy for other audiences to listen to do not always match, and both are satisfactory. It was difficult to set the characteristics. For example, if the reverberation lengthens, the audience will hear well, but the singer will have a problem that the sound image will be blurred and it will be difficult to sing. There was a problem.

An object of the present invention is to provide a karaoke room which solves the above-mentioned problems by forming different sound fields in a singer's space and an audience's space.

SUMMARY OF THE INVENTION The invention of claim 1 of the present application is directed to a karaoke room provided with a karaoke apparatus main body for outputting, from a speaker, an audio signal obtained by mixing a performance sound of a karaoke song and a singing voice of a singer. A singing room in which a singer is present and provided with a singing microphone and a singing room speaker, a guest room in which an audience is present and a guest room speaker is provided, and different sound processing is applied to the audio signal. And an effect device to be supplied to the singing room speaker and the guest room speaker.

The invention of claim 2 of the present application sings a karaoke room in a karaoke room provided with a karaoke apparatus main body which outputs a sound signal obtained by mixing a performance sound of a karaoke song and a singing voice of a singer from a speaker. Of dividing into a singing space having a microphone and a singing speaker and a cabin space having a guest room speaker, applying different sound processing to the audio signal, and supplying the same to the singing room speaker and the guest room speaker. And a canceling device for superimposing on the audio signal a cancel signal for canceling the rounding of the sound output from the other speaker, the canceling device being provided at a stage preceding the singing speaker and the cabin speaker.

According to the first aspect of the present invention, an audio signal obtained by mixing the karaoke performance sound of the karaoke apparatus and the singing voice input by the singer from the microphone is output from the speakers installed in the singing room and the guest room. The singing room and the guest rooms are separate spaces separated by glass and walls. And the setting of the sound effect added to the audio signal supplied to both rooms differs respectively. For example, the setting of the sound effect of the singing room is set to a sound effect like a stage of a hall, and the setting of the sound effect of a guest room is set to a sound effect like a guest room of a hall. This makes it possible to set sound effects that are easy for the singer to sing and for the audience to hear.

According to the second aspect of the present invention, a spatially continuous space is acoustically divided into a singing space and a guest room space. For this purpose, a speaker for a singing space and a speaker for a guest room are installed in each space, and sound signals for which sound effects are set for a singer and an audience are output. However, because of the spatial continuity, the sound comes from the other space. Therefore, an audio signal output as sound is input in the other space, and is superimposed on the audio signal output in the own space so as to cancel this. Thereby, even if the singing space and the cabin space are formed in a continuous space, it is possible to form separate sound fields which do not interfere with each other, and are spatially continuous and different from each other, such as on the stage and in the audience seat. A space with improved acoustic characteristics can be formed.

The music data is stored in a storage device such as a hard disk storage device built in the main device. The background video displayed on the screen 17 and the CRT monitor 26 in parallel with the karaoke performance is reproduced by the video reproduction device 32. The video playback device 32 is an LD changer or a video CD.
It is composed of a changer or the like, and has a built-in storage medium for storing background images of 100 scenes or more. In a normal karaoke performance, a background video that is suitable for this genre is selected based on the genre of the karaoke song. On the other hand, when the singer particularly selects the background video, the video selected by the user is reproduced as a virtual singing space regardless of the genre of the karaoke song. As this virtual singing space,
As shown in FIG. 4, a hall, a live house, a church, a basement, a mountaintop, or the like can be selected.

When the hall is selected as the virtual singing space, the image of the singer taken by the video camera 27 is synthesized with the background image of the stage of the hall and projected on the screen 17. On the other hand, on the CRT monitor 26 of the singing room 2, the image of the customer photographed by the video camera 18 of the guest room 1 may be combined with the background image of the auditorium of the hall and displayed. May be displayed on the background video. In other words, in the former case, the singer can sing as if he were on the stage and singing while looking down at the audience, and in the latter case, the singer could sing while seeing himself standing on the stage. can do.

When the hall is selected as the virtual singing space and the sound field of the hall is formed in the guest room 1 and the singing room 2, the singing room 2 contains the sound field of the acoustic characteristics on the stage of the hall. In the cabin 1, a sound field having the acoustic characteristics of the auditorium of the hall is formed.
