Abstract

PROBLEM TO BE SOLVED: To provide a bodily sensation apparatus for a karaoke device, capable of being simultaneously enjoyed by a large number of people, without restricting their movements. SOLUTION: Play sound outputted from a body device 1 for playing karaoke music and outputting play sound, is mixed by a mixer amplifier 3 with a singing voice inputted from a microphone 4 and outputted from speakers 5. The play sound is taken out from between the body device and the mixer amplifier 3, and a vibration control part 6 extracts the envelope of low-frequency sound parts of the play sound and thereby drives actuators 7 (7L, 7R) to vibrate a stage 8. Delay elements 25L, 25R are inserted in the mixer amplifier 3, in order to synchronize the vibration of the stage 8 by the actuators 7 with the play sound outputted from the speakers 5L, 5R.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a karaoke apparatus provided with a bodily sensation device for allowing a user to feel the performance sound of a karaoke song.

[0002]

2. Description of the Related Art A body sonic jacket or a body sonic chair has been put into practical use as a device for experiencing a sound such as vibration in addition to hearing a performance sound such as a karaoke song. The body sonic jacket is a jacket in which a vibrator is embedded, and the jacket vibrates by a signal synchronized with music input via a cable. The body sonic chair is a chair in which an actuator is embedded so as to vibrate in time with music.

[0003]

However, since the body sonic jacket has a cable connected to the jacket, it has a drawback that it cannot move freely and must be put on its own clothes. Further, the body sonic chair has a drawback that if you are not sitting on the chair, you cannot experience it and cannot dance freely. In either case, there is also a problem that a large number of people cannot enjoy at the same time.

[0004] It is an object of the present invention to provide a karaoke apparatus that is free from movement restrictions and allows a large number of people to experience music at the same time.

[0005]

According to the present invention, there is provided a performance means for generating a performance sound of a karaoke song, and a mixer for mixing a singing voice input from a singing microphone with the performance sound and outputting the result from a speaker. And an envelope extracting means for inputting a performance sound from the playing means and extracting an envelope thereof, and a vibration means for vibrating the stage with the envelope waveform.

According to a second aspect of the present invention, in the first aspect of the present invention, a delay means for delaying a performance sound for a predetermined time is inserted between the performance means and the mixer.

According to the present invention, the karaoke performance sound is extracted before the singing voice is mixed by the mixer, and the stage is vibrated by the envelope. This prevents the stage from vibrating due to the singing voice, so that the rhythm of the music can be accurately sensed. In addition, by vibrating the stage, a large number of people can go up to the stage and experience music at the same time, and can freely move and dance.

Further, in order to synchronize the performance sound output from the speaker with the vibration of the stage, the performance sound output to the speaker is delayed in front of the mixer. Thus, the vibration and the musical sound can be synchronized.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A karaoke apparatus according to an embodiment of the present invention will be described with reference to the drawings. The karaoke apparatus has a function of outputting a performance sound of a karaoke song from a speaker, driving an actuator for supporting the stage based on the performance sound of the karaoke song, and vibrating the stage according to the music. In this way, music on the stage can be experienced by users.

FIG. 1 is a diagram showing the configuration of the karaoke apparatus. The main body 1 of the karaoke apparatus plays a karaoke tune in response to a user request. The karaoke performance sound is composed of a number of parts, but is collected into a two-channel stereo signal and input to the mixer amplifier 3. The singing voice input from the microphone 4 is mixed with the performance sound of the mixer amplifier 3 and output from the stereo speakers 5 (5L, 5R).

On the other hand, the stereo karaoke performance sound output from the main unit 1 is also input to the vibration control device 6. The vibration control device 6 is a device that controls an actuator 7 (7L, 7R) that vibrates a stage 8 on which a user such as a singer rises. Stage 8 is large enough for a plurality of people to climb. The stage 8 may be provided so as to be higher than the surrounding floor, or the actuator 8 may be provided under the floor to make the stage 8 the same height as the surrounding floor.

The vibration control device 6 is provided with a low-pass filter 20 for extracting only a bass portion from the input karaoke performance sound.
(20L, 20R), rectifier circuit 21 (21L, 21R) for extracting only the envelope from the extracted bass signal
And an amplifier 22 (22
L, 22R). The output of the amplifier 22L drives the actuator 7L, and the output of the amplifier 22R drives the actuator 7R. The actuator 7R is provided on the right side of the stage, and greatly vibrates the stage near the speaker 5R. The actuator 7L is provided on the left side of the stage, and vibrates the stage near the speaker 5L greatly.

On the other hand, the mixer amplifier 3 amplifies the singing voice input from the microphone 4 and adds an effector, a mixer 26 (26L, 26R) for mixing the output of the microphone amplifier 24 into a karaoke performance sound, and a mixer 26. Amplifier 27 (27L,
27R), but includes a delay circuit 25 (25L, 25R) for delaying the karaoke performance sound input from the main unit 1 for a predetermined time and inputting it to the mixer 26. This is because the time lag from the vibration control device 6 to the actuator 7 is absorbed to generate sound from the speaker 5 and the stage 8
The delay time may be set to about several hundred milliseconds in accordance with the response of the actuator 7.

In the above embodiment, the stage 8 is only vibrated up and down, but the one shown in FIG. 2 is one that vibrates the stage back and forth and right and left. In FIG. 1A, a stage 8 is supported by a ball caster 9 and can freely move back and forth, right and left. Actuator 7
L is provided left and right from the side of the stage 8, and the actuator 7R is provided front and rear from behind the stage. As a result, the stage 8 is set based on the musical sound of the left channel.
Can be vibrated left and right, and the stage can be vibrated back and forth based on the musical sound of the right channel.

In FIG. 1B, the stage 8 is supported from below by an actuator 7L. Further, the stage 8 and the actuator 7L are mounted on a support 10. The support table 10 is supported by rollers 11 and is movable left and right. Then, an actuator 7R is provided laterally from the side of the support base 10. Thereby, the stage 8 can be vibrated up and down based on the musical sound of the left channel, and the stage can be vibrated left and right based on the musical sound of the right channel.

[0016]

According to the present invention, the stage can be vibrated based on the performance sound of the karaoke, so that the user can experience the karaoke music without restriction on clothes and movements. Also, if you make a large stage, many people can experience it at the same time.

Further, by delaying the performance sound output from the speaker for a predetermined time, it is possible to accurately synchronize the vibration of the stage with the performance sound output from the speaker.
