Abstract

PURPOSE:To enable new and original production which is not seen before by projecting an image and a text which are selected by a singer on a water film formed by a water film forming device. CONSTITUTION:When the air from an air feed device 11 is mixed with the water from a water feed device 10 and the water is injected from a water film forming nozzle 13B through a drawing member 13, the mixed air becomes extremely fine air bubbles and a white turbid water film screen 6 is formed. The image and text which are selected by the singer can, therefore, be projected on the screen 6 by a projecting means 5, so the singer 9 only sings timing with a melody and rhythm which are reproduced through the sound wave conversion of a speaker 7 over a look at the image projected on the screen 6. Consequently, the degree of an appeal to listeners, the degree of the attraction of singer's attention, and field angle projection effect can greatly be improved.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a karaoke system, and particularly to a karaoke system using a water film screen.

[Prior art] Images and lyrics selected by the singer are projected onto a cathode ray tube or a commonly used sheet-like screen, and the images are converted into sound waves by a speaker and reproduced into the melody and rhythm. Karaoke systems that allow people to sing along are already known.

[Problems to be Solved by the Invention] However, the above-mentioned conventional karaoke system has a problem that the visual direction effect is poor, the appeal to the audience is insufficient, and the attention to the singer is inevitably low. have.

The present invention was developed in view of the above circumstances, and involves projecting images and lyrics selected by the singer onto a water film screen formed by a fountain device, and converting the images into sound waves using a speaker while watching the images. By having the child sing along to the melody and rhythm played,
To provide a novel karaoke system capable of improving the visual performance effect, the degree of appeal to viewers, the degree of attention to singers, etc., that is, a karaoke system using a water film screen.

[Means for Solving the Problems] In order to achieve the above object, the present invention forms a water film screen using a water film forming device, and projects selected images and poetry onto the water film screen using a projection means. At the same time, the video output from the projection means and the audio current corresponding to the poem are converted into sound waves by a speaker and reproduced.

[Function] According to the present invention, the image and the poem selected by the singer are projected onto the water film screen by the projection means, and the melody and rhythm are converted into sound waves by the speaker and played back while the image is being viewed. You can have them sing along.

Images and lyrics selected by the singer are projected onto the water film screen, making it possible to create an unprecedented and innovative performance.

[Example] Embodiments of the present invention will be described below based on the drawings.

FIG. 1 is an overall configuration diagram of an embodiment of the present invention. In the figure, l is a water film forming device, for example, a water supply device 10, an air supply device Mll, and water supplied from these devices l0911. The water supply device 10 includes a high-pressure container 12 that stores air under high pressure and a water film forming mechanism 13.
0A, a high-pressure water pump IOB, and a pump drive motor IOc, and is connected to the high-pressure container 12 via a water supply pipe 3 with a water supply control valve 2 interposed therebetween, and is connected to the inside of the high-pressure container 12.
Water can be supplied from the top, for example in the form of a spray.

The air supply device 11 is composed of a compressor 11A and a motor IIB that drives the compressor 11A.
Water level gauge 12A and pressure control valve 12B are attached, and water level gauge 1
2A to check the internal water level, and the pressure control valve 12B to maintain the internal pressure of the high pressure container 12 at a predetermined value.

The water film forming mechanism 13 includes a throttle member 13A such as an orifice or a throttle valve, and a water film forming nozzle 13B connected to the downstream side of the throttle member 13A. It communicates with the exit 12c. As shown in FIG. 2, the water film forming nozzle 13B is configured by arranging the cylindrical nozzle opening 13bl so as to be directed downward without any gap.

The projection means 5 is a video projector or a movie projector, and is arranged behind the water film screen 6 formed by the water film forming device 1. The video projected on the membrane screen 6 and outputted from the projection means 5 and the audio current corresponding to the poem are converted into sound waves by the speaker 7 and reproduced.

In the figure, 7A is an amplifier, 8 is a singing microphone 9 is a singer.

With such a configuration, the water supply device 1 of the water film forming device 1
0 to the high-pressure container 12 through the water supply pipe 3, and air is supplied to the high-pressure container 12 from the air supply device 11 to maintain the inside of the high-pressure container 12 at a high pressure, so that the pressure is proportional to the pressure. Air can be dissolved in water at a certain concentration, and by opening the throttle member 13A of the water film forming mechanism 13 after setting it to a predetermined throttle amount, the water with dissolved air in the high-pressure container 12 can be dissolved. is ejected from the water film forming nozzle 13B.

Immediately after the water supplied from the cloudy water supply pipe 4 passes through the throttle member 13A, the pressure is rapidly reduced, and as a result, the dissolved air becomes supersaturated and vaporizes, resulting in extremely fine particles with a particle size of several microns to hundreds of microns. The cloudy water jets out from the water film forming nozzle 13B to form a cloudy water film screen 6.

Therefore, the image and the song selected by the singer can be projected onto the water film screen 6 by the projection means 5, so that the singer 9 can hear the sound waves from the speaker 7 while viewing the image projected on the water film screen 6. All you have to do is sing along to the converted and played melody and rhythm.

In this way, the video and lyrics selected by the singer 9 are projected on the water film screen 6, and while watching the projected video, the singer 9 sings along with the melody and rhythm that are converted into sound waves and reproduced by the speaker 7. By realizing the system, the visual performance effect, the appeal to the audience, and the attention to the singer will be greatly improved.
This makes it possible to create innovative performances that have never been seen before, and it can also create a buzz.

In the above embodiment, as shown in FIG. 2, the water film forming nozzle 13B is constructed by arranging the cylindrical nozzle opening 13bl so as to be directed downward without any gap, but as shown in FIG. As shown in the figure, the water film forming nozzle 13B may be configured by arranging the cylindrical nozzle opening 13b1 so as to be directed downward without any gap.

Further, as shown in FIGS. 4A and 4B, the water film forming nozzle 13B can be configured by opening the slit-shaped nozzle opening 13b2 downward or upward. As shown, a water film forming nozzle 13B with a slit-shaped nozzle opening 13b2 opening sideways is placed on a pedestal S, and self-turbid water falls in a waterfall form from the tip of the pedestal S. A membrane screen 6 may also be formed.

[Effects of the Invention] Since the present invention is configured as described above, it produces the following effects.

That is, the image and lyrics selected by the singer are projected onto a water film screen by a projection means, and the image is converted into sound waves by a speaker, allowing the singer to sing along with the reproduced melody and rhythm.

By projecting the images and lyrics selected by the singer on the water film screen, the visual performance effect, appeal to the audience, and attention to the singer will be greatly improved, which is unprecedented. This allows for innovative performances.

Moreover, it can also arouse topicality.
