Description

The color music installation relates to video equipment and can be used for color accompaniment of musical works in concert halls, discos, and in everyday life.

The prior art device for color accompaniment of musical works by A.S. 1816460 A1, 05/23/1993, containing band-pass input filters, a switch, color sources, displays or labels located next to the light sources.

The disadvantage of this device is that it does not fully reflect the brightness, color of musical works.

The objective of the present invention is to expand the assortment of color musical devices capable of fully reflecting the brightness and color of musical works.

In accordance with the invention, this goal is achieved by the use of a color music installation, including multi-channel frequency filters, in which music signals come from a pickup microphone or by wire,

a screen and colored bulbs, switched on by the corresponding relays, in the circuit of which resistance is installed to ensure a weak glow of the bulbs,

in the circuit of each filter there are capacitors, the output contacts of the capacitors through diodes are connected to the control contact of the transistor, to turn on and adjust the brightness of the light,

at the same time, color patterns are created using a trihedral tube from mirrors, on the input side of which there are light bulbs, and a concave mirror at an angle of 45 ° is installed for display on the screen, or

color patterns are created through reflectors that collect light from light bulbs and direct them to a rotating mirror drum with curved mirrors in the form of semicircles for display on the screen.

The color-music installation contains colored lights of red, yellow, green and blue colors, as well as one ordinary one, switched on by the corresponding relay, in the circuit of which resistance is installed to ensure a weak glow of the lamps, multi-channel frequency filters, capacitors connected to transistors through diodes for switching on and adjusting brightness Sveta. The color music installation also contains a device for creating color patterns on the screen, which can be performed in two versions. In the first case, color patterns are created using a trihedral tube of mirrors, on the one side of which there are colored lights, and on the other, a concave mirror at an angle of 45 °. In the second case, color patterns are created by means of reflectors that collect color rays from the bulbs and direct them to a rotating mirror drum with curved mirrors in the form of semicircles.

The operation of the device is based on the principle that each note has its own color. It has been established that the red color corresponds to the note To, orange - Re, yellow - Mi, Green - Fa, blue - Salt, blue - A, Violet - Si. Between these sounds there are midtones for which the above colors are mixed.

Color music installation works as follows.

Musical signals are fed into multi-channel frequency filters from pickup microphones or by wire. In the event that the signals are weak, they are amplified in low-frequency amplifiers so that the relay can trip. Then the signals are fed to multi-channel frequency filters. Each filter passes without delay only the frequency of one musical sound from all octaves. If the filter receives sound from an adjacent key, it is attenuated and the corresponding bulbs light 1/3 or 2/3 of the glow. For example, the sound of Do arrives at the first of the filters and the red light is on completely. When the sound passes to, the red light is on at 2/3 of the glow, yellow is 1/3 of the glow, and a red-orange color is obtained. When sound Pe is received, the screen should be orange. The incoming signal on the first filter weakens by 2/3 - the red light is on 1/3 of the light, on the second of the filters the signal is weak by 1/3 and the yellow light is on 2/3 of the light. We get the color corresponding to the sound of Re - orange.

The color saturation is regulated by the white light of an ordinary light bulb, for which capacitors are connected to each multi-channel frequency filter, which are connected to the control contacts of transistors with diodes. High-frequency signals pass through them better and the light does not light, and the screen has bright, saturated colors. When passing low-frequency signals, the transistor turns on and adjusts the brightness of the light bulb, on the screen we get diluted colors.

To demonstrate the color patterns on the screen, a long tube with three faces from mirrors is used. On the input side are colored lights. A concave mirror is installed at an angle of 45 ° from the output side. In this case, the device is adjusted in such a way that the patterns of high sounds are placed inside the screen, and the patterns of low sounds are outside. There is also a small motor that moves colored light bulbs, and color patterns to the rhythms of the music move slightly.

Or use reflectors that collect rays of light from light bulbs into one light bunny, which is sent to a mirror octagonal drum, which rotates at a speed of 2-5 r / s. The light from the drum is reflected on the screen, where multi-colored rainbows slowly rise, corresponding to a piece of music.
