Abstract

Device for chromatic representation of the ambient sound, characterized in that it comprises a microphone (mic) that captures the ambient sound and generates an electrical signal, which is amplified by an electronic audio preamplifier circuit (amp1), whose output is filtered to decompose the signal in three subbands, for which passive filters are used: a) a bandpass filter (f2) that provides the media component; b) a low pass filter (f3) that provides the bass component; and c) a high-pass filter (f1) that provides the treble component, attacking each of the outputs of the filters to the respective inputs of the three rgb colors, of at least one rgb led, to get each of the components of the captured sound: bass, middles and treble have assigned a different basic color, red, green and blue (rgb) and therefore the variation of the tone of the sound that is heard becomes a color, depending on the audio frequency band let it be heard (Machine-translation by Google Translate, not legally binding)

Description

Device for chromatic representation of ambient sound

Object of the invention

This document describes a device electronic capable of representing the sound with colored light ambient depending on the audio frequency band. To do this They use the latest RGB type LED light elements generation.

This device finds application in the manufacture of devices for animation in theaters parties or places of fun, and also in small appliances personal use, such as game, fun or decorative elements, which they are illuminated with colored lights, depending on the ambient sound, more specifically of the frequency band of said sound.

Background of the invention

There are currently lighting devices that turn on and off, or simply vary their intensity, in Sound intensity function. However, you don't have reference of any device that also varies the representation  color depending on the audio frequency band.

Description of the invention

In the device of the invention the sound environment is captured by a microphone built into the equipment, the electrical signal from the microphone is amplified by a electronic audio preamp circuit; one time amplified, the signal is filtered to break it down into three subbands, for which passive LC filters are used: a filter low pass that will provide the bass component, a step filter band that will provide the media component and a step filter high that will provide the treble component.

Each of the filter outputs attacks each of the three colors of at least one LED type component RGB For example, the low pass filter output attacks the G component (Green = green) of the RGB module, the filter output band pass attacks the R component (Red = red) of the RGB module and the high pass filter output attacks component B (Blue = blue) of the RGB module.

With this it is achieved that each of the sound components, that is, bass, medium and treble have assigned a different basic color, Red, Green and Blue (RGB), so both and because with these three basic colors you can generate the full range of colors that is able to distinguish the eye human, the variation of the tone of the sound that is heard is converted to any color, depending on the characteristics of the melody or sound that we are listening to.

The main feature of RGB modules is that they are capable of producing any color of the visible spectrum as if it were a single source of light, this is the feature that we used to get to color the Sound from a single light bulb.

This circuit is powered by 12V voltages,  therefore a direct connection with the voltage of domestic power grid and therefore there is no risk of electrocution.

Description of the figures

To complement the description that is being performing and in order to facilitate the understanding of characteristics of the invention, is attached herein descriptive a set of drawings in which, with character Illustrative and not limiting, the following has been represented:

Figure 1 shows a block diagram functionalities of the device of the invention.

Preferred Embodiment of the Invention

As can be seen in the referenced figure  the device for chromatic representation of ambient sound understands:

a) A microphone (Mic.) that picks up the sound environment and generates an electrical signal.

b) An amplifier (Amp1), which amplifies through an electronic circuit the audio signal picked up by the microphone.

c) A series of three filters in parallel, which filter the signal received from the amplifier (Amp1) by separating it into three subbands, for which the following filters are used liabilities:

to.

a band pass filter (F2) that provides the component of media;

b.

a low pass filter (F3) that provides the bass component; Y

C.

a high pass filter (F1) that provides the component of acute

d) At least one LED, type RGB, which receives in the respective entries corresponding to the 3 colors: Red, Green and Blue (RGB), the corresponding signal of the filters that break down the sound signal into: bass, medium and treble; so that each tone is assigned a different basic color: Red, Green and Blue (RGB) and therefore the variation of the tone of the sound that is heard becomes a color, depending on the band of audio frequency that is heard.

e) This circuit has a source of 12V power supply, so it does not require a direct connection to the electrical network, which means there is no risk of electrocution.

In the example shown, 3 LEDs are used, but logically this number is variable, what is important is the number of filters (F1, F2, F3) to be matched with the Three basic colors of an RGB LED.

Once nature is sufficiently described of the invention, as well as a preferred embodiment, for the appropriate purposes that the materials, form, size and arrangement of the elements described may be modified, as long as this does not involve an alteration of the essential features of the invention claimed in continuation.
