Further, when the volume and the frequency reach predetermined values, illumination is performed in a pattern display mode in which the LEDs emit light so as to form a predetermined planar geometric shape.

Therefore, a matrix LED is
Under the control of the light emission control circuit, the device normally operates in the shift display mode, and emits light in a mode corresponding to the volume and frequency of an audio signal output from an audio device such as a speaker. And
Since the number of LEDs corresponding to the sound volume emits light, the number of LEDs emitted or the entire light amount changes in accordance with the volume of the sound output from the audio device. At the same time, since the LED emits light in a color corresponding to the frequency, the color of the LED changes according to the pitch of the sound output from the audio device.

Then, the LEDs in the lowermost position are sequentially illuminated in a bar graph form from the upper LEDs to the upper LEDs, and the lighting state is sequentially shifted to the right column,
The emission colors of the LEDs that light up in the same column are individually determined.

Therefore, in the shift display mode, the number of LEDs proportional to the volume is lit by the control of the light emission control circuit, and the lit LEDs are arranged in a bar graph form from the lowest position to the upper position. Light. Further, the display state of the bar graph is sequentially shifted to the right column. In addition, since LEDs that are lit in the same row can be individually set to different lighting colors, illumination can be performed by various combinations of colors.

FIG. 9 is a timing chart showing the output of the controller of the sound illumination device according to one embodiment of the present invention.

In the present embodiment, the controller 41
The light emission display of the LED matrix 10 is performed by combining the shift display mode shown in FIG. 4 and the pattern display mode shown in FIG. In the present embodiment, the controller 41
Normally, the LED matrix 10 is illuminated in the shift display mode, and is illuminated in the pattern display mode at a specific time. At this time, the controller 41
Control is performed by detecting an electric signal (music signal or sound signal) corresponding to an acoustic signal output from an acoustic device such as the first audio device. For example, the controller 41 detects the volume and frequency of the music signal, and controls the LED 13 in a manner corresponding to the volume and frequency.
Is driven to emit light.

Here, the shift display mode is a normal display mode, and the controller 41 determines the number of LEs corresponding to the volume of the acoustic signal among the LEDs 13 arranged vertically in the same row.
D13 emits light, and the LED 13 emits light of a color corresponding to the frequency of the acoustic signal. Further, the controller 41 performs illumination by sequentially shifting the light emitting state of the LEDs 13 in the row to the next row. In detail, the controller 41
Turns on the LEDs 13 of the number of lamps corresponding to the volume of the music signal in a color corresponding to the frequency. For example, controller 4
1 illuminates the LEDs 13 arranged vertically in the same column in the form of a bar graph from the LED 13 in the lowest row to the LED 13 in the upper row in order in proportion to the volume of the music signal, and changes the lighting state from the left column to the next. Are sequentially shifted at a fixed period to the right column. At the same time, the controller 41 turns on L in the same row.
The emission color of the ED 13 is individually determined.

In FIGS. 4 and 5, a white circle indicates an unlit LED.
13 and the solid circles indicate the lighting LEDs 13. D1
To D8 are L constituting each row of the LED matrix 10.
3 shows the position of the ED array 11 or the LED 13 in the column direction.
In the shift display mode of the present embodiment, as shown in FIG. 4, the LED 13 in the bottom row D1 to the LED 1 in the top row D8
3, the LED 13 is lit in a bar graph. FIG.
From the middle, rightmost column to leftmost column, 1, 3, 5, 1,
Two, one, eight, and three LEDs 13 are lit, respectively, and the lit LEDs 13 in each row in this state are sequentially shifted from the left column to the right column. As a result, it is possible to perform illumination or display that is linked or matched with the sound that changes one after another.

More specifically, as shown in FIG. 6, the controller 41 controls the amplitude VH of the music signal (corresponding to the volume of the sound).
And the wavelength VW or the frequency (corresponding to the pitch of the sound). At this time, the volume VH is a constant cycle, for example, 1 m
The determination is made based on the peak voltage at s, and the frequency or the wavelength VW is determined based on a constant cycle, for example, an average half wavelength within 1 ms. Then, based on the detected volume VH, the number of lighting of the LEDs 13 in the same column is selected, and based on the wavelength VW to the frequency, the emission color of each lighting LED 13 is selected.

For example, as shown in FIG. 7, the controller 41 determines the number of lighting of the LED 13 in nine steps from 0 to 8 in proportion to the volume of the music signal or the peak voltage VH. Note that the voltage and the number of lamps in FIG. 7 are merely examples, and other voltages and the number of lamps may be used. Further, as shown in FIG. 8, the controller 41 determines the lighting color of the LED 13 among six colors of red, yellow, green, light blue, blue, and purple according to the frequency to the wavelength VW of the music signal. FIG.
, Horizontal bars illustrated to the right of the three primary color LEDs (R, G, B) indicate the frequency range of the music signal in which the LEDs of that color are turned on. For example, in a frequency range of about 50 Hz or less, purple light is emitted by mixing colors of a red LED and a blue LED. In the frequency range exceeding about 2000 Hz, only the red LED is turned on. Thus, light emission of only each color or light emission of a mixed color thereof is performed according to the frequency range of the music signal.

At this time, the wavelength VW of the music signal and the LED1
The three wavelengths are associated with each other so as to have a certain correlation. That is, in FIG. 8, light having a short wavelength is made to correspond to a music signal having a long wavelength VW. However, conversely, light of a long-wavelength color may correspond to a music signal of a long wavelength VW. In addition, the emission colors in FIG. 8 are merely examples, and six colors can be freely emitted by a combination of three primary color LEDs. However, it is needless to say that other emission colors may be prepared. May be increased or decreased.

The control operation in the shift display mode will be described with reference to the timing chart of FIG. 9. First, the controller 41 first generates the clock signal CLK shown in FIG.
9B, the data signal DATA shown in FIG. 9B is output to the shift register driver of each LED array 11 as a serial signal. In FIG. 9B, the Arabic numeral "1"
８8 ″ indicate the lamp numbers sequentially assigned to the eight LEDs 13 of each LED array 11 from the left LED 13. In other words, the data signal DATA is in the order from the bottom row D1 to the top row D8. For each lamp number "1"
The LED 13 is output in correspondence with the 8 "LED 13. The data signal DATA for driving the LED 13 of each lamp number includes an RGB signal indicating ON / OFF of the chip LED of each color. In FIG. The numeral “0” represents a dummy signal, and is inserted for the purpose of, for example, separating the data signal DATA for driving each LED array 11.

Each shift register driver is shown in FIG.
In synchronization with the latch signals LACH1 to LACH8 shown in FIG.
Data signal DATA for driving corresponding LED array 11
Take in. The latch signals LACH1 to LACH8 are dummy signals that separate the data signals DATA for driving the LED arrays 11 corresponding to the LED arrays 11 in each row from the LED array 11 in the bottom row D1 to the LED array 11 in the top row D8. Output at the timing. As a result, the corresponding data signal DATA is taken into the shift register driver of the LED array 11 of eight rows D1 to D8 in total. Then, each shift register driver performs serial / parallel conversion of the fetched data signal DATA, and controls light emission of the LEDs 13 (lamp numbers 1 to 8) of the LED array 11 in the corresponding row.

In this manner, from the LED array 11 on the bottom row D1 to the LED array 11 on the top row D8,
The LEDs 13 corresponding to the entire screen of the matrix 10 are controlled to emit light. Note that the enable signal E shown in FIG.
NABLE is the first latch signal LACH1 after power-on.
To "L" to turn on, and to "H" by power-off to turn off.

On the other hand, the pattern display mode is a specific display mode, and the controller 41 forms a predetermined planar geometrical shape as shown in FIG. The LED 13 emits light so that the display is different from the display in the shift display mode.
Specifically, the controller 41 previously stores the LE in the memory.
A large number of lighting patterns of D13 are stored as data. Further, the controller 41 corresponds to each lighting pattern,
The lighting order and emission color of the LED 13 are stored as data. That is, in each lighting pattern, the plurality of LEDs 13 are sequentially lit in a predetermined order and in a predetermined color, and the lighting pattern is finally displayed. Then, when the music signal has a specific combination of volume and frequency, a specific lighting pattern is selected, and LE is displayed so that the lighting pattern is displayed.
D13 is controlled to emit light. Thus, it is possible to insert a display different from the display in the shift display mode at an appropriate timing and change the overall illumination.

As described above, the sound illumination device according to the present embodiment employs LEDs arranged in a matrix.
13 and a controller 41 as a light emission control circuit that controls light emission of the LED 13 in conjunction with an acoustic signal of an audio device such as a speaker 51. Usually, the LEDs 41 arranged vertically in the same row by the controller 41 are used.
3 LEDs 13 corresponding to the volume VH of the acoustic signal
And emits the LED 13 in a color corresponding to the frequency or wavelength VW of the acoustic signal, and illuminates in a shift display mode in which the emission state of the row is sequentially shifted to the next row. Further, the volume VH and the frequency or wavelength V
When W reaches a predetermined value, illumination is performed in a pattern display mode in which the LED 13 emits light so as to form a predetermined planar geometric shape.

Therefore, the LEDs 13 in a matrix form
Operates normally in the shift display mode under the control of the controller 41 as a light emission control circuit, and emits light in a mode corresponding to the volume VH and the frequency or the wavelength VW of the audio signal output from the audio device such as the speaker 51. Since the number of LEDs 13 corresponding to the volume VH emits light, the number of LEDs 13 emitted or the total amount of light varies according to the volume of sound output from the audio equipment. At the same time, LED13
Emits light in a color corresponding to the frequency or the wavelength VW, so that the color of the LED 13 changes in accordance with the pitch of the sound output from the audio device. On the other hand, the LED 13
, The device operates in the pattern display mode at the timing when the volume VH and the frequency or the wavelength VW become the predetermined values, and emits light so as to draw a predetermined planar geometric shape as a whole.

As a result, the LEs arranged in a matrix
By D13, it is possible to perform various illuminations that are correlated with the music that is played,
The synergistic effect of the musical effect and the visual effect can be maximized. In other words, not only enjoy listening to music,
You can enjoy watching the illuminations (sound illuminations) linked to the music. Further, the sound illumination can be displayed so as not to get tired of looking.

Further, in the shift display mode, the light emission state of the first column is sequentially moved (shifted) to the next column without change. The light emitting state is maintained. That is, even if the light emitting state of the LED 13 lasts only a short time in the same column, the light emitting state can be displayed in a form that lasts for a certain time by shifting the light emitting state in the row direction. can do. As a result, it is easy to respond to the display with eyes, and the visual effect by illumination can be enhanced.

When the volume VH and the frequency to the wavelength VW reach predetermined values during the shift display mode, the controller 41 switches the light emission mode of the LED 13 to the pattern display mode. Then, the LED 13 at a position corresponding to the pattern is illuminated so that a predetermined planar geometric shape or pattern can be drawn. Therefore, the display by the light emission of the LED 13 can be changed at a predetermined timing. As a result, the visual effect of the illumination can be further enhanced. Note that the controller 41
As described above, the control of the number of light emission of the LED 13 and the control of the emission color are simultaneously performed.

In the sound illumination device according to the above-described embodiment, in the shift display mode, the LEDs 13 arranged vertically in the same column are controlled by the controller 41 as the light emission control circuit in proportion to the volume VH of the sound signal. The upper LED 1 in order from the lowest LED 13
The LED 13 illuminates in the same column while being illuminated in a bar graph shape to 3, sequentially shifting its illumination state to the right column.
Are individually determined.

Therefore, in the shift display mode, under the control of the controller 41, a number of Ls proportional to the volume VH are set.
While the ED 13 is turned on, the lighting LED 13 is turned on in the form of a bar graph from the lowest one to the upper one. Further, the display state of the bar graph is sequentially shifted to the right column. As a result, the bar graph-shaped lighting LED 13 shifts from left to right, so that the shifting display can be easily followed by eyes, and the visual effect by illumination can be improved.

Further, since the LEDs 13 that are lit in the same row can be individually set to different lighting colors, illumination can be performed by various combinations of colors. As a result, the visual effect of the illumination can be further improved.

Further, in the sound illumination device according to the present embodiment, the controller 41 as the light emission control circuit controls the LED 1 in the pattern display mode.
3 are sequentially turned on in a predetermined order, and the planar geometric shape is displayed as a whole by light emission, and the light emission color of the LED 13 is individually determined.

Therefore, since the pattern is displayed by the LEDs 13 which are sequentially turned on, a unique illumination is obtained. Further, since the LEDs 13 to be turned on can be individually set to different lighting colors, illumination can be performed by various combinations of colors. As a result, the visual effect of the illumination can be further improved.

In the above embodiment, the controller 41 as the light emission control circuit turns on the LEDs 13 in a bar graph in a number proportional to the sound volume VH. L corresponding to VH
Any configuration can be used as long as the number of light emission of the ED 13 is controlled. For example, when the volume VH of the acoustic signal is in the minimum range, the number of light emission of the LEDs 13 arranged vertically in the same row is set to zero or a small number of one or more, and the number of light emission increases as the volume increases. Can be controlled.

At this time, in addition to displaying a bar graph in which the LEDs 13 in the same column sequentially increase from the bottom row to the top row and emit light, an inverted bar graph which sequentially increases and emits light from the top row to the bottom row It may be displayed as a letter. Alternatively, the display may be such that the light is emitted by sequentially increasing in the up and down directions from the intermediate point. Further, the shift direction of the lighting LEDs 13 in each column in the shift display mode may be from the left end to the right end, or may be from the right end to the left end.

Contrary to the above operation, when the volume VH of the sound signal is low, all the LEDs 13 may emit light, and the display may decrease in number as the volume VH increases. That is, the present invention can adopt any display mode as long as the display is to increase or decrease the number of light emission of the LEDs 13 in the same row in accordance with the volume VH.

In the above embodiment, the number and color of light emitted from the LEDs 13 in the same row arranged in the vertical direction are controlled to shift the light emission state of the row to the next row. A configuration may be adopted in which the number of emitted light and the emission color of the LEDs 13 in the same row are arranged and the emission state of that row is shifted to the next row. In this case, the LEDs 13 on the same row
From the leftmost column to the rightmost column, or from the rightmost column to the leftmost column,
Alternatively, a bar graph display may be provided in the row direction from the middle to both sides. In the case of the bar graph display in the row direction, the lighting LED of each row in the shift display mode
The shift direction of 13 may be from the upper end to the lower end,
It may be from the lower end to the upper end.

That is, the illumination device of the present invention
The shift direction may be either the row direction (left-right direction) or the column direction (up-down direction). In short, the illumination device of the present invention rotates the whole by 90 degrees,
Since the column direction of the LEDs 13 arranged in a matrix is the row direction, and the row direction is the column direction, the meanings of “column” and “row” used in the specification are relative.

Further, when the light emission control circuit of the present invention controls the emission color of the LED 13 based on the frequency of the audio signal in the shift display mode, the frequency of the audio signal and the frequency of the emission color of the LED 13 are proportional or inversely proportional. What is necessary is just to control the light emission color of LED13 so that it may respond. Specifically, at a high acoustic frequency, a color having a high color frequency, for example, red can be emitted. At a low acoustic frequency, a color having a low color frequency, for example, purple can be emitted. Of course, the reverse is also possible. In this case, all of the LEDs 13 may emit light of the same color, or may emit light of different colors individually. That is, as long as the frequency of the acoustic signal and the frequency of the emission color of the LED 13 have a specific correlation, the LED 13 can be set to emit light of an arbitrary frequency with respect to the frequency of the acoustic signal.

In addition, in the light emission control circuit of the present invention, in the pattern display mode, one or more LEDs 13 may emit light in a predetermined order in order to finally display a predetermined pattern. Alternatively, the LED 13 may emit light at a time to display a predetermined pattern. Further, the emission colors of the LEDs 13 may be all the same color, or may be individually determined for each LED 13 and may be different colors.

The light emission control circuit of the above embodiment directly inputs the volume VH and frequency of the audio signal input to the audio equipment and
To control light emission. However, the light emission control circuit of the present invention may detect an acoustic signal output once from an audio device and control the light emission of the LEDs 13 of the LED matrix 10 based on the detected signal.

Further, in the present invention, the design panel 30 that covers the front of the LEDs 13 arranged in a matrix is not essential, but if such a design panel 40 is provided, the dynamic visual effect of illumination by light emission and the design The display can be performed in combination with the static visual effect of the panel. As a result, the overall illumination effect can be doubled. Further, if the design panel 30 is made detachable as in the above-described embodiment, the design by the design panel 30 can be easily replaced with another design, and a display that does not get tired can be obtained.

Under the control of the light emission control circuit, the device normally operates in the shift display mode, and emits light in a mode corresponding to the volume and frequency of an audio signal output from an audio device such as a speaker. And
Since the number of LEDs corresponding to the sound volume emits light, the number of LEDs emitted or the total light amount changes in accordance with the volume of the sound output from the audio device. At the same time, since the LED emits light in a color corresponding to the frequency, the color of the LED changes according to the pitch of the sound output from the audio device. On the other hand, LED
Under the control of the light emission control circuit, the device operates in the pattern display mode at the timing when the volume and the frequency become predetermined values,

That is, it is possible to enjoy not only listening to the music but also enjoying the illumination (sound illumination) linked to the music. Further, the sound illumination can be displayed so as not to get tired of looking.

Further, in the shift display mode, the light emission state of the first column sequentially moves (shifts) to the next column without change. The light emitting state is maintained. That is, even if the light emitting state of the LED lasts only a short time in the same column, the light emitting state can be shifted in the row direction to display for a certain period of time, and the display time can be extended. can do. As a result, it is easy to respond to the display with eyes, and the visual effect by illumination can be enhanced.

When the volume and frequency reach predetermined values during the shift display mode, the light emission control circuit
Is switched to the pattern display mode. Then, to draw a predetermined planar geometric shape or pattern,
The LED at the position corresponding to the pattern emits light. Therefore, it is possible to change the display by the light emission of the LED at a predetermined timing. As a result, the visual effect of the illumination can be further enhanced.

According to a second aspect of the present invention, in the configuration of the first aspect, in the shift display mode, the LEDs arranged vertically in the same column in the shift display mode are proportional to the volume of the sound signal. Then, the LEDs in the lowermost position are sequentially illuminated in a bar graph form from the upper LEDs to the upper LEDs, and the lighting state is sequentially shifted to the right column,
The emission colors of the LEDs that light up in the same column are individually determined.

Accordingly, in the shift display mode, the number of LEDs proportional to the volume is lit by the control of the light emission control circuit, and the lit LEDs are arranged in the form of a bar graph from the lowest one to the upper one. Light. Further, the display state of the bar graph is sequentially shifted to the right column. As a result, the bar-shaped lighting LED shifts from left to right, so that the shifting display can be easily followed by eyes, and the visual effect by illumination can be improved.

Further, since the LEDs that are lit in the same row can be individually set to different lighting colors, illumination can be performed by various combinations of colors. As a result, the visual effect of the illumination can be further improved.

Are sequentially turned on in a predetermined order, and the planar geometrical shape is luminously displayed as a whole, and the luminous colors of the LEDs are individually determined.

Accordingly, since the pattern display is performed by the LEDs which are sequentially turned on, a unique illumination is obtained. In addition, since the LEDs to be lit can be individually set to different lighting colors, illumination can be performed by various kinds of color combinations. as a result,
The visual effect of the illumination can be further improved.
