FIG. 1 is a diagram schematically illustrating the configuration of an equalizer display apparatus according to an embodiment of the present invention. Referring to FIG.

1, an equalizer display 100 according to an exemplary embodiment of the present invention includes an acoustic signal input unit 110, a signal amplification unit 120, a filter 130, a converter 140, and a light emission control unit 150. [ . ≪ / RTI >

The sound signal input unit 110 receives the sound signal. At this time, the sound signal input unit 110 may receive an external sound signal through a microphone, or may be connected to an audio output unit (not shown) such as an MP3 player or audio equipment to receive the sound signal.

The signal amplifying unit 120 amplifies the sound signal received through the sound signal input unit 110 at a predetermined ratio.

The filter 130 filters the acoustic signal input through the acoustic signal input unit 110 or the acoustic signal amplified by the signal amplification unit 120. At this time, the filter 130 may be implemented as a band pass filter as shown in FIG. In this case, the filter 130 classifies the frequency band into a plurality of steps, determines the frequency of the acoustic signal inputted through the acoustic signal input unit 110 or the acoustic signal amplified by the signal amplifying unit 120, It is possible to determine which phase of the divided frequency corresponds to which frequency band of the determined phase.

The converter 140 converts the signal filtered by the filter 130 into an analog / digital signal. In other words, the converter 140 determines which stage of the classified acoustic signal the acoustic signal filtered by the filter 130 corresponds to, and outputs a digital signal corresponding thereto. For example, when the filter 130 classifies the acoustic signals into eight levels according to the frequency band and filters the signals as shown in FIG. 3, the converter 140 outputs digital signals corresponding to the respective frequency bands .

The light emission control unit 150 controls the light emission of the LED cube made of N x N x N (N is an integer) LEDs according to the digital signal converted by the converter 140.

Fig. 4 is a diagram showing an example of the circuit configuration of an LED cube composed of 3 x 3 x 3 LEDs as an example of a circuit configuration of an LED cube. As shown in Fig. 4, each of the LEDs can be individually controlled by controlling the current supplied to each LED constituted by 3 x 3 x 3.

In the embodiment of the present invention, it is assumed that the LED cube is composed of 8 x 8 x 8 LEDs as shown in Fig. 3, the light emission control unit 150 may perform emission control corresponding to each stage of the LED cube, as shown in FIG. 6, in accordance with digital signals output in eight stages.

For example, the light emission control unit 150 defines one zone for the LED cubes as eight columns, and one column corresponds to each digital signal outputted by the converter 140 . At this time, the light emission control unit 150 divides the LED light emitting area of the LED cube into eight zones. If the zone displayed at the current time t is different from the zone displayed after the unit time? T from the current time t, The value can be displayed by decrementing one by one. In the same manner, the light emission control section 150 can display any one zone at t + 2? T and display it at a time t and decrease the value of the zone displayed at time t + t by one. When displayed in this manner, the information displayed on the LED cube at time t has the highest probability of displaying information up to time t and t - 7? T.

7 is a view showing another example of light emission control for the 8 x 8 x 8 LED cubes of Fig.

7, the light emission control unit 150 displays a channel for each frequency band in the x-axis direction with respect to the LED cube, displays the size in the z-axis direction, and displays the time in the y-axis direction. In this case, at time t 8 channel information can be displayed in one x-z plane, so that the LED cube can simultaneously display eight specific time information. In addition, the light emission control unit 150 displays channel information in the xz plane at y = 0 at the current time t in eight steps, moves information of y = 0 to y = 1 after unit time? T, + Δt time information. When the LED is controlled to emit light in this manner, the cube displays information from time t to t-7? T. In this case, there are 64 columns in the cube, and the height of the column represents the size (z axis) of a specific frequency band (x axis) at a specific time (y axis).

8 is a flowchart illustrating an equalizer display method according to an embodiment of the present invention.

1 to 8, the sound signal input unit 110 receives the sound signal (S110). At this time, the sound signal input unit 110 may receive an external sound signal through a microphone, or may be connected to an audio output unit (not shown) such as an MP3 player or audio equipment to receive the sound signal.

The signal amplification unit 120 amplifies the sound signal received through the sound signal input unit 110 at a predetermined ratio (S120).

The filter 130 filters the sound signal input through the sound signal input unit 110 or the sound signal amplified by the signal amplification unit 120 (S130).

The converter 140 analog-to-digital converts the signal filtered by the filter 130 (S140). In other words, the converter 140 determines which stage of the classified acoustic signal the acoustic signal filtered by the filter 130 corresponds to, and outputs a digital signal corresponding thereto.

The light emission control unit 150 controls the light emission of the LED cube composed of N x N x N (N is an integer) light emitting diodes according to the digital signal converted by the converter 140 (S 150) .
