Abstract
The utility model discloses a multi-color music display. A single-chip microcomputer is provided with a filter circuit, a high-mid-low sound frequency divider, an LED driving program, wherein the filter circuit is connected with an ADC audio signal collecting module, and the LED driving program is respectively connected with a red LED lamp, a green LED lamp and a blue LED lamp. The multi-color music display employs a highly integrated STC single-chip microcomputer and an ADC audio signal collecting module for acquiring audio signals, and generates glamorous multicolor effects through cooperation between three groups of high-mid-low sound audio display and glaring blue, green and red LEDs. Light-up parts of the LEDs and light intensity of each LED vary with music rhythms. The combination of lighting location, intensity variation and various music forms generates numerous display effects, thereby bringing audio-video entertainment for a user rather than just audio enjoyment of music.
Description
Technical field
The utility model belongs to the display device technical field, relates to a kind of illusion-colour music display.
Background technology
Common music player only possesses simple playing function, does not have the function of colourful illusion-colour light with the music flicker, uses the comparison dullness.
Summary of the invention
The purpose of this utility model provides a kind of illusion-colour music display, can be with the music flicker color lamp of playing.
The technical solution adopted in the utility model is, a kind of illusion-colour music display, on single-chip microcomputer, be respectively arranged with filtering circuit, high, normal, basic sound frequency divider, LED driver, filtering circuit also is connected with ADC audio signal sample module, and single-chip microcomputer also is connected with red LED lamp, green LED lamp and blue led lamp respectively.
Feature of the present utility model also is,
Single-chip microcomputer adopts the STC12C4052AD single-chip microcomputer.
Illusion-colour music display of the present utility model, utilize the STC series monolithic of high integration, by ADC audio signal sample module audio frequency acquiring signal, utilize high, normal, basic sound frequency divider to distinguish signal frequency then, have basic, normal, high three groups of audio frequency and show, cooperate the ultra-bright LED of blue, green, red these three kinds of colors to reach to dazzle colour display screen and show effect.LED not only can beat with the music dipping and heaving, and the brightness power of each LED also can be glimmered with music.So rise and fall and the combination of glimmering, music itself is rich and varied in addition, makes display effect make a lot of variety.The music that originally can only listen but can bring you now and dazzle cruel seeing and hearing enjoyment.
Description of drawings
Fig. 1 is the circuit theory diagrams of the utility model illusion-colour music display.
Among the figure, 1. single-chip microcomputer, 2.ADC audio signal sample module, 3. filtering circuit, 4. high, normal, basic sound frequency divider, 5.LED driver, 6. red LED lamp, 7. green LED lamp, 8. blue led lamp.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
The circuit structure of the utility model illusion-colour music display, as shown in Figure 1, on single-chip microcomputer 1, be respectively arranged with filtering circuit 3, high, normal, basic sound frequency divider 4, LED driver 5, filtering circuit 3 also is connected with ADC audio signal sample module 2, and single-chip microcomputer 1 also is connected with red LED lamp 6, green LED lamp 7 and blue led lamp 8 respectively.
The single-chip microcomputer 1 of the utility model illusion-colour music display adopts the STC12C4052AD series monolithic, ADC audio signal sample module 2 is the rings of first in the illusion-colour music display function chain, one 8 ADC function that the STC12C4052AD series monolithic is inner integrated, under the situation of 24MHz external clock, the slewing rate of ADC can reach per second 90,000 times.Enough for general audio collection and processing.Well-known sound signal is a simulating signal, handles through ADC to become from 0 to 255 this interval numerical value.These numerical value change along with music content rises and falls, and the numerical value of these changes is coupled together in chronological order just formed audio curve.LED lights what, by the decision of the numerical value after the ADC conversion.The realization of frequency division is to detect in real time in the audio frequency of input with program in the high, normal, basic sound frequency divider 4, analyzes audio volume control in a certain period, measures the distance between two same waveform as, and this distance is the frequency of this waveform just.Red LED lamp 6, green LED lamp 7 and blue led lamp 8 adopt the type of drive of lattice arrays, come the quantity and the brightness of driving LED according to the sampling of the ADC between a certain audio zone numerical value.
Illusion-colour music display of the present utility model utilizes the STC series monolithic of high integration, adds that few peripheral circuit and the Audio Signal Processing of all being finished by software realize the control of color lamp.Have basic, normal, high three groups of audio frequency and show, cooperate the ultra-bright LED of blue, green, red these three kinds of colors to reach to dazzle colour display screen and show effect.LED not only can beat with the music dipping and heaving, and the brightness power of each LED also can be glimmered with music.So rise and fall and the combination of glimmering, music itself is rich and varied in addition, makes display effect make a lot of variety.The music that originally can only listen but can bring you now and dazzle cruel seeing and hearing enjoyment.
