Detailed Description

The present invention will be described in detail below with reference to the drawings in conjunction with examples, but the embodiments of the present invention are not limited thereto.

Example (b): in the example of fig. 1, the color music system includes:

the device comprises a microprocessor unit 1, a key unit 2, an LCD display unit 3, a light display unit 4, an interface unit 5, a storage unit 6, an audio decoding unit 7, an audio signal processing unit 8 and a playing unit 9;

the microprocessor unit 1 is connected with the key unit 2, the LCD display unit 3 and the light display unit 4; the microprocessor unit 1 is coupled to the input terminals of the storage unit 6 and the audio decoding unit 7 through the interface unit 5; the output end of the audio decoding unit 7 is coupled to the input end of the audio signal processing unit 8; the output end of the audio signal processing unit 8 is coupled to the microprocessor unit 1; the audio decoding unit 7 is coupled to the playing unit 9.

As shown in fig. 1, the microprocessor unit 1 is coupled to the storage unit 6 through the interface unit 5, and can read music files from the storage unit 6. The microprocessor unit 1 adopts an STC15W4K61S4 chip, the storage unit 6 can be an SD card or a usb disk, and the microprocessor unit 1 is coupled to the input end of the audio decoding unit 7 through the interface unit 5, so that the microprocessor unit 1 can send the audio file read from the storage unit 6 to the audio decoding unit 7, and then the audio decoding unit 7 can decode the read audio file, wherein the audio decoding unit 7 can be a VS1005 type audio codec, and the VS1005 type audio codec is a single MP3/AAC/WMA/MIDI audio decoder, and can also implement adaptive differential pulse code modulation, and can implement the functions required by the present invention;

as shown in fig. 1, the output terminal of the audio decoding unit 7 is coupled to the input terminal of the audio signal processing unit 8, and the output terminal of the audio signal processing unit 8 is coupled to the microprocessor unit 1, so that the audio signal processing unit 8 can amplify the audio signal obtained by decoding the music file and then send the amplified audio signal to the microprocessor unit 1. The microprocessor unit 1 receives the amplified audio signal (analog signal), AD-converts it, and then performs chord extraction on the music file using some music composition software. Then, we perform spectrum analysis on each chord of the music, for example, we may perform spectrum analysis on the chord by using matlab software, then compare the result of the spectrum analysis with the result of the spectrum analysis on the standard chord, determine the standard chord closest to the chord, then determine the display scheme corresponding to the standard chord as the display scheme of the chord, and display the display scheme through the light display unit 4 coupled to the microprocessor unit 1;

by extracting chords from the amplified audio signal (analog signal), the light display unit 4 can synchronously display the corresponding light display scheme according to the time of each chord in the chord sequence, wherein the light display unit 4 can be a 16 x 16 tower-shaped lattice;

the design inspiration of the 16-X16 tower-shaped lattice comes from the common lattice in daily life, and is different from the lattice seen in daily life in that the rectangular lattices seen in daily life are connected into a cylinder, and small lamps in the middle of the cylinder are welded to be slightly tight, so that the tower-shaped lattice is beautiful. The tower-shaped lattice has 16 layers in total, 16 small lamps are welded on each layer, and 256 small lamps form 16X 16 lattices in total, and all the 256 small lamps use seven-color-changing LEDs. The biggest difference between the seven-color-changing LED and the common light emitting diode is that it can display different colors by adjusting the duty ratio according to the PWM technique. The seven-color-changing LED is particularly suitable for the patent, because the seven-color-changing LED can display seven colors including red, orange, yellow, green, cyan, blue and purple. Before programming the seven-color-changing LED, the color of the seven-color-changing LED needs to be tested, different PWM values are output respectively, the color of the seven-color-changing LED under the PWM values is recorded, and therefore the programming of the whole system is ready in the future;

in addition, it should be further noted that the audio signal processing unit 8 includes audio signal collecting and amplifying branches, wherein an audio input end of the audio signal collecting and amplifying branch is coupled to an output end of the audio decoding unit 7, and an output end of each audio signal collecting and amplifying branch is coupled to the microprocessor unit 1;

in addition, the audio decoding unit 7 decodes the music file in the storage unit 6 to obtain an audio signal of the music file, the rhythm and the intensity of the music are converted into control signals through the microprocessor unit, and the on-off and the colors of 256 colorful color-changing LEDs in the light display unit are controlled according to the control signals, so that the 16-16 tower-shaped dot matrix can display different colors and animations based on the change of the music;

as can be seen from the above description, according to the present invention, the chord extraction is performed on the decoded and amplified audio, and the frequency spectrum analysis is performed on the extracted chord, so as to compare the frequency spectrum of each chord of the played audio with the frequency spectrum of the standard chord, and determine the light display scheme of the standard chord closest to the frequency spectrum of each chord of the played audio as the light display scheme of the corresponding chord. That is to say, as the music chord changes, the corresponding light display scheme also changes continuously, thereby realizing the technical requirement that the color and the animation of the light change along with the change of the music chord also change;

fig. 2 is a circuit diagram illustrating an example of an application of the light music psychophysical therapy system shown in fig. 1. As shown in fig. 2, in this application example, an STC15W4K61S4 type microprocessor (as an example of a microprocessor unit 1) is coupled to an SD card or a usb disk memory (as an example of a storage unit 6) through an SPI bus, and is coupled to a VS1005 type audio decoder (as an example of an audio decoding unit 7) through an SPI bus, and the VS1005 type audio decoder includes two output channels, i.e., "left speaker" and "right speaker" shown in fig. 2. Through the two sound boxes in fig. 2, music playing can be realized;

the LCD12864 shown in fig. 2 displays liquid crystal to display lyrics of music files in the SD card. The LCD12864 adopts +5V power supply, a proper pin of the STC15W4K61S4 is used as an RS control signal of the LCD12864 to determine whether the singlechip selects data or instructions, and when RS is 1, data operation is performed; a write command or a read state operation when RS is 0; a proper pin of the STC15W4K61S4 is used as an R/W selection signal to determine whether the single chip microcomputer performs read gating or write gating on the display module; an appropriate pin of STC15W4K61S4 is asserted to determine whether the data is latched or read; 8 interfaces of STC15W4K61S4 are connected with DB 0-DB 7 of LCD12864 liquid crystal for data transmission between the two interfaces;

the key unit is used for controlling a music file to be played, one end of the key unit is connected with GND, and the other end of the key unit is connected with a pin of STC15W4K61S4 (a pull-up resistor is required to be arranged in the pin), and then the microprocessor unit judges whether the key is pressed down according to whether the pin has level change or not so as to judge whether the played file is switched or not.
