Problems solved by technology

The disadvantage of the former is that one key corresponds to one color of light, and the change of light color is monotonous; the disadvantage of the latter is that the change of light color can only follow the established program, or although it can produce the effect of random change, the change of light color is not the same as that of piano playing. The music is disconnected, does not match, and the artistic appeal is not good enough

Embodiment 1

[0011] According to the circuit principle of a light-emitting piano with rich light and color changes according to the present invention, it is as follows: figure 1 As shown, it includes a pickup 1 installed on a piano, a programmable controller 2 and a color-changing LED light-emitting element 3 . The pickup 1 is connected with the analog-to-digital conversion input terminal A / D of the programmable controller 2 . An amplifier circuit and a shaping circuit can be added between the pickup 1 and the programmable controller 2 . Programmable controller 2 is a single-chip microcomputer. The color-changing LED light-emitting element 3 can be either a color-changing LED chip or a color-changing LED light-emitting tube. This color-changing LED light-emitting element integrates LED chips of three colors of red R, green G, and blue B in one element, and the chips of the three colors lead to a control pin respectively. The three control pins of a single color-changing LED light-emitti...

Embodiment 2

[0014] see figure 2 In this embodiment, on the basis of the first embodiment, a plurality of color-changing LED light-emitting elements 3a-c are connected in series to enhance the brightness and facilitate simultaneous illumination of multiple keys.

Embodiment 3

[0016] see image 3 , this embodiment adopts the structure of multiple outputs on the basis of the first embodiment. The three pulse signal output pins PWM1~PWM3 of the programmable controller 2 control one of them, and the other three pulse signal output pins PWM4~PWM6 control the other, and so on. The color-changing LED light-emitting element can emit light of different colors independently. Each key corresponds to one color-changing LED light-emitting element, so that each key can emit light of different colors, and the light emitted by each key can change with the light color change of the color-changing LED light-emitting element.

[0017] Each color-changing LED light-emitting element can also be as figure 2 In that way, multiple color-changing LED light-emitting elements are connected in series.

Abstract

The invention discloses a lighting piano with rich light-color changes. The piano is provided with a sound pickup, a programmable controller and a color changing LED (light-emitting diode) luminous element, wherein the sound pickup is connected with an analog-to-digital conversion input end of the programmable controller; each control pin of the single color changing LED luminous element is respectively connected with a pulse signal output pin of the programmable controller; an internal program of the programmable controller controls the color changing LED luminous element to emit light with different colors according to frequency of audio signals transmitted by the sound pickup, so as to enable the light-color generated by the piano to change along the playing pitch change. According to the invention, the light-color change is extremely rich and matched with the music change closely, so that the artistic appeal is very strong.

Description

technical field [0001] The invention relates to a piano, in particular to a piano with light effects. Background technique [0002] Currently known pianos with lighting effects either control the LEDs to emit light through switches linked with the keys, or control the LEDs to emit light according to predetermined program changes. The shortcoming of the former is that one key corresponds to one color of light, and the light color changes monotonously; The music is unconnected, mismatched, and artistically underwhelming. Contents of the invention [0003] The object of the present invention is to provide a light-emitting piano with rich light and color changes, so as to enhance the artistic appeal of the piano. [0004] The present invention is realized in this way: a light-emitting piano with rich light and color changes, a pickup, a programmable controller, and a color-changing LED light-emitting element are installed on the piano, the pickup is connected to the analog-t...
