Embodiment 1

[0026] A structure of a modular portable music percussion pad based on a single chip microcomputer:

[0027] Such as Figure 1-Figure 3 As shown, the music percussion pad includes a housing, a lower computer, an upper computer, a PCB circuit board, a driver integrated chip, an LED light, and a silicone conductive button (4); the lower computer and the upper computer are arranged in the housing, and the The PCB circuit board is arranged on the upper surface of the casing, the LED lamps are welded on the PCB circuit board and controlled by the driver integrated chip, and the silicone conductive buttons are arranged in a matrix and correspondingly cover the LED lamps.

[0028] The shell is formed by splicing and combining acrylic plates, specifically including an upper plate (1), a bottom plate (2) and 4 side plates (3) formed by overlapping two pieces of acrylic. It is a square box body, the inside of the box body is used to install the lower computer and the upper computer, an...

[0053] Functions of a modular portable music pad based on microcontroller:

[0054] In the specific implementation, plug the power input and output cables of DreamNano into the USB interface of Raspberry Pi 3B, use the Raspberry Pi power cable to supply power to the whole device, open the music editing software, and assign the keys of the device to key positions, and then The function of the music performance of the device is realized.

[0055] In practical application, DreamNano can be Arduino Leonardo (1) And other series of single-chip lower computer, Raspberry Pi 3B (2) Can be other minimal embedded systems. The above-mentioned upper and lower computers can be stacked together, and can also be placed in other places at the bottom of the casing, which saves space.

[0056] By tapping the silicone conductive button of this device, the circuit level on the PCB can be changed, and the circuit outputs the signal to the lower computer of the above device, and the lower comput...

Embodiment 3

[0060] The working principle of the circuit in a modular portable music percussion pad based on a single chip microcomputer:

[0061] (1) MIDI button circuit

[0062] 1. Button circuit

[0063] Such as Figure 4 As shown, the conduction of the circuit is controlled by the 1N4148 high-speed switching diode, and the trigger of the 4×4 matrix is ​​assigned to 16 different channels. When the silicone conductive button is pressed, the circuit on the circuit board is triggered to conduct, and the circuit level changes. The output is binary characters, which are transmitted to the single-chip microcomputer through an asynchronous channel. The single-chip microcomputer converts the binary characters into MIDI Message, transmits it to the host computer, triggers the software reading of the host computer, and transmits the specific sound command to the audio system to make a sound.

[0064] 2. Matrix keyboard parallel circuit

[0065] The circuit distinguishes different 4×4 matrices ...

Abstract

The invention discloses a modularized portable music percussion pad based on single chip microcomputer, comprising a shell, a lower computer, an upper computer, a PCB circuit board, a driving integrated chip, an LED lamp and a silica gel conductive key; the upper computer and the lower computer are arranged in the shell, the PCB circuit board is arranged on the upper surface of the shell, the LEDlamp is welded on the PCB circuit board and controlled by the driving integrated chip, an the silica gel conductive key correspondingly covers on the LED lamp in matrix arrangement. The device reducesthe manufacture cost of existing commercialized music percussion pads, and ensures the music production quality under the condition of reducing the cost, and can be used by a modularized integrated small-dimension processor without being connected to a large PC terminal computer, so that the music can be produced anywhere anytime, the use is convenient, and the portability is increased.

Description

technical field [0001] The invention relates to a percussion instrument, in particular to a modular portable music percussion pad based on a single-chip microcomputer. Background technique [0002] At present, with the rapid development of science and technology, music production technology is also advancing by leaps and bounds, MIDI controllers are becoming more and more popular, and countless music producers use them. A MIDI controller is a device that performs information interaction through the MIDI protocol. The most popular MIDI controller on the market is a product produced by Novation. In principle, the controller does not produce any sound source and sound-generating device. It is a musical instrument keyboard used to control other professional music editing software. It can be understood as the relationship between the keyboard and the mouse to the computer. Can be used to control music workstations, the more popular one is Ableton Live. The playing principle is ...
