Referring to fig. 1-3, the present embodiment provides a hand-worn electronic musical instrument 100 based on wireless communication, including a housing, a distance sensor 120, a microcontroller 110 and a first communication module 130;

the distance sensor 120, the microcontroller 110 and the first communication module 130 are arranged in the shell;

the distance sensor 120 is electrically connected to the microcontroller 110, and the distance sensor 120 is used for detecting the distance between the electronic musical instrument and the reference plane;

the first communication module 130 is electrically connected to the microcontroller 110, and the first communication module 130 is configured to send a MIDI message generated by the microcontroller 110.

The microcontroller 110 is a single-chip microcomputer in which the main part of the microcomputer is integrated on one chip. The Microcontroller 110(Microcontroller Unit, MCU) can be classified in different ways: the data bus can be divided into 8 bits, 16 bits and 32 bits according to the width of the data bus; the structure can be divided into a Harvard structure and a Von Neumann structure according to the memory structure; according to the category of the embedded program memory, the embedded program memory can be divided into OTP, mask, EPROM/EEPROM and Flash; according to the Instruction structure, the microcontroller 110 may be further divided into a CISC (Complex Instruction Set computer) and a RISC (reduced Instruction Set computer).

MIDI (Musical Instrument Digital Interface) is the most widely used music standard format in the composer world and may be referred to as "computer-understandable score". It records music with digital control signals of the notes. A complete MIDI music is only a few tens of KB large and can contain dozens of music tracks. Almost all modern music is synthesized using MIDI plus a library of tones. Rather than a sound signal, the MIDI transmits instructions, such as notes, control parameters, which instruct the MIDI device what to do, such as which note to play, how much volume, etc. They are collectively represented as MIDI messages (MIDI messages).

The hand-worn electronic musical instrument 100 is worn on the hand of the user through a wearing structure on the housing, when the user plays through the hand-worn electronic musical instrument, the distance between the distance sensor 120 and the reference plane is controlled by facing the distance sensor 120 to the reference plane, the microcontroller 110 obtains a note corresponding to the distance information according to the distance information fed back by the distance sensor 120, then generates a MIDI message in a standard format, and sends the MIDI message to a corresponding terminal through the first communication module 130 for playing.

The microwave ranging sensor measures distance by utilizing electromagnetic waves with the wavelength of 0.8-10 cm as carriers, the microwave ranging sensor sends out microwave signals directionally by a microwave emitter, and when the microwave signals meet an object to be measured, the microwave signals are partially absorbed by the object to be measured and partially reflected. The receiving antenna is used for receiving the microwave signal reflected by the measured object, detecting the electromagnetic parameter of the microwave signal, and processing the microwave signal by the measuring circuit, so that the microwave detection is realized. The microwave distance measurement has the advantages of high measurement precision, high reaction speed, good directionality and non-contact

Referring to fig. 3, in order to make the musical note played by the hand-worn electronic musical instrument more accurate, when the hand-worn electronic musical instrument is started, the microcontroller 110 calibrates the height corresponding to the C key, wherein the microcontroller 110 sends calibration information to an external device through the first communication module 130, for example, the mobile phone or MIDI sound source product sends the calibration information, and when the user receives the calibration information, the microcontroller calibrates the current distance information to the C key by placing the hand-worn electronic musical instrument at a reasonable position from the reference plane.

In the second performance mode shown in fig. 5, after the rhythm speed is set by the touch sensor 151, for example, the tempo of 16 minutes of notes is set, when the electronic musical instrument is played by hand, the microcontroller 110 reads the data of the distance sensor 120 at each tempo point of 16 minutes of notes and generates a corresponding note playing. Under the mode, a player can realize continuous playing only by lifting the hand to the position corresponding to the musical note on the staff sticker according to the rhythm on the basis of controlling the speed, and the specific flow is as follows:

firstly, the hand is placed at the central C-tone position of the staff sticker to calibrate the height, after the calibration is completed, the microcontroller 110 performs timing according to the set rhythm speed, for example, 16 minutes of note timing, when the microcontroller 110 finishes the 16 minutes of note timing every time, the height information is detected through the distance sensor 120, the note corresponding to the current height information is calculated according to the height model, then the MIDI message corresponding to the note is generated and played, and the MIDI message is sent to the corresponding playing device through the first communication module 130 to be played.
