Non-contact type intelligent electronic musical instrument for serving special populations

Abstract

The invention belongs to the field of intelligent electronic musical instruments, and more particularly relates to a non-contact type intelligent electronic musical instrument for serving special populations (such as people with fingers incapable of flexibly moving, finger muscle weakness, incomplete fingers and the like due to innate or acquired factors). The novel electronic musical instrument comprises an MCU main controller 11, and a music playback control button 21, a foot-pedal tone rising button 31, a foot-pedal tone falling button 32, ultrasonic sensors 41, a music interface effect button 61, a music playback control indicating lamp 71, a tone falling indicating lamp 72, a tone rising indicating lamp 73, a power indicating lamp 74 and an upper machine animation effect device 81 which are connected with the MCU main controller 11, wherein the upper machine animation effect device 81 is connected with a loudspeaker 51. When in use, a user is in contact with seven sensors in a non-touch manner, corresponding signals are acquired and processed by software to ''perform'' wonderful music, and real-time animation effect can be displayed on an upper machine, thereby achieving human-computer interaction. The non-contact type intelligent electronic musical instrument has the advantages of being non-contact type, easy to operate, modular and intelligent, and is mainly suitable for special populations to use.

Description

technical field [0001] The invention belongs to the field of intelligent electronic musical instruments, and in particular relates to a non-contact intelligent electronic musical instrument serving special groups of people. Background technique [0002] According to the National Sample Survey on Disabled Persons, the proportion of disabled population in my country is increasing year by year. In daily life, most disabled people are limited by their own reasons in the process of realizing their wishes, so many people are under great psychological pressure. Their lives are monotonous and lack fun, but music can help relieve stress and cultivate sentiment. In today's society, there are many people who have dreams of music, but because of congenital or acquired factors, they have physical disabilities and inflexible fingers, so that they pay more hardships than ordinary people in the pursuit of music. Based on this kind of phenomenon, in order to enrich the spiritual life of th...

Problems solved by technology

[0004] In order to achieve the above object, the technical solution of the present invention to solve the non-contact playing technology and practical problems is to store different pitch frequencies in the software in advance using mathematical thinking, and detect that there is a signal input by the ultrasonic sensor 41 detection technology. , the scale acquisition and transmission module 4 transmits the collected signal to the MCU main controller 11, and the MCU main controller module 1 transmits the signal analysis and processing to the upper computer software system, and the upper computer software system plays by calling the audio library function The pre-stored different pitch frequencies are played in the man-machine interface module 8, which solves the technical problems of non-contact and easy playing for disabled people such as inflexible fingers, incomplete fingers or insufficient finger force.
