基于特莱明的电子乐器

Based on theremin's keyboardAbstractTerai MingQin (Theremin)is a kind of based on tube early and simple analog circuitof the electronic instrument,is made up of the former Soviet union radio engineers,Ming (Leon Theremin),invented in the 1920 s.The principle is in after turning on thepower supply,internal tube wave oscillator and many of the components,artificially tointerference waves to form the different volume.The theremin is the earliest electronicinstrument in recorded history.Based on this instrument,various popular electronicmusic genres gradually developed and became an indispensable branch of the musicindustry.It opened a window for the development of later electronic keyboardinstruments,and also opened the prelude of electronic instruments.However,due to thedifficulty in mastering its performance skills,theremin requires high musicalaccomplishment of players.However,it is about to be eliminated due to the lack of thecompatibility of keyboard instruments and the diversity of timbre.This project designaims to restore the basic structure of the tremens,achieve the basic performancefunction and improve the operability of the instrument by visualizing the sound level ofthe original "blind tasting"tremens output,which greatly reduces the difficulty oflearning and playing the instrument.In addition,the musical instrument's sound sourcelibrary is greatly enriched,so that it can meet the growing demand of the music industryfor the diversity of arrangement.Keywords:Theremin;vacuum tube;analog circuit;visualization
