Abstract

A playing assistance device used for playing a musical instrument is disclosed. A direct current rheostat is arranged in a plastic pipe with small two end ports and a large intermediate portion. An air flow is blown in the pipe from a front end of the plastic pipe. A spring is arranged behind a slide plate. A sliding variable resistor controls rotation of a motor and a wind instrument. Various kinds of musical instruments can be played simultaneously at a time, such as a flute, a bamboo flute, a trumpet, a medium horn and the like. The motor drives a blower and a fan blade to rotate so as to generate wind power. The wind power can be used to play the musical instrument which is played through a mouth originally. The strength of the current controls a sound level. A magnetic force of an electric coil is used to imitate fingers of human beings to press sound holes or keys on the wind instrument so as to play various kinds of notes and different melodies.

Description

Blowing instrument helps and blows device

Affiliated technical field

The utility model relates to a kind of electric power that relies on and helps people to carry out the auxiliary blowing apparatus of blowing instrument, once plays wind instruments multiple musical instrument simultaneously, like flute, bamboo vertical bamboo flute, trumpet, medium size or the like, is that a kind of novel helping that replaces manpower to play wind instruments by machinery blown apparatus.

Background technology

At present, a known general people plays wind instruments a musical instrument, and some blowing instrument blows afloat also gruelling.

Summary of the invention

Blow afloat relatively painstakingly in order to overcome some blowing instrument, like flute, trumpet or the like, a people only can play wind instruments a musical instrument; The utility model is provided with a kind of apparatus, utilizes the rotation of motor drives fan blade, guides wind-force into shape, position that blowing instrument blows hole (inflatable mouth) simulation population by pipeline again; Up to blowing musical instrument, the power of current switch Control current then, blowing instrument sound height size; Simultaneously; Utilize the action of the magnetic force imitation finger of hot-wire coil, push the sound hole or the key of blowing instrument, play out the music of various different melody.

The technical scheme that the utility model technical solution problem is adopted is: young at two ends; Rheostat is flowed in setting always in the plastic conduit broad in the middle; Air-flow is blown into from the plastic conduit front end, is provided with spring behind the slide plate, and device is played wind instruments in the rotation of described slide rheostat control motor.

The utility model is created the beneficial effect that brings: 1, a people can play wind instruments a plurality of musical instruments.2, save muscle power.

Embodiment:

In Fig. 1 and Fig. 2, in the big plastic conduit 1 of the young intermediate space in two ends, slide rheostat 2 is set, when population when front end is inwardly blown; Slide plate 3 moves right, and electric current becomes greatly gradually, otherwise; Under the reaction force acts of spring 4, electric current diminishes, only to outage.What slide rheostat 2 was controlled is the electric current variation of hair-dryer 6.

When electric current broke off, stop operating piston 7 of hair-dryer stopped up gassing pipes, and airbag 11 expands and collects residual gases.When pressing bond switching 5 closures, the iron stamen receives to press down under the magneticaction sound hole 10 in the hot-wire coil 9.Play out the various different note sounds.

One, plays wind instruments, power is provided, drive the fan blade rotation by motor; Form air-flow and played wind instruments by the hole (inflatable mouth) of blowing of pipeline flow-direction blowing instrument, provide the apparatus in wind-force source to be called hair-dryer to blowing instrument here, critical piece has: power supply, hair-dryer, gas blow pipe, conduit, direct current slide rheostat or AC speed regulating switch, spring, piston, airbag or the like; With direct current slide rheostat or AC speed regulating switch, it is young to be placed in two ends, in the big plastic conduit of intermediate space; There are 6 or 7 pressure bond switchinges the outer top of pipeline, controls each hot-wire coil (there is detailed description the back), and gas blows into from osculum one end in the population; Blow slide plate on the slide rheostat, spring arranged behind the slide plate, when stopping to blow on the slide rheostat electric current be zero; Be in off-position, the big more electric current of blowing is big more, and the AC speed regulating switch also is same; Hair-dryer is communicated with by plastic conduit with blowing instrument, and a bifurcated pipe is set on pipeline, leads to airbag; A piston is arranged leading on the blowing instrument pipeline, when stopping to settle the plastic conduit of slide rheostat to blow to the centre, circuit breaks off; Do not have electric current, piston has hot-wire coil, iron stamen, spring rapidly with the line clogging of air communication to blowing instrument behind piston.Magnetic force is not zero when having electric current through coil, and spring ejects the iron stamen, and piston advances forward is stopped up tracheae; Because hair-dryer when off-position, under inertia effect, is still rotating; When closing of circuit, piston is opened, and hair-dryer rotates; Gas backstreaming in the elastic caoutchouc airbag, the wind-force small voice is little when so just solving starting just, the shortcoming of delay of response.Two, push blowing instrument sound hole (key); We know that China's popular musical instrument flute, bamboo vertical bamboo flute etc. all are sound holes; The trumpet in external west, medium size, saxophone etc. are keys; The people once only can push a musical instrument; Machinery then difference once can be pushed a plurality of musical instruments, and the pushing of all musical instrument sound holes or key all leaned on the elastic force of magnetic force that hot-wire coil produces and spring to interact and realized that critical piece is set to be had: press bond switching or do not have money and press bond switching, coil, iron stamen, spring, lead, elastic rubber plug, plastic layer, plastic clip or the like formation.Here be example with the bamboo vertical bamboo flute, plastic clip is at first fixed bamboo vertical bamboo flute two ends bamboo vertical bamboo flute, and a coil, iron stamen, spring, plastic layer, elastic rubber plug are all arranged on each sound hole of bamboo vertical bamboo flute, and coil magnetic force is downward during energising; In the plastic layer lower end elastic rubber plug is arranged, receive magneticaction to stop up sound hole on the bamboo vertical bamboo flute, it can not be spoken; And not blocked sound hole blows out the sound under the air-flow effect of hair-dryer, during outage; Lose magnetic force, under the retroaction of the elastic force of spring, plastic layer ejects; Elastic rubber plug leaves the sound hole position, according to the needs of music score, pushes each arbitrarily and presses bond switching.For example: when hand is pressed the note of bond switching " 3 ", so, no matter be flute, the bamboo vertical bamboo flute has all sent the sound of " 3 ", once can control a plurality of musical instruments.To blow the note effect of sending in the hole the same with blowing instrument itself.Blow the slide plate on the slide rheostat (speed-regulating switch), Control current intensity as this with population; The hand pushing power switch, control coil magnetic field, thereby realize the assistive device that blowing instrument is played; Suppose to be provided with wiretap, can only control a blowing instrument less so, circuit is very complicated; If for control to more a plurality of blowing instruments, have only the radio remote control switch of using so, there are two kinds of methods to implement; 1, ultrasonic emitting, 2, radio coding and decoding mode.

Claims

1. a blowing instrument helps and blows device, it is characterized in that: young at two ends, rheostat is flowed in setting always in the plastic conduit broad in the middle, and air-flow is blown into from the plastic conduit front end, is provided with spring behind the slide plate, and device is played wind instruments in the rotation of described slide rheostat control motor.
