Abstract

The utility model discloses an electronic mouth-organ with the same play method with traditional mouth-organ and with the electronic organ sound effects, comprising a casing, an acoustic horn, exhaling/inhaling holes, pneumoelectric sense switches and integrated acoustic circuits. The connected pneumoelectric sense switches are closed in sequence, the integrated acoustic circuits are conducted one by the musical scale switch to perform graceful music when players exhale/inhale with the mouth-organ in mouth, the electronic mouth-organ can play all kinds of musics when start up tempo keys and the tone keys.

Description

Electronic mouth-organ

The utility model discloses a kind of, identical with traditional mouth organ playing method, have the hand acoustic electronic organ that plays the electronic piano.

The tradition mouth organ is the elastic spring by inside, be subjected to the impact shock of air-flow and send sound equipment, though there is volume little, characteristics such as easy to carry,, it is narrower that this musical instrument exists range, tonequality is relatively poor, can not modify tone, and does not have shortcomings such as the beat accompaniment is arranged, so far can not adapt to the needs of contemporary music development, the trend that is eliminated is arranged greatly.

In order to carry forward traditional culture, inject new vitality for existing mouth organ, the invention provides a kind ofly, use traditional mouth organ playing method to play, have the play the electronic piano novel musical instrument of effect of hand.

The utility model is made up of shell, pressure-vaccum pore, pronunciation loudspeaker, beat key, modified tone key, note sign, pilot lamp, power switch, pneumoelectric sensitive switch and electronic audio circuit.Player during use, suck qin, facing to blow, suction hole is blown regularly, air-breathing, this moment the air bag that communicates with it expand along with splashing or dwindle be directed at it near resilient contact switch break-make regularly, thereby the control acoustics circuit is played out different scales, forms graceful melody.Start beat key and modified tone key, can play various dissimilar melodies.The complete machine range is extensive, and the tonequality grace is small and exquisite, is easy to carry, and is adapted to travel, the performance of rally and various entertainment places.

The present invention is further detailed explanation below in conjunction with accompanying drawing:

Accompanying drawing 1 is circuit theory diagrams of the present invention.

Accompanying drawing 2 is pneumoelectric sensitive switch structural representations of the present invention.

Accompanying drawing 3 is outside drawings of the present invention.

With reference to accompanying drawing 3, electronic organ is by shell (1), is installed in the pilot lamp (8) on the shell, loudspeaker (9), and tone key (5), beat key (6), power switch (7), note sign (4) are formed.In the position, front lower place of shell (1), a row's gas hole (2) and a suction hole (3) is set.(blow, suction hole is spaced, wherein scale 1,3,5 is a blowing sound, the 2,4,6, the 7th, sound-absorbing.）

With reference to accompanying drawing 2, K ₁Be the air blowing sensitive switch, by introversion type elastic sheet metal (10), (12), the contact on the sheet metal (11), and latex balloon (13), gas blow pipe (14), gas hole (2) is formed.When the player blew to gas hole (2), the pressure in the air bag that communicates with it (13) increased, and air bag is splashed bloated, and elastic sheet metal (10), (12) are forced outwardly extension, to making K ₁Closed.Obviously the same K when air-breathing with stationary state ₁All be in off-state.K ₂Be air-breathing sensitive switch, by the contact (16) on introversion type elastic sheet metal (15), (17) sheet metal, latex balloon (18), air intake duct (19), suction hole (3) is formed.When the player was air-breathing facing to suction hole, the pressure in the air bag (18) reduced, and air bag diminishes.Continue to curve inwardly in elastic sheet metal (15), (17), to making K ₂Closure, obviously the same with stationary state when blowing, K ₂All be in off-state.

With reference to accompanying drawing 1.

HJ-15 is a kind of CMOS integrated circuit of simulating piano sound, and it exports 15 whole tone keys, and behind any bond bundle of every bullet, power supply can be closed automatically, and interior circuit is established the preposition amplification of one-level, adds a positive-negative-positive power tube and promotes the loudspeaker pronunciation.K _A, K _B, K _C, K _DFor pressing the general formula keyswitch, respectively with R _a, R _b, R _c, R _dForm tone control circuit, K _fBe beat accompaniment tap switch, circuit can carry out the accompaniment of 1/2 and 3/4 beat after connecting.This circuit has automatic shutdown function, and quiescent current is 1uA.Power supply is taked two joint No.5 cell power supplies.K ₁, K ₂, K ₃... K ₁₅Being the scale gauge tap, is K with reference to accompanying drawing 2 ₁, K ₂Be the representative of scale gauge tap, they are installed in the both sides that electronic organ blows, inhales the capsule of taking offence respectively, are subjected to the control of air bag internal gas pressure size, when the player according to music score blow, when air-breathing, they are conducting clocklike.Thereby can play out different scales.

Claims

1, a kind of and traditional mouth organ playing method is identical, has the hand acoustic electronic organ that plays the electronic piano, form by shell (1), pilot lamp (8), loudspeaker (9), beat key (6), tone key (5), power switch (7) and electronics integrated audio circuit, it is characterized in that:

A, a row is set for playing the blowing of usefulness, suction hole (2) and (3) in the position, front lower place of shell (1), they are spaced, and wherein scale 1,3,5 is a blowing sound, and 2,4,6,7, be sound-absorbing.

B, K ₁Be the air blowing sensitive switch, by the contact (11) on elastic sheet metal (10), (12) sheet metal, latex balloon (13), gas blow pipe (4) and the gas hole (2) that is communicated with it are formed.

C, K ₂Be air-breathing sensitive switch, reach the suction hole (3) that is communicated with it by the contact (16) on elastic sheet metal (15), (17) sheet metal, latex balloon (18), air intake duct (19) and form.

2, according to claim 1, electronics integrated audio circuit is made of the mellotron integrated circuit.
