Abstract
A kind of mouthpiece (1) that is used for wind instrument, comprise: an air intake opening (5), a gas outlet, one is used for gathering the cavity that is blown into the liquid that air-flow contains, with a closed air flue (2), air flue is positioned at mouthpiece, and leads to the gas outlet, it is characterized in that air intake opening interconnects by cavity and air flue.When playing wind instruments, when the air communication that the bassoonist is blown into is crossed cavity, allow fluid accumulation in cavity, leave mouthpiece through air flue then.The air-flow that has reduced moisture has been avoided the influence to tonequality, so after playing wind instruments a very long time, just need to remove hydrops.Equally also can reduce to be blown into air-flow, in order to avoid the bassoonist who lacks experience is firmly excessive when playing wind instruments.
Description
Involved in the present invention is the wind instrument with mouthpiece.Mouthpiece is meant bassoonist's that part with mouthful blowing instrument.In general, the mouthpiece shape of musical instrument not only will make bassoonist oral cavity when playing wind instruments feel comfortable, also requires it that the outward appearance that makes the people pleasing is arranged.In addition, mouthpiece partly has an air flue, can impel the gas cambium layer to flow to into body.
The straight flute of common octal has the air flue (2) of a through state, as shown in Figure 1.The air-flow that blows out in the mouth when bassoonist plays is through air flue, locate to be separated at vent plug (3), vent plug (3) is that the edge by the vestibule (4) of straight flute body is constituted, it is positioned at the place near mouthpiece, air-flow has produced local air pressure vibrations there, this acts in the body (gas column) of musical instrument and has produced sympathetic response, amplifies, thereby produces musical sound.
After the straight flute of this octal had only been played wind instruments a few minutes, the air-flow that blows out in bassoonist's mouth can condensation in the air flue of musical instrument, forms aqueous vapor.These aqueous vapors and the saliva that builds up in air flue lumps together, arrived to a certain degree will obstructing airway path, the air-flow of impact on vent plug causes interference, this interference to air-flow, the audio distortions in the time of can musical instrument being played wind instruments.
Above-mentioned these liquid also can flow into straight flute body, so must often dispose the liquid that these gather, this is to the player, and particularly when playing wind instruments, remove these liquid is a headachy thing really.And after repeatedly using, these liquid also can damage the inwall of woodwind instrument.
The preheating mouthpiece is a kind of method that may alleviate this degree of congestion, this is particularly useful to woodwind instrument, to non-woodwind instrument, and the plastic tube musical instrument of often playing wind instruments such as children, this choking phenomenon will be even more serious, because the time-consuming mouthpiece that removes the economizer bank musical instrument of their not conferenceization.
The straight flute of a kind of improved octal has been widened air flue in order to overcome the problem of above-mentioned existence, but has brought new problem, has weakened gas-flow resistance because of it, and tonequality, tone are degenerated.This is especially true concerning the bassoonist who lacks experience.
Therefore one object of the present invention just is intended to eliminate these defectives.
According to the present invention, a kind of mouthpiece that is used for wind instrument that we provided, it comprises: an air intake opening, a gas outlet, one is used for gathering the cavity that is blown into the liquid that air-flow contains, with a closed air flue that is positioned at mouthpiece and leads to the gas outlet, the gas import interconnects by cavity and air flue.
We also provide a kind of wind instrument with above-mentioned mouthpiece.
According to a further aspect in the invention, we provide a kind of method that reduces the choking phenomenon that causes because of the liquid of staying in the wind instrument again, comprise: when the air communication that enters air intake opening is crossed cavity in the mouthpiece, allow be blown into the fluid accumulation that contains in the air-flow in cavity, make the air-flow that reduced moisture leave mouthpiece then along the air flue of sealing.
Air flue is a straight-through passage, is used for producing laminar flow, flows to the vent plug in the body.This air flue is a narrow pipeline, and its cross section is rectangle or other shapes.Air flue accounts for the part of mouthpiece total length or is actually total length, extends to the gas outlet of mouthpiece.Mouthpiece can have an inlet channel, comes steering current to enter in the cavity, the circuitous then air flue that flow to widely differently.Be blown into moisture excessive in air-flow condensation on the mouthpiece inside surface, formed small water droplet, these little water droplets accumulate in the bottom of cavity, its result, be actually reduced moisture air-flow along air flue, lead to the gas outlet of mouthpiece, blow on vent plug, so just alleviated the choking phenomenon in the air flue.Because the moisture that accumulates in the cavity can not influence the musical sound that sends when wind instrument is played wind instruments, the quality of end musical sound equally just can not fallen yet.Accumulate in the moisture in the cavity, can be eager often to dispose, the player can think at him and when an opportunity arises they thrown away from cavity, disposes.Owing to solved the obstructing problem in the air flue in fact, do narrowlyer so air flue can be had ready conditions than the air flue of common wind instrument, so just can produce desirable additional airflow resistance, this point is particularly desirable to the bassoonist who lacks experience.We can also increase or change the resistance of air-flow with the method for the size of size that reduces air flue air intake opening place bore and/or inlet channel bore.
According to the overall width of mouthpiece, can pacify the lastblock barrier sheet, so just can stop the moisture that gathers, in order to avoid they can flow on air flue and/or other surfaces accidentally, be used to cause the condensation of moisture just as the fin that can be installed in cavity bottom.
The mouthpiece of this musical instrument can be used for the wind instrument of any big ting model, is particularly useful for the wind instrument of straight flute one class of octal.The body of mouthpiece and/or musical instrument can be used the manufacturings of timber, ivory, metal or other solid materials, is shaped by artificial or machining.But preferably adopt plastics, because plastics can be used to produce in a large number the wind instrument of straight flute one class of octal.Mouthpiece can be divided into two kinds of patterns: a kind of is that permanent set is on musical instrument; Another kind is to remove from musical instrument.Mouthpiece also can be such, and promptly air flue and musical instrument end are in aggregates.
Specific embodiments of the invention are described below with reference to the drawings:
The head of shown in Figure 1 is a common straight flute of octal.
The outboard profile that shown in Figure 2 is according to first embodiment of mouthpiece of the present invention.
Fig. 3 represents is that embodiment shown in Figure 2 is by line II-sectional view that II intercepts.
Fig. 4 represents is the schematic perspective view of Fig. 2 and mouthpiece shown in Figure 3.
Fig. 5 is according to another kind of embodiment of the present invention with what show.
As shown in Figure 2, mouthpiece (1) has a cavity (7), comprises a straight air duct (2), and it is a flat rectangular duct, extends to gas outlet (6) from contiguous inlet channel (5a).For clarity sake, with Fig. 1 in corresponding parts mark with same numeral.Cavity (7) accounts for the inner sizable part of mouthpiece.The outer wall of mouthpiece is made crooked shape, and keeping their conventional shape, but this is not essential to the invention.Surround the outer wall of inlet channel (5a), make the hook-bill shape of point image bird, be convenient to like this play wind instruments.
Fig. 4 has clearly illustrated the concrete structure of this embodiment, and it forms (only for needs are described) by two vertical half blocks.This embodiment can make with two plastic moulds easily, it comprise a mouthpiece cover (1) and with the terminal pneumatic duct in aggregates of body (10).The entrance point of half one (2a) at the bottom of the pneumatic duct, make the shape that the projection (5b) that adjoins with it is complementary, the lower surface of projection (5b) constitutes the part of inlet channel (5a), and its upper surface helps steering current to flow into the import (9) of pneumatic duct (2).
When playing wind instruments, the air-flow that is blown into, enter the bottom (7a) of cavity (7) by downward-sloping inlet channel (5a), circuitous then the flow through one or both sides of air flue of detouring arrive space (8) at the cavity top, flow into air flue (2) from import (9) again, at this moment air-flow just passes through air flue by common route.
The moisture content that contains in the warm air-flow that is blown into condenses upon in cavity on the colder surface, inside of mouthpiece.The little water droplet that is formed by cohesion accumulates in cavity lower curtate (7a).These liquid that gather can be disposed in due course, perhaps from air intake opening (5) they are thrown away, and so also just being unlikely influences tonequality, reduce the quality of musical sound.Because the problem of liquid lock air flue has been eliminated in fact.
In another embodiment shown in Figure 5, air flue (2) is more a little than the weak point among first embodiment, and it is not connected with the end of inlet channel (5a).
Above-mentioned each embodiment is specially adapted to the straight flute of octal that is pressed into mould.Can use plastics, timber, ivory or other solid materials according to wind instrument of the present invention, make by craft or machining, as use mechanography.
According to mouthpiece of the present invention, can prevent that the moisture that gathers is to the interference of musical sound. After playing wind instruments a very long time, just need to dispose these moisture, can according to different bassoonists' needs, play wind instruments continuously several hours. Owing in fact got rid of the obstruction of mouthpiece air flue, so air-flow can be littler when playing wind instruments, it is excessive that the bassoonist who lacks experience be need not when playing wind instruments with gas.
