Abstract
The present invention provides a kind of melodious type sport whistle, including mouthpiece, and the mouthpiece is connected to the rounded resonant cavity of longitudal section；The mouthpiece and resonant cavity are fixedly connected with wedge block, and resonant cavity is provided with gas outlet in the back upper place of wedge block；Movable bead is equipped in the resonant cavity；It is hollow cavity inside the activity bead, and the activity bead is equipped with an air inlet hole.The whistle roundness degree with higher that the melodious type sport whistle generates, more traditional whistle are more melodized.
Description
Technical field
The present invention relates to sports goods fields, particularly, are related to a kind of melodious type sport whistle.
Background technique
In teaching process of physical education, whistle is a kind of basic articles, is mainly used for hair number order；Traditional whistle includes one
Mouthpiece and a resonant cavity, the air-flow for being blown into whistle from mouthpiece are ripped in the junction of mouthpiece and resonant cavity by wedge, a part
It is flowed out from the gas outlet above resonant cavity, another part enters resonant cavity, shakes the bead in resonant cavity continuously, continuously to change
Become the cavity shape of resonant cavity, to make resonant frequency consecutive variations, sharp sound, makes to avoid the dullness that whistle issues
Ear is difficult to receive.However, current whistle bead have very symmetrical shape, cause wind-force for bead effect more
Limited, more air-flow acts on around bead without the displacement generation to bead, therefore it is significantly fast that bead can not be made to generate
Speed movement, makes the shape of resonant cavity internal cavity be difficult to quickly and significantly change；Therefore, the mellow and full degree of whistle also more has
Limit, needs to further decrease the sharp sense of whistle, keeps it more melodious.
Summary of the invention
In view of the above-mentioned problems, the purpose of the present invention is to provide a kind of melodious type sport whistle, the melodious type sport whistle
The whistle of generation roundness degree with higher, more traditional whistle are more melodized.
The technical solution adopted by the present invention to solve the technical problems is: the melodious type sport whistle includes mouthpiece, described
Mouthpiece is connected to the rounded resonant cavity of longitudal section；The junction of the mouthpiece and resonant cavity is fixed with wedge block, and altogether
Vibration chamber is provided with gas outlet in the back upper place of wedge block；Movable bead is equipped in the resonant cavity；It is sky inside the activity bead
The chambers of the heart, and the activity bead is equipped with an air inlet hole.
Preferably, being additionally provided with an interior spheroid inside the activity bead；Further, the interior spheroid is also hollow
Ball.
Preferably, it is described activity bead hollow cavity cavity wall on be formed with the rib or fin for protruding from cavity wall, with into
One step improves the air-flow into hollow cavity to the thrust of movable bead.
The beneficial effects of the present invention are: the melodious type sport whistle is more into the air-flow in resonant cavity when blowing a whistle
A part will enter in the hollow cavity of movable bead, so that the thrust to movable bead is substantially improved, while again substantially not
The resistance of influence activity bead and resonance cavity wall, so that movable bead carries out substantially and quickly moving in resonant cavity, from
And improve the mellow and full degree of birdie；Also, it is empty that the hollow cavity of movable bead itself increases total resonance in entire resonant cavity again
Between, resonance effect can be made more preferably, this further improves the sound quality of birdie, keeps its melodized.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of this melodious type sport whistle embodiment one.
Fig. 2 is the structural schematic diagram of this melodious type sport whistle embodiment two.
Specific embodiment
Present invention will be further explained below with reference to the attached drawings and examples:
Embodiment one:
In embodiment one shown in Fig. 1, which includes mouthpiece 1, and the mouthpiece 1 is connected to one and indulges
The rounded resonant cavity 2 in section；The junction of the mouthpiece 1 and resonant cavity 2 is fixed with wedge block 3, and resonant cavity 2 is in wedge block
3 back upper place is provided with gas outlet 20；Movable bead 4 is equipped in the resonant cavity 2；It is hollow cavity inside the activity bead 4, and
The activity bead 4 is equipped with an air inlet hole 40.
It is small that above-mentioned melodious type sport whistle will enter activity when blowing a whistle, into more a part of air-flow in resonant cavity 2
In the hollow cavity of ball 4, so that the thrust to movable bead 4 be substantially improved, while movable bead 4 is had substantially no effect on again together
The resistance of vibration 2 inner wall of chamber, so that movable bead 4 carries out substantially and quickly moving in resonant cavity, to improve the circle of birdie
Profit degree；Also, the hollow cavity of movable bead 4 itself increases total resonant space in entire resonant cavity 2 again, and resonance can be made to imitate
More preferably, this further improves the sound quality of birdie to fruit, keeps its melodized.
Embodiment two:
For embodiment two shown in Fig. 2, what is different from the first embodiment is that being additionally provided with one inside the activity bead 4
Interior spheroid 5, the sphere diameter of the interior spheroid 5 are greater than the aperture of the air inlet hole 40.By this scheme, the interior spheroid 5 again can be in work
Continuously change the spatial form of hollow cavity in the hollow cavity of dynamic bead 4, to make the resonant space shape of movable bead inside and outside
It changes simultaneously, keeps total resonant space shape more rich and changeful, and variation is more rapid, to further increase whistle
Sound quality；The interior spheroid 5 is also hollow sphere, keeps its weight smaller, is easy to move.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all in spirit of the invention and
Within principle, made any modification, equivalent replacement be should all be included in the protection scope of the present invention.
