Abstract

The present invention provides one kind can modify tone training whistle, including mouthpiece, and the mouthpiece is connected to a rounded resonant cavity of vertical section；The mouthpiece is fixedly connected with wedge block with resonant cavity, and resonant cavity is provided with gas outlet in the back upper place of wedge block；Irony bead is provided with the resonant cavity；The side of the resonant cavity has the unlimited sliding chamber in an outer end, and constraint has a permanent magnetic slider in the sliding chamber, and supporting stage clip is provided between the permanent magnetic slider and the bottom in sliding chamber.The training whistle that can modify tone can be conveniently adjusted the tone of slightly sound, to express different training orders.

Description

Can be modified tone training whistle

Technical field

The present invention relates to sports goods field, especially, it is related to a kind of training whistle.

Background technology

In teaching process of physical education, whistle is a kind of basic articles for use, is mainly used in hair number order；Traditional whistle includes one Mouthpiece and a resonant cavity, the air-flow for being blown into whistle from mouthpiece are ripped with the junction of resonant cavity in mouthpiece by wedge, a part Gas outlet outflow from above resonant cavity, another part enters resonant cavity, the bead in resonant cavity is continuously rocked, continuously to change Become the cavity shape of resonant cavity, so that resonant frequency consecutive variations, dull and sharp sound is sent to suppress whistle, make ear Piece it is difficult to receive.

The whistle traditional for this kind, in the case where strength of blowing a whistle determines, volume and the tone of whistle are substantially steady Fixed, therefore different orders cannot be expressed with a sound whistle, it is more difficult to meet abundant training active rule.

The content of the invention

Regarding to the issue above, can modify tone training whistle, the training whistle that can modify tone it is an object of the invention to provide one kind The tone of slightly sound can be conveniently adjusted, to express different training orders.

The technical solution adopted for the present invention to solve the technical problems is：The training whistle that can modify tone includes mouthpiece, described Mouthpiece is connected to a rounded resonant cavity of vertical section；The mouthpiece is fixedly connected with wedge block, and resonance with resonant cavity Chamber is provided with gas outlet in the back upper place of wedge block；Irony bead is provided with the resonant cavity；The side of the resonant cavity has one The unlimited sliding chamber in individual outer end, constraint has a permanent magnetic slider in the sliding chamber, is set between the permanent magnetic slider and the bottom in sliding chamber There is supporting stage clip.

Preferably, the port in the sliding chamber can be such that thumb scratches into pressing the convenience of the sliding block to ensure.

Preferably, the irony bead is made up of hollow ball, to reduce its weight, it is set easily to be blown.

Preferably, the periphery in the sliding chamber is equipped with an induction coil, the induction coil is exported to located at the mouth A LED outside the whistle；During whistling, because the position of irony bead continuously and rapidly changes, irony bead Magnetic field consecutive variations between permanent magnetic slider, so that the induction coil forms induced-current, to light the LED, from And the alarming effect of whistle is further improved, in the case that whistle is more particularly in the zone of action, it is easier to which distinguishing is The whistle who coach blows.

The beneficial effects of the present invention are：This can modify tone training whistle in use, the permanent magnetic slider not by Be pressed into sliding chamber it is inner when, because from the distant of irony bead, irony bead is smaller by its magnetic attraction, therefore in resonance The resistance of motion in chamber is smaller, when blowing a whistle, can quickly change the cavity shape of resonant cavity, relatively overcast mellow and full to be formed Birdie；And when permanent magnetic slider be pressed into sliding chamber it is inner when, because permanent magnetic slider and the distance of irony bead are obviously reduced, make The magnetic attraction that irony bead is subject to is significantly improved, the retard motion of irony bead, the cavity for making it quickly to change resonant cavity Shape, so as to form relatively sharp high pitch；As can be seen here, the training whistle that can modify tone can be conveniently adjusted the sound of slightly sound Adjust, to express different training orders.

Brief description of the drawings

Fig. 2 be originally can modify tone training whistle embodiment one end to structural representation.

Fig. 3 be originally can modify tone training whistle embodiment two end to structural representation.

Specific embodiment

The present invention is further described with reference to the accompanying drawings and examples：

Embodiment one：

In the embodiment one shown in Fig. 1, Fig. 2, the training whistle that can modify tone includes mouthpiece 1, and the mouthpiece 1 is connected to one and indulges The rounded resonant cavity 2 of tangent plane；The mouthpiece 1 is fixedly connected with wedge block 3, and resonant cavity 2 in wedge block 3 with resonant cavity 2 Back upper place be provided with gas outlet 20；Irony bead 4 is provided with the resonant cavity 2；The side of the resonant cavity 2 has an outer end Constraint has a permanent magnetic slider 6 in unlimited sliding chamber 5, the sliding chamber 5, is provided between the permanent magnetic slider 6 and the bottom in sliding chamber 5 Supporting stage clip 7.

Above-mentioned modified tone training whistle, the port in the sliding chamber 5 can be such that thumb scratches into ensure that the pressing permanent magnetism is slided The convenience of block 6；The irony bead 4 is made up of hollow ball, to reduce its weight, it is easily blown.

Above-mentioned to modify tone training whistle in use, the permanent magnetic slider 6 is not pressed into the inner in sliding chamber 5 When, because from the distant of irony bead 4, irony bead 4 is smaller by its magnetic attraction, therefore the motion resistance in resonant cavity 2 Power is smaller, when blowing a whistle, can quickly change the cavity shape of resonant cavity 2, to form relatively overcast mellow and full birdie；And ought be forever Magnetic slider 6 be pressed into sliding chamber 5 it is inner when, because permanent magnetic slider 6 is obviously reduced with the distance of irony bead 4, make irony small The magnetic attraction that ball 4 is subject to is significantly improved, the retard motion of irony bead 4, the cavity shape for making it quickly to change resonant cavity 2 Shape, so as to form relatively sharp high pitch；As can be seen here, the training whistle that can modify tone can be conveniently adjusted the tone of slightly sound, To express different training orders.

In the embodiment two shown in Fig. 3, the periphery in the sliding chamber 5 is equipped with an induction coil 8, the induction coil A LED9 of 8 outputs extremely outside the whistle；During whistling, because the position of irony bead 4 is continuous and fast Change fastly, the magnetic field consecutive variations between irony bead 4 and permanent magnetic slider 6, so that the induction coil 8 forms induced electricity Stream, to light the LED9, so that the alarming effect of whistle is further improved, particularly whistle is more in zone of action In the case of, e.g., on same playground, when student is trained, birdie is often relatively more mixed and disorderly, is possible to mistake the whistle often for multidigit coach Sound；And after working as whistle sound, a small meeting youngster will be also moved under effect of inertia due to irony bead 4, therefore after birdie is heard, By observing the flash of light of whistle, it is easier to distinguish to be who trains the whistle blown.

The foregoing is only presently preferred embodiments of the present invention, be not intended to limit the invention, it is all it is of the invention spirit and Within principle, any modification, the equivalent made should be included within the scope of the present invention.
