Abstract
A horn reed, the front of the reed body is provided with a suction nozzle, and the intermediate section is provided with an air cavity which has an upper opening. The characterized in that is the rear portion of the reed body is provided with a gassing barrel body, one port of the gassing barrel body is connected with the feed body, the other port is open, and the gassing open of the gassing barrel body is positioned on the back of the air cavity upper shed. A light rolling ball is arranged in the air cavity, the light rolling ball is provided with a radial through-hole. The outer of the reed is provided with a suspension loop. After the horn reed employing the structure, reduce stimulation of the eardrum when the whistle blower whistling, effectively protecting the auditory acuity, simultaneously try to make the whistle divergent to the target orientation, increase the propagation distance.
Description
Technical field
A kind of whistle of manually blowing with mouth.
Background technology
The application scenario at the whistle is a lot.But there is shortcoming in the present whistle; Ear-drum stimulation to the person of blowing a whistle is too big, so that the personnel on some posies dare not blow more.Just need constantly blow a whistle among one day such as the traffic police on the road of city and traffic management assistant, blow at the end of the day that hearing significantly weakens, many people's reflections are felt dizzy.In every athletic competition, because spectators are many, noise is too big, makes the sportsman can't hear referee's whistle, the influence match, and this is that the whistle propagation distance causes inadequately.
The utility model content
The technical problems to be solved in the utility model provides a kind of stimulation that alleviates the person's of blowing a whistle ear-drum, and whistle has directivity simultaneously, it is dispersed to target as far as possible, and make the farther a kind of whistle of propagation distance.
For solving the problems of the technologies described above, the body front portion, the whistle at the loudspeaker of the present utility model whistle is provided with admission piece, and the middle part is provided with the air cavity of band upper shed, and it is characterized in that: the rear portion of this whistle body is provided with the cylindrical shell of giving vent to anger, one end of this cylindrical shell of giving vent to anger is connected with whistle body, and the other end opens wide.The give vent to anger gas outlet of cylindrical shell is positioned at the rear of air cavity upper shed.Light body spin is housed in the air cavity, and this light body spin is provided with radial direction through hole.Whistle external body is provided with link.After such structure is adopted at the loudspeaker whistle, make the person of blowing a whistle when blowing a whistle, reduce stimulation, protected hearing effectively, whistle is dispersed towards target direction as far as possible, increased propagation distance ear-drum.

Fig. 2 is the upward view at the utility model loudspeaker whistle.
Fig. 3 is the A-A cut-open view of Fig. 2.
Fig. 4 is the stereographic map at the utility model loudspeaker whistle.
Embodiment
As can be seen from Figure 3, the air communication that the user blows into is crossed the admission piece 1 of body front portion, the whistle, and air cavity upper shed 5 enters air cavity 2.Light body spin 6 in the air cavity 2 is rolled unsteady under the air-flow effect, makes it disturbing flow, and whistle is changed rhythmically, makes it soft, weakens high pitch simultaneously.In order to alleviate spin weight, increase rolling effect, radially be provided with through hole 7 at it.Discharge the gas outlet 4 of air-flow through being positioned at air cavity 2 upper sheds 5 rears.Because the rear portion of whistle body is provided with the cylindrical shell 3 of giving vent to anger, and makes air-flow increase the transmitting range of sound along the cartridge openings directional divergence, reduced to user's head passing the acoustic energy that goes simultaneously effectively.
One end of cylindrical shell 3 is connected with whistle body, and the other end opens wide, and its cross section can be suitable shapes such as rectangle, square, circle, ellipse.Such conversion all drops within the protection domain of the present utility model.Before hanging over brain for convenience, the outside at the whistle is provided with for the link 8 of fastening rope.
