Abstract
The utility model relates to a practical whistle, which comprises a suction nozzle which is provided with an air current channel, an air current convolution cavity with an internal moving rolling ball and a hand holding body which is provided with a trumpet hole. The utility model is characterized in that the trumpet hole is arranged on the front lateral face of the air current convolution cavity, the front end portion whose inner portion is provided with an air current channel is arranged on the lateral face on the air current convolution cavity in the form of extending mulch. When in use, sound which is emitted through whistling is scattering and broadcasting around the front portion of the trumpet hole, the practical whistle has little stimulation to the eardrums of users, when in blowing, saliva which gets into the air current convolution cavity is forwards sprayed, which can not be sprayed to the faces of the users, and meanwhile, external water is not easy to get into the air current convolution cavity, the practical whistle is beneficial for guaranteeing work quality, which is permitted to be used in a rainy day without influencing tone quality and sound volume. Compared with a traditional whistle, the practical whistle of the utility model has more scientific and reasonable structure, optimum technique effect and stronger operability and practicability, which is an ideal renewal product of the traditional whistle.
Description
Technical field
The utility model relates to a kind of air-flow sound-producing device, and particularly a kind of texture ratio is more scientific and reasonable, can reduce the practical whistle that stimulates and guarantee the sounding effect to user's ear-drum.
Background technology
Whistle has another name called whistle or is whip, be a kind ofly to make, can blow the implements of sounding with mouth with metal or plastics, be used in daily life morely the teacher convene the student to dress the ranks and practice, the police safeguards social traffic order, the judge sends instructions or the process and some cultural and recreational activities of ruling signal in.Traditional whistle main body is chewed with the airflow cyclotron cavity of interior band free ball and the hand of last band loudspeaker cavity opening (being commonly called as sound mouth) by the air inlet of interior band gas channel and is pinched the body formation, loudspeaker cavity opening is arranged near hand and pinches body and air inlet is chewed on the upper side of junction airflow cyclotron cavity, during work sound by loudspeaker cavity opening with the form of upwards diffusion spatial transmission towards periphery.There are following three shortcomings in the whistle of this version when working: the one, and sound is diffusion upwards, seriously stimulates ear-drum, makes often long-time user cause baryacusia, cause deafness easily, causes nerve problems, influences healthy; The 2nd, loudspeaker cavity opening makes progress, and the user follows a mouth liquid foam that blows out to enter in the airflow cyclotron cavity when blowing with mouth, and can spray from loudspeaker cavity opening along with high velocity air, spills the face to the user, and is very unhygienic; The 3rd, enter the dirigibility that the interior mouth liquid of airflow cyclotron cavity can influence ball to a certain extent, influence the normal flow of air-flow, thereby tonequality can not be guaranteed, the 4th, because loudspeaker cavity opening makes progress, rainy day intakes when using easily, effort when not only using, and influence voice effect.In a word, easy to use and be subjected to widespread use though the whistle of prior art version is simple in structure, volume is little and good and cheap, consider from point of view of practicability such as health hygienic and acoustical quality angles, still owe desirable.
Summary of the invention
The purpose of this utility model be to provide a structure relatively scientific and reasonable, help user health care and guarantee the practical whistle of acoustical quality.
Practical whistle main body of the present utility model is chewed by the air inlet of interior band gas channel and is pinched body with the hand of the airflow cyclotron cavity of interior band free ball and last band loudspeaker cavity opening and constitute, be characterised in that loudspeaker cavity opening is arranged on the leading flank of airflow cyclotron cavity, the leading section that the air inlet of interior band gas channel is chewed is arranged on the upper side of airflow cyclotron cavity with the obducent form that postpones.
In addition, the form that the described coverture of postponing both can air inlet be chewed the leading section continuity is chewed setting with air inlet and is integrative-structure, and form that also can individual member is arranged on the upper side of airflow cyclotron cavity as required.
Based on the of the present utility model practical whistle of above-mentioned design, because loudspeaker cavity opening is arranged on the leading flank of airflow cyclotron cavity, the user chews the sound that sends of blowing a whistle by air inlet and disperses propagation forwards through loudspeaker cavity opening, and is very little to user's ear-drum stimulation; The mouth liquid foam that enters when the user blows in the airflow cyclotron cavity forwards sprays, and can avoid spilling to the user face; Simultaneously, outside water is not easy to enter in the airflow cyclotron cavity, helps guaranteeing work quality, allows to use and do not influence tonequality in the rainy day, efficiently solve the rainy day when using because of blow effort and influence the problem of volume and tonequality of ponding in the airflow cyclotron cavity.In sum, whistle of the present utility model is by changing the position being set and having brought fairly obvious positive technique effect after above the loudspeaker cavity opening coverture being set of loudspeaker cavity opening, and structure is still very simple, easy to process, cost is very low, compares with traditional whistle, and structure is more scientific and reasonable, technique effect is better, having very strong operability and practicality, is a kind of desirable renewal product of traditional whistle, will have vast market and use scape.
Description of drawings
Fig. 1 is the utility model prior art constructions synoptic diagram;
Fig. 2 is the structural representation of the utility model embodiment.
Among the figure:
1. air inlet is chewed 2. loudspeaker cavity openings, 3. hands and is pinched body 4. junctions
5. upper side 6. leading flanks 7. leading sections 8. coverture of postponing
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and exemplary embodiments.
In Fig. 1, existing traditional whistle main body by the air inlet of interior band gas channel chew 1 and the hand of the airflow cyclotron cavity of interior band free ball and last band loudspeaker cavity opening (being commonly called as sound mouth) 2 pinch body 3 and constitute, loudspeaker cavity opening 2 is arranged on to be pinched body 3 near hand and chews on the upper side 5 of 1 junction, 4 airflow cyclotron cavities with air inlet, during work sound by loudspeaker cavity opening 2 with the form of upwards diffusion spatial transmission towards periphery.
In Fig. 2, the utility model whistle main body by the air inlet of interior band gas channel chew 1 and the hand of the airflow cyclotron cavity of interior band free ball and last band loudspeaker cavity opening 2 pinch body 3 and constitute, be characterised in that loudspeaker cavity opening 2 is arranged on the leading flank 6 of airflow cyclotron cavity, the air inlet of interior band gas channel is chewed 1 leading section 7 and is arranged on the upper side 5 of airflow cyclotron cavity with the form of the coverture 8 of postponing.Sound is by the form towards periphery spatial transmission of loudspeaker cavity opening 2 with diffusion forwards during work.In the present embodiment, the described coverture 8 of the postponing form of chewing leading section 7 continuity with air inlet is chewed 1 setting with air inlet and is integrative-structure.
