Shellfish alreadys exceed the scope that human ear can be born for a long time.Although decibel can be reduced by way of diffusing air current, because gas
Rheology is weak, the situation that thin slice can be caused not shake, thus cause acoustical generator can not sounding awkward situation.
Therefore, exploitation one kind can effectively solve noise and bother owner repeatedly, and the notice of pet can be preferably caused again
Transmitter there is good long-range and realistic meaning.
Utility model content
The utility model provides a kind of high frequency audio acoustical generator, can effectively solve the high-decibel sound that current acoustical generator runs into
The problem of amount harassing and wrecking owner, owner can not be harassed repeatedly by reaching, the doulbe-sides' victory of pet notice can be preferably caused again.
To achieve the above object, the utility model uses following technical scheme：
A kind of high frequency audio acoustical generator, including lid and base, one end of base are provided with inlet channel, and the other end of base is set
There is lid chamber, lid is stretched into lid intracavitary, the center of the lid is provided with the shunting cylinder for splitting streams, shunt cylinder
Inlet channel is stretched into part, and shunting cylinder cooperatively forms the accurate gap of shunting cylinder and inlet channel inwall with inlet channel,
There is the revolution recess of rotatable gas on the periphery of the shunting cylinder, and outlet passageway is surrounded by around lid.
As optimal technical scheme, the revolution recess is located at the medium position of whole high frequency audio acoustical generator, the air inlet
The distance of passage and outlet passageway to revolution recess is equal or close.
It is used as optimal technical scheme, the spherical shape in top of the shunting cylinder.
As optimal technical scheme, the outlet passageway is by some scallop holes being separated into every rib.
As optimal technical scheme, described every rib is brought into close contact with the lid cavity wall of base, the lower end every rib with
The outer wall lower end of revolution recess is flushed.
As optimal technical scheme, accurate gap is unilateral 0.75 millimeter.
As optimal technical scheme, the material of the lid and base is high rigidity plastic cement, is molded by precision die
Arrive.
The beneficial effects of the utility model are：Using the accurate fit clearance between accessory, by external air flow rapidly
Pass through, sending human ear can not perceive, but the high frequency audio that pet can clearly hear；Thoroughly improve because pet is at play acoustic toy
During, because the influence of extruding or the high-decibel sound baiting and produce to owner, but it can effectively attract pet oneself
To the interest of toy.Using the airstream compartment of unique design, extruding supply leatherware cavity can make acoustical generator produce high frequency audio, and
And compared to reed sound-producing device, structure is more stable, will not cry out.

Embodiment
The utility model is described in further detail with accompanying drawing with reference to embodiments.
As shown in figures 1 to 6, high frequency audio acoustical generator includes lid 1 and base 2, and one end of base 2 is provided with inlet channel 2.2,
The other end of base 2 is provided with lid chamber, and lid 1 is stretched into lid intracavitary, and the center of the lid 1 is provided with for splitting streams
Shunt cylinder 1.3, inlet channel 2.2 is stretched into shunting cylinder 1.3 part, shunting cylinder 1.3 and inlet channel 2.2 are cooperatively formed point
The accurate gap 2.1 of cylinder 1.3 and inlet channel inwall is flowed, there is the revolution of rotatable gas on the periphery of the shunting cylinder 1.3
Recess 1.2, outlet passageway 1.1 is surrounded by around lid 1.
The high frequency audio acoustical generator operation principle, air-flow is scoured from inlet channel 2.2, in the resistance of shunting cylinder 1.3
Under gear, high frequency audio is produced along accurate gap 2.1, it is outside along outlet passageway 1.1 then under the revolution of revolution recess 1.2
Diffusion.According to air-flow principle of sound, air velocity is faster, and generation sound frequency is higher, according to air motion principle, acoustical generator
The flow of charge air flow and outlet air-flow is necessarily equal, when accurate gap 2.1 is very small, the air velocity of such position
It is very fast, therefore high-frequency sound can be produced, in the gyration airflow and the air inlet gas in accurate gap 2.1 by the recess 1.2 that circles round
Crossing for stream, influences each other, and produces dither, can obtain high-frequency sound.Particularly, accurate gap 2.1 is unilateral 0.75
Millimeter, by test, the high frequency audio frequency of generation is between 20000 hertz to 50000 hertz, and common human ear None- identified exceedes
20000 hertz of sound, but animal can recognize, can thus be played for animal, but do not influence people to rest.
In the utility model, the high frequency audio acoustical generator sounding is by the air-flow scoured, the high frequency audio sounding
Device is installed on a totally-enclosed or semi-enclosed cavity, and air-flow is produced by extrusion chamber.The cavity is to cause to dote on
All kinds of squeezable toys that thing notes, such as animals shaped cortex toy, animal bites or extruding toy, make air-flow rapidly pass through
High frequency audio acoustical generator and produce high-frequency sound.
Preferably, the revolution recess 1.2 is located at the medium position of whole high frequency audio acoustical generator, such gyration airflow is received outer
Boundary's influence is small so that inlet channel 2.2 is equal or close with the distance of outlet passageway 1.2 to revolution recess 1.2, is easy to send more
Stable high frequency audio.
Preferably, the spherical shape in top of the shunting cylinder 1.3, preferably guides air-flow to accurate gap 2.1.
More particularly, the inlet channel 2.2 is cylindrical channel, and the outer ring of inlet channel 2.2 sets plum blossom-shaped hole, plum
Play mitigation weight and aesthetic in flower-shaped hole.
More particularly, the outlet passageway 1.1 is, by some scallop holes being separated into every rib 1.4, particularly, to pass through 4
Individual to be separated into 4 scallop holes every rib 1.4, described every rib 1.4 is brought into close contact with the lid cavity wall of base 2.It is described every rib 1.4
Lower end is flushed with turning round the outer wall lower end of recess 1.2, and is turned round between the outer wall lower end of recess 1.2 and the bottom presence of lid chamber
Air-flow after for revolution passes through, and air-flow enters outlet passageway 1.1.
More particularly, the material of the lid 1 and base 2 is high rigidity plastic cement, is obtained by precision die shaping.
Above content is to combine specific preferred embodiment further detailed description of the utility model, it is impossible to recognized
Fixed specific implementation of the present utility model is confined to these explanations.For the ordinary skill people of the utility model art
For member, some replacements or substantially modification, and performance or purposes are made on the premise of the design of utility model itself is not departed from
It is identical, it should all be considered as belonging to protection domain of the present utility model.
