Detailed description of the invention
The explanation of following example is particular implementation that is graphic with reference to add, that implement in order to illustrate the present invention may be used to
Example.The direction term that the present invention is previously mentioned, such as " on ", D score, "front", "rear", "left", "right", " top ", " end " etc., be only
Direction with reference to annexed drawings.Therefore, the direction term of use is to illustrate and understand the present invention, and is not used to limit this
Bright.
Embodiment: as shown in Figure 1 and Figure 2, a kind of explosion-proof wind-tone horn, including air bag 1, bass horn 2, high pitch
Loudspeaker 3 and a breather group 4.
As shown in Figure 3, Figure 4, wherein, the material of this air bag 1 is silicone rubber.This air bag 1 includes by portion 11 1 support
Portion 12 and with a cavity (not shown), being located on supporting part 12 as what portion 11 sealed under this.It is shaped as sphere by portion 11 under this
A part, be therefore cambered surface by the face in portion 11 under this.It is this cavity by the inside surrounded in portion 11 and supporting part 12 under this.
This supporting part 12 be shaped like round platform (without upper table surface), under be sealed in above this round platform (at upper table surface) by portion 11.This is root
Arrange according to human body hand-type, convenient operation.
This air bag 1 also includes gas outlet 15, air inlet 14 and two installation portions 13, gas outlet 15, air inlet 14
And installation portion 13 is all located at the bottom surface of this supporting part 12.This air inlet 14, gas outlet 15 are communicated in this cavity.Air inlet 14 sets
In the middle part of the bottom of air bag 1, and it is positioned in the middle of two installation portions 13.
As it is shown in figure 5, this air inlet 14 includes an one-way ventilating part 16, this one-way ventilating part 16 allows extraneous sky
Gas enters cavity.Concrete, one-way ventilating part 16 includes ventilation part body 161 and an at least one one-way ventilating hole 162.This leads to
Gas part body 161 is assembled to air inlet 14, and this one-way ventilating pore size distribution is on this ventilation part body 161.Wherein, each unidirectional logical
The aperture within the cavity of pore is less than the aperture in the adjacent external world in this one-way ventilating hole.And this one-way ventilating hole is elastic logical
Pore.
This bass horn 2 and this respective inflatable mouth of loudspeaker 3 are communicated to gas outlet 15 by this breather group 4.
Wherein, air bag 1 has elasticity, automatically restores to the original state after air got rid of by air bag 1.Down by the elasticity in portion 11 more than propping up
The elasticity of support part 12, the rigidity of supporting part 12 is more than lower by portion 11.
During concrete operations, pressing the lower by portion 11 of this air bag 1, the air in the cavity of this air bag 1 is discharged through gas outlet 15,
Gas simultaneously enters bass horn 2 and loudspeaker 3, bass horn 2 and loudspeaker 3 after entering breather group 4 and sends difference
Sound (frequency different and/or volume different)；Stop this air bag 1 manual pressure afterwards, this air bag 1 in ambient atmosphere and
Automatically restore to the original state under the elastic reaction of self.During recovery, the face, hole in one-way ventilating hole is softened (because of sky by atmospheric pressure effect
Certain pressure differential is had) between chamber and atmospheric pressure；Atmosphere enters cavity.After this air bag 1 restores to the original state automatically, should
The air pressure of cavity keeps consistent with extraneous atmospheric gas pressure, and now, one-way ventilating hole is shunk, and the aperture being positioned at cavity infinitely connects
It is bordering on the state of closing.
These are only preferred embodiment of the present utility model, not in order to limit this utility model, all in this practicality
Any amendment, equivalent and the improvement etc. made within novel spirit and principle, should be included in guarantor of the present utility model
Within the scope of protecting.
