Dynamic cavity wall setting, the outboard end of sealing column stretch out in the outside of gas cylinder.
The gas-guide tube and gas cylinder are all made of metal tube as a preferred technical solution, and gas-guide tube one end is inserted in
The second through-hole and gluing water-stop that air guide drum outer wall opens up are fixed, and the other end is inserted in the third through-hole opened up on annular air-pocket
And gluing water-stop is fixed.
The outboard end of the earphone outer covering passes through spiral shell by a cover plate for sealing, the cover board as a preferred technical solution,
The installation cavity of line and earphone outer covering is tightly connected, and sealing column one end passes through cover board and stretches out in the outside of cover board, sealing column
External extension end be a spherical.
The beneficial effects of the utility model are: the utility model uses an annular air-pocket, can be carried out for different crowds
It wears, increases leakproofness when wearing, prevent outer gas stream from pouring into ear, while loudspeaker horn is installed on three gas-guide tubes
On, the impact resistance after increasing installation eliminates the setting of bracket.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, it is also possible to obtain other drawings based on these drawings.
Fig. 1 is the overall structure diagram of the utility model；
Fig. 2 is that the utility model removes the schematic diagram of internal structure after cover board；
Fig. 3 is the gas-guide tube of the utility model and the assembling structure schematic diagram of annular air-pocket.
Specific embodiment
All features disclosed in this specification or disclosed all methods or in the process the step of, in addition to mutually exclusive
Feature and/or step other than, can combine in any way.
Any feature disclosed in this specification (including any accessory claim, abstract and attached drawing), except non-specifically chatting
It states, can be replaced by other alternative features that are equivalent or have similar purpose.That is, unless specifically stated, each feature is only
It is an example in a series of equivalent or similar characteristics.
As shown in Figure 1-Figure 3, including earphone outer covering 1, the outer wall of earphone outer covering 1 open up a ring annular groove, set in annular groove
An annular air-pocket 2 is set, 2 inner hollow of annular air-pocket simultaneously has a closed air storing cavity (not shown), has inside earphone outer covering 1
There is an installation cavity 6,6 inner wall of installation cavity offers at least three first through hole, is respectively provided with an air guide across each first through hole
Pipe 3, one end of gas-guide tube 3 connect conducting with annular air-pocket 2, and the other end connects a gas cylinder 4, has one inside gas cylinder 4
Movable chamber 5, movable chamber 5 is interior to be packed into a sealing column 7, pushes sealing column 7 that the air in movable chamber is injected into annular air-pocket, ear
One loudspeaker horn 12 is installed, the outer casing stand of loudspeaker horn 12 is fixedly installed at least three air guides inside machine shell 1
In the outside wall surface of pipe 3.
Wherein, it is welded and fixed by glue between the outer casing stand of loudspeaker horn 12 and three gas-guide tubes 3, loudspeaker
Loudspeaker 12 are installed on gas-guide tube, eliminate the setting of bracket, while entire loudspeaker horn 12 is hanging, such earphone is falling
When falling, the impact to loudspeaker horn 12 can be substantially reduced, increases service life.
Wherein, a sealing piston 11 is arranged in the inserting end of sealing column 7, and 11 outer wall of sealing piston is close to 5 inner wall of movable chamber
Setting, the outboard end of sealing column 7 stretch out in the outside of gas cylinder.Sealing piston 11 can be close to inner wall, therefore regardless of pushing
It to which, can be kept fixed, will not be subjected to displacement, since after being pushed into sealing column, the gas in movable chamber can enter annular
In air bag, air bag air inlet expansion is in close contact with ear, and annular air-pocket has bounce due to expanding at this time, air-flow meeting at this time
It is back in movable chamber, sealing piston is pushed by this strand of back draught in order to prevent, the friction of sealing piston and movable cavity wall
Power must be done greatly, and only Manual-pushing is.
Wherein, gas-guide tube 3 and gas cylinder 4 are all made of metal tube, and 3 one end of gas-guide tube is inserted in 4 outer wall of gas cylinder and opens up
The second through-hole and gluing water-stop fix, the other end is inserted in the third through-hole that opens up on annular air-pocket 2 and gluing water-stop
It is fixed.
The outboard end of earphone outer covering is sealed by a cover board 8, and cover board 8 is sealed by the installation cavity of screw thread and earphone outer covering 1
Connection, 7 one end of sealing column pass through cover board and stretch out in the outside of cover board, and the external extension end of sealing column 7 is a spherical.
The beneficial effects of the utility model are: the utility model uses an annular air-pocket, can be carried out for different crowds
It wears, increases leakproofness when wearing, prevent outer gas stream from pouring into ear, while loudspeaker horn is installed on three gas-guide tubes
On, the impact resistance after increasing installation eliminates the setting of bracket.
Above description is only a specific implementation of the present invention, but the protection scope of the utility model is not limited to
In this, any change or replacement expected without creative work be should be covered within the scope of the utility model.
