Abstract
The utility model provides an air controlled tightening auricle earphone. Intending to solve the problem that the external earphone casing of an air controlled tightening auricle unit is easy to damage and is not artistic in appearance, the utility model discloses an air controlled tightening auricle earphone, comprising an earphone casing and an air controlled tightening auricle unit. The air controlled tightening auricle unit comprises a one-way intake valve, an airbag body, a one-way exhaust valve, a blowout switch and an airbag cover. The one-way intake valve is arranged on the airbag body, the airbag body is connected to the one-way exhaust valve, the one-way exhaust valve is connected to the blowout switch, and the blowout switch is connected to the airbag cover. The utility model is characterized in that the air controlled tightening auricle unit is arranged in the earphone casing. The built-in air controlled tightening auricle unit of utility model is more artistic in appearance than the earphone with an external air controlled tightening auricle unit, and the earphone casing can effectively protect the air controlled tightening auricle unit and reduce failures.
Description
Technical field
The present invention relates to a kind of earphone.
Background technology
Existing earplug earphone is generally the rigid plastics material, fills in ear and easily drops out in ear.In order to prevent that the earplug earphone from dropping out in ear, people overlap a sponges cover usually to prevent coming off of earphone on earphone outer covering.This sponges cover is extremely thin, tears because of carelessness when people move back and forth earphone easily, even damages in the process that earphone moves in ear a period of time of after having used, very without usefulness.And the in fact very easy suction of this earphone covers is grey, multiplies bacterium, and is unhygienic, is unfavorable for the cleaning and the health in ear chamber.
The inventor has designed a kind of earphone for this reason, and its number of patent application is 200620096857.9, and the applying date is on May 22nd, 2006.This earphone has adopted a kind of gas device, the principle of this device as shown in Figure 3, the gas device comprises breather check valve, air bag body, outgassing nonreturn valve, air escape cock, Air sac cover, wherein the air bag body is provided with breather check valve, air bag is connected with outgassing nonreturn valve, outgassing nonreturn valve is connected with air escape cock again, and air escape cock links together with Air sac cover then.The structure of this earphone as shown in Figure 4, this patent application document provides a kind of structure of external gas device.External mode is so obviously lost attractive in appearance, and the gas device is owing to be exposed to the outer easy damage of thinking of earphone case.
Summary of the invention
The objective of the invention is for to solve number of patent application be the easy damage that causes of the external earphone case of gas device in 200620096857.9 earphones and be short of problem attractive in appearance.The present invention proposes a kind of gas for this reason, comprise earphone case and gas device, described gas device comprises breather check valve, air bag body, outgassing nonreturn valve, air escape cock, Air sac cover, wherein the air bag body is provided with breather check valve, described air bag body is connected with described outgassing nonreturn valve, outgassing nonreturn valve is connected with described air escape cock again, air escape cock links together with described Air sac cover then, it is characterized in that: described gas device is located in the described earphone case.
The invention provides the Headphone structure of two kinds of built-in gas devices a kind of is that described air escape cock is located on the earphone case, and described air bag body is the hard piston structure, and described air bag body is furnished with the piston rod of air in the compressive charge pneumatophore; Another kind is that described air escape cock is located on the earphone case, and described air bag body is soft elastomer, is provided with the line of rabbet joint on described earphone case, and the line of rabbet joint is built-in with the wheel of calming the anger, and calms the anger wheel on enclosure interior is placed in described air bag body.
The built-in gas device of the present invention, more attractive in appearance than the earphone of number of patent application 200620096857.9, and also earphone case can play good protection to the gas device, can reduce fault.

Embodiment
Embodiment one, as shown in Figure 2.Earphone case 1 encases the gas device.The gas device comprises breather check valve 5, air bag body 6, outgassing nonreturn valve 8, air escape cock 7, Air sac cover 3, air bag body 6 is provided with breather check valve 5, air bag body 6 is connected with outgassing nonreturn valve 8 by tracheae 4, outgassing nonreturn valve 8 is connected with air escape cock 7 again, and air escape cock 7 links together by tracheae with Air sac cover 3 then.Air bag body 6 is the hard piston structure, and its underpart is furnished with the piston rod 9 of air in the compressive charge pneumatophore.
The use of present embodiment.Promote piston rod 9 in the air bag body, outgassing nonreturn valve 8 is opened, and breather check valve 5 is closed, and gas enters Air sac cover 3, and this moment, Air sac cover can make earphone compact in people's auricle.Before taking off earphone, open air escape cock earlier, air communicates with atmosphere in the Air sac cover 3, and when taking out earphone, Air sac cover can shrink by automatic deflation.Drop-down piston rod 6, outgassing nonreturn valve 8 is closed, and breather check valve 5 is opened, and atmospheric air enters in the air bag body 6.Finish the gas replenishment process of air bag body 6.
Embodiment two, as shown in Figure 1.Earphone case 1 encases the gas device.The gas device comprises breather check valve 5, air bag body 6, outgassing nonreturn valve 8, air escape cock 7, Air sac cover 3, air bag body 6 is provided with breather check valve 5, air bag body 6 is connected with outgassing nonreturn valve 8 by tracheae 4, outgassing nonreturn valve 8 is connected with air escape cock 7 again, and air escape cock 7 links together by tracheae with Air sac cover 3 then.Air escape cock 7 is located on the earphone case 1, and air bag body 6 is soft elastomer, is provided with the line of rabbet joint on earphone case 1, and the line of rabbet joint is built-in with the wheel 10 of calming the anger, and calms the anger wheel 10 on enclosure interior is placed in air bag body 6.
The use of present embodiment.Calm the anger with finger push and upwards to slide in wheel 10 the lines of rabbet joint on housing, wheel 10 parts that contact with air bag body 6 of calming the anger can overstock soft inflated pneumatophore 6, make it wash outgassing nonreturn valve 8 open, this moment, breather check valve 5 was closed, gas is washed open and is entered Air sac cover 3 behind the outgassing nonreturn valve 8 and make its bulging, thereby earphone is compacted in people's auricle.Before taking off earphone, open air escape cock 7 earlier, air communicates with atmosphere in the Air sac cover 3, and when taking out earphone, Air sac cover can shrink by automatic deflation.Need the rollback wheel 10 of calming the anger to the inflation of air bag body 6, breather check valve 5 is opened, outgassing nonreturn valve 8 is closed, the air elastic return original form that soft inflated pneumatophore 6 sucks in the atmosphere.
