Description

Silica gel cover and in-ear earphone of prevention in-ear earphone popo noise

[ technical field ] A method for producing a semiconductor device

The utility model relates to an electroacoustic equipment technical field especially relates to a silica gel cover and pleasant earphone of prevention pleasant earphone popo noise.

[ background of the invention ]

In the ear-in type earphone aiming at the wide market, in order to realize the noise reduction effect and especially avoid some popo noises, the leakage design is generally carried out on the front cavity of the earphone, but the current market popular trend is changed to TWS (true wireless stereo), the earphone size is smaller and smaller, the space for the leakage design is not large, especially when some sounding drive units with the size less than 7mm are used, the acoustic leakage design is very difficult to be carried out on the front cavity of the earphone,

[ summary of the invention ]

An object of the application is to provide a silica gel cover and an in-ear earphone of prevention in-ear earphone popo noise, through set up the passageway of making an uproar of falling on the silica gel cover, the passageway intercommunication of making an uproar falls acoustic pipe and external world for acoustic pipe keeps unanimous with external atmospheric pressure, effectively realizes especially making an uproar falling to the popo noise, and saves the design cost of little volume earphone in the aspect of making an uproar falls in the leakage.

The application is realized by the following technical scheme:

the utility model provides a silica gel cover of prevention in-ear earphone popo noise, includes silica gel cover body, silica gel cover body is including cup jointing portion, sound transmission pipeline and gag, set up the intercommunication in the portion of cup jointing sound transmission pipeline and the external passageway of making an uproar that falls.

The silica gel cover for preventing popo noise of the in-ear earphone is characterized in that the sleeving part is in an annular convex shape, and the noise reduction channel is a groove formed in the inner side of the sleeving part.

The silica gel sleeve for preventing popo noise of the in-ear earphone is characterized in that the cross section of the groove is U-shaped.

The silica gel cover for preventing popo noise of the in-ear earphone is characterized in that an elastic yielding cavity is arranged on the inner side of the plug cap, one end of the sound transmission pipeline is connected with one end of the plug cap, and the other end of the sound transmission pipeline extends into the elastic yielding cavity.

The silica gel cover of prevention in-ear earphone popo noise as above, the portion of cup jointing is located the sound conduction pipeline stretches into the one end in elasticity chamber of stepping down.

The silica gel cover for preventing popo noise of the in-ear earphone is characterized in that the inlet of the sleeving part is a horn mouth gradually increasing towards the direction of the sound transmission pipeline.

The application still provides an in-ear earphone, including the earphone body, still include as above the silica gel cover of prevention in-ear earphone popo noise, silica gel cover detachably cover is located on the earphone body.

Compared with the prior art, the method has the following advantages:

this application embodiment is through set up the passageway of making an uproar of falling on the silica gel cover, the passageway intercommunication of making an uproar falls acoustic pipe and external for acoustic pipe keeps unanimous with external atmospheric pressure, effectively realizes especially making an uproar falling to the popo noise, and saves the design cost of little volume earphone in the aspect of leaking and making an uproar.

[ description of the drawings ]

In order to more clearly illustrate the technical solutions in the embodiments of the present application, the drawings needed to be used in the description of the embodiments are briefly introduced below, and it is obvious that the drawings in the following description are only some embodiments of the present application, and it is obvious for those skilled in the art to obtain other drawings based on these drawings without creative efforts.

Fig. 1 is a schematic perspective view of an embodiment of the present application.

[ detailed description ] embodiments

In order to make the technical problems, technical solutions and advantageous effects solved by the present application more clear and obvious, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

As shown in fig. 1, the embodiment of the present application provides an in-ear earphone, including the earphone body to and the silica gel cover of prevention in-ear earphone popo noise, silica gel cover detachably cover is located on the earphone body. The silica gel cover includes silica gel cover body 1, silica gel cover body 1 is including cup jointing portion 11, sound transmission pipeline 12 and stopper cap 13, set up the intercommunication on the cup jointing portion 11 sound transmission pipeline 12 and external passageway 14 of making an uproar falls.

At the in-process of wearing the earphone, because the earphone fills in behind the ear, if completely isolated with the ear chamber with external world, the ear chamber is too big with external atmospheric pressure differential pressure, can make the vibrations diaphragm of loudspeaker be in the distortion state, produces the noise during vibrations, and this scheme is through sheathe in silica gel and set up the passageway of making an uproar, passageway 14 intercommunication of making an uproar falls the sound transmission pipeline 12 and external world for sound transmission pipeline 12 keeps unanimous with external atmospheric pressure, effectively realizes especially making an uproar falls to the pop noise, and saves the design cost of little volume earphone in the aspect of making an uproar falls in the leakage.

Preferably, the socket 11 is an annular protrusion, and the noise reduction channel 14 is a groove formed inside the socket 11. Simple structure, and easy processing.

By way of one embodiment, and not limitation, the grooves are U-shaped in cross-section.

Further, the stopper cap 13 inboard is equipped with elasticity and steps down chamber 131, sound transmission pipeline 12 one end with stopper cap 13 one end is connected, and the other end stretches into in the elasticity chamber 131 of stepping down. Through elasticity lets a chamber 131, and the deformation space of silica gel cover is bigger, more can adapt to the not unidimensional duct.

Correspondingly, the sleeve joint part 11 is located at one end of the sound transmission pipeline 12 extending into the elastic abdicating cavity 131.

In order to make the assembly and disassembly of the silica gel sleeve smoother, the inlet of the sleeve joint part 11 is a horn mouth gradually increasing towards the direction of the sound transmission pipeline 12.

In summary, the present application has, but is not limited to, the following beneficial effects:

this application embodiment is through set up the passageway of making an uproar of falling on the silica gel cover, the passageway 14 intercommunication of making an uproar falls acoustic pipe 12 and external for acoustic pipe 12 keeps unanimous with external atmospheric pressure, effectively realizes especially making an uproar falling to the popo noise, and saves the design cost of little volume earphone in the aspect of leaking the noise reduction.

The foregoing is illustrative of one or more embodiments provided in connection with the detailed description and is not intended to limit the disclosure to the particular forms disclosed. Similar or identical methods, structures, etc. as used herein, or several technical inferences or substitutions made on the concept of the present application should be considered as the scope of the present application.
