In the description of the present invention, it is to be understood that the terms "upper", "lower", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on those shown in the drawings, and are used only for convenience in describing the present invention and for simplicity in description, and do not indicate or imply that the referenced devices or elements must have a particular orientation, be constructed and operated in a particular orientation, and thus, are not to be construed as limiting the present invention. It should be noted that when one component is referred to as being "connected" to another component, it can be directly connected to the other component or intervening components may also be present.

The technical scheme of the utility model is further explained by the specific implementation mode in combination with the attached drawings.

The embodiment of the utility model provides an earplug sleeve, which aims to reduce the problem that the earplug sleeve is easy to generate higher ear pressure in the wearing process, so that the wearing comfort of an earphone of a user is improved.

The earplug sleeve comprises a sound guide tube 1 for connecting an earphone and a plug cap 2 for plugging in an ear canal, wherein the front end of the sound guide tube 1 is connected with the front end of the plug cap 2, the sound guide tube 1 and the plug cap 2 form an annular pressure relief cavity 3 with an opening facing the earphone, and the annular pressure relief cavity 3 is communicated with the outside; the farther the plug cap 2 is from the sound guide tube 1, the larger the diameter of the plug cap 2 is, the larger the diameter of the plug cap is, and the plug cap 2 is divided into a sealing part 21 and a pressure relief part 22 in sequence from the smaller the diameter to the larger the diameter;

the sealing part 21 is used for sealing the auditory canal, the maximum diameter of the sealing part 21 is matched with the diameter of the auditory canal, the pressure relief part 22 is provided with a plurality of pressure relief through holes 221, and the pressure relief through holes 221 are communicated with the annular pressure relief cavity 3. It should be noted that the maximum diameter of the sealing portion 21 mentioned herein matches the diameter of the ear canal, which means that the maximum diameter of the sealing portion 21 matches the diameter of the ear canal where the cap 2 is worn.

It should be appreciated that the earplug cover is made of a flexible material and has a good elastic deformation capability.

Wherein, the sound guide tube 1 is generally connected with the sound outlet of the earphone for transmitting music.

The plug cap 2 is intended to be inserted into the auditory canal. Specifically, in the wearing process, the plug cap 2 gradually penetrates into the deep direction of the auditory canal, at this time, the pressure relief part 22 is firstly contacted with the auditory canal, at this time, the air in the auditory canal can still be released to the annular pressure relief cavity 3 through the pressure relief through hole 221, and is discharged out of the auditory canal through the annular pressure relief cavity 3; the gag 2 deepens gradually to the depths direction of duct, before the maximum diameter department of sealing part 21 forms sealed space with the duct, the equal normal discharge of air in the duct will greatly reduce the volume of the air that gets into the duct that the gag 2 drives like this, and the lifting value of ear pressure value is lower, has promoted user's earphone and has worn the comfort. In addition, it should be understood that the ear pressure value can be maintained within a proper range, which is equivalent to reducing the extrusion of the vibrating diaphragm of the earphone caused by the overhigh ear pressure value, and can effectively avoid the noise generated by the vibrating diaphragm of the earphone in the working process.

When the plug cap 2 enters the set wearing position, the periphery of the sealing part 21 is contacted with the auditory canal to form a relatively sealed space, and the influence degree of the music of the earphone on the external noise is reduced.

Optionally, pressure relief through holes 221 are annularly arrayed on pressure relief portion 22. It should be appreciated that the ear canal is not generally perfectly circular, and therefore, a plurality of vent holes 221 are provided in a circumferential array on the vent portion 22 to facilitate enhanced venting of air from the ear canal. Preferably, one corner of the diamond-shaped hole is aligned with the sealing portion 21 to improve the air leakage capability of the pressure leakage through-hole 221.

It will be appreciated that the pressure relief portion 22 deforms during insertion of the cap 2 into the ear canal until the cap is in place, and the diamond shape of the hole results in a softer pressure relief portion 22, which more flexible pressure relief portion 22 is more likely to vent air from the ear canal. In addition, it should be noted that the pressure relief through hole 221 may also be a circular through hole, a rectangular through hole, a triangular through hole, or a regular polygonal through hole; that is, the shape of the pressure relief through hole 221 may be set according to production needs as long as the pressure relief through hole 221 can discharge air from the ear canal.

Optionally, the pack further comprises an annular support 23, the annular support 23 being at an end of the pressure relief portion 22 remote from the sealing portion 21. It will be appreciated that the annular support portion 23 facilitates improved support of the cap 2 to provide better retention of the cap 2 in the ear canal.

Optionally, the sound guide tube 1 and the plug cap 2 are made of silica gel. The plug cap 2 made of silica gel has strong elastic deformation capability and is comfortable to wear.

Optionally, the sound guiding tube 1 is sleeved on the sound outlet of the earphone through the sound guiding hole 11, the front end of the sound guiding hole 11 is further provided with a deformation groove 111, and the wall thickness at the deformation groove 111 is smaller than that at the sound guiding hole 11.

In particular, by providing the deformation groove 111, the stopper cap 2 can be made more easily elastically deformable during wearing.

The wall thickness of the deformation groove 111 is thinner, which is equivalent to that the front end of the sound guide tube 1 has better deformation capability, and the application range of the plug cap 2 is wider due to the deformation capability of the sound guide tube 1.

Optionally, the outer side surface of the plug cap 2 away from the sound guide tube 1 is a convex arc surface. In particular, the design of the convex arcuate surface enables the diameter of the stopper cap to be varied gradually. It will be appreciated that the maximum diameter of the seal 21 may vary from population to population.

Optionally, the pressure relief portion 22 is annular, and the diameter of the pressure relief through hole 221 is equal to the width of the pressure relief portion 22, so that the pressure relief capacity can be further improved.

The above-mentioned embodiments are only used for illustrating the technical solutions of the present invention, and not for limiting the same; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
