[ background of the invention ]

Many in-ear earphones are all furnished with corresponding earplug, the earplug cup joints on the earphone so that the user can wear the earphone firmly, however, everyone's ear canal structure's shape, size all differ, and current earplug formula earphone structure is because the earplug is not perfect in buffer function and design, so general application can make the external auditory canal feel oppression doubly often, and when in great ear stowage, its earplug and external auditory canal can not really closely produce the space again, lead to outside the lou tone quality of bass to worsen, also cause the earphone pine to take off simultaneously easily and drop, consequently, need an improved earplug to overcome prior art's not enough.

[ Utility model ] content

A primary object of the present invention is to provide an improved earplug which fits the ear canal and is comfortable to wear.

In order to achieve the above object, the utility model discloses can adopt following technical scheme: an earplug comprises an inner tube body and an outer cover body surrounding the inner tube body, wherein the inner tube body comprises a sound inlet end and a sound outlet end, the outer cover body extends from the sound outlet end to the sound inlet end, the inner tube body comprises a main body portion and an elastic bending portion, the elastic bending portion is connected with the main body portion and the outer cover body, and the bending portion comprises at least three bending portions.

Further, the bending part comprises a first section, a second section, a third section and a fourth section which are sequentially connected along the axial direction from the inner pipe body.

Further, the first section extends inwards from the main body part, the second section extends outwards from the first section, and the first section and the second section are connected to form a first bending part.

Furthermore, the third section extends inwards from the second section, and the second section and the third section are connected to form a second bending part.

Furthermore, the fourth section extends outwards from the third section, and the third section and the fourth section are connected to form a third bending part.

Further, the outer diameter of the third bent portion is larger than the outer diameter of the first bent portion and smaller than the outer diameter of the second bent portion.

Furthermore, the first section, the second section, the third section and the fourth section are all curves.

Further, the outer cover extends beyond the inner tube.

Further, the minimum wall thickness of the main body part is larger than the maximum wall thickness of the bending part, and the outer cover body has the same wall thickness.

Furthermore, the opening of the sound inlet end is tapered into a trumpet shape from outside to inside.

Compared with the prior art, the utility model has the advantages of: the bending part of the inner tube body comprises a plurality of bending structures, so that the earplug is easy to twist and deform, fits the auditory canal and is comfortable to wear.

[ detailed description ] embodiments

Fig. 1 to 2 show an earplug 100 according to the present invention. The earplug 100 includes an inner tube 110 and an outer cover 120 surrounding the inner tube 110, the inner tube 110 includes a sound outlet end 111 and a sound inlet end 112 opposite to the sound outlet end 111, the sound outlet end 111 is connected to an earphone (not shown), the outer cover 120 extends from the sound outlet end 111 to the sound inlet end 112, the outer cover is umbrella-shaped, and the outer cover and the inner tube are made of elastic materials.

The inner tube 110 includes a main body 210 and a flexible bending portion 220 connecting the main body 210 and the outer cover 120, wherein the bending portion 220 is adjacent to the sound outlet end 111. The bending portion 220 includes a first section 221, a second section 222, a third section 223 and a fourth section 224 which are sequentially connected along an axial direction from the inner tube 110, the first section 221, the second section 222, the third section 223 and the fourth section 224 are all curved, the first section 221 extends inward from the main body portion 210, the second section 222 extends outward from the first section 221, and the first section 221 and the second section 222 are connected to form a first bending portion 231. The third segment 223 extends inward from the second segment 222, and the second segment 222 and the third segment 223 are connected to form a second bending portion 232. The fourth segment 224 extends outwards from the third segment 223, and the third segment 223 and the fourth segment 224 are connected to form a third bending portion 233. The outer diameter D3 of the third bent portion 233 is greater than the outer diameter D1 of the first bent portion 231 and less than the outer diameter D2 of the second bent portion 232. In other embodiments, the number of the bending portions is not limited to this, and as long as the inner tube body is easy to twist and deform and fit the ear canal, the present disclosure is not limited to this, when a user wears the earplug, the bending portions 220 are deformed under stress, and the bending structures are easier to twist, so as to be suitable for various ear canals, and further achieve the airtight effect between the earplug and the ear canal, so that the earplug is comfortable to wear and is not easy to fall off.

The inner tube body 110 has a non-uniform wall thickness, wherein a minimum wall thickness of the body portion 210 is greater than a maximum wall thickness of the bending portion 220, and a smaller wall thickness makes the bending portion more susceptible to torsional deformation. In the axial direction of the inner tube 110, the extension length L1 of the outer cover 120 is greater than the extension length L2 of the inner tube 110, and the outer cover 120 has the same wall thickness from top to bottom. The inner tube 110 includes a socket region 113, a sound guide tube (not shown) of the earphone can be sleeved on the socket region 113, and an opening of the sound input end 112 is tapered from outside to inside to form a horn shape.

In the present case, flexion 220 has a plurality of structures of buckling and makes it have better torsional deformation ability, when the user will cup joint the earplug of earphone and fill in the duct, flexion atress production turns to, various elastic deformation such as twist reverse to adapt to various not unidimensional canals, reach the airtight effect of earplug and canal, wear comfortablely, and be difficult to drop.

It is to be understood, however, that even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, including details of structure and function, the disclosure is illustrative, and changes may be made in detail, especially in matters of shape, size and arrangement of parts within the principles as expressed by the broad general meaning of the terms in which the appended claims are expressed.
