Referring to fig. 1, the earplug cap for an in-ear earphone of the present invention is shown in a schematic cross-sectional view, and with reference to the accompanying drawings, the earplug cap for an in-ear earphone of the present invention comprises an elastic member 1 and a hard intermediate member 2, wherein the elastic member 1 comprises an inner layer 11 and an outer layer 12, and the inner layer 11 and the outer layer 12 are integrally connected through a platform 13; hard intermediate member 2 includes support piece 21 and joint spare 22, inlayer 11 encircle the cladding in support piece 21 outer wall, joint spare 22 is used for fixing earplug cap buckle on the earplug of in-ear earphone, the outer wall diameter of joint spare 11 is greater than support piece 21's outer wall diameter, inlayer 11 a terminal with joint spare 11 outer wall fixed connection makes platform 13 with constitute scalable clearance 3 between the outer wall of joint spare 22.

The utility model discloses an earplug cap use for in-ear earphone at first is connected with the in-ear earphone buckle through the joint spare 22 of stereoplasm middleware 2, and for guaranteeing buckle connection stability, the buckle structure phase-match of the in-ear earphone of adaptation should be followed to the shape and the buckle structure of joint spare 22, then fills in elasticity external member 1 the effect that the ear of user reaches the earplug. Because the earplug is the stereoplasm material usually, directly packs into the duct and can produce uncomfortable sense, can improve the comfort that the earplug was packed into in the duct through the earplug cap. The utility model discloses a stereoplasm intermediate part 2 presents the big structure of the little one end of one end for joint spare 22 is better connected with the earplug, the duct is filled in to the support piece 21 that the diameter is relatively less simultaneously, support piece 21 can play the effect of supporting elasticity external member 1 on the one hand, prevent that it from taking place to warp after long-term the use and reducing and wear the comfort, on the other hand, in the use, support piece 21 can guide elasticity external member 1 to fill in the duct gradually, prevent that the earplug cap from filling in the duct in-process because of the friction extrusion deformation production ear that expands or reduce the uncomfortable sense that causes with the duct laminating nature etc.. The utility model discloses an elasticity external member 1 adopts inlayer 11 and outer 12 bilayer structure to connect through 13 integral types of platform, can strengthen the third dimension of elasticity external member 1, simultaneously, inlayer 11 end with 11 outer wall fixed connection of joint spare make platform 13 with constitute scalable clearance 3 between the outer wall of joint spare 22, when using, especially fill in the in-process of duct at the earplug, can play fine exhaust step-down effect, avoid the earplug to fill in the duct in-process, because earplug cap extrusion inflation causes the uncomfortable sense of the interior distending pain of duct.

In a preferred embodiment, referring to fig. 1-3, the inner layer 11 of the elastic sleeve member 1 of the present invention is a hollow cylindrical tubular structure, and the diameter of the outer layer 12 gradually increases along the direction from the supporting member 21 to the fastening member 22, so that the whole elastic sleeve member 1 forms a shape similar to a horn with a small end and a large end, and when in use, the end with a relatively small diameter is firstly inserted into the ear canal. The platform 13 is arranged at one end of the outer wall of the inner layer 11 close to the clamping piece 22. As can be seen from the section view of the attached drawing 1, the inner layer 11 and the platform 13 form a T-shaped structure, and when in use, because the elastic sleeve member 1 has elastic deformation characteristics, the earplug cap is plugged into the ear canal, the inner layer 11 cannot deform under the action of the supporting piece 21, the platform 13 is extruded to generate inclined deformation, and at the moment, the platform 13 and the telescopic gap 3 formed between the outer walls of the clamping pieces 22 can play the effect of exhausting and relieving pressure, so that the air pressure in the ear canal is maintained at a relatively stable value, and the problems of ear expansion and extrusion of the earphone diaphragm caused by overhigh ear pressure value are prevented.

With continued reference to the cross-sectional view of the elastic sleeve 1 shown in fig. 3, the outer diameter of the inner layer 11 is smaller than the inner diameter of the outer layer 12, and an annular collapsible space 4 is formed between the inner layer 11 and the outer layer 12. The in-process that the auricle was plugged in to the earplug cap, outer 12 and the friction of auricle are received the extrusion, help outer 12 to take place the shape that the deformation made the earplug cap more laminate the auricle through the scalable space between inlayer 11 and the outer 12.

With reference to fig. 1 and fig. 2, the end of the supporting member 21 of the hard intermediate member 2 is recessed inside the elastic sleeve 1, and the end of the fastening member 22 of the hard intermediate member 2 protrudes from the end of the elastic sleeve 1 with the largest diameter of the outer layer 12. The clamping piece 22 can be conveniently installed on the earplug, and meanwhile, the support piece 21 is prevented from being overlong to damage the ear canal.

Referring to fig. 1, 4 and 5, an adhesive table 221 extends from an outer wall of the clip member 22 to a periphery of the support member 21, and a distal end of the inner layer 11 is fixed to the adhesive table 221 by gluing. The bonding stage 221 and the platform 13 are parallel to each other, and the retractable gap 3 is formed between the bonding stage 221 and the platform 13. Because platform 13 has elasticity, during the use, receive the extrusion with constitute the extrusion space between the bonding platform 221, wear to laminate more and can not crowded bloated duct.

The platform 13 is perpendicular to the outer wall of the inner layer 11. As can be seen from the section view of attached

drawing

1 and 3, the outer wall of the perpendicular inlayer 11 of platform 13 constitutes T style of calligraphy structure, and this kind of structure makes the space that the platform 3 warp from top to bottom (the upper and lower of here is for the spatial position that the attached drawing shows, and the one end that is close to support piece 21 is last, and the one end that is close to joint piece 22 is down) is the biggest, and its upper portion is scalable space 4, and the lower part is scalable clearance 3, and the earplug cap is filled in or is taken out the in-process of duct and not only can guarantee the circulation of air and prevent the ear that expands, plays certain supporting role moreover, avoids between inlayer 11 and the outer 12 degree of deformation to reduce the laminating nature of earplug cap.

Referring to fig. 1, 4 and 5, the clip member 22 is provided with a fastening hole 221 around, and is fixed to the earplug in use. Generally, according to the arrangement of the earplug product, the shape of the fastening holes 221 is set to be a concave hole slot or hole form, two, three or four fastening holes 221 are uniformly distributed around the clip member 22, preferably, as shown in the drawing, four fastening holes 221 are symmetrically arranged, so that the connection is more stable and convenient.

In a preferred embodiment, the earplug cap for an in-ear earphone of the present invention is usually made of a light and comfortable material, wherein the elastic member 1 is a silicone cap, and the hard intermediate member 2 is fixed to a plastic member in the middle of the silicone cap.

For better fitting the ear canal, as shown in fig. 1-3, the outer side surface of the elastic sleeve 1 of the present invention is formed by integrally forming a convex arc surface 121 and a concave arc surface 122. Compare in current earplug cap whole be spherical surface or whole even torus, the utility model discloses a 1 surfaces of elasticity external member are through transition change, and the structure in the duct of laminating more wears more comfortablely.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and additions can be made without departing from the principles of the present invention, and these improvements and additions should also be regarded as the protection scope of the present invention.
