Detailed Description

The utility model is further described with reference to the following examples.

In an embodiment of the earphone of the present invention, as shown in fig. 1 to 6, the earphone includes an earphone line 2 and a mounting hole 13 provided at a side portion of an earshell 1. The hole wall of the mounting hole 13 is provided with a limit groove 14 which is axially arranged along the mounting hole 13.

In the present embodiment, the earphone line 2 includes a sheath 202, a conductive wire 203 and a plug 201 electrically connected to the conductive wire 203, and the sheath 202 is fixedly sleeved at the junction of the conductive wire 203 and the plug 201 by injection molding.

The improvement is that the sheath 202 protrudes towards the end of the plug 201 to form a mounting part 204 which is sleeved on the outer side of the plug 201, a snap ring 21 is fixedly connected to the outer periphery of the mounting part 204, and a snap protrusion 22 extends outwards from the outer side surface of the snap ring 21. In an embodiment, in order to facilitate the insertion of the locking protrusion 22 into the limiting groove 14 of the mounting hole 13, the locking protrusion 22 is an isosceles trapezoid with a narrow top end and a wide bottom end, and the locking protrusion 22 of the isosceles trapezoid has an inclined surface capable of guiding the insertion of the locking protrusion 22 into the limiting groove 14.

As a modification, the top end face of the mounting hole 13 extends upwards to form a limit lug 11, and the top end face of the mounting hole 13 is also formed with a limit convex strip 12 positioned at the side part of the limit lug 11. Through setting up spacing sand grip 12 to can inject the turned angle of earphone cord 2, avoid earphone cord 2 to rotate for a long time and produce winding problem. In addition, in cooperation with the earphone cable 2 of the present embodiment, a snap ring 21 is fixedly connected to an outer peripheral side of the earphone cable 2, the snap ring 21 extends outward to form a snap projection 22, in an assembled state, the snap projection 22 passes through the limiting groove 14 and then is snapped to a top end surface of the mounting hole 13, and the snap projection 22 can limit a degree of freedom in outward pulling out of the earphone cable 2. After the convex clip 22 is inserted into the limit groove 14, the convex clip 22 is located on the top end surface of the mounting hole 13, and then the earphone cable 2 is rotated, so that the convex clip 22 is clamped between the limit convex block 11 and the limit convex strip 12 after crossing the limit convex strip 12, thereby limiting the rotational freedom degree of the earphone cable 2.

Compared with the prior art, the earphone line 2 of the application is provided with the snap ring 21 and the snap bosses 22, can be matched with the external earmuffs 1 to realize an anti-falling structure, is simple and compact in structure, and can solve the problem that the earphone line 2 is easy to fall off in the past.

In the present embodiment, the snap ring 21 may be formed integrally with the sheath 202, and in addition, the snap ring 21 may be bonded to the outer peripheral side of the sheath 202 by an adhesive, so that the earphone of the present embodiment can be used in different earphone lines 2.

In the present embodiment, two limiting protrusions 11 are provided, and the two limiting protrusions 11 are symmetrically and separately provided on the top end surface of the mounting hole 13.

In the present embodiment, two limit protrusions 12 are provided, and the two limit protrusions 12 are symmetrically and alternately provided on the top end surface of the mounting hole 13.

In the present embodiment, two snap projections 22 are provided, and the two snap projections 22 are provided symmetrically and at an interval on the outer peripheral side of the snap ring 21.

In this embodiment, the height of the position-limiting convex strip 12 is 0.5mm-1 mm.

As another improvement, a sealing groove 41 is formed at the top end of the peripheral side surface of the sheath 202, a sealing ring 42 is sleeved in the sealing groove 41, and the outer diameter of the sealing ring 42 is larger than that of the sheath 202. In an assembled state, the sealing ring 42 is fastened between the sheath 202 and the mounting hole 13, and the sealing ring 42 can play a certain damping role to further prevent the earphone line 2 from falling off.
